●
Is the open and close device / leakage breaker installed?
●
Is the power supply cable’s thickness and length appropriately measured as described in the
instructions?
●
Is it earthed (grounded)?
●
Check that the insulation resistant value is more than 1 M
Ω
.
Use the 500 V mega-testers to measure the insulation.
Do not use the mega-testers for any other circuit except for voltage of 220 V to 240 V.
●
Are the wire connections for the indoor/outdoor units connected as described in the
instructions? Are there any looped wires?
Refrigerant pipe
●
Is the piping installed as described in the instructions?
●
Are the pipes sizes appropriate?
●
Does the pipe’s length adhere to the specifications?
●
Is the branch pipe slant being appropriately done as described in the instructions?
●
Was vacuum removal sufficiently carried out?
●
Was the leak tightness test carried out with nitrogen gas? Use the testing pressure of 4.15
MPa.
●
Is the piping insulation material appropriately installed? Insulation material is necessary for
both gas and liquid piping.
●
Is the 3-way valve for the liquid side and gas side open?
Filling additional refrigerant
●
This product is charge-free. No additional refrigerant is necessary.
Other
●
Does the indoor unit’s connection capacity fall within the range of 50 to 130%?
●
Check that the refrigerant piping and the related wiring is connected to the same refrigerant
system.
