Pre-filter access

Cleaning the Fan Filter Unit Pre-filter

(when applicable)

WARNING!

Disconnect the unit from the electrical power source before attempting to service the unit.

Note:  For maximum performance, wash pre-filter every three to six months at a minimum.

Step 1 --  Turn the unit off with the rocker switch located on the unit.

Step 2 --  Disconnect the unit at the power source or at the service panel in

accordance with OSHA (LOTO) practices and procedures.

Step 3 --  Using a driver, remove the screw holding the hinged door.  This

allows access to the pre-filter.  Slide the pre-filter out of the motor

enclosure. This step is not applicable if unit is non-ducted.

Step 4 --  Wash the filter with hot water and a mild detergent and rinse

thoroughly.  Do not use a caustic solution to clean the filter.  Blow

dry or let air dry and slide the filter back into the motor enclosure.  

Filter should be completely dry before reinstalling into unit.

  

Step 5 --  Using the driver, re-secure the cover with the screw.
