Additional Steps for Models VH 2-16, 2-20, 3-24 and
3-30
After you install the first two filters in the cabinet
(1-left and 1-right), the front portion of the support tray
must be attached. To attach the front section of the filter
tray:
a. Slide the rear portion of the support tray towards
the back of the cabinet, exposing the front roller
bearing.
b. Position the rear of the front tray section on the
front roller bearing.
c. With the front of the tray pressed down, slowly
slide the tray into the cabinet until it contacts the
v-frame tubesheet.
d. Lift the front of the tray to a horizontal position
and pull the tray slowly forward until it drops
onto the roller. Then push the tray back into the
cabinet roughly 1/3 of its length. (10-12 inches).
It should now be in contact with the rear section
of the tray.
e. Align the front and rear sections of the tray and
install the clevis pins on both sides.
f. Position the assembled tray so the installed
filters are just inside the cabinet.
g. Repeat filter installation steps 2 – 6 until all
filters are installed and the tray is fully inside the
cabinet.
9. Grab the handle of both filter packs and press firmly
to ensure the filters and tray are all the way to the
back of the cabinet. The front edge of the filter
packs should not project past the v-frame tubesheet.
