Installation Power Wiring

Field Installed Power Wiring

Power wiring to the equipment must conform to National and Local Electric Codes (NEC) by a professional electrician.

WARNING

Live Electrical

Components!

During installation, testing, ser- vicing and troubleshooting of this product, it may be necessary to work with live electrical compo- nents. Have a qualified licensed electrician or other individual who has been properly trained in handling live electrical compo- nents perform these tasks. Failure to follow all electrical safety pre- cautions when exposed to live electrical components could re- sult in death or serious injury.

Verify that the power supply available is compatible with the unit’s name- plate. Use only copper conductors to connect the power supply to the unit.

CAUTION

Use Copper Conductors Only!

Unit terminals are not designed to accept other types of conduc- tors. Failure to use copper con- ductors may result in equipment damage.

Main Unit Power Wiring

A field supplied disconnect switch must be installed at or near the unit in accordance with the National Elec- tric Code (NEC latest edition).

Location of the applicable electric service entrance for HIGH (line volt- age) may be found on the unit sub- mittal at the front of this manual (pages 10 through 47).

The high voltage connection is made at the 1K1 contactor or 1TB1 power block inside the unit control box. See Figure 8. Refer to the customer con- nection diagram that is shipped with the unit for specific termination points.

Provide proper grounding for the unit in accordance with the local and na- tional codes.

Control Power Transformer

The 24-volt control power transform- ers are to be used only with the acces- sories called out in this manual. Transformers rated greater than 50 VA are equipped with internal circuit breakers. If a circuit breaker trips, turn OFF all power to the unit before at- tempting to reset it.

WARNING

Hazardous Voltage!

Disconnect all electric power, in- cluding remote disconnects be- fore servicing. Follow proper lockout/tagout procedures to en- sure the power can not be inad- vertently energized. Failure to disconnect power before servic- ing could result in death or seri- ous injury.

The transformer is located in the control panel.

GEV, GEH specifications

Trane has long been a leader in the HVAC industry, and their GEH and GEV series of heat pumps are a testament to their commitment to innovation and efficiency. These models are designed to provide substantial energy savings while maintaining exceptional performance, making them ideal choices for both residential and commercial applications.

The Trane GEH and GEV heat pumps feature advanced variable-speed technology, which allows them to adjust their output to match the current heating or cooling demand. This adaptability not only enhances comfort by maintaining a consistent indoor temperature but also leads to significant energy savings by reducing unnecessary energy consumption during partial-load conditions. By running more efficiently at lower speeds, these units reduce wear and tear on components, extending the lifespan of the system.

One of the defining characteristics of the GEH and GEV models is their high SEER (Seasonal Energy Efficiency Ratio) and HSPF (Heating Seasonal Performance Factor) ratings. These ratings demonstrate the units' ability to provide efficient heating and cooling throughout the year, contributing to lower energy bills. The use of R-410A refrigerant is another key feature, as it is both environmentally friendly and efficient, ensuring that these systems meet stringent regulatory standards while delivering reliable performance.

Installation flexibility is another highlight of the Trane GEH and GEV series. These units are designed to work seamlessly with existing HVAC systems, making retrofitting straightforward. Their compact design allows for easy placement, even in tight spaces, without compromising performance. Additionally, Trane's commitment to quality is evident in the construction of these heat pumps, as they are built to withstand harsh weather conditions and provide reliable service year after year.

Moreover, both the GEH and GEV models are equipped with integrated smart controls that simplify operation and maintenance. These controls allow homeowners and facility managers to monitor energy usage, adjusting settings remotely and scheduling maintenance checks to maximize efficiency. This technology not only enhances user experience but also promotes energy conservation through intelligent management.

In summary, Trane's GEH and GEV heat pumps stand out for their variable-speed technology, high efficiency ratings, installation flexibility, and smart controls. These features make them an ideal solution for those seeking a reliable, energy-efficient heating and cooling option, reflecting Trane's dedication to performance and sustainability.
