Clean O-ring and Seal Surface
1. Clean and lightly lubricate tank O-ring (We recommend Jack's 327 Lubricant or other Non-petroleum based silicon
lubricant). Carefully place the O-ring over filter tank lip.
2. Clean upper filter body flange sealing surface.
Filter Re-Assembly Instructions
1. Re-assemble upper filter body. Insure that the filter body seal is in place and all operation labels on all filter
components are visible from a convenient location. Press down firmly and evenly to set the filter head in place.
2. Re-assemble filter clamp to tank flanges. Hold clamp ends to position clamp on tank flanges with the T-Bolt and
trunnion adjacent to the safety and operation labels on the tank. Do not bend or distort filter clamp during
positioning.
3. Insert clamp T-Bolt into clamp trunnion and thread spring nut assembly onto clamp T-Bolt with spring end towards
trunnion.
4. Using a 7/8" socket wrench, tighten spring nut assembly while tapping outer band of Filter Body Clamp with rubber
mallet to insure proper seating of upper and lower tank bodies and clamp. Tighten spring nut assembly until bolt
extends 1/8" past the nut, and each spring coil touches the next coil. Never rely on hand tightening of spring nut
assembly.
5. Follow Operation Instructions for "Starting the Filter" (Page 4)
VACUUMING
Vacuuming can be performed directly into the filter whenever needed. Clean cartridges after vacuuming, if required.
WINTERIZING
Winterizing Filter
In areas where subfreezing temperatures can be expected, the filter should be drained. Remove and clean the
cartridges.
Reinstall cartridges in filter tank.
Be sure to leave the drain plug unattached during the winter season to avoid cracking the filter tank.
