5. A duct adapter and a length of 6 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 top cover 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 top cover.
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 ensures 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 (Part #W3-0855):
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 (Part #W3-0840):
Replace every 2-
3 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 (Part #W3-0810 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.
