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 two-inch pleated filter is standard with each unit.
INSTALLATION INSTRUCTIONS WALL MOUNTING INFORMATION WARNING 1. Two holes for the supply and return air openings must be cut through the wall as shown in Figures 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.

WARNING A minimum of 1/4 inch clearance must be maintained between the supply air duct and combustible materials. This is required for the first 3 feet of ducting. It is important to insure that the 1/4 inch minimum spacing is maintained at all points.

WIRING – MAIN POWER WIRING – LOW VOLTAGE WIRING Refer to the unit rating plate for wire sizing information and maximum fuse or “HACR” type circuit breaker size. Each outdoor unit is marked with a “Minimum Circuit Ampacity”. This means that the field wiring used must be sized to carry that amount of current. Depending on the installed KW of electric heat, there may be two field power circuits required. If this is the case, the unit serial plate will so indicate.

START UP THESE UNITS REQUIRE R-410A REFRIGERANT AND POLYOL ESTER OIL. GENERAL: 1. Use separate service equipment to avoid cross contamination of oil and refrigerants. 2. Use recovery equipment rated for R-410A refrigerant. 3. Use manifold gauges rated for R-410A (800 psi/250 psi low). REMEMBER: When adding R-410A refrigerant, it must come out of the charging cylinder/tank as a liquid to avoid any fractionation, and to ensure optimal system performance.
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 PRESSURE SWITCH All J**A/J**L wall mounted air conditioner series models are supplied with a remote reset for the high and low pressure switch.
SEQUENCE OF OPERATION Alarm Relay Output COOLING – Circuit R-Y makes at thermostat pulling in compressor contactor, starting the compressor and outdoor motor. (See NOTE under Condenser Fan Operation if equipped with Low Ambient Control.) The G (indoor motor) circuit is automatically completed by the thermostat on any call for cooling operation or can be energized by manual fan switch on subbase for constant air circulation.
TROUBLESHOOTING FAN BLADE SETTING DIMENSIONS Shown in Figure 11 is the correct fan blade setting for proper air delivery across the outdoor coil. Refer to Table 1 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.
