This option shall have all piping necessary including, black steel, manual gas shut-off valve, elbows, and
union. This assembly will require minor field labor to install.

Field Installed Options

CO2 Sensor - Demand Control Ventilation (DCV)
Demand-controlled ventilation (DCV) is a control strategy that responds to the actual demand (need) for
ventilation by regulating the rate at which the HVAC system brings outdoor air into the building. A CO2
sensor measures the concentration (parts per million, ppm) of CO2 in the air. As the CO2 concentration
changes, the outside air damper modulates to meet the current ventilation needs of the zone. DCV is a
passive system; direct control of the indoor fan is not possible with standard or low leak economizers.
The CO2 sensor kit is available as a field installed accessory.

Crankcase Heaters (25 Tons)

These band heaters provide improved compressor reliability by warming the oil to prevent migration
during off-cycles or low ambient conditions.

Economizer - Horizontal
Economizers are equipped with either dry bulb or reference or comparative enthalpy sensing. These
economizers provide free cooling as the outdoor temperature and/or humidity decreases. Correctly
installed, they offer a valuable energy savings.

High Altitude Kit

downflow units to prevent water from blowing into the ductwork.

Easy to Install, Service and Maintain

Because today’s owners are very cost-conscious when it comes to service and maintenance,
Foundation was designed with direct input from service contractors. This valuable information helped to
design a product that would get the service technician off the job quicker and save the owner money.
Foundation does this by offering outstanding standard features enhanced by a variety of factory and

RT-PRC060N-EN 11
Features and Benefits

field installed options, multiple control options, rigorously tested proven designs and superior product
and technical support.

Outstanding Flexibility
The Foundation unit has the ability to adapt to specific Carrier WeatherMaker™ models without costly
adapter curbs. This will save contractors money and make the installation an ease.

Rigorous Testing
All of Foundation’s designs were rigorously rain tested at the factory to ensure water integrity.
Foundation units incorporate either a one piece top or the Trane-Tite-Top (T3). Each part of the top
overlaps in such a way that water cannot leak into the unit. These overlapped edges are gasketed and
sealed to ensure superior water integrity.
Actual shipping tests were performed to determine packaging requirements. Units were test shipped
around the country to determine the best packaging. Factory shake and drop tests were used as part of
the package design process to help assure that the unit arrives at the job site in top condition.
Rigging tests include lifting a unit into the air and letting it drop one foot, assuring that the lifting lugs and
rails hold up under stress. For the microchannel coils, the supplier will perform the leak check at 450
psig. The completely assembled refrigerant system is leak tested at a minimum of 225 psig with a
refrigerant and nitrogen mixture.
All parts are inspected at the point of final assembly. Sub-standard parts are identified and rejected
immediately. Every unit receives a 100% unit run test before leaving the production line to make sure it
lives up to rigorous Trane requirements.

Application Considerations
Application of this product should be within the cataloged airflow and cooling considerations.

Barometric Relief
This product line offers an optional barometric relief damper for use in conjunction with economizer
option. This accessory consists of gravity dampers which open with increased pressure. As building
pressure increases, the pressure in the unit return air section also increases, opening the dampers and
relieving the conditioned space.
Notes:
• The effectiveness of barometric relief damper during economizing operation is system
related.
• Pressure drop of the return air system should be considered to control building
pressurization.

Clearance Requirements
The recommended clearances identified with unit dimensions should be maintained to ensure adequate
serviceability, maximum capacity and peak operating efficiency. Actual clearances which appear
inadequate should be reviewed with local Trane sales personnel.

Complete Coat™ Microchannel Condenser Coil

The cathodic epoxy type electrodisposition coating is formulated for high edge build to a number of
different types of heat exchangers. The coating is selected to provide excellent resistance and durability
to corrosive effects of alkalies, acids, alcohols, petroleum, seawater, salt air, and corrosive
environments. This coating shall be available on microchannel condenser coils.

Condensate Trap
The evaporator is a draw-through configuration. A trap must be field provided prior to start-up on the
cooling cycle.

Heating Operation
The heat exchanger is manufactured with aluminized steel.
To prevent condensation within the heat exchanger, do not exceed 50 percent outside air or a minimum
mixed air temperature of 40°F.

Optional Stainless Steel Heat Exchanger

The optional stainless steel heat exchanger is manufactured with 409 stainless steel tubes and 439
stainless steel burners. To prevent corrosion and prolong heat exchanger reliability, the minimum mixed
air temperature allowed across the heat exchanger is 40°F. Whenever high outside air or outside
applications exist, this option should be utilized.

Low Ambient Cooling

The Foundation line features low ambient cooling down to 45°F. The following options need to be
included/considered when low ambient applications are required: continuous fan operation, crankcase
heaters, or low pressure bypass timer. Contact your local Trane Representative for more assistance
with low ambient cooling applications.

Unit Pitch
These units have sloped condensate drain pans. Units must be installed level. Any unit slope must be
toward access side of the unit.

