Once the repair work has been completed, check for refrigerant leaks, and check the insulation

 

resistance and water drainage.

 

Then perform a trial run to check that the air conditioner is running properly.

reinstallation

 

 

When carrying out the pump-down work shut down the compressor before disconnecting the

 

 

refrigerant pipe.

 

Disconnecting the refrigerant pipe with the service valve left open and the compressor still

 

operating will cause air, etc. to be sucked in, raising the pressure inside the refrigeration cycle to

 

an abnormally high level, and possibly resulting in reputing, injury, etc.

 

 

 

When the service panel of the outdoor unit is to be opened in order for the compressor or the

 

area around this part to be repaired immediately after the air conditioner has been shut down, set

 

the circuit breaker to the OFF position, and then wait at least 10 minutes before opening the

 

service panel.

 

If you fail to heed this warning, you will run the risk of burning yourself because the compressor

 

pipes and other parts will be very hot to the touch. In addition, before proceeding with the repair

 

work, wear the kind of insulated heat-resistant gloves designed to protect electricians.

Only a qualified installer (1) or qualified service person (1) is allowed to install the air

 

conditioner. If the air conditioner is installed by an unqualified individual, a fire, electric shocks,

 

injury, water leakage, noise and/or vibration may result.

 

 

 

Before starting to install the air conditioner, read carefully through the Installation Manual, and

 

follow its instructions to install the air conditioner.

 

 

 

Do not install the air conditioner in a location that may be subject to a risk of expire to a

 

combustible gas.

 

If a combustible gas leaks and becomes concentrated around the unit, a fire may occur.

 

 

Installation

Install the indoor unit at least 2.5 m above the floor level since otherwise the users may injure

themselves or receive electric shocks if they poke their fingers or other objects into the indoor unit

 

while the air conditioner is running.

 

 

 

Install a circuit breaker that meets the specifications in the installation manual and the stipulations

 

in the local regulations and laws.

 

 

 

Install the circuit breaker where it can be easily accessed by the qualified service person (1).

 

 

 

Do not place any combustion appliance in a place where it is directly exposed to the wind of air

 

conditioner, otherwise it may cause imperfect combustion.
