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. Refer to Table 9 for maximum static pressure available for duct design.
FRESH AIR INTAKE CONDENSATE DRAIN All units are built with fresh air inlet slots punched in the service panel. A plastic drain hose extends from the drain pan at the top of the unit down to the unit base. There are openings in the unit base for the drain hose to pass through. In the event the drain hose is connected to a drain system of some type, it must be an open or vented type system to assure proper drainage.
INSTALLATION INSTRUCTIONS WALL MOUNTING INFORMATION WIRING — MAIN POWER 1. These units are secured by wall mounting brackets which secure the unit to the outside wall surface at both sides. A bottom mounting bracket is provided for ease of installation, but is not required. 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.

START UP IMPORTANT INSTALLER NOTE For improved start-up performance, wash the indoor coil with a dishwasher detergent. CRANKCASE HEATERS All units are provided with some form of compressor crankcase heat. All single and three phase models have an insertion welltype heater located in the lower section of the compressor housing. This is a self-regulating type heater that draws only enough power to maintain the compressor at a safe temperature.
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 the drawing below are the correct fan blade setting dimensions 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 inches from compressor) as shown in Table 6.