RT-PRC060N-EN 13
Selection Procedure
Cooling Capacity
Note: Cooling capacity procedure is the same for cooling (E) and gas/electric (G).
1. Calculate the building’s total and sensible cooling loads for the building at design conditions. Use
the following calculation methods or any other standard accepted method.
Factors used in unit selection:
• Total Cooling Load: 180 MBh
• Sensible Cooling Load: 126 MBh
• Airflow: 6000 cfm
• Electrical Characteristics: 460/60/3
• Summer Design Conditions: Entering Evaporator Coil: 80ºF DB/67ºF WB
• Outdoor Ambient: 95ºF
• External Static Pressure: 0.38 in. wg
• Rooftop – downflow configuration
• Efficiency: 14 SEER
• Accessories: Economizer, Roof Curb, Electric Heat
2. As a starting point, a rough determination must be made of the size of the unit. The final selection
will be made after examining the performance at the given conditions. Divide the total cooling load
by nominal Btuh per ton (12 MBh per ton); then round up to the nearest unit size.
180 MBh / 12 MBh = 15.0 tons
3. Table 10, p. 26 shows that a ECC180A4 has a gross cooling capacity of 187.2 MBh and 143 MBh
sensible capacity at 6000 cfm and 95 DB outdoor ambient with 80 DB, 67 WB air entering the
evaporator.
Find capacity at intermediate conditions not in the table
When the design conditions are between two numbers that are in the capacity table, interpolation is
required to approximate the capacity.
Note: Extrapolation outside of the table conditions is not recommended.
4. In order to select the correct unit which meets the building’s requirements, the fan motor heat must
be deducted from the gross cooling capacity. The amount of heat that the fan motor generates is
dependent on the effort by the motor - cfm and static pressure. To determine the total unit static
pressure you add the external static pressure to the additional static related by the added features:

External Static Duct System 0.38 wg

Standard Filter 2 in. from Table 29, p. 41 0.05 wg

Economizer (100% Return Air) from Table 29, p. 41 0.04 wg

Electric Heater Size 36 kW fromTable 29, p. 41 0.07 wg

Total Static Pressure 0.55 wg

Note: Reference heating capacity section on this page for determination of heater size. No additional static add for gas/heat
exchanger.

Note: The Evaporator Fan Performance Table 10, p. 26 has already accounted for the pressure
drop for standard filters and wet coils (see note below in Table 10, p. 26). Therefore, the
actual total static pressure is 0.55 - 0.05 (from ) = 0.50 wg.
With 6000 cfm and 0.50 wg. Table 10, p. 26 shows 1.37 bhp for this unit. Note below the table is the
formula to calculate fan motor heat.

14 RT-PRC060N-EN
 Selection Procedure

3.15 x bhp = MBh

3.15 x 1.37 = 4.32 MBh

Now subtract the fan motor heat from the gross cooling capacity of the unit:
Net Total Cooling Capacity = 187.2 MBh - 4.32 = 182.88 MBh.
Net Sensible Cooling Capacity = 143 MBh - 4.32 = 138.68 MBh.
5. Compare your resulting capacities to the building load. If the performance will not meet the required
load of the building’s total or sensible cooling load, try a selection at the next higher size unit.

Heating Capacity
Note: Heating capacity procedures DIFFER for cooling (E) and gas/electric (G) units.
1. Calculate the building heating load.
2. Size the system heating capacity to match the calculated building heating load. The following are
building heating requirements:
460 volt/3 phase Power Supply
Total heating load of 115.0 MBh
6000 cfm
The electric heat accessory capacities are listed in Table 31, p. 42. From the table, a 36 kW heater
will deliver 122.94 MBh at 480 volts. In order to determine capacity at 460 volts, the heater voltage
correction factor from Table 32, p. 43 must be used. Therefore, 122.94 MBh x 0.94 (voltage
correction factor) = 115.6 MBh.
Gas/electric: Fuel natural gas total heating load of 195 MBh. Table 30, p. 42 shows 250 MBh and
350 MBh input models. The output capacities of these furnaces are 203 MBh and 284 MBh
respectively. The low heat model with 203 MBh output best matches the building requirements.

Air Delivery Selection

Note: Air Delivery procedures is the same for cooling (E) and gas/electric (G) units.
External static pressure drop through the air distribution system has been calculated to be 0.50 inches
of water. From Table 29, p. 41 static pressure drop through the economizer is 0.04 and the 36 kW
heater is 0.07 inches of water (0.38 + 0.04 + 0.07). Enter for a ECC180A4 at 6000 cfm and 0.50 static
pressure. The standard motor with the low static drive accessory at 622 rpm will give the desired airflow
at a rated bhp of 1.37.

Controls
Economizer Controls
The standard equipment offering is a fixed dry bulb changeover control. In addition, there are two
optional controls, Reference Enthalpy Control and Comparative Enthalpy Control.

Reference Enthalpy Control

Replaces the dry bulb control with a wet bulb changeover controller which has a fully adjustable
setpoint. Enthalpy control offers a higher level of comfort control, along with energy savings potential,
than the standard dry bulb control. This is due to the additional wet bulb sensing capability.

Comparative Enthalpy Control

Comparative Enthalpy replaces the standard dry bulb control with two sensors that compare total heat
content of the indoor air and outdoor air to determine the most efficient air source. This control option
offers the highest level of comfort control, plus energy efficiency, available.

Remote Potentiometer
Minimum position setting of economizer can be remotely adjusted with this accessory.
