•
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 60245 IEC 57) or ordinary polychloroprene
sheathed flexible cord (code designation 60245 IEC 57).
• Use a shielded cable for the transmitting circuit and connect it to
ground.
• In the case that power cables are connected in series, add maximum
current to each unit and select wires below.

Before setting dips switches, firstly turn off power source and set the
position of the dips switches. If the switches are set without turning off the
power source, the contents of the setting are invalid.
