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 protected, stopped and the error mode indicates.
•
To protect the product from water and possible shock, you should keep the power cable and the connection
cord of the indoor and outdoor units within ducts. (with appropriate IP rating and material selection for your
