4.UNIT INSPECTION This product has been inspected at the factory and released to the transportation agency without known damage. Inspect exterior of carton for evidence of rough handling in shipment. Unpack carefully. If damage is found, report immediately to the transportation agency. 5.EQUIPMENT PROTECTION FROM ENVIRONMENT The metal parts of the unit may be subject to rust or corrosion in adverse environmental conditions. This oxidation could shorten the unit life.
Provide a level concrete slab. To prevent transmission of noise or vibration, slab should not be connected to building structure. Some sort of sound-absorbing material should be placed between the condenser and the slab. A good material to use is rubber and cork pad. For rooftop application, make sure the building construction can support the weight and that proper consideration is given to the weather-tight integrity of the roof. The condensing unit contains moving parts and can vibrate.

1.Tubing should be cut square. Make sure it is round and free of burrs at the connecting ends. Clean the tubing to prevent contamination from entering the system. 2.Make sure that both refrigerant stop valves at the outdoor unit are closed. 3.Push the tubing into the fitting until it stops. This prevents flux from getting into the system. 4.Remove the cap and Schrader valve core from the service port to protect the valve seals. 5.Wrap a wet rag around the valve stub before brazing. 6.
1.Fully open both shutoff valves. System Superheat 2.Connect service gage manifold to the valve service Ambient Return Air Temperature ( F) ports, being sure to evacuate lines.

The condensing unit rating plate and the tables of "Physical and Electrical Specifications / Outdoor Units" (Table 1 and 2) provide pertinent data necessary for the selection of proper size electrical service and over-current protection devices. Table 9 provides data on the minimum copper wire size as a function of supply wire length and circuit ampacity.
8.OPERATION Most single phase units are operated without start relay or start capacitor. Such systems should be off for a minimum of 5 minutes before restarting to allow equalization of pressures. The thermostat should not be moved to cycle unit without waiting 5 minutes. To do so may cause the compressor to stop on an automatic open overload device or blow a fuse. Poor electrical service can cause nuisance tripping in overloads or blow fuses. The compressor has an internal overload protector.
Symptom Possible Cause Power off or loose electrical connection Incorrect thermostat setting No cooling Defective contactor Open circuit breaker of blown fuses Defective transformer Interconnecting low voltage wiring damage Dirty filters Indoor air blockage Blocked outdoor coil Improperly sized unit Insufficient Cooling Improper airflow Incorrect refrigerant charge Air, non-condensibles or moisture in system Incorrect voltage Water on floor or in furnace Blocked condensate drain and "P" trap Run or start c
