/////// UNIT MODES OF OPERATION
Cooling Operation:
The Bard WA Series products offer single stage compressor cooling operation using R410A refrigerant. Copper tube/Aluminum hydrophilic
green fin coils are used to provide high efficiency and easy serviceability. Scroll compressor technology delivers years of quiet, reliable
operation. Economizer vent options are available for increased energy efficiency during cooling operation when outdoor conditions are
favorable.

Heating Operation:
The Bard WA Series products offer optional single or two stage heating operation using resistance heaters. Circuit breaker disconnect
protection is standard in all units equipped with electric heat.

Mechanical Dehumidification (Hot Gas Reheat) Operation:

Mechanical Dehumidification provides an energy efficient way to remove humidity from the indoor air stream without over cooling or
overheating the indoor space. The Bard W30 through W72 Series products offer optional dehumidification operation that removes
moisture from air entering the unit. A three-way valve, reheat coil, and electronic expansion valve (EEV) are standard with all models. The
dehumidification circuit incorporates an independent heat exchanger coil in the supply air stream. This coil reheats the supply air after
it passes over the cooling coil without requiring the electric resistance heater to be used for reheat purposes. This results in very high
mechanical dehumidification capability from the air conditioner on demand without using electric resistance reheat (electric heat is available
for heating purposes). Airflow during dehumidification is reduced resulting in quiet and comfortable operation.

Ventilation:
The Wall-Mount product provides the perfect platform to not only cool and heat an indoor area, but also provide a means of bringing outdoor
air into the building. By including ventilation in the Wall-Mount, expensive costs associated with additional outdoor air systems can be
avoided. The Bard WA Series products offer optional ventilation operation that brings outdoor air into the structure, and vents can be factory
or field installed. Ventilation can be used to bring in outdoor air for occupants, save energy by using outdoor air for free cooling, or positively
pressurize a structure. Exhaust air options allow room air to be vented outdoors when fresh air is being brought into the structure. Energy
recovery options are also available for occupied structures to save energy when ventilation is necessary regardless of outdoor temperature.

Filtration and Indoor Air Quality:

Providing the best air filtration solution is important to occupants and equipment inside a room or structure. Bard provides several filter
options based on MERV filtration, and also other solutions to improve indoor air quality.

Balanced Climate Operation:

Balanced Climate is a great feature to remove additional room humidity during cooling operation. All units include this feature as an optional
method of having a separate cooling stage that uses a lower indoor blower speed. Remove the Y1/Y2 jumper, and install a two stage cooling
thermostat. Once enabled, a first stage of increased humidity removal and lowered cooling capacity will extend unit runtime and increase
latent (humidity removal) capacity. Second stage operation will use the standard blower speed. This is a great option where additional
humidity reduction is a benefit during normal cooling operation.
Note: Balanced Climate is not recommended for applications where room temperatures will typically be lower than 72°F or duct static will
cause airflow to be below rated CFM amounts provided in the Airflow CFM chart in this document. Low Ambient Control use is required for
Balanced Climate operation. Hot Gas Reheat is recommended for high humidity environments that require moisture removal without cooling or
applications that require a large amount of ventilation air for occupied areas.

Low Outdoor Temperature Cooling Operation:

Equipment cooling often requires indoor areas to remain cool regardless of outdoor temperature. If your application requires operation of the
compressor to provide cooling below 65° outdoor conditions, then just like any other HVAC system, a low ambient control (LAC) kit must be
installed. The LAC will help maintain higher refrigerant pressure during compressor operation at lower outdoor temperatures. This is achieved
by limiting outdoor fan operation based on low side system pressure. As temperatures decrease outdoors, outdoor fan use will continue to
decrease. Applications that require cooling functionality from 0°F to -40°F outdoor temperatures must use economizer cooling operation.

Note: The LAC kit also includes a freeze stat installed on the unit indoor evaporator coil. The freeze stat helps monitor the indoor evaporator
coil temperature and will cycle compressor operation when temperatures below freezing are indicated. Use of Balanced Climate or applications
where indoor airflow will be reduced require the use of the LAC kit to help maintain adequate evaporator coil temperatures.

