Test Operation
1.1
Procedure and Outline
Follow the following procedure to conduct the initial test operation after installation.
1.1.1 Check Work Prior to Turn Power Supply On
Check on refrigerant piping /
insulation materials.
Check airtight test and vacuum
drying.
Check on amount of refrigerant
charge.
Check the stop valves for
conditions.
Terminal
Dryer
(1000W)
Check the below items.

Power wiring
2
Control transmission wiring

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)
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 resistance.
Heat the compressor as shown on
the right and then recheck the
insulation.
¡
Is the pipe size proper?
¡
Is the pipe insulation material installed securely?
Liquid and gas pipes need to be insulated. (Otherwise causes
water leak.)
¡
Have the airtight test and the vacuum drying been conducted
according to the procedure in the Installation Manual?
¡
Has a proper amount of refrigerant been charged according to the
result of the "Calculation of the refrigerant additional charging
amount"?
Charge refrigerant in the liquid state from the service port of the
liquid-side stop valve, with stopping the outdoor unit after the
completion of vacuuming.
If the total amount of refrigerant calculated cannot be charged,
follow information in "Additional charging of refrigerant" on the
following page to charge the refrigerant by the deficient amount.
¡
Has the refrigerant additional charging amount been recorded on
the "Service Precautions" label?
¡
Check to be sure the stop valves are under the following
conditions.
Liquid-side stop valve
Open
Gas-side stop valve
Open
