1. Precautions
11) Cut off the power.
● Make sure to cut off the power before repair. If not, you may
be damaged by an electric shock.
12) Do not install an outdoor unit on the apartment outside
wall(or equivalent) for safety.
● Installing an outdoor unit on the apartment outside wall(or
equivalent) is prohibited for the safety purpose. Service will
not be available for the outdoor unit where our servicemen
can not access and the cost of moving the outdoor unit to
the service area will be borne by the customer.
● If requested by the customer, you shall discourage him to
install an outdoor unit on the apartment outside wall(or
equivalent).
13) Keep the drain hose outlet free.
● Otherwise, air flow will get slow, which may hinder cooling
capacity.
● Also, dew may be laden on the service valve.
14) Use of Certified Parts
● Use certified parts only. (An electric contact part, if broken
down, shall not be repaired but replaced with a new one.
Remodeling shall be prohibited. In no case, the customer
shall repair the product on his own because this is danger-
ous enough to bring about breakdown or fire.)
15) Ban on Middle Connection of Power Cord
● Do not cut the power cord in the middle to be connected to
other power cord nor use a middle socket between two
power cords. This is dangerous enough to bring about
breakdown or fire.
16) Check Insulation
● After assembly, be sure to check insulation resistance.
(Use an insulation ohmmeter to measure the insulation
resistance between the power cord and the earthing wire.
Do not supply power until it reads 30MΩ.)
17) Be sure to keep the symmetry of the product.
● Otherwise, you may hear vibration noise.
18) Caution for Children
● Keep children off the product while it is in repair.
Otherwise, they might be endangered.
19) Be sure to put the indoor or outdoor unit free of corrosive
gases such as sulfuric water, ammonium and sulfuric
gas.
● Otherwise, copper tubes or soldered parts could be
corroded causing refrigerant leak.
10) Arrangement of surroundings
● After repair finishes, clean the air conditioner and its
surroundings and inform the customer of what it is like.
