GEOTHERMAL HEAT PUMPS & ACCESSORIES

GEOTEC™ GV – SERIES HIGH EFFICIENCY GEOTHERMAL/WATER SOURCE, PACKAGED STEP-CAPACITY UPFLOW HEAT PUMP — R410A Engineered Features

Steel Cabinet: Galvanized 20 gauge zinc coated steel cabinet with baked-on enamel. Multi-Capacity Two-Stage: Simple thermostatic control seamlessly stages the compressor and indoor airflow rate between full and part load capacity operation without cycling the compressor. This helps to maximize comfort, humidity control, energy efficiency and overall reduction in compressor cycling for improved system life. Step Capacity Compressor: Copeland step-capacity scroll compressors are designed for increased efficiency, quieter operation and improved reliability. R-410A Refrigerant: Designed with R-410A (HFC) non-ozone depleting refrigerant. Liquid Line Drier: Protects system against moisture. Lockout Circuit: Built-in lockout circuit resets from the room thermostat. Provides commercial quality compressor protection. High Pressure Switch: Provides additional protection for the system. Control Panel: Can be reversed to other side for installation flexibility. Low Pressure Switch: Two switches provided. Factory wired switch is for ground water applications, alternate switch is field connected for ground loop applications.

H gh Effic ency Copper Coax al Water Coil: Water to refrigerant coil is completely insulated to prevent frost build-up at low temperature operation. Indoor Air Coil: Grooved copper tubing and enhanced louvered aluminum fin for maximum heat transfer and energy efficiency. Coil is constructed with special corrosion resistant hydrophilic fin stock with 2-layer coating. Filter Rack: Factory installed with 2" MERV 6 pleated filter. Thermostatic Expansion Valve: For wide range refrigerant control (2-way operation). Domestic Hot Water Heat Exchanger: Double wall vented heat exchanger, factory installed on all models - optional GVDM-26 pump kit required for hot water heating. Water Connections: All water connections on outside of cabinet with dual side connections. Brass full swivel double o-ring connection with 1" full flow ports. Electric Heat: Slide in Electric Heater Package - up to 18KW can be field installed. Variable Speed ECM Blower Motor: • High Efficiency • Soft starting - low noise on start up • Continuous fan - will operate at 50% of rated Stage 2 airflow Mild Weather Operation: Part Load Cooling Operation will operate at 20% reduced airflow

TYPICAL INSTALLATION Unit installs upright and hooks up

conveniently to supply water system. Ideal for closet, basement, or utility room installation. Requires very little floor space. Can be installed with or without return air duct.
