Terminal
Dryer
(1000W)
Heat the left side of the
terminal for a period of
approximately 15 minutes.
Check on refrigerant piping /
insulation materials
Check airtight test and vacuum
drying.
Check the below items.
2Power wiring
2Control transmission wiring
between units
2Earth 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)
2 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 res
istance.
Heat the compressor as shown on
the right and then recheck the
insulation.
Is the pipe size proper?
Are the design pressures for the liquid pipe, suction pipe, dual
pressure gas pipe, and pressure equalizer pipe (in case of multi
units) all not less than 4.0 MPa?
Is the pipe insulation material installed securely?
Liquid, suction and high & low pressure gas pipe need to b
e
insulated. (Otherwise causes water leak.)
Have the airtight test and the vacuum drying been conducted
according to the procedure in the Installation Manual?
