Dealer Filter Change Instructions - 2500HV, 4000HV & 6000V
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 screw(s) from HEPA filter access panel.
b. For 2500HV or 4000HV, unlatch the three retaining
clips and lift off HEPA filter access panel.
For 6000V, pull the HEPA filter access panel up by
the finger tabs and lift out to remove.
c. Bracing the unit so it does not move, turn the
HEPA cartridge counter-clockwise and lift/pull out.
2. Pre-filter Replacement
a. Pull the pre-filter up and off the unit.
NOTE: The pre-filter may contain contaminants,
remove it slowly to avoid releasing particles back
into the air.
b. Foam pre-filters can be washed several times,
wash by hand in warm water. Let it dry completely
before placing it back onto the HEPA cartridge.
b. If replacing the filter, remove plastic shrink wrap
from the new pre-filter.
c. Stretch the new/washed filter around the top of the
HEPA cartridge and slide it down into place
3. Inner Carbon Filter Replacement
a. Look inside the HEPA cartridge to locate the two
ends of the inner carbon filter.
b. Pull one end of the old inner carbon filter in and
bend it into a loose roll so it can be removed.
c. Remove the inner carbon filter from the HEPA cartridge.
d. Remove plastic shrink wrap from the new inner
carbon filter.
e. Unroll the inner carbon filter and roll it up in the
opposite direction (this makes the filter follow a
more contoured profile against the inner HEPA fil-
ter surfaces and helps keep it in place), place the
rolled inner carbon filter inside the HEPA car-
tridge and gently unroll it until the ends ‘butt’
together and the filter is snug against the HEPA
filter.
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.
b. With each annual filter replacement kit, a new ‘o’
ring is provided. The old one is removed by pinch-
ing it between two fingers and pulling it off the col-
lar on the blower deck.
c. Discard old ‘o’ ring.
d. Place the new ‘o’ ring onto the collar and slide it
down to the base of the blower deck.
5. Optional Carbon Canister
a. Remove old carbon canister (if installed) by pulling
it out from the inside of the HEPA filter.
b. If replacing an inner carbon filter with the carbon
canister, remove inner carbon filter by following
the steps a. to c. in section 3.
c. Remove the plastic shrink wrap from the new car-
bon canister.
d. Slide the carbon canister into the HEPA cartridge,
smaller end first. The carbon canister should slide
all the way in until the metal edges at the base
meet the HEPA filter.
e. Support the carbon canister with your fingers so it
does not slide out when replacing the HEPA car-
tridge assembly into the unit.
7. Installing the HEPA Filter Cartridge
a. With the filters changed or inspected, all 3 filters
are ready to be placed back into the unit. Place
the HEPA cartridge gently into the unit (if a carbon
canister is being used, take care not to let it slide
out as it is heavy and could damage the unit)
b. When the HEPA cartridge is in place, brace the unit,
press down and gently turn it clockwise to lock it into
place. If too much force is used, the cartridge may be
difficult to remove!
c. Replace the HEPA filter access panel.
For 4000HV, latch it with the three retaining clips.
d. Re-install safety screw(s) into HEPA filter access panel.
e. Plug the unit back into a power outflow and turn it
on.
