Figure 10: Sealant tape on Vacuum Seat
5. Apply PTFE sealant tape around the inside hole pattern of
the vacuum seat [18] (Figure 10). Tape should be at least
1/16” thick. Note: Other sealants (such as Silicone) can
replace the fluoropolymer tape if compatible with tank
products.
6. Position the vacuum seat [18] as shown from beneath the
pallet.
7. Align vacuum seat with pallet and insert 4 bolts (at 90
degrees from each other) from the top using fasteners
shown in Figure 9 [7, 19, 20, 21].
8. Insert four more bolts, leaving four holes, at 90 degrees from
each other, open. The weatherhood posts are installed in
these holes.
9. Turn pallet assembly right side up, and place on support blocks again.
10. Run 3/8” hex nut up 1 1/2” from end on all thread and insert weatherhood posts [27] in remaining
holes. A Fluoropolymer washer, flat washer and nut are installed from the bottom. Allow
approximately 2 threads past the nut to be free. The four weatherhood posts should all extend
approximately 11.13” above the pallet.
11. Lower the weight plate [29] (if needed for setting).
12. Use a sealant tape around the inner edge of the weight plate. Note: Other sealants (such as Silicone)
can replace the Fluoropolymer tape if compatible with tank products.
13. Insert the waterdam [28] using the weatherhood posts [27] as a guide. Use sealant tape on bottom
side, outside of its hole pattern. Tighten nuts. Note: Do not over-tighten. It is suggested to first
hand tighten the nuts, torque 15 ft-lbs in an alternating criss-cross pattern.
14. Insert the spacers [12], and the stem guide [17]. Tighten nut to retain to pallet assembly.
15. If pallet assembly is high enough from the table, insert vacuum pallet-stem [23, 24, 14] assembly
from beneath. Place a short length of pipe (minimum 6” high) beneath the vacuum assembly to hold
it in place until the spring is installed.
