Do not operate the system until all the check points have
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
