Electrical Installation
!
WARNING
• Use an ELB (Electric Leakage Breaker). If not used, it will cause electric shock or fire.
•
Do not operate the system until all the checkpoints have been cleared.
a
Ensure that the insulation resistance is more than 2MΩ, 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
Ensure that the stop valves of the outdoor unit are fully opened and then start the system.