High Outdoor Temperature Cooling Operation:

The Bard WA Series products are designed and tested to function when used in higher outdoor temperature areas. Wall-Mount products utilize
large, efficient condenser coils with high airflow condenser fan systems to save energy and lower high side refrigerant pressures. It is always
important to follow all clearance guidelines supplied in the unit dimension section of this specification, and additional information provided in
the user manual. Properly cleaning the condenser coil using a regular maintenance schedule along with filter changes will help maintain unit
operation during high outdoor ambient temperature use. Always follow maintenance procedures provided in the user manual and installation
instructions provided with your Bard product.

/////// INDOOR EC MOTOR BLOWER SPEEDS
Indoor airflow is measured in Cubic Feet per Minute (CFM) and will vary based on static pressure created by supply duct work, return duct work, unit filter type,
deflection of the air by the supply grille, or any other restriction of air entering or leaving the unit. The indoor fan motor of the WA series product has the capabil-
ity of running at multiple speeds. Indoor blower speed is selected inside the control panel area using the speed tap terminal block.

Blower and Vent Only Speed: The WA series uses this speed when fan only (G) or ventilation operation (A) is used. See airflow performance chart for CFM
amount. If cooling and heating speed is adjusted from LO to MED or HI, the Blower and Vent Only speed will not change.

Balanced Climate Speed: The WA series uses this speed when the Balanced Climate option (Y1) or mechanical dehumidification option (D) is used. The Bal-
anced Climate speed reduces unit airflow by approximately 30% which increases moisture removal (latent capacity) during cooling operation. Units with the hot
gas reheat dehumidification option also use this speed to increase moisture removal when running in dehumidification mode. Unit capacity performance when
using Balanced Climate can be calculated using the -30% capacity multipler factor provided in the Cooling Application Data. Unit capacity performance for hot
gas reheat dehumidification units can be found in the Dehumidification performance supplimental manual #7960-811. See airflow performance chart for CFM
amount.

To use Balanced Climate, remove the jumper between Y1 and Y2 on the low voltage terminal strip. A 2 stage cooling thermostat is then used to control blower
airflow stages. Be sure to follow all guidelines provided in the installation manual. A controls kit that includes a low ambient control (LAC) must be used for
Balanced Climate Operation if ventilation options are to be used or cooling operation will occur below a 60° outdoor temperature. Balanced Climate can be used
for duct free and ducted applications below ESP total static shown in indoor airflow performance charts. Balanced Climate provides increased moisture removal
during the cooling cycle, but is not a replacement for optional mechanical dehumidification. Optional mechanical dehumidification provides moisture removal
without significantly cooling the space being conditioned. Mechanical dehumidification is highly recommended for applications requiring indoor humidity control
for schools, public areas, agricultural, pharmaceutical, and areas with high outdoor humidity and varying indoor heat load.

LO Speed (Default): The WA series uses this speed by default when using standard cooling (Y2) or heating operation (W1/W2). This speed is labeled as LO on the
speed selection terminal strip inside the unit control panel. All units ship with cooling and heating operation at LO cooling and heating speed, and provides the
optimal airflow amount for normal use. See airflow performance chart for CFM amount.

MED Speed (User Selectable): This speed is user selectable when using standard cooling (Y2) or heating operation (W1/W2). This speed is labeled as MED on
the speed selection terminal strip inside the unit control panel. The MED speed tap provides an increase in unit airflow per the airflow performance chart.

HI Speed (User Selectable): This speed is user selectable when using standard cooling (Y2) or heating operation (W1/W2). This speed is labeled as HI on the
speed selection terminal strip inside the unit control panel. The HI speed tap provides maximum unit airflow per the airflow performance chart.

