• 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.
