Filter Element Installation
See the Filter Installation
for TBV for first time filter
installation for insertable models.
1. Place the new filter element end-cap down
(gasket-side up). Slide the filter hold-down collar
insidetheopenofthefilterelementuntilitstops.
2. Slide the steel grounding tab through the filter
crank rod, followed by the rubber-backed
washer, rubber side up and away from the crank
handle.
3. Slide the filter crank rod through the hole in the
filter element end cap and up through the filter
cartridge. Align the filter crank rod end with the
quick-nut assembly located in the center of the
hold-down collar bracket and screw together
until the filter cartridge forms an air-tight seal
against the filter hold-down collar.
4. Insert the complete filter/venturi assembly back
into the clean air plenum until the hold-down
collar is flush with bottom of the clean air
plenum (tubesheet). Rotate the assembly to the
left (counterclockwise) until all four (4) screw
studs are engaged.
5. Tighten all black hold-down knobs until secure.
Reconnect the blowpipes using the quick release
pipe couplers.
6. Grasp the roof access door with one hand and
pull up on the bottom of the roof support slide
bar with the other to disengage the locked
position. Lower the roof access door until closed
and secure by twisting the T-handle latches on
the top of the roof.
