Checking Up the Sub Power Supply
The sub power supply is a device to prevent electric leakage due to the over current.
Install the sub power supply separately near the unit and turn it off when you clean the
unit or you do not use the unit for a long period of time.
Install & Operation Ranges
•
If the circuit breaker (MCCB, ELB) is installed, the sub power supply does not need to be installed mandatorily.
•
If the unit is operated under the condition other than are indicated, it may not operate due to the protective device
in the unit. Especially, if outside temperature is under -15°C, the unit does not operate at all.
• Do not operate the unit when typhoon comes. Water may get in the room through the unit due to the rain and
heavy winds.
• Avoid operating the unit in indoor or outdoor with high temperature and humidity since dew may form on the
internal part of the product, including the heat exchanger. Especially avoid using it during the long rainy period in
the summer.
