4. A duct adapter and a length of 12 inch flexible hose
or duct is required to attach between the 12 inch
intake collar and the existing cold air return duct.
When running the hose, make sure that there are
no kinks or sharp bends that will impede the air flow
to the unit. Secure and seal the hose and
connections to prevent air leakage.
5. The 8 inch exhaust collar can be conveniently
mounted on one of three sides of the unit. A duct
adapter and a length of 8 inch flexible hose or duct
is required to attach between the exhaust collar and
the existing cold air return. The exhaust hose should
be attached to the return air duct, close to the
furnace. The ideal location is low on the return air
boot pointing at the furnace. To prevent air shear
inside the duct, it is recommended that you install a
deflector inside the boot, so the discharged air is
deflected down into the boot. When running the
hose, make sure that there are no kinks or sharp
bends that will impede the air flow from the unit.
Secure and seal the hose and connections to
prevent air leakage.
6. It is important to maintain some distance between
the intake and the exhaust openings in the return air
duct. Failure to do this may result in short cycling
between the intake and the clean air discharge. It is
recommended you leave 10 feet between the intake
and the exhaust; however, as little as 6 feet will work
effectively. If the distance is smaller than 6 feet, it is
important that an air deflector is installed in the duct.
7. 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.
OPERATING INSTRUCTIONS
The HEPA Air Cleaner is designed to run continuously
to provide clean, filtered air 24 hours a day. The fan on
the heating/cooling system, to which the HEPA Air
Cleaner is dependent on for circulated air, should be on
‘continuous’.
Note: If the system fan setting is on ‘automatic’, it is
recommended the HEPA Air Cleaner be operated
through an air switch or relay to turn the Air Cleaner off,
when there is no system fan on.
The unit plugs into a regular 120 volt outlet and is
controlled by a switch located on the rear panel, near the
cord.
Note: Do not allow the cord to be placed where it may
be walked on or allow anything to roll over it.
The door must be secured for the Air Cleaner to
operate. All filters must be in place for the unit to
operate properly.
MAINTENANCE
For efficient operation, the filters must be changed on a
regular basis. If you notice a reduction in air flow from
the system, check the filters.
1. To access the filters, turn the Air Cleaner
OFF
at the
switch and remove the front door.
2. Release the filter hold down bar by pulling it forward
one side at a time.
3. Carefully remove filters to avoid spilling of collected
contaminants. Dispose of filters in a plastic bag and
discard with regular household trash.
4. Remove plastic from new filters before installing.
Discard plastic safely. Take care not to damage the
filters.
5. Date the replacement filter in the space provided.
6. Place the Carbon prefilter around the HEPA filter
and secure with the Velcro.
7. Ensure the open end of the HEPA filter is toward the
motor.
8. Replace the filter hold down bar by placing one side
under the bracket on the side of the cabinet. Once
you have one side started force the bar under the
bracket on the other side of the cabinet. This
insures the filter has a good seal.
9. Use genuine replacement filters only. Call the
original installer for parts.
Note: When the filters are new, you may notice a new
smell from the system. This is normal and will dissipate
within a few days.
Carbon Prefilter:
This must be replaced every 3 - 6
months and may be vacuumed between changes. Use
a soft brush attachment when cleaning. If there are
heavy odors in the home from cooking, smoking,
painting or other sources, the filter will require changing
more often.
True HEPA Filter:
Replace every 2-4 years. The life of
this filter depends on the amount of contaminants in the
air and the frequency in which the prefilter has been
changed. Renovations in the home that create wood,
drywall dust or similar contaminants will shorten the life
expectancy of the HEPA filter. To improve airflow, the
HEPA filter can be vacuumed between changes,
preferably outdoors. Use a soft brush attachment for
vacuuming this filter.
Note: Handle the HEPA filter by the frame only. The
paper is fragile and a puncture or tear will reduce
efficiency.
VOC After Filter (optional):
This filter is positioned
inside the HEPA filter, and must be replaced every 6-12
months. If there are heavy odors in the home from
cooking, smoking, painting or other sources, the filter
may require changing more often.
WARNING
Never use the unit without all of the filters in place.
CAUTION
Make sure to turn Air Cleaner
OFF
before performing
any maintenance or removing any components.
