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.

Only a qualified installer (*1) or qualified service person (*1) is allowed to relocate the air conditioner. It

 

is dangerous for the air conditioner to be relocated by an unqualified individual since a fire, electric

 

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

 

 

 

Check the following items after reinstallation.

 

1) The earth wire is correctly connected.

 

2) The power cord is not caught in the product.

3) There is no inclination or unsteadiness and the installation is stable.

If check is not executed, a fire, an electric shock or an injury is caused.

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

 

heat-resistant gloves.

Cooling check

When the service panel of the outdoor unit is to be opened in order for the fan motor, reactor, inverter

or the areas around these parts 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 fan

 

motor, reactor, inverter heat sink and other parts will be very hot to the touch.

 

In addition, before proceeding with the repair work, wear the heat-resistant gloves.

 

 

 

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.

 

 

 

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

Installation

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 agent.

 

 

 

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.
