SHIPPING DAMAGE Upon receipt of equipment, the carton should be checked for external signs of shipping damage. If damage is found, the receiving party must contact the last carrier immediately, preferably in writing, requesting inspection by the carrier’s agent. GENERAL The equipment covered in this manual is to be installed by trained, experienced service and installation technicians. The refrigerant system is completely assembled and charged. All internal wiring is complete.
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 1 or 2. Figure 1 is for models WA4823, and WA6023. Figure 2 is for Models WA4822 and WA6022. 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. WARING Fire hazard can result if 1/4 inch clearance to combustible materials for supply air duct is not maintained.

FIGURE 5 ELECTRIC HEAT CLEARANCE SIDE SECTION VIEW OF SUPPLY AIR DUCT FOR WALL MOUNTED UNIT SHOWING 1/4 INCH CLEARANCE TO COMBUSTIBLE SURFACES. MIS-277 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 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. All models are suitable only for connection with copper wire.

START UP IMPORTANT INSTALLER NOTE For improved start up performance wash the indoor coil with a dish washing detergent. CRANKCASE HEATERS These units are not provided with crankcase heat. These units utilize scroll compressors which do not require crankcase heat in this application. HIGH PRESSURE SWITCH The models are supplied with a remote reset high pressure switch. If tripped, this pressure switch may be reset by turning the thermostat off then back on again. SERVICE HINTS 1.
High Pressure Switch and Lockout Sequence ADJUSTMENTS If the high pressure switch opens, the compressor contactor will de-energize immediately. The lockout timer will go into a soft lockout and stay in soft lockout until the high pressure switch closes and the delay on break time has expired. If the high pressure switch opens again in this same operating cycle the unit will go into manual lockout condition and the alarm relay circuit will energize. Recycling the wall thermostat resets the manual lockout.
TROUBLESHOOTING FAN BLADE SETTING DIMENSIONS REFRIGERANT CHARGE Shown in Figure 10 is the correct fan blade setting dimension for proper air delivery across the outdoor coil. The correct system R-22 charge is shown on the unit rating plate. Optimum unit performance will occur with a refrigerant charge resulting in a suction line temperature (6” from compressor) as shown in Table 7.
