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 environment almost anywhere. The inlet or outlet
can also be ducted elsewhere. The inlet and outlet should be installed on opposite sides of the room; however,
this varies according to your specific needs.
Preparation:
Here are some things to consider as you
decide where to install the HEPA system
independently of other systems.
Location:
Make sure there is room to open the
HEPA filter access 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.
Inlet (Marked as ‘Air In’ on unit):
Inlet ducts should be installed near the floor for
optimum 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.
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.
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 possible
(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
