Healthy Climate® Dealer Filter Change Instructions
It is recommended that gloves and a filtered
breathing mask be worn during filter replacement
to avoid breathing particulates (dust, mold, pollen,
etc.) captured on the filter that become airborne
during the filter(s) changeout.
The old filters should be wrapped and sealed in
plastic bags immediately upon removal from the
unit to avoid distributing particles throughout the
house during the process of disposal.
1. Accessing the filters
a. Remove safety screws from HEPA filter access
panel.
b. Unlatch the four retaining clips and lift off HEPA
filter access panel.
c. Bracing the unit so it does not move, turn the
HEPA cartridge counter-clockwise and lift out.
2. Carbon Pre-Filter Replacement
a. Locate the clips holding the carbon pre-filter in place.
Remove them and pull the carbon pre-filter off.
NOTE: The carbon pre-filter may contain
contaminants, remove it slowly to avoid releasing
particles back into the air.
b. Remove plastic shrink wrap from the new carbon
pre-filter.
c. Wrap the new carbon pre-filter around the HEPA
filter, making sure that the ends overlap.
d. Hook one end of the clip onto the overlapping
section of carbon pre-filter as shown in figure 13.
e. Press down on the hooked section while you pull it
across, stretching the carbon pre-filter tighter. as
shown in figure 14.
f. Push down on the other end of the clip once the
carbon pre-filter is stretched tight to lock the clip
into place as shown in figure 15. Release clip, it
should hold tight on both ends of the carbon pre-
filter keeping it together.
g. Repeat steps d through f with the other clips,
spacing them evenly on the carbon pre-filter to
give it even support.
3. Inner Charcoal Filter Replacement
a. Look inside the HEPA cartridge to locate the two
ends of the inner charcoal filter.
b. Pull one end of the old inner charcoal filter in and
bend it into a loose roll so it can be removed.
c. Remove the inner charcoal filter from the HEPA
cartridge.
d. Remove plastic shrink wrap from the new inner
charcoal filter.
e. Unroll the inner charcoal filter and roll it up in the
opposite direction (this makes the filter follow a
more contoured profile against the inner HEPA
filter surfaces and helps keep it in place), place
the rolled inner charcoal filter inside the HEPA
cartridge and gently unroll it until the ends ‘butt’
together and the filter is snug against the HEPA
filter mesh.
4. HEPA Filter Replacement
a. If replacing the HEPA filter with a new filter, discard
old HEPA filter and use new when replacing the
HEPA filter into the unit.
