If the installation is not perfectly done, it can cause water leak, 

  electric shock, or fire.  Ask your dealer or qualified person.

Before electric wiring

CAUTION

The wiring must be securely done by using proper cable. The wires should 
be connected to the terminals not to have external force of the cable.

Unperfect connections can cause heat or fire.

The termial cover (panel) of the unit must be installed securely.

Unperfect installation can cause fire or electric shock by dust or water.

The electric installation must be done by qualified person in accordance 
with this installation manual.  Use the separate circuit only for this machine 
and use rated voltage and circuit breaker.

If the electric circuit power is not sufficient or the wiring is not 

  properly done, it can cause electric shock or fire.

Without a circuit breaker, it can cause electric shock.

Install a circuit breaker depending upon the location.

Use standard wires which meet current capacity.

Otherwise, it can cause short-circuit, heat, or fire.

Wires must not have tension.

It can cause snipping, heat, or fire.

Put ground wire.

Never ground to gas pipe, water pipe, lightning conductor, or 

  telephone ground wire.  
  Unperfrect ground can cause short-circuit.

Use proper fuses

If you use larger size fuses or neelde wire, it can cause failure or fire.

Before test operation

Turn the power on 12 hours or more before operation.

If you start operation as soon as the power on, it can cause failure.  

  Never turn the power off during season.

Never operate the machine without panel or guard off.

It can cause serious injury being caught by rotating part or burn or 

  electric shock by high voltage part.

Never operate the machine without air filter off.

It can cause failure by dust.

Never operate the switches with your hand wet.

It can cause electric shock.

Never touch refrigerant pipes while the machine running.
