DUCT WORK FILTERS All duct work, supply and return, must be properly sized for the design airflow requirement of the equipment. Air Conditioning Contractors of America (ACCA) is an excellent guide to proper sizing. All duct work or portions thereof not in the conditioned space should be properly insulated in order to both conserve energy and prevent condensation or moisture damage. A 1-inch throwaway filter is standard with each unit. The filter slides into position making it easy to service.
INSTALLATION INSTRUCTIONS WALL MOUNTING INFORMATION 1. Two holes for the supply and return air openings must be cut through the wall as shown in Figure 3A - 3C. 2. On wood frame walls, the wall construction must be strong and rigid enough to carry the weight of the unit without transmitting any unit vibration. 3. Concrete block walls must be thoroughly inspected to insure that they are capable of carrying the weight of the installed unit.

START UP THESE UNITS REQUIRE R-410A REFRIGERANT AND POLYOL ESTER OIL. REMEMBER: When adding R-410A refrigerant, it must come out of the charging cylinder/tank as a liquid to avoid any fractionation, and to insure optimal system performance. Refer to instructions for the cylinder that is being utilized for proper method of liquid extraction. GENERAL: 1. Use separate service equipment to avoid cross contamination of oil and refrigerants. 2. Use recovery equipment rated for R-410A refrigerant. 3.
START UP (Continued) IMPORTANT INSTALLER NOTE PHASE MONITOR For improved start up performance wash the indoor coil with a dish washing detergent. All units with three phase scroll compressors are equipped with a 3 phase line monitor to prevent compressor damage due to phase reversal. HIGH & LOW PRESSURE SWITCH All J**H wall mounted air conditioner series models are supplied with a remote reset for the high and low pressure switch.
SEQUENCE OF OPERATION COOLING – Circuit R-Y makes at thermostat pulling in compressor contactor, starting the compressor and outdoor motor. The G (indoor motor) circuit is automatically completed on any call for cooling operation or can be energized by manual fan switch on subbase for constant air circulation. HEATING – A 24V solenoid coil on reversing valve controls heating cycle operation.

TROUBLESHOOTING SOLID STATE HEAT PUMP CONTROL TROUBLESHOOTING PROCEDURE 1. NOTE: A thorough understanding of the defrost cycle sequence is essential. Review that section earlier in this manual prior to troubleshooting the control. Turn on AC power supply to unit. 2. Turn thermostat blower switch to “fan on” – the indoor blower should start. (If it doesn’t, troubleshoot indoor unit and correct problem.) 3. Turn thermostat blower to “auto” position. Indoor blower should stop.
CHECKING TEMPERATURE SENSOR OUTSIDE UNIT CIRCUIT 1. Disconnect temperature sensor from board and from outdoor coil. 2. Use an ohmmeter and measure the resistance of the sensor. Also use ohmmeter to check for short or open. 3. Check resistance reading to chart of resistance. Use sensor ambient temperature. (Tolerance of part is ± 10%.) 4. If sensor resistance reads very low, then sensor is shorted and will not allow proper operation of the heat pump control. 5.
TROUBLESHOOTING FAN BLADE SETTING DIMENSIONS Shown in Figure 12 is the correct fan blade setting for proper air delivery across the outdoor coil. Refer to Table 5 for unit specific dimension. Any service work requiring removal or adjustment in the fan and/or motor area will require that the dimensions below be checked and blade adjusted in or out on the motor shaft accordingly.