/////// INDOOR AIRFLOW STATIC AND UNIT PERFORMANCE

The airflow amount that passes through the unit is very important when considering cooling capacity and proper unit operation. Restriction of the amount of
air passing through the unit is called external static pressure (ESP). As the amount of air passing through the unit is restricted, the ESP value increases. This
will have a direct impact on how heating and cooling equipment performs when used in an application. It is important to have a professional HVAC contractor,
distributor, or technician complete a duct static calculation if supply or return ducts are used with the WA series unit. Unit filter static must also be calculated
into the total ESP value.

Supply Duct Static: Supply duct static will include duct work connected to the unit supply opening, supply registers, filtration installed in the supply duct, or any
other device in the supply airstream that will restrict airflow. All ducts must be sealed to reduce duct air leakage, and flex duct work must not include restriction
due to installation. Duct static must be calculated by a HVAC professional and include all factors of the duct design.

Return Duct Static: Return duct static will include duct work connected to the unit return opening, return registers, filtration installed in the return duct, or any
other device in the return airstream that will restrict airflow. All ducts must be sealed to reduce duct air leakage, and flex duct work must not include restriction
due to installation.Duct static must be calculated by a HVAC professional and include all factors of the duct design.

Unit Filter Static: The WA series uses a unit filter installed before the indoor blower assembly that filters both indoor air from the room and outdoor air entering
through the ventilation device. When additional filtration is required (higher MERV rating), additional static will need to be added to the total external static
pressure (ESP). The following chart is to be used to estimate additional static pressure for a installed clean filter.

FILTER CODE FILTER MERV RATING FILTER STATIC INCHES WC. FILTRATION LEVEL
X MERV 2 0” WC Low Filtration, 1” Thickness Disposable Media.
W MERV 2 -.02” WC Low Filtration, 1” Thickness Permanent Media.
P MERV 8 .03” WC Average Filtration, 2” Thickness Pleated Disposable Media.
M MERV 11 .05” WC Above Average Filtration, 2” Thickness Pleated Disposable Media.
A, B, N MERV 13 .08” WC High Filtration, 2” Thickness Pleated Disposable Media.

Calculating Total External Static Pressure: Supply duct static, return duct static, unit filter static, and any other source of additional static pressure are added
together. Once this is calculated, the actual unit airflow amount can be reviewed by using the Indoor Airflow CFM charts provided.

Total External Static Pressure Calculation:

Supply Duct Static + Return Duct Static + Filter Static + Additional External Static = Total External Static Pressure (ESP)

Non-Ducted Applications: Applications that do not include supply or return ducts inside the structure, use Bard supplied supply and return louvers, and do not
have additional sources of external static will typically reflect rated airflow amounts shown in the Indoor Airflow CFM charts. Additional filter static must still be
added as necessary to the rated airflow total external static pressure (ESP). Field supplied supply and return louvers must match Bard supplied supply and return
louvers to achieve shown in the Indoor Airflow CFM charts. Adjustment of 4-way deflection supply louver may effect unit supply airflow. See louver deflection and
throw characteristics provided in this document.

/////// INDOOR EC MOTOR OPTIONS FOR HIGH RESISTANCE GROUND APPLICATIONS

Today’s ECM motor technology used in HVAC equipment provides a higher level of energy efficiency and more options for installers than older PSC motor designs.
However, high resistance ground applications and locations where power supplied to the unit may not be clean (dirty power) require special consideration. Bard
recommends ordering the motor isolation option “R” for new 460V products where high resistance grounding or dirty power may be present. A kit for 460V prod-
ucts can also be ordered Bard Part #8620-330 that can easily be installed to help avoid issues related to high resistance grounding or dirty power sources.

Capacity Multiplier Calculation: Capacity multipliers are used to estimate unit capacity performance when airflow rates are decreased or
increased compared to rated airlow. Rated airflow is the standard CFM amount used for capacity and efficiency calculations. Airflow rates
may be effected by external static pressure (ESP) from supply ducts, return ducts, advanced filter options, or use of additional blower speeds.
See unit airflow charts for additional information on unit airflow at different indoor blower speeds, filter static levels, and indoor airflow using
Balanced Climate operation.
Example: Due to additional supply duct static, the actual supply airflow CFM for a installed W72 unit is 10% lower than the rated airflow
shown in the blower performance chart. We want to know the actual BTUH amount of the unit at 85/72°F indoor and 100°F outdoor
temperature for this application. The following formula will be used to calculate actual unit BTUH at the new supply airflow CFM amount:
Rated unit BTUH capacity x capacity multiplier factor = actual unit BTUH capacity.
Example: 75,000 rated Total BTUH x .97 capacity multiplier = 72,750 actual Total BTUH.
Example: 47,300 rated Sensible BTUH x .95 capacity multiplier = 44,935 actual Sensible BTUH.

