a.
Apply sealant, or a closed-cell foam gasket material, to the
flange attachment surface on the inlet side of the safety filter
assembly. Attach the transition duct, using the duct flange
doublers provided.
b.
Move the filter assembly, together with any required transition
ducting up to the rear of the AirWall unit. Align the open end of
the transition ducting with the fan exhaust duct flange. Apply
sealant or a closed-cell foam gasket material to the fan exhaust
flange-mating surface.
NOTE: In reference to Steps A and B, neither a support platform nor
a transition duct is provided due to differences in facility installation.
c.
Open the access doors.
d.
Slide the pre-filters into the slots provided. Make sure the air flow
direction is correct.
e.
Install the HEPA or safety filter on the back wall of the filter
stand. The gasket will seat on the metal frame. Once the filter is
in place, swing the locking bolts into position so that the locking
bolts hook on the edge of the filter corners.
f.
Evenly tighten all four (4) corners to 29 in. lbs. (3,3 Nm).
g.
Close the access doors. Position the positive sealing latches on
both sides of the access doors and tighten to provide a 50 percent
gasket compression.
NOTE: Refer to the HEPA filter manufacturer’s product documen-
tation for specific information regarding your HEPA application or
installation.
ELECTRICAL CONNECTIONS
The electrical requirements for the exhaust blower motor are 208/230/460 VAC, 3-
phase, 60 Hz power. Only a qualified electrician should connect this device to an
appropriate motor starter.
NOTE: Whenever possible, EECI attempts to deliver the fan motor
wired for your specific voltage requirements. It is recommended,
however, that your electrician verify the motor terminal connec-
tions to ensure proper wiring for your installation.
