Some evaporator matches may require some additional charge. See Tabular Data sheet provided in unit literature packet. If a calibrated charging cylinder or accurate weighing device is available, add refrigerant accordingly.

036-21544-001 Rev. B (1103) 11 MICROPROCESSOR CONTROL 1. COOLING/HEATING OPERATION Outdoor unit operation is activated by delivery of a 12VDC signal from the indoor unit. Cooling only units have 2 low voltage control wires from the indoor unit to the outdoor unit. The functions of these wires are: • Wire #1: Common • Wire #2: Initiates operation of the compressor and outdoor fan when 12VDC is supplied from the indoor unit. • Wire #3: Receives 12VDC from the indoor unit when set to the "Heat Mode".
036-21544-001 Rev. B (1103) 11 MICROPROCESSOR CONTROL C. Low Ambient Temperature Switch (LATS) - The purpose of this switch is to extend cooling operation in low outdoor temperatures as low as 25°. The outdoor unit uses a high side pressure switch to cycle the fan. When pressure drops to 165 PSI (+/-10), the switch opens and the fan stops. When pressure rises to 300 (+/- 10), the switch closes and the fan restarts. A jumper is factory installed in place of the low ambient pressure switch.

036-21544-001 Rev. B (1103) 13 REFRIGERANT SYSTEM SERVICE PORTS There are two service ports available to service technicians. One port is located at each of the two base valves. A. Liquid Line Base Valve Service Port. This port is used to evacuate the refrigerant line set when the ball valve is in the closed position. It may also be used to measure the liquid line pressure or, more accurately, the “saturated line” pressure during normal operation. 1.
