INSTALLATION
LOCATION
The HEPA Air Cleaner can be installed directly on
the return air duct eliminating the need for
external ducting. The unit can also be mounted on
the floor, a wall or be suspended from the ceiling
and with the use of collars, be ducted into the
return air plenum. Care should be taken to keep
the unit away from an area where there is a
possibility of moisture leaking on to it.
Ensure
there is at least 15 inches in front of the unit to
allow removal of the filters and lamps.
GENERAL INSTALLATION STEPS
(Duct Mount) (see Fig. 1)
1. Before installing, remove any packaging.
Open the door and remove the filters.
Remove the lower panel on the front of the
unit to remove PCO and VOC filters and the
lamps and gloves which were packed at the
bottom of the unit. See Maintenance for
instructions to remove the filters.
2. If the unit is to be mounted on the return air
plenum, it must be installed after the last
return branch connection on the plenum. If
outside air is introduced into the return air
duct, either through a HRV (Heat Recovery
Ventilator) or direct, it should be added to the
system before the intake inlet to the Air
Cleaner.
3. Tape the mounting template level on the
plenum and proceed to cut and drill the
necessary holes as marked.
4. Remove the plastic film covering the back
holes and snip the small joints in the middle
of the mounting flaps on the back of the unit
as indicated on the template.
Do not open
the holes on the top or bottom of the unit
if you are duct mounting the Air Cleaner.
Bend all the flaps outward slightly less than
90 degrees, except for the upper bottom flap
which is only bent up 45 degrees. This
bottom flap will act as a deflector for the
exhaust air entering back into the plenum.
5. Place the gasket material around the two
openings on the back of the air cleaner.
6. Place the unit on the plenum so the flanges
are placed through the holes cut in the duct.
Fold all the flanges, except the upper bottom
flap, over to enclose the duct between the
flanges and the unit. The upper bottom flap is
only bent up 45 degrees.
7. Secure the unit to the duct with the screws
provided.
WARNING
If you are installing this unit directly to the duct without
using collars,
DO NOT
open the top or bottom collar
mounting holes on the unit.
