flexible 12 inch intake duct, from the cold air return,
to be attached. The 12 inch intake must be drawn
from the cold air return duct at a location that will
be ahead of the clean exhaust air, that will be
returned to the duct from the Air Cleaner.
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 either side 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, as the door is interlocked for safety. 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. Carefully remove filters to avoid spilling of collected
contaminants. Dispose filters in a plastic bag and
discard with regular household trash.
3. Remove plastic from new filters before installing.
Discard plastic safely. Take care not to damage the
filters.
4. Date the replacement filters in the space provided.
5. Ensure that the direction arrow on filter is pointing
toward the fan blade.
6. 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 #W5-0810):
This must be
replaced every 3 - 6 months and may be vacuumed
between changes. Use a soft brush attachment when
cleaning.
True HEPA Filter (Part #W5-0860-3):
Replace every
3-5 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.
Note: Handle the HEPA filter by the frame only.
The paper is fragile and a puncture or tear will reduce
efficiency.
VOC After Filters:
The 2 inch standard or heavy-
duty optional upgrade filters 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.
Replacement VOC After Filters (2 inch):
Carbon Filter
Part #W5-0820
Carbon/Potassium
Permanganate Filter
Part #W5-0885
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.
CAUTION
The new HEPA filter may be tight to install the first
time. Do not push from the center of filter. Apply even
pressure at both corners.
