Dealer Installation Instruction - Independent
Operation
The HEPA systems can be used independently of any other
equipment! The inlet and outlet of the filtration system can
be ducted into the same room to create a cleaner environ-
ment almost anywhere. The inlet or outlet can also be duct-
ed elsewhere. The inlet and outlet should be installed on
opposite sides of the room; however, this varies according
to your specific needs.
Example of Single Room Stand Alone System
Installation
For single rooms where increased filtration is desired such
as a dedicated ‘smoking room’.
HEPA System
A
B
Air should be drawn from
location B if space is
available, otherwise, use
location A.
Figure 15. Typical Single Room Stand Alone System
Preparations
Here are some things to consider as you decide where to
install the HEPA system independently of other systems.
1.
Location:
»
Make sure there is room to open the HEPA filter ac
-
cess panel for filter changes/inspections.
»
Keep the HEPA system away from possible water
damage.
»
Vibration pads will reduce vibration for installations
where the unit is placed on the floor.
»
Install HEPA System on floor or suspended platform.
If the unit is suspended, screws must not penetrate
through the cabinet. Make sure that you have the
proper chains/straps/joists and equipment to keep
unit secure.
2.
Inlet (Marked as ‘Air In’ on unit):
»
Inlet ducts should be installed near the floor for opti
-
mum airflow (see figure 11). If space does not allow,
then the inlet can be installed in the ceiling.
»
Inlet duct should be installed at least 8 ft. away from
the outlet duct on the main return.
»
Inlet duct should be installed at opposite end of the
room from the outlet duct(s) if in the same room.
»
Diffusers are recommended to help distribute airflow
evenly.
3.
Outlet (Marked as ‘Clean Air Out’ on unit):
»
Outlet(s) should be installed in the ceiling away from
any other air inlet(s)
»
Room diffusers are recommended to help distribute
airflow evenly in the occupied space.
4.
Ducting
»
If HEPA system is installed where inlet and outlet
collars face down, metal elbows must be connected
to both inlet and outlet collars.
»
Each connection must be sealed with aluminum
tape or mastic, including all vent connections.
»
Installed duct runs should be as straight as possi-
ble (if the duct runs are too long, reduced CFM may
result).
»
If duct is exposed to unconditioned air, insulated flex
duct is highly recommended.
»
Externally insulated flex duct can also be used for
noise reduction purposes
»
For best indoor air quality, do not use ductboard or
fiberglass inside of ducts.
5.
Electricity
The unit must be plugged into a grounded 120V, 60Hz. out-
let.
