Power wiring figure
Indoor and outdoor use their individual power source. All indoors use one power source. Must
install the leakage breaker and the over current breaker, or electric shock will occur.
a. Power cable model:
YCV080: H05RN-F; B-YCV150;YCV180: H07RN-F
b. The diameter of earth cable cannot be smaller than power cable's.
c. Power cable must be fixed firmly.
d. Each outdoor must be earthed well.
e. When power cable exceeds the range, thicken it appropriately.
f. The temperature of refrigerant circuit will be high, please keep the power cable away from the
copper tube.
g. An all-pole disconnection switch having a contact separation of at least 3mm in all poles
should be connected in fixed wiring.
