Features and Benefits

Dependable Design

Sound
Quiet operation is achieved through design. All units have thermal/acoustical insulated cabinets to attenuate compressor noise. Compressors are internally isolated to reduce vibration noise.

Compressor
The high efficiency hermetic compressor helps assure quiet, reliable and efficient operation.

Filter Drier
This unit is also equipped with a filter drier to dehydrate and clean the system, adding to the life of the unit.

Heat Exchanger
The exclusive refrigerant to liquid heat exchanger is a helical coil and shell design. The heat exchanger serves as a flooded evaporator/accumulator in the heating mode and a receiver in the cooling mode.

Expansion Valve
All units are equipped with a balanced port, bi-directional thermal expansion valve. The valve precisely meters the refrigerant flow through the circuit. No check valves are required.

Safety
This unit was designed with safety and maximum protection in mind. High and low pressure cutouts are included to protect the compressor. A freezestat is included to protect the unit from unusually cold waterflow or no waterflow conditions. The lockout relay will shut the entire unit off if there is a problem.

Easy Installation

Loop Pump(s)

Loop pump(s) are 208-230/60/1, six amps maximum, field connected to the pump relay.

Easy Serviceability and Maintenance

Access Panels
The unit has a service door and the top is removable for access to all components.

Transformer
The unit is supplied with a 40 VA transformer.

Control Box
The control box is amply sized to facilitate any troubleshooting or service work that might be required.

Service Ports
High and low side service ports are external to the unit. This simplifies accessing refrigerant pressures and saves service time.

System Benefits

The geothermal heat pump system consists of:

• The water source heat pump
• The ground heat exchanger made of high density thermoplastic pipe (guaranteed 25 years or more by many manufacturers)
• A low wattage circulating pump

In the heating mode, the closed loop heat exchanger absorbs heat from the earth (typically 50 to 70 F) and is compressed by the heat pump to a higher temperature. An antifreeze solution may be added to the ground loop heat exchanger to enhance the heating operation. In the cooling mode, the heat pump extracts heat and moisture from the air and rejects the heat to the cooler ground.

Trane's high efficiency residential water-source heat pumps offer EERs up to 20. Moderate earth temperatures translate into the highest comfort levels in cooling from increased dehumidification and higher supply air temperatures in heating.

The self-contained unit is entirely within your home, much like a refrigerator, avoiding outside weather extremes, and field refrigerant connections.
