MAINTENANCE
Filter Inspection or Replacement:
Unplug the unit from the electrical
supply and allow the unit fan/motor to
stop rotating.
Use caution and established procedures
to avoid unnecessary release of
contaminants from the main housing,
access panel, Prefilters and HEPA
Cartridge during inspection or filter
replacement.
Dispose of used filters carefully using
appropriate procedures.
Foam sleeve and blanket type Prefilters
can be rolled inside out as they are
removed from service.
Stage 1 - Metal Mesh Prefilter (Option):
• Remove the Prefilter Holder from the
Inlet by pulling the handle upwards.
• The Metal Mesh Prefilter can be
cleaned by gently blowing out with
compressed air.
• Return the Prefilter Holder with the
Metal Mesh Prefilter to the frame on
the Inlet.
• It is recommended that the Metal
Mesh Prefilter be replaced regularly.
Stage 1 - Media Pad Prefilter (Option):
• Dispose and replace the Media
Pad Prefilter when it is covered in
particulate.
• Remove the Prefilter Holder from the
Inlet by pulling the handle upwards.
• Pull the used Prefilter from the
Holder and dispose appropriately.
• Fit the new Media Pad Prefilter into
the holder.
• Return the Prefilter Holder with the
Media Pad Prefilter to the frame on
the Inlet.
Stage 2 - Foam Filter:
• Follow directions for removing HEPA
Cartridge from the unit.
• Slowly pull the foam filter up and off
the HEPA Cartridge to avoid releasing
particles back into the air.
• Dispose appropriately.
• Pull the new Foam Filter over the
HEPA Cartridge (like a sock) and into
place.
Stage 3 -HEPA Cartridge:
• Inspect the HEPA Cartridge with the
lid removed.
• Unfasten the restraining strap(s)
holding the filter(s) in place.
• Place hands flat against the end cap of
the HEPA Cartridge to grip and rotate
the cartridge counter clockwise to
release it from the bulkhead.
• The loaded HEPA Cartridge and O-ring
should be bagged and disposed with
suitable procedures.
• Clean the empty housing before
fitting the replacement O-ring and
HEPA Cartridge.
• Press down firmly to compress the
O-ring as the HEPA Cartridge is
rotated clockwise to lock it on the
bulkhead.
Stage 3 - VOC Ultra Canister (Option)
• Follow instructions for HEPA Cartridge
installation.
Stage 4 - VOC Blanket (Optional):
• With the HEPA Cylinder removed from
the bulkhead, look inside the HEPA
Cylinder to locate the two ends of the
VOC blanket.
• Pull one end of the old inner carbon
filter in and bend it into a loose roll
so it can be removed.
• Remove the inner carbon filter from
the HEPA Cylinder and dispose.
• Remove plastic shrink wrap from the
new inner carbon filter.
• 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 filter surfaces and helps keep
it in place), place the rolled inner
carbon filter inside the HEPA Cylinder
and gently unroll it until the ends
‘butt’ together and the filter is snug
against the HEPA filter.
Stage 4 - VOC Canister (Option):
• Remove old carbon canister (if
installed) by pulling it out from the
inside of the HEPA filter or housing.
• If replacing an inner carbon blanket
with the carbon canister, remove
inner carbon filter by following the
steps for removing the VOC Blanket.
• Remove the plastic shrink wrap from
the new carbon canister.
• Slide the carbon canister into the
HEPA Cylinder, smaller end first. The
carbon canister should slide all the
way in until the metal edges at the
base meet the HEPA filter.
• Support the carbon canister with your
fingers so it does not slide out when
replacing the HEPA Cylinder assembly
into the unit.
