You should connect the power cable into the power cable terminal and fasten it
with clamp.
The unbalanced power must be maintained within 2% of supply rating.
- If the power is unbalanced greatly, it may shorten the life of the condenser. If the
unbalanced power is exceeded over 4% of supply rating, the indoor unit is protect
ed, stopped and the error mode indicates.
To protect the product from water and possible shock, you should keep the power
cable and the connection core of the indoor and outdoor units in the iron pipe.
Connet the power cable to the auxiliary circuit breaker.
An all pole disconnection from the power supply must be incorporated in the fi xed
