WARNING ELECTRICAL SHOCK HAZARD Failure to follow this warning could result in personal injury or death. Before installing, modifying or servicing system, turn OFF the main (remote) electrical disconnect device. There may be more than one disconnect device. Refer to unit rating plate for the required supply voltage. Depending on the model, required supply voltage will be: 208/230 V, 3-phase, 60 Hz. or 460 V, 3-phase, 60 Hz. Outdoor units are approved for use with copper conductors only. Do not use aluminum wire. Refer to unit rating plate for minimum circuit ampacity and circuit protection requirements. Grounding Permanently ground unit in accordance with the National Electrical Code and local codes or ordinances. Use a copper conductor of the correct size from the grounding lug in control box to a grounded connection in the service panel or a properly driven and electrically grounded ground rod. Supply Voltage Wiring Connections Make all outdoor electrical supply (Line Voltage) connections with raintight conduit and fittings. Most codes require a disconnect switch outdoors within sight of the unit. Consult local codes for special requirements. Route electrical supply (Line Voltage) wiring through knockout hole in bottom of Control Box. Connect two power wires to Contactor and one power wire to Blue lead wire (use wire nut). Connect ground wire to Ground Lug. Refer to Wiring Diagram on unit and Figure 9. Figure 9 208/230 V and 460 V Electrical Supply (Line Voltage) Connections DISCONNECT PER NEC AND/OR LOCAL CODES CONTACTOR GROUND LUG FIELD GROUND WIRING FIELD POWER WIRING 11 13 L1 L3 L2 BLUE LEAD WIRE Phase Monitor Relay Board The Phase Monitor Board detects the sequence of the three phase electrical system, and a relay breaks the Y (call for cooling) control signal if the phasing is incorrect. Additionally, the board will detect the loss of voltage on any of the three phase inputs and break the Y signal in the same way. An LED on the board displays the following status: Red LED ON - Normal function, relay contact closed. Red LED Blinking - Abnormal function, relay contact open. Red LED OFF - No 24 VAC control power present at board. NOTE: Units with Comfort Alert Diagnostics device have phase monitor feature built in. Figure 10 Phase Monitor Relay Board Thermostat Wiring Connections Route thermostat wiring through rubber grommet in bottom of Control Box. Low voltage lead wires are provided in the control box for connection to thermostat wires (use wire nuts). Refer to Wiring Diagram on unit and Figure 11 for low voltage wiring examples. NOTE: Use No. 18 AWG (American Wire Gage) color-coded, insulated (35 °C minimum) wire. If thermostat is located more than 100 feet (30.5 m) from unit as measured along the control voltage wires, use No. 16 AWG color-coded wires to avoid excessive voltage drop.

DEFROST THERMOSTAT The defrost thermostat is factory installed on a short tube stub extending from the coil end plate. Refer to Figure 12 and confirm that the thermostat is securely fastened in place on the tube stub. Figure 12 Defrost Thermostat FEEDER TUBE TUBE STUB DEFROST THERMOSTAT COIL B. DEFROST CONTROL BOARD The defrost board is a time/temperature control which includes a field-selectable time period between defrost cycles of 30, 60, or 90 minutes (quick-connects located at board edge, factory set at 90 minutes). Defrost mode is identical to cooling mode except that outdoor-fan motor stops and second-stage heat is turned on to continue warming conditioned space. Initially, the defrost cycle timer starts when the contactor is energized and a 24 VAC signal is present on the T1 terminal. Then the defrost cycle begins when the defrost thermos...
