3. Maintenance of the Cooler Unit (Option)
WARNING
■ Be sure to refer to the operation manual attached to the FA cooler ENC-G series.
■ Turn OFF the power supply during inspection or cleaning. Otherwise, that can
cause electric leaks and injury.
■ Do not water the cooler unit directly or clean it with water. Otherwise, that can
cause electric leaks and malfunction.
■ When you open the panel for inspection or cleaning, return the panel after the
work. If the cooler unit is operated with the panel open or removed, you may touch
the inside of the device and that can cause electric leaks and injury.
Cleaning and Replacing the Filter
The lter has a function to remove dust and dirt in the air. If the lter is clogged with
dust, the cooler unit is hard to cool the equipment, thereby causing temperature error.
Rinse dust and oil mist attached to the lter every day with aqueous solution mixing
neutral detergent and the hot water in a ratio of 1:19.
If the lter is heavily contaminated, purchase separately sold lters (ENC-F-38) to re-
place them.
For the replacement procedure, refer to the operation manual attached to the FA
cooler ENC-G series.
Replacing the FAN Motor
For the replacement procedure, refer to the operation manual attached to the FA
