Location
The HEPA air cleaner should be located as close to the
return air duct as possible. This allows for shorter lengths of
ducting, which helps keep the static pressure lower. The unit
can be adapted to mount on a wall or be suspended from
the ceiling. Care should be taken to keep the unit away from
an area where there is a possibility of moisture leaking on it.
Ensure there are 36 inches in front of and above the unit to
allow for removing and replacing the filters.
Installation Steps
1. Remove any packaging or plastic from filters before
installing. See Maintenance section for instructions
to remove the filters. Cut wire ties from filter hold-
down bar.
2. When the unit is shipped, the inlet and outlet collars
are reverse- mounted to prevent damage in shipping.
The collars must be removed and reattached with the
collar ring facing out.
3. An inlet collar is provided on the unit to accommo-
date a length of 8-inch flexible duct connected to
the cold air return. The 8-inch inlet must be attached
to the cold air return duct at a location ahead of the
clean air outlet from the air cleaner.
4. A duct adapter and a length of 8-inch flexible duct are
required to connect the 8-inch inlet collar to the cold
air return duct. When running the flexible duct, make
sure that there are no kinks or sharp bends that will
impede the airflow to the air cleaner. Secure and seal
all connections to prevent air leakage.
5. A duct adapter and a length of 6 inch flexible duct are
required to connect the outlet collar to the cold air
return of the HVAC system. The outlet flexible duct
should be attached to the return air duct, close to
the furnace. The ideal location is low on the return
air boot pointing towards 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 flexible duct, make sure that there are no kinks
or sharp bends that will impede the airflow from the
unit. Secure and seal the hose and connections to
prevent air leakage.
6. It is important to maintain some distance between
the inlet and the outlet connections to the return
air duct. Failure to do this may result in short cycling
between the inlet and the clean air discharge. It is
recommended you leave at least 6 feet between the
inlet and the outlet connections for the air cleaner to
work effectively. If the distance is smaller than 6 feet,
it is important to install an air deflector in the duct.
7. If outside air is introduced into the return air duct,
either through an HRV / ERV (Heat or Energy Recovery
Ventilator) or by a direct ventilation duct, it should enter
the return duct upstream of the 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 should be set to
‘continuous’ operation.
Note:
If the system fan is set to `automatic’ operation,
it is recommended the HEPA air cleaner be operated
through an air proving switch or relay to turn the air
cleaner OFF, when the system fan is not running.
The unit plugs into a regular 120 VAC outlet and is
controlled by a switch located on the rear panel,
near the power 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.
i
CAUTION!
This unit must be installed on the return air side of the
system only. Do not connect to supply side.
Do not install in a cooking area or connect directly to
any appliance.
i
CAUTION!
Never use the unit without all of the filters in place.
