6.1.2 Installation Fan Replacement
The moisture resistant gasket protects the PS-A and improves its water resistance. For instructions on install-
ing the PS-A’s gasket.
6.2 Cleaning the Fan Filter
Since excessive dirt and dust in the filter of the PS-A’s electric fan can potentially affect the performance of
the unit, regular inspection and cleaning of the filter is strongly recommended.
(1) Remove the fan cover with pressing in
on both fan cover clips.
(2) Remove the filter from the fan cover.
(3) Clean the filter completely.
If stubborn dirt or stains are present,
wash the filter with a neutral detergent.
(4) After reattaching the filter to the filter cover, reattach the fan cover with its cover attachment screw.

2.2.2 Installation Procedures (page2-12)
• A gasket which has been used for a long period of time may have scratches or
dirt on it, and could have lost much of its water resistance. Be sure to change the
gasket periodically (or when scratches or dirt become visible).
• Do not wring the filter to dry it.
• When drying the filter, dry it without exposing it to direct sunlight.
• Allow it to air dry completely before reattaching to the PS-A.
• Be sure the fan cover is securely attached to the PS-A unit. This is to ensure the
fan cover does not fall of while the PS-A unit is operating.
