Filter Installation for TBV Insertable
The filter cartridges in the TBV insertable model
extend past the bottom of the cabinet when
installed. The filter cartridges would be crushed and
damaged under the weight of the collector if they
were shipped installed; therefore, they are shipped
loose and installed at the customer site once the unit
has been installed into a permanent location.
See the Filter Element
Installation section for plenum
models.
The TBV insertable-model must already be
installed in a permanent location before the
installation of the filter cartridges into the
unit.
1. Unpack the filter cartridges from each box,
which contains a filter element, a filter crank
rod, a rubber-backed washer and a steel
grounding tab.
2. Open the TBV top roof access door to its fully
open position (small notch on bar).
Failure to open the door
properly could result in
personal injury. Ensure the door is in the
correct open position.
Once the roof is secured, reach inside the clean
air plenum of the unit and disconnect the
blowpipes by pulling back the levers of the quick
release pipe couplers. Stow the blowpipes in an
upright position by inserting them into the slots
provided at the rear of the unit.
3. Reach down inside the clean air plenum of the
unit and halfway unscrew all the black hold-
down knobs. Reach down inside the venturi,
grasp the collar bracket and twist to the right
(clockwise) until the filter hold-down collar
clears all four screw studs. Pull up and remove
the filter hold-down collar assembly from the
clean air plenum.
4. Place the new filter element end-cap down
(gasket-side up). Slide the filter hold-down collar
down inside the open end of the filter element
until it stops. Lay the filter element on its side.

5. Slide the steel grounding tab on to the filter
crank rod, followed by the rubber-backed
washer, rubber side up and away from the crank
handle.
6. 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.
7. Insert the complete filter/venturi assembly back
into the clean air plenum until the hold-down
collar is flush with the bottom of the clean air
plenum (tubesheet). Rotate the assembly to the
left (counterclockwise) until all four screw studs
are engaged.
8. Tighten all block hold-down knobs until secure.
Reconnect the blowpipes using the quick release
pipe couplers.
9. Grasp the roof access door with one hand and
with the other pull up on the bottom of the
roof support slide bar to disengage the locked
position. Lower the roof access door until it is
closed. Secure it by twisting the T-handle latches
on top of the roof.
