ACCESSORIES (SHIP LOOSE) • Condensate Pump PG Rev 1 0/1 0 SMALL SYSTEMS DIRECT EXPANSION FAN /COIL MODULE DATAMATE STANDARD FEATURES EVAPORATOR COIL Constructed of copper tubes in a staggered tube pattern. Tubes are expanded into continuous corrugated aluminum plate type fins. Galvanized steel condensate drain pan is located under the coil. REFRIGERATION SYSTEM Single refrigeration circuit, includes an externally equalized expansion valve, filter drier, liquid line solenoid valve, and quick - connect female couplings on both the suction and liquid lines. Each female coupling is provided with an access valve connection. The module is precharged with refrigerant and sealed. FAN ASSEMBLY Is a quiet, direct drive two-speed fan assembly with centrifugal type, double width, double inlet blowers, and includes permanently lubricated bearings. CONTROLS Micro Processor based design includes 8 key membrane keypad for set point and program control, unit on /off mounted in a decorative enclosure for wall mounting. CABINET AND CHASSIS The chassis is constructed of galvanized steel for strength and corrosion resistance, and is designed for easy installation and service access. Painted removable exterior panels allow access to the electric box or refrigeration components for service or maintenance. Return and discharge air grilles are heavy duty steel with baked enamel finish. Discharge grille can easily be reversed to change air direction. Evaporator module is designed for either floor or wall mounting. FILTERS Cleanable filters, located within the cabinet and serviceable without shutting down the system. OPTIONAL FEATURES REHEAT Electric low watt tubular reheat element with non - corrosive metal sheath provides one stage of non - ionizing reheat to maintain room dry bulb temperature. STEAM GENERATING CANISTER HUMIDIFIER Includes a replaceable steam generating canister with integral fill cup, fill and drain valves, and built -in 1" (25.4mm) air gap (backflow prevention). System automatically fills and drains as well as maintains the required water level based on conductivity. PRECHARGED REFRIGERANT LINE SETS Consist of one liquid line and one insulated suction line of soft copper tubing. Both lines are pre-charged with R-407C refrigerant. Each line has one male quick - connect coupling and one female quick- connect coupling with an access valve connection. Available in 15 ft. (4.6m) and 30 ft. (9.1m) lengths for interconnection of remote located condenser module. Maximum recommended line set distance between evaporator and condenser modules is 45 ft (13.7m) CONDENSATE PUMP Has a capacity of 67 GPH (253 I /h) for 230V 60Hz units, 60 GPH (227 I /h) for 208V 60Hz units, or 55 GPH (208 I /h) for 220V 50Hz units at 10 ft (30 kPa) of head. Pump is complete with integral float switch, discharge check valve, pump, motor assembly and reservoir. Assembly mounts on the right end of the evaporator (indoor) module. Auxiliary pump float automatically shuts off unit if pump discharge line clogs or pump fails. REFRIGERANT - LINE SWEAT ADAPTER KIT Contains two suction and two liquid line compatible fittings that allow field- supplied inter - connecting refrigerant lines to be used. 277 VOLT POWER SUPPLY SYSTEM Requires field installed transformer (37.5 amps) for evaporator module. For self contained water /glycol system use one 37.5 amp transformer for 1 1/2 and 2 ton system and 50 amp for 3 ton system. REMOTE TEMPERATURE AND HUMIDITY SENSORS Include sensors mounted in an attractive case with 30 ft. (9m) of cable.
