• 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 not, do not operate the system
until the electrical leakage is found and repaired.
• Do not touch any of the parts at the discharge gas side by hand
while the system is running, since the compressor chamber and
the pipes at the discharge side are heated higher than 90ºC.
19.1 BEFORE TEST RUN
Recheck that there is not any problems to the installation, and
do not perform the test run until all the following checking points
have been cleared.
1 Check to ensure that the refrigerant piping and the transition
wiring are connected to the same refrigerant cycle system.
If not, it will cause an abnormal operation and breakage of
instruments.

the phase of power source. If incorrectly connected, the unit
will not operate and the remote control switch will indicate
the alarm code "05". In this case, check the phase of the
primary power source according to the attached attention
label on the rear side of the service cover. Then, perform
the reconnection work correctly with turning OFF the power
supply.
4 Check to ensure that the main power source has been
turned ON for more than 12 hours, to warm the compressor
