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.
FRESH AIR INTAKE All units are built with fresh air inlet slots punched in the service panel. If the unit is equipped with the fresh air damper assembly, the assembly is shipped already attached to the unit. The damper blade is locked in the closed position. To allow the damper to operate, the maximum and minimum blade position stops must be installed. See Figure 2.
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 3. 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. WARNING Fire hazard can result if 1/4 inch clearance to combustible materials for supply air duct is not maintained. See Figure 3. 3.
WIRING — LOW VOLTAGE WIRING The electrical data lists fuse and wire sizes (75ºC copper) for all models, including the most commonly used heater sizes. Also shown are the number of field power circuits required for the various models with heaters. The unit rating plate lists a “Maximum Time Delay Relay Fuse” or “HACR Type” circuit breaker that is to be used with the equipment.
FIGURE 3 MOUNTING INSTRUCTIONS 4 9/ 16 MIS-311 NOTE: It is recommended that a bead of silicone caulking be placed behind the side mounting flanges and under the top flashing at the time of installation. FIGURE 4 ELECTRIC HEAT CLEARANCE WARNING 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.

START UP IMPORTANT INSTALLER NOTE COMPRESSOR CONTROL MODULE For improved start-up performance, wash the indoor coil with a dishwasher detergent. The compressor control module is optional on the models covered by this manual. The compressor control is an anti-short cycle/lockout timer with high and low pressure switch monitoring and alarm relay output. CRANKCASE HEATERS All units are provided with some form of compressor crankcase heat.
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 Shown in the drawing below are the correct fan blade setting dimensions for proper air delivery across the outdoor coil. 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.
