GT Series High Efficiency Geothermal/Water Source Step-Capacity Heat Pump — R-410A Ground Water Application: Water Temp 45° to 75° Ground Loop Application: Temp Range 25° to 110° The GT Series Geothermal/Water Source Heat TYPICAL INSTALLATION APPLICATIONS Pump delivers economical year-round comfort by Compressor, Blower and A Coil Sections stack utilizing nature’s most abundant and efficient vertically for upflow and counterflow solar energy collector – the earth. The GT installations. Blower and A Coil Sections can Series heat pumps are designed for low water be remotely mounted in attics or crawl spaces flow rates and offer cooling efficiencies up to providing horizontal right or left opportunities. 29.1 EER and heating efficiencies up to 4.8 COP on ground water, and cooling efficiencies up to 24.9 EER and heating efficiencies up to 4.4 COP on ground loop. All units are shipped prewired for fast, easy installation in residential or commercial buildings. Engineered Features Steel Cabinet: Indoor Air Coil: Filter Rack (Optional): Galvanized 20 gauge zinc coated steel Grooved copper tubing and enhanced Accessory kit with 1" filter (reversible for left or cabinet with baked-on, textured enamel louvered aluminum fin for maximum heat right side access for upflow installations). which allows it to withstand 1000 hours of transfer and energy efficiency. salt spray exposure. Accessory Electric Duct Heater Option: Coil is constructed with special corrosion 5, 10, 15 and 20KW nominal size.

This is hot water per day are dependent upon the Thermostatic Expansion Valve: seamlessly controlled internal of the unit above variables, and in general can range up For wide range refrigerant control controls with no required user intervention. to 125 gallons per day for a nominal 24,000 (2-way operation). BTU heat pump system, and up to 375 Water Connections: gallons per day for a nominal 60,000 BTU High Pressure Switch: All water connections on outside of heat pump system in the cooling mode, Provides additional protection for the system. cabinet. Brass full swivel double o-ring offering a 100% energy savings over connection with 1" full flow ports. Low Pressure Switch: conventional electric water heaters. During the winter months when the heat pump is Two switches provided. Factory wired Refrigerant Connections: operating in the heating mode, less hot water switch is for ground water applications, Special self-sealing fittings are used with 3' is available, but at the same time, the electric alternate switch is field connected for line set for stacked upflow or downflow water heater will consume less electricity. ground loop applications. applications, and line sets up to 50' available for horizontal or dual-fuel Control Panel: applications. Mid-level for easy access. Blower section includes transformer and blower control. Service Access Ports: Permits service pressure check of High Efficiency Coaxial Water Coil in discharge and suction pressures. either Copper or Cupronickel Water to refrigerant coil is completely insulated to prevent frost build-up at low Form No. S3443-211 temperature operation.