 Maximum size of the time delay fuse or circuit breaker for protection of field wiring conductors.
 “Minimum Circuit Ampacity” values are to be used for sizing the field power conductors. Refer to the National Electrical code (latest version), Article 310 for power conductor sizing.

CAUTION: When more than one field power circuit is run through one conduit, the conductors must be derated. Pay special attention to Note 8 of Table 310 regarding Ampacity
Adjustment Factors when more than three current carrying conductors are in a raceway.

IMPORTANT: While this electrical data is presented as a guide, it is important to electrically connect properly sized fuses and conductor wires in accordance with the National
Electrical Code and all local codes.

Note: MOCP (Maximum Overcurrent Protection) value listed is the maximum value as per UL 60335 calculations for MOCP (branch-circuit conductor sizes in this chart are
based on this MOCP). The actual factory installed Overcurrent Protective Device (Circuit Breaker) in this model may be lower than the maximum UL 60335 allowable
MOCP value, but still above the UL 60335 minimum calculated value or Minimum Circuit Ampacity (MCA) listed.

/////// FIELD GENERATOR USE

Generator power is often used in the field for critical cooling and heating applications. When using generator power it is important to
understand the capability of the generator used. Review and follow all instructions and guidelines provided with the generator. The following
must be considered when selecting a generator provide power to HVAC equipment;
• When calculating the kW size of the generator, it is important to use the MCA values of the unit models being used. This value can be
found in the electrical specifications section of this document.
• When calculating inrush current that the generator will see during unit startup, use the Locked Rotor Amp values of the unit being used.
This value can be found in the general specifications section in the beginning of this document.
It is important to remember to review power usage for all units that will be operating off of the generator. It is also important to consider all
equipment that will consume power (not just HVAC equipment) when calculating a generator size. Bard does offer a Secure Start kit Bard part
#8551-014 for units up to a 5 ton cooling capacity that is designed to reduce inrush current load during cooling mode.

/////// FRESH AIR DAMPER AND COMMERCIAL VENTILATOR SPECIFICATIONS
“X” Vent Code Option – Standard Barometric Fresh Air Damper without Exhaust (FAD-NE)
The barometric fresh air damper without exhaust is a standard feature on all models, and can be ordered pre-
installed from Bard or may be field installed with the FAD-NE vent kit. Fresh air dampers are typically used when
a small amount of outdoor air is required in a room or structure when the indoor blower is on. The intake damper
opens when the indoor blower is operational and negative pressure in the vent area of the unit pulls the blade
open. When the blade is open, the damper allows outdoor air to be brought into the structure. Pins are provided
that allow for airflow adjustment. See FAD-NE airflow charts provided in this specification for airflow amounts.
Room air exhaust is not provided with the FAD-NE vent.
The barometric fresh air damper without exhaust includes the following options:
• The damper opens when the indoor blower is operational.
• The vent provides up to 25% of the total airflow rating of the unit.
• Adjustable blade pins allow different amounts of outside air to be introduced into the building and can be
easily locked closed if required.

