Note: For some indoor units
●
Use an ELB (Electric Leakage Breaker).
●
Do not operate the system until all the check points have been cleared.
(A)
Check to ensure that the insulation resistance is more than 2 Mega Ohm, 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.
(B)
Check to ensure that the stop valves of the outdoor unit are fully opened and then start the
system.
