Checking Up the Sub Power Supply
Final Checks & User Tips
The sub power supply is a device to prevent electric leakage due to the over current.
Install the sub power supply separately near the ventilator and turn it off when you
clean the ventilator or you do not use the ventilator for a long period of time.

Turn on the sub power supply which is installed separately.
- The sub power supply is not supplied with the ventilator.
Purchase the sub power supply individually.
 If the circuit breaker (MCCB, ELB) is installed, the sub power supply does
not need to be installed mandatorily.
Recommended Operation Condition
 Install and operate the ventilator in between -15°C and 40°C. If the
ventilator is operated under the condition other than are indicated,
it may not operate due to the protective device in the ventilator.
Especially, if outside temperature is under -15°C, the ventilator does not
operate at all.
 Do not operate the ventilator when typhoon comes. Water may get in the
room through the ventilator due to the rain and heavy winds.
 Avoid operating the ventilator 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.
