lnstallation and Maintenance
7. Electrical lnstallation
• Use an ELB (Electric Leakage Breaker). lf not used, it may cause an electric shock or a tire.
• 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 MO, by measuring the resistance between
ground and the terminal of the electrical parts. lf 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.

NOTES:
1) Follow local codes and regulations when selecting field wires.
2) The wire sizes marked in the table are selected at the maximum current of the unit according to the
European Standard, EN60335-1. Use the wires which are not lighter than the ordinary polychloroprene
sheathed flexible cord (code designation H07RN-F).
When connecting the terminal block using flexible cord, make sure to use the round crimp-style terminal
for connection to the power supply terminal block.
Place the round crimp-style terminals on the wires up to the covered
part and secure in place.
