Replacing the fan

The fan in the unit has an expected lifespan of approximately 5 years.
Replace it when the Error Lamp is lit and the fan is stopped.
When this product is used in compliance with UL standards or CE marking, do
not replace the fan.
● Fan replacement does not comply with UL, CE standards or CE marking.
The fan can be replaced while the unit is in operation (power supply is being output) or while the
unit is stopped (power supply output is stopped). Choose whichever replacement method is more
convenient.
* If the fan stops or is removed while the unit is in operation, the "EF" lamp blinks, the beep sounds con-
tinuously, and output is supplied through bypass operation.
In this state, if an input power supply error occurs due to a power failure or other reason, the unit stops
without entering Battery Mode.
* Do not replace the fan while in Battery Mode.
The unit will stop.

Do not insert your hand or metal objects into the fan recess.
• Doing so may cause electric shock or short-circuit.
Do not put your fi ngers into the fan.
• The fan spins when the AC input plug is connected to a wall outlet (commercial power).
• Doing so may result in injury.
Detect abnormally working fans.
(Not rotating, abnormal noise, vibrating, the fan contacting the cover, etc)
