(Clean filters once or twice per year.)
1 Using a cross-head screwdriver, remove the screw.
2 Enter the roof space through the energy recovery
ventilator inspection opening. While holding the in-
spection cover in one hand, rotate two knobs to ad-
just their orientations as shown in the figure at right.
Open the inspection cover by about 90 degrees, lift it
up slightly and remove it from the hook.
3 A filter is installed in each of two positions. Pull it
forward to remove it.
4 Softly tap the removed filter using one hand, or use
the cleaner to remove dust and dirt. If the filter is
highly contaminated, wash it with the solution of
lukewarm water and neutral detergent.
5 Dry the filter suffciently, and then install it.
Never use open flame to dry the filter. Doing so
may cause deformation or otherwise alter the
filter.
If a filter is broken, contact your sales representative
■
or installation service shop.
