Horizontal/Side Discharge Condensing Units

1) Install according to this installation instructions strictly. If installation is defective, it will cause water

leakage, electrical shock fire, and may void the warranty.

 

 

 

.

2) Use the manufacturer’s specified and supplied parts only

3) Install in a strong and firm location which is able to withstand the unit’s weight. If the strength is

insufficient or installation is not properly done, the units can fall and cause injury.

4) For electrical work, follow all local and National electrical codes  and these installation instructions.

An independent circuit and single outlet must be used. If electrical circuit capacity is not enough or a

 

 

 

 

 

 

   

   

 

 

   

 

 

defect found in electrical work, it may cause electrical shock or fire.

 

   

 

 

 

 

5) Use the specified cable, connect tightly and clamp the cable so that no external force will be acted

on the terminal. If connection is loose, it may cause excessive heat build up.

 

 

   

 

   

 

 

6) Wiring routing must be properly arranged so that control board cover is fixed properly. If control board

cover is not fixed perfectly, it will cause heat build up at connection point of terminal, fire or electrical shock.

     

 

     

 

   

 

   

     

 

7) When carrying out piping connection, take care not to let air substances other than the specified

refrigerant go into refrigeration circuit. Otherwise, it will cause lower capacity, abnormal high pressure

   

 

 

 

   

 

 

 

 

 

 

in the refrigeration cycle, explosion and injury.

 

 

 

 

 

 

8) Do not modify the length of the power supply cord or use an extension cord, and do not share the

single outlet with other electrical appliances. Otherwise, it may cause fire or electrical shock.

 

 

 

 

 

 

 

 

   

 

1) This equipment must be properly grounded and installed with and ground leakage current breaker,

 electrical shock.

otherwise it may cause

2) Do not install the unit in place where leakage of flammable gas may occur. If gas leaks and

accumulates near or surroundings the unit, it may cause fire.

3) Carry out drainage piping as mentioned in installation instructions. If drainage is not properly done,

water may enter the room and damage the furniture.

  The seriousness of safety precautions is classified by the following indications:

This symbol indicates the possibility of death or serious injury.

This symbol indicates the possibility of injury or damage to property.
