Test Operation
Operations which require the
power to be turned ON.
Check the below items.
Power wiring
Control transmission wiring
between units
Earth wire
{ Is the wiring performed as specified?
{ Is the designated wire used?
{ Is the wiring screw of wiring not loose?
{ Is the grounding work completed?
{ Is the insulation of the main power supply circuit deteriorated?
Use a 500V megger tester to measure the insulation. (1)
• Do not use a megger tester for other circuits than 200V (or
240V) circuit.
1: Measure to be taken against decreased insulation resistance in
the compressor
If the compressor is left to stand for
an extended period of time after the
refrigerant charge with the stop valve
open and the power supply OFF, the
refrigerant may be mixed in the
compressor, thus decreasing the
insulation resistance.
Heat the compressor as shown on
the right and then recheck the
insulation.
Dryer
(1000W)
Terminal
5cm
Heat the left side of the
terminal for a period of
approximately 15 minutes.