operation based on outdoor conditions and includes an easy to use interface with an LCD display screen. Bard has pre-programmed the JADE from the factory to
provide standard settings that apply for common installations.
The following basic setup menu items are available through the JADE menu settings:
• Mixed Air Temperature: This set point is used to control the air temperature that is provided by the economizer assembly. The mixed air temperature is set
from the factory to provide optimal cooling performance during economizer use. Default setting is 53°F and can be adjusted between 38°F and 65°F.
• Low T Lock: This set point is used to lock out compressor operation when outdoor temperature is extremely low. Default setting is 0°F and can be adjusted
between -45°F and 80°F.
• Dry bulb Set point (ECON-DB only): Provides the maximum outdoor temperature for economizer use. Default setting is 60°F and can be adjusted between
48°F and 80°F.
• Enthalpy Curve Set point (ECON-WD only): Provides the enthalpy (temperature and humidity) boundary curves for economizer use. Default setting is ES3 and
can be set between ES1 and ES5.
• Minimum Position: Used to set the outdoor ventilation amount to be brought into the room or structure when the unit (A) terminal is energized. Default
setting is 2VDC and can be set between 2VDC and 10VDC.
• Demand Control Vent set point (DCV): DCV is available when 2-10VDC signal is received from a CO2 sensor or other device. This is set to the maximum
allowable CO2 level for the space when used with a CO2 sensor. Default setting is 1100ppm and can be adjusted between 500 to 2000ppm. Default setting
is recommended, and CO2 level is normally adjustable at the CO2 sensor.

General Ventilation Option Guidelines

Applying heating and cooling equipment for various applications in the field requires careful planning to ensure the results provide are acceptable for occupants
and heat generating equipment inside a room or structure. Products must be reviewed to meet all national, state, and local codes. When providing ventilation
air to an indoor area, it is important that the equipment heating and cooling capacity be sized properly for the amount outdoor air being brought into the
room or structure. Building pressurization requirements for specified pressurization amounts may require additional exhaust dampers, intake dampers, or
fan pressurization systems. Avoid bringing in excessive ventilation amounts when it is not required per the application. Building codes may require special
consideration regarding fire suppression systems, building pressurization, and other ventilation needs. Thermostats, CO2 sensors, and multiple unit lead/lag
controllers that are used to control the equipment including ventilation must be reviewed per the application requirements. Follow all codes and standards that
apply to the location where the equipment will be used, and review ASHRAE recommendations and guidelines for the application.

/////// CONTROLS OPTIONS DEFINITIONS

Unit controls include safety devices and accessories that can be used to customize the Bard Wall-Mount for uses in multiple applications. Controls can be supplied
from the factor or field installed. The below listing provides a description of the controls options available for the Bard WA Series unit.

Hi Pressure Control (HPC) - The high-pressure control is standard in all units, and interrupts compressor operation if high side refrigerant pressures exceed
switch settings. The switch is normally closed (NC) and opens during a high-pressure event. Events that can cause the switch to open include poor condenser
coil cleaning maintenance, poor filter maintenance, condenser fan failure, or a leak/restriction in the refrigeration system.

Low Pressure Control (LPC) - The low-pressure control is standard in all units, and interrupts compressor operation if low side refrigerant pressures reach
an extremely low level. The switch is normally closed (NC) and opens during a low-pressure event. Events that can cause switch use include poor filter
maintenance, reduced or restricted airflow, evaporator fan failure, or a restriction in the refrigeration system.

Compressor Control Module (CCM) - The compressor control module is standard in all air conditioner units, and interrupts compressor operation if the high- or
low-pressure switch circuits are opened or a low incoming voltage event (brownout) occurs. See unit manual for further details regarding the operation of the
high and low-pressure control and how it interacts with the CCM to help protect the system from unit damage during a low-pressure event. The CCM includes a
diagnostic light, brownout protection, and a make-on-break and delay on make timer.

Alarm Relay (ALR) - The alarm relay is an optional accessory that can be factory or field installed in the unit control panel. It consists of a relay that is energized
based on a signal from the compressor control module. Once energized, the alarm relay will provide both normally open (NO) and normally closed (NC) contacts
on the low voltage terminal strip to indicate an event has locked out compressor operation.

