Yoke, Venturi and Filter Installation
Installing yokes requires two
people.
1. From the clean air plenum (to access, remove the
outlet cover, see Detail I), thread a 3/8-in hex jam nut
and 3/8-in flat washer to the shoulder of each of the
three yoke rod ends. See Detail G.
2. Starting at the top access port work downward.
Orient the yoke as shown in Detail E and insert
into the housing so the yoke is positioned in the
appropriate holes in the tube sheet. From the filter
section, have one person hold the yoke in position
while another person installs a 3/8-in flat washer and
3/8-in hex nut on each yoke rod end from the clean-
air plenum. Do not tighten hardware at this time.
3. Adjust jam nut against the filter cartridge panel. Have
one person hold the yoke in position as shown in
Detail F while another person tightens the three hex
nuts from the clean-air plenum. Repeat to install all
yokes.
4. Apply sealant to venturi as shown in Detail H. Slide
venturi over the yoke with sealant end first. Hold
venturi in place while installing venturi hardware
(7/16 x 3/4-in thread forming screws and 1/2-in
gasket washers) from the clean-air plenum.
5. Slide the filter cartridges into the collector on the
yoke gasket-end first. Replace access cover and
tighten securely by hand following instructions found
in Maintenance Information. Repeat for all filter
cartridges.
6. Replace the outlet cover on the bottom of the clean-
air plenum shown in Detail I.
