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
1.1.2 Turn Power On
(V3180)
Check on amount of refrigerant
charge
Check on refrigerant piping
Check the below items.
2
Power wiring
2
Control transmission wiring
between units
2
Earth wire
Is the power supply three-phase 380-415V / 50Hz?
Have you finished a ductwork to drain?
Have you detach transport fitting?
Is the wiring performed as specified?
Are the designated wires used?
Is the grounding work completed?
Use a 500V megger tester to measure the insulation.
2
Do not use a megger tester for other circuits than 380-415V circuit.
Are the setscrews of wiring not loose?
Is the electrical component box covered with an insulation cover
completely?
Is pipe size proper? (The design pressure of this product is
4.0MPa.)
Are pipe insulation materials installed securely?
Liquid and gas pipes need to be insulated. (Otherwise causes
water leak.)
Are respective stop valves on liquid and gas line securely open?
Is refrigerant charged up to the specified amount?
If insufficient, charge the refrigerant from the service port of stop
valve on the liquid side with outdoor unit in stop mode after turning
power on.
Has the amount of refrigerant charge been recorded on “Record
Chart of Additional Refrigerant Charge Amount”?
(V3056)
"
Be sure to turn the power on 6 hours before starting operation to
protect compressors.
"
Close outside panels of the outdoor unit.
Turn outdoor unit power on.
Turn indoor unit power on.
Carry out field setting on
outdoor PC board
