has a policy of continuous product improvement, it reserves the right to change specifications and design without notice. The installation and servicing of the equipment referred in this booklet should be done by qualified, experienced technicians.

Always act in a responsible manner to conserve refrigerants for continued use even when acceptable alternatives are available. Refrigerant used in any type of air-conditioning or refrigerating equipment should be covered for reuse, recovered and/or recycled for reuse, reprocessed (reclaimed), or properly destroyed, whenever it is removed from the equipment. Never release to the atmosphere. Take extra care to properly maintain all service equipment directly supporting refrigerant service work such as gauges, hoses, vacuum pumps, and recycling equipment. Stay aware of unit enhancements, conversion refrigerants, compatible parts and manufacturer.s recommendations which will reduce refrigerant emissions and increase equipment operating efficiencies. Follow specific manufacturer.s guidelines for conversion of existing systems. 2 DIGITS 1 & 2 - PRODUCT TYPE GS = Ground Source Heat Pump DIGIT 3 - PRODUCT CONFIGURATION S = Split System DIGIT 4 - DEVELOPMENT SEQUENCE D DIGITS 5,6 & 7 - UNIT NOMINAL CAPACITY (MBH) 024 = 24.1 030 = 29.6 036 = 36.4 042 = 41.1 048 = 48.7 060 = 59.2 072 = 65.6 DIGIT 8 - VOLTAGE/HERTZ/ PHASE 1 = 208/230-60-1 DIGIT 9 - UNIT ARRANGEMENT 0 = Split Condensing Unit DIGIT 10 -DESIGN SEQUENCE C DIGIT 11 - OPEN DIGIT 0 = Open Digit DIGIT 12 - OPEN DIGIT 0 = Open Digit DIGIT 13 - DESUPERHEATER 0 = No Desuperheater 1 = With Desuperheater Model Number Description GS S D 036 1 0 C 0 0 1 2 0 T 5 10 15 DIGIT 14 - FREEZE PROTECTION 1 = 35 Degree Freezestat 2 = 20 Degree Freezestat DIGIT 15 - OPEN 0 = Open DIGIT 16 - BRAND C = Command Aire T = Trane 3 General Information The GSSD split unit has been ARI rated with the Trane TWE air handlers with ICM 2 variable speed motors to create a complete split system for residential applications. The GSSD equipment is completely assembled, piped, internally wired and test operated in the factory. The GSSD equipment is ETL and CSA listed. A prewired terminal strip is provided for field control wiring. The system water inlet and outlet connections are female 1-inch National Pipe Thread (NPT) swivel quick connectors with stainless steel stop ring to simplify field installation. The GSSD units are shipped with a pressurized dry nitrogen holding charge to ensure clean components. All equipment has easy to read decals and labels to aid in service of unit, identifying port locations and indicating caution areas. Safety The GSSD was designed with protection of unit components in mind. High and low pressure cutouts are included to prolong the life of the compressor. A 35 degrees F freezestat for non-antifreeze applications or 20 degrees F freezestat for closed loop with antifreeze is included to protect against fluid freezing in the unit.s water heat exchanger. All safety devices with exception of compressor internal overload are connected to a lockout relay to turn off the compressor, the loop pumps and the desuperheater pump if a problem is incurred. Note: The lockout relay may be reset by cycling power to the unit at the disconnect or thermostat system switch. Brass Loop Water Connections Two 1-inch brass swivel connectors on the units help eliminate the need for a backup wrench when tightening the loop water connections. Gaskets for the brass connections can be found inside a cloth bag located in the electrical compartment. Cabinet The cabinet is constructed of galvanized heavy gauge steel. The finish is applied by an electrostatic powder spray system in the color of crushed ice. The top, front half of the diagonal cabinet is removable for access to all of the internal components by removing only two screws. All panels are insulated with 1/2-inch thick, neoprene backed, acoustical fiberglass insulation Desuperheater (Optional) The double wall vented desuperheater uses heat off of the discharge line of the compressor to preheat a home.s domestic hot water. Hot water is provided at virtually no cost to the user during the cool...
