SHIPPING DAMAGE DUCT WORK 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. All duct work, supply and return, must be properly sized for the design air flow requirement of the equipment. Air Conditioning Contractors of America (ACCA) is an excellent guide to proper sizing.
FILTERS A 1 inch throwaway filter is supplied with each unit. The filter slides into position making it easy to service. This filter can be serviced from the outside by removing the service door. A 1 inch washable filter and 2 inch pleated filter are also available as optional accessories. The internal filter brackets are adjustable to accommodate the 2 inch filter by bending down the tabs to allow spacing for the 2 inch filters.
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. See Figures 5 and 6. WARNING Fire hazard can result if 1/4 inch clearance to combustible materials for supply air duct is not maintained. See Figure 3. 3.
The disconnect access door on this unit may be locked to prevent unauthorized access to the disconnect. To convert for the locking capability, bend the tab located in the bottom left hand corner of the disconnect opening under the disconnect access panel straight out. This tab will now line up with the slot in the door. When shut, a padlock may be placed through the hole in the tab preventing entry. See Start-up section for information on three phase scroll compressor start-ups.

START UP IMPORTANT INSTALLER NOTE HIGH PRESSURE SWITCH For improved start-up performance, wash the indoor coil with a dishwasher detergent. The WA701 and WA721 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. CRANKCASE HEATERS WL701 units are provided with compressor crankcase heat.
SERVICE HINTS 1. Caution homeowner to maintain clean air filters at all times. Also, not to needlessly close off supply and return air registers. This reduces air flow through the system, which shortens equipment service life as well as increasing operating costs. 2. Check all power fuses or circuit breakers to be sure they are the correct rating. 3. Periodic cleaning of the outdoor coil to permit full and unrestricted airflow circulation is essential.
ADJUSTMENTS PHASE MONITOR Adjustable Delay on Make and Delay on Break Timer All units with three phase scroll compressors are equipped with a 3 phase line monitor to prevent compressor damage due to phase reversal. The potentiometer is used to select Delay on Break time from 30 seconds to 5 minutes. Delay on Make (DOM) timing on power-up and after power interruptions is equal to 2 minutes plus 10% of Delay on Break (DOB) setting: 0.5 minute (30 seconds) 1.0 minute (60 seconds) 2.
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.
