Do not operate the system until all the check points have been cleared:
•
Check to ensure that the electrical resistance is more than 1 MΩ, by measuring the resistance between ground and the terminal of the electrical
parts. If not, do not operate the system until the electrical leakage is found and repaired. Do not impress the voltage on the terminals for transmis
-
sion 1 and 2.
•
Check to ensure that the stop valves of the outdoor unit are fully opened, and then start the system.
•
Check to ensure that the switch on the main power source has been ON for more than 12 hours, to warm the compressor oil by the oil heater
Pay attention to the following items while the system is running:
•
Do not touch any of the parts by hand at the discharge gas side, since the compressor chamber and the pipes at the discharge side are heated
higher than 90°C.
•
DO NOT PUSH THE BUTTON OF THE MAGNETIC SWITCH(ES), it will cause a serious accident.
•
Do not touch any electrical components for more than three minutes after turning OFF the main switch
•
Confirm that the gas line stop valve and the liquid line stop valve are fully open.
•
Confirm that the leakage of the refrigerant does not exist. The flare nuts are sometimes loosened by vibration during transportation.
•
Check that the refrigerant piping and the electrical wiring conform to the same system.
•
Confirm that the dip switch setting on the printed circuit board of the indoor units and the outdoor units are correct.
•
Check whether or not the electrical wiring of the indoor units and the outdoor units are connected as shown in the chapter
Electrical Wiring
