Outstanding Standard Features

Colored And Numbered Wiring
Save time and money tracing wires and diagnosing the unit.

Compressors
Foundation™ contains the best compressor technology available to achieve the highest possible
performance.

Controls – Electromechanical
This 24-volt control includes the control transformer and contactor pressure lugs for power wiring.

Convertible Units
Foundation™ 7.5 to 12.5 ton units ship in the downflow configuration. Their convertible design makes it
easy to convert them to a horizontal airflow configuration without an additional kit.1

Discharge Line Thermostat

The high pressure controls and the discharge line thermostat signals are wired in series and connected
to the safety input of the LSD. The compressor contactor coil is connected to the ‘CC’ terminal of the
LSD. If the high pressure control switch or the discharge line thermostat is open, the 24 Vac signal to the
SI input of the LSD is interrupted and the compressor contactor coil supply is disabled by the LSD. It has
an automatic lockout. The high pressure controls and discharge line thermostats are wired in the system
protection detection port. If the high pressure control switch or the discharge line thermostat is open, the
main control board will turn off the compressor of the corresponding system. There is no automatic
lockout.

Efficiency
Product efficiencies meet the requirements of ASHRAE 90.1 - 2016.

Easy Access Low Voltage Terminal Board

Foundation™ Low Voltage Terminal Board is mounted outside the main electrical control cabinet. It is
extremely easy to locate and attach the thermostat control wiring and also test operation of all unit
functions. This is another cost and time saving installation feature.

Insulation
All panels in the evaporator section of the unit have foil-faced, glass fiber insulation. All base panels
have foil-faced, glass fiber insulation. All edges are either captured or sealed to ensure no insulation
fibers get into the airstream.

1. The 7.5 ton unit requires a conversion kit.

6 RT-PRC091F-EN
 Features and Benefits

Heat Exchanger
The cabinet features a tubular heat exchanger in heat capacities – all available for vertical and
horizontal discharge directions. The heat exchanger is fabricated using aluminized steel burners and
corrosion-resistant, aluminized steel tubes as standard on all models. As part of the heat exchanger
assembly, an induced draft blower is used to pull the gas mixture through the burner tubes. A direct
spark ignition system, which doubles as a safety device to prove the flame, is used to ignite the gas
mixture.

Locking Safety Device with Anti-Short Cycle Timer

This device monitors compressor safety switch trips to prevent short cycling, protecting the compressor.
A manual reset is required after a fourth safety switch trip.

Low Ambient Cooling

All Foundation units have cooling capabilities down to 0°F as standard.

Low Voltage Connections

The wiring of the low voltage connections to the unit and the thermostat is as simple as R-R, G-G, Y-Y,
and W-W. This simplified system makes it easy for the installer to wire.

Microchannel Condenser Coil

Microchannel condensing coils are all-aluminum coils with fully-brazed construction. This design
reduces risk of leaks and provides increased coil rigidity — making them more rugged on the jobsite.
Their flat streamlined tubes with small ports and metallurgical tube-to-fin bond allow for exceptional heat
transfer. Microchannel all-aluminum construction provides several additional benefits:
• Light weight (simplifies coil handling)
• Easy to recycle
• Minimize galvanic corrosion

Motors
All indoor fan motors are belt drive as standard.

Pressure Cutouts
Low and high pressure cutouts are standard on all Foundation™ models.

Quick-Access Panels
Remove screws (four or fewer) for access to the standardized internal components and wiring.

RT-PRC091F-EN 7
Features and Benefits

Quick-Adjust Fan Motor Mounting Plate

With the quick-adjust slider plate, the belt and sheaves can be quickly adjusted without moving the
mounted fan motor. This results in reduced time spent on routine maintenance.

Single Point Power

A single electrical connection powers the unit and all on-board options.

Single Side Service

Single side service is standard on all units.

Sloped Drain Pans

Every Foundation™ unit has a non-corrosive, sloped drain pan made of rigid PVC - standard on all
units.

LP Conversion Kit
LP kits are provided as standard with each GCC 090-150 unit for conversion of gas heat units from
natural gas to propane.

Variety of Options
Factory Installed Options
Oversized Motors
Multi-speed only – Factory installed oversized motors are available for high static applications.

Field Installed Options

Condensate Overflow Switch
A condensate overflow switch is available to shut the unit down in the event that the condensate drain
becomes clogged. This option protects the unit from water overflowing from the drain pan and entering
the base of the unit.

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.

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

Electric Heaters
Electric heat is available as a field installed option.

Low Leak Economizer with Fault Detection and Diagnostics

This economizer meets the damper leakage requirements for ASHRAE 90.1, IECC, and California Title
24 standards (3 cfm/ft^2 at 1.0 in. w.g. for outside air dampers and 4 cfm/ft^2 for return dampers).

Manual Outside Air Damper

A 0-50 percent manual air damper is available.

8 RT-PRC091F-EN
 Features and Benefits

Motorized Outside Air Damper

A 0–50 percent motorized outside air dampers is available.