Low Ambient Control (LAC) - The low ambient control is an optional accessory that can be factory or field installed in the unit condenser section. When installed,
the LAC monitors high side system pressures and helps maintain a specific pressure range during compressor operation. To maintain high side system
pressures, condenser fan operation is either turned on and off in cycles, or the speed of the condenser fan modulates. Low ambient controls are recommended
for applications where compressor cooling is required at lower outdoor temperatures below 60°F (15.5°C). Models with the low ambient control option also
include a freeze stat attached to the coldest refrigerant circuit of the indoor evaporator coil. If freezing temperatures are sensed by the freeze stat, compressor
operation is disabled momentarily to help prevent ice buildup on the indoor evaporator coil.

Crankcase Heater (CCH) - The crankcase heater is an optional accessory that can be field installed around the base of the compressor. When installed, the CCH
provides heat to the compressor base when the compressor is not operational. Heating the compressor helps prevent oil migration when the unit is not running.
Standard compressor functionality does not require the crankcase heater, but it is recommended for compressor operation in extremely cold environments
including northern Canada.

Outdoor Thermostat (ODT) - The outdoor thermostat is an optional accessory that can be field installed in the unit control panel and condenser section. The
outdoor thermostat measures outdoor temperatures and includes relay contacts (NC) breaking the compressor signal during cold outdoor conditions. The
thermostat is in the control panel area and the sensor bulb is mounted to the fan shroud in the outdoor condenser section. Adjustment range is 0°F to 50°F.
Default setting is 10°F.

PTCR Start Kit - Field installed option only. PTCR (Precision Temperature Coefficient Resistor) start kit includes the start device and wires needed for
installation. The device is located inside the unit control panel near the compressor capacitor and provides an increase in starting torque. The PTCR Start Kit is
not normally required when a clean, stable power source is available for the unit. The kit can only be used in 230 Volt single phase units.

Start Capacitor and Potential Relay Start Kit - Field installed option only. The kit includes a start capacitor and relay that is energized during startup of the
compressor. The capacitor, relay, and needed wires are provided in a metal enclosure that is field installed in the outdoor section attached to the back. The
Start Capacitor Kit is not normally required when a clean, stable power source is available for the unit. The kit can only be used in 230 Volt single phase units.
Start capacitor kit cannot be used with the PTCR start kit installed.

/////// CONTROLS OPTIONS DEFINITIONS
DDC Controls Kit - The DDC controls kit is an optional accessory that can be factory or field installed. It consists of multiple sensors and switches that provide
feedback to a field supplied DDC control (not included) or advanced thermostat (not included). The DDC controls kit consists of the following:
• Dirty Filter Indicator Switch. See below description.
• Discharge Air sensor. This is a temperature probe installed in the supply airstream of the product. It measures the air temperature leaving the unit
and provides a 10k @ 77°F (Type 2) signal to a field supplied controller.
• Indoor Airflow Switch. This is a pressure differential device located in the entering and leaving airstream of the indoor blower. Normally open (NO)
relay contacts are provided that indicate when the indoor blower is operating, and supply air is leaving the unit.
• Compressor Current Indicator Switch. This is amp sensing device located on one of the power lines leading to the compressor. Normally open (NO)
relay contacts are provided that indicate when the compressor is operating during cooling mode. Amp load required to close the contacts is user
adjustable.

Refer to user manual 7960-849 (W18 thru W36) and 7960-855 (W42 thru W72) for further information on components, wiring, and location of all devices in
the unit.

Dirty Filter Switch Indicator (DFS) - The dirty filter indicator switch is an optional accessory that can be factory or field installed in the unit filter area. The switch
measures pressure before and after the filter. During a restricted filter event, normally closed (NC) contacts will open indicating the filter requires maintenance.
Once maintenance is complete, the switch is manually reset to indicate maintenance is complete. Pressure differential is adjustable to match user preference
for filter replacement.

/////// NON-DUCTED SUPPLY GRILLES - SPREAD AND THROW CHARACTERISTICS
One of the most important setup procedures for non-ducted supply applications is to adjust the 4 way supply grille blade positions. Placement of
equipment, occupants, the thermostat, and room size can all play an important role in deciding how the conditioned supply air must be directed in
an indoor area. The chart below may be used as a reference tool to help with this process.
