Toshiba RAV-HM1101FT-TR, Installation Manual

– 6 –

EN

• Under no circumstances, the power supply wire or the indoor and 

outdoor connecting wire must not be connected in the middle 

(Connection using a solderless terminal etc.) 

Connection trouble in the places where the wire is connected in the 

middle may give rise to smoking and/or a fire.

• Electrical wiring work shall be conducted according to law and 

regulation in the community and Installation Manual.

Failure to do so may result in electrocution or short circuit.

• Check that wiring will not be subject to wear, corrosion, excessive 

pressure, vibration, sharp edges or any other adverse environmental 

effects. The check shall also take into account the effects of aging or 

continual vibration from sources such as compressors or fans.

Test run

• Before operating the air conditioner after having completed the work, 

check that the electrical control box cover of the indoor unit and 

service panel of the outdoor unit are closed, and set the circuit 

breaker to the ON position. You may receive an electric shock if the 

power is turned on without first conducting these checks.

• If there is any kind of trouble (such as check code display has 

appeared, smell of burning, abnormal sounds, the air conditioner fails 

to cool or heat or water is leaking) has occurred in the air conditioner, 

do not touch the air conditioner yourself but set the circuit breaker to 

the OFF position, and contact a qualified service person. Take steps 

to ensure that the power will not be turned on (by marking “out of 

service” near the circuit breaker, for instance) until qualified service 

person arrives. Continuing to use the air conditioner in the trouble 

status may cause mechanical problems to escalate or result in 

electric shocks or other trouble.

• After the work has finished, use an insulation tester set (500 V 

Megger) to check the resistance is 1 M

Ω

 or more between the charge 

section and the non-charge metal section (Earth section). If the 

resistance value is low, a disaster such as a leak or electric shock is 

caused at user’s side.

• Upon completion of the installation work, check for refrigerant leaks 

and check the insulation resistance and water drainage. Then 

conduct a test run to check that the air conditioner is operating 

properly.

Explanations given to user

• Upon completion of the installation work, tell the user where the circuit 

breaker is located. If the user does not know where the circuit breaker 

is, he or she will not be able to turn it off in the event that trouble has 

occurred in the air conditioner.

• After the installation work, follow the Owner’s Manual to explain to the 

customer how to use and maintain the unit.

Relocation

• 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.

• 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 or other gas to be sucked in, raising the 

pressure inside the refrigeration cycle to an abnormally high level, 

and possibly resulting in rupture, injury or other trouble.

(*1) Refer to the “Definition of Qualified Installer or Qualified Service Person”.