Power Exhaust
This option is available on downflow units and provides exhaust of the return air, when using a downflow
economizer, to maintain proper building pressurization. This is an excellent option for relieving most
building overpressurization problems.

Barometric Relief
Designed to be used on downflow and horizontal configuration for standard and downflow low leak
economizer units, barometric relief is an unpowered means of relieving excess building pressure.
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.

Reference or Comparative Enthalpy

Measures and communicates humidity while maximizing comfort control.

Remote Potentiometer
When installed in the economizer control circuitry, this accessory provides a method to remotely adjust
the minimum damper position.

Roof Curbs
Available for downflow units. Only one roof curb for all 7.5 to 12.5 ton Foundation™ units simplifies curb
selection.

Thermostats
Available in programmable and non-programmable.

Through-the-Base Electrical Utility Access

An electrical service entrance shall be provided allowing access for both control and main power
connections inside the curb and through the base of the unit. This option will allow for field installation of
liquid-tight conduit and an external field installed disconnect switch.
Factory provided through the base openings simplify wiring and piping. Because these utility openings
frequently minimize the number of roof penetrations, the integrity of roofing materials is enhanced.

Through-the-Base Gas Piping (Gas Heat Units Only)

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.

Tool-less Hail Guards

Tool-less, hail protection quality coil guards shall be field-installed for condenser coil protection. This
option protects the condenser coil from vandalism and/or hail damage.

Other Benefits
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-PRC091F-EN 9
Features and Benefits

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

Outstanding Flexibility
The Foundation 7.5-12.5 ton units match the footprint of specific Carrier WeatherMaker™ units.

Rigorous Testing
All of Foundation’s designs were rigorously rain tested at the factory to ensure water integrity. 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. Factory shake tests were
used as part of the package design process to help assure that the unit arrives at the job site in top
condition.
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.

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.

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

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-PRC091F-EN 11
Selection Procedure
Cooling Capacity
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: 120 MBh
• Sensible Cooling Load: 96 MBh
• Airflow: 4000 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
• Accessories: 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.
120 MBh / 12 MBh = 10 Tons
3. shows that a GCC120A has a gross cooling capacity of 122.1 MBh and 96.3 MBh sensible capacity
at 4000 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 0.05 wg

Electric Heater Size kW from 0.07 wg

Total Static Pressure 0.47 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 has already accounted for the pressure drop for standard
filters and wet coils (see note below in ). Therefore, the actual total static pressure is 0.47 -
0.05 (from ) = 0.42 wg.
With 4000 cfm and 0.42 wg. shows 1.9 bhp for this unit. Note below the table is the formula to
calculate fan motor heat.
3-hp fan motor heat (MBh) = 2.90 x fan bhp + 0.4750
2.90 x 2.06 + 0.4750 = 5.435 MBh

Now subtract the fan motor heat from the gross cooling capacity of the unit:
Net Total Cooling Capacity = 122.1 MBh - 5.435 = 116.665 MBh.

12 RT-PRC091F-EN
 Selection Procedure

Net Sensible Cooling Capacity = 96.3 MBh - 5.435 = 90.865 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 100.0 MBh
4000 cfm
The electric heat accessory capacities are listed in . From the table, a 2 kW heater will deliver 109.2
MBh at 480 volts. In order to determine capacity at 460 volts, the heater voltage correction factor
from must be used. Therefore, 109.2 MBh x 0.94 (voltage correction factor) = 102.6 MBh.
Gas/electric: Fuel natural gas total heating load of 100 MBh. shows 125 MBh and 180 MBh input
models. The output capacities of these furnaces are 70 MBh and 100 MBh respectively. The
medium heat model with 100 MBh output best matches the building requirements.

Air Delivery Selection

External static pressure drop through the air distribution system has been calculated to be 0.38 inches
of water. From the 32 kW heater is 0.04 inches of water (0.38 + 0.04). Enter for a EBC120A4E0 at 4000
cfm and 0.42 static pressure. The standard motor will give the desired airflow at 758 rpm and rated bhp
of 1.89.

Notes:
1. The air distribution system has the greatest effect on airflow. The duct system is totally controlled by the contractor. For this reason, the contractor should
use only industry-recognized procedures.
2. Each ton of cooling requires between 300 and 450 cubic feet of air per minute (CFM), or 320 CFM nominally.
3. Duct design and construction should be carefully done. System performance can be lowered dramatically through bad planning or workmanship.
4. Air supply diffusers must be selected and located carefully. They must be sized and positioned to deliver treated air along the perimerter of the space. If they
are too small for their intended airflow, they become noisy. If they are not located properly, they cause drafts. Return air grilles must be properly sized to
carry air back to the blower. If they are too small, they also cause noise.
5. The installers should balance the air distribution system to ensure proper quiet airflow to all rooms in the home. This ensures a comfortable living space.
6. An air velocity meter or airflow hood can give a reading of system CFM.

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.
