TIPS:
• Be careful not to allow dirt to get into the water delivery system on the entry section.
• Gasket end of each flume section goes uphill.
• The Entry Section Support bolts to the inside of the Entry Section. There are
four 3/8” bolts, 2 on each side.
• Anchor supports attach to the down slope side of the flange. (Fig. 3)
• Each flange has 7 bolts. Five bolts are 3/8” (Fig. 3 positions 1, 4, 5, 6, 7) and
two bolts are 1/2” (Fig. 3 positions 2,3). The anchor supports (where required)
attach to the 1/2” bolts. Use Anti-Seize (in BYOS-101 Combo Kit) on all bolts.
• Insert bolts in this order: bolt, flat washer, flanges, flat washer, lock washer, nut.
On flanges that require anchor supports insert bolts in this order: bolt, flat
washer, flanges, anchor support, flat washer, lock washer, and nut.
• Insert and hand tighten all the flange bolts. Then, utilizing a torque wrench,
tighten each nut to approximately half of the maximum 25 ft. lbs. Tighten the
bolts in an alternating fashion working from left to right starting with the center
bolt, then tighten the two 1/2” bolts, working your way up the flange (Fig. 3).
Repeat this same tightening process until the specified 25 ft lbs is reached on
each bolt. Do not over tighten. Using greater force may fracture the fiberglass.
Tightening the bolts in this sequence is necessary to compress the gasket evenly.
