Waterside Economizer

WARNING

Hazardous

Voltage!

Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/tagout procedures to ensure the power can not be inadvertently energized. Failure to disconnect power before servicing could result in death or serious injury.

The following steps were sequenced to aid in the installation and mating of a water side economizer to a water- source heat pump (GEH 1/2 to 5 ton).

1Remove the control side service panel of the water-source heat pump unit.

2Remove rubber isolation grom- mets from the return-air section. Place them in a convenient loca- tion.

3Attach ducted panel to the water-

source heat pump unit with six factory provided Torx® head screws. This panel is shipped loose with the water-source heat pump but must be field installed to the unit.

systems be made via 3-screws spaced evenly across the top,

3-screws spaced evenly across the bottom (installed immediate- ly after hanging the unit), and 2- screws on each side.

Step 4

5Install the 18-inch steel braided hose between the upper most piping connection of the econo- mizer, and the water-in of the heat pump. The hose is shipped loose with the water-side econo- mizer.

6Install the SUPPLY and RETURN hoses to the (1) 2-position valve’s threaded connection (2) water- out threaded connection of the water-source heat pump.

7VERIFY

The control board for the water side economizer is located at the back of the control box. The tem- perature rating of this board is factory set to 55ºF.

For units with boilerless (electric heat) control and water side economizer, the boilerless con- trol board is factory set to 45ºF.

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.
