source
•
Use an ELB (Earth Leakage Breaker). If not used, it will
cause an electric shock or a fire.
•
Do not operate the system until all the check points have
been cleared:
-
Check to ensure that the electrical resistance is more
than 1 megohm, by measuring the resistance between
ground and the terminal of the electrical parts. If it is
less than 1 megohm, do not operate the system until the
electrical leakage is found and repaired.
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 crankcase heater.
•
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 90ºC.

•
Follow the local codes and regulations when selecting field wires.
•
The wire sizes in the table are selected at the maximum current of the
unit according to the European Standard, IEC 60335-1. Use the wires
which are not lighter than the ordinary tough rubber sheathed flexible
cord (code designation H05RN-F) or ordinary polychloroprene
sheathed flexible cord (code designation H05RN-F).
•
Use a shielded cable for the transmitting circuit and connect it to
ground.
