Is the earth leakage circuit breaker
2
(all-pole switching function provided)
installed?
Is there any wrong installation of optional

parts or wrong wiring?
4
Was the ground wire work performed?
Are there any wrong power supply wiring,
Tubing
5
wrong connection wire, wrong signal wire
&
or loose screw?
Wiring
Is the thickness of wire in accordance
6
with rule?
Is the power-supply voltage equal to the
7
nameplate of the unit?
Was the check of the airtight test, flared
8
tube fitting and gas leakage on the
welded portion performed?
Has the adhesive been applied to the
9
drain connecting portion (resin portion) of
the indoor unit?
Drain
10 Is there water leakage?
Check

gradient (1/100 or more) by rule. Is the
drain water flowing smoothly?
Was the heat insulation work at a suitable
Heat
location including the flared tube fitting

□
Check
Possibility of Failure & Checkpoint
□
There is a possibility of light injure or loss of
property.
□
□
□
Power failure or short circuit may cause electric
shock or fire. Check installation work and ground
□
wire work.
□
□
If the gas leakage occurs, the unit quality not only
□
becomes inferior but affects environment. Repair it
as quickly as possible.
□
The resin portion cracks after a few months and it
may cause water drain.
□
Since there is a possibility of water drain, repair the
□
drain pipe if the drain failure or water drain occurs.
The quality of unit not only becomes inferior but
□
there is a possibility of the water drain. So, perform
the heat insulation work properly.
The discharge temperature decreases in cooling
□
mode according to the reduction of air volume
and there is a possibility of dew drops. Be sure to
change settings.
□
Check if there is a fan contact or distortion of the
indoor unit.
Check if the unit does not operate or there is a
□
wrong tubing or wiring connection with another
system.
