(other than those authorized by the manufacturer) into, onto, or in conjunction with the air conditioner. You should be aware that the use of unauthorized components, accessories or devices may adversely affect the operation of the air conditioner and may also endanger life and property.
9.3.Wiring diagram ----------------------------------------------------------------------------- 1.INTRODUCTION This manual contains the installation and operating instructions for your new air conditioner. Improper installation can result in unsatisfactory operation or dangerous conditions. Carefully read this manual and any instructions packaged with separate equipment required to make up the system prior to installation.

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.
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.
PITCH SUCTION LINE TOWARD OUTDOOR UNIT 1/2" FRO EVERY 10' OF LINE OUTDOOR UNIT LIQUID LINE INVERTED LOOP LIQUID LINE INDOOR UNIT OUTDOOR UNIT SUCTION LINE Only refrigeration-grade copper piping (dehydrated and sealed) should be used. Take extreme care to keep the refrigerant tubing clean and dry prior to and during installation.
Refrigerant Line Sizing Check the following table (Table 7) for correct suction and liquid line sizes for any combination of the unit size and the maximum refrigerant line length. Unit Size 0 - 24 (Ton) Suction The factory charge is sufficient for 25 feet of standard liquid line. For longer or shorter liquid line lengths, adjust the charge as follows: 1/4"...
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.
1.Fully open both shutoff valves. 2.Connect service gage manifold to the valve service ports, being sure to evacuate lines. 3.Startup the system (Refer to the Section 7 - "System Startup"). Run system at least 10 minutes to allo pressure to stabilize. 4.Temporarily install thermometer on suction (large) line near condensing unit.
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.
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 Replace thermostat wiring Dirty filters Indoor air blockage Blocked outdoor coil Improperly sized unit Insufficient Cooling Improper airflow Incorrect refrigerant charge...
