FILTER DISASSEMBLY/

ASSEMBLY PROCEDURE

To avoid equipment damage and personal injury, never change handle position on control valve while pump is running.

BEFORE DISASSEMBLING FILTER:

1. STOP PUMP.

2.OPEN air release valve and drain fitting.

3.WAIT until all pressure is released and water drained from filter tank and system before loosening clamp knobs.

Disassembly:

1.Backwash filter according to instructions under “Filter Backwash Procedure”, Page 9.

2.Stop pump.

3.Open air release valve (Key No. 3, Page 14) on top of filter tank to release all air pressure from inside of tank and system.

4.Remove filter drain plug and drain all water from tank.

5.To equalize flange stresses, loosen clamp knobs alternately (that is, on op- posite sides of tank) around tank. Remove clamps.

6.Being careful not to damage cord ring (Key No. 21, Page 14), lift upper tank shell (Key No. 7, Page 14) off lower tank shell (Key No. 20, Page 14).

Assembly:

1.Remove O-Ring slowly to avoid stretching or tearing it.

2.Inspect O-Ring (Key No. 21, Page 14) for cuts, nicks, etc. If O-Ring is damaged, deformed, or has lost its resiliency, replace with a new one.

3.Clean O-Ring area of tank shell (both halves) and O-Ring.

4.Carefully install O-Ring and upper tank shell (Key No. 7, Page 14) on tank bottom (Key No. 20, Page 14).

NOTICE: Do not lubricate O-Ring. Lubricants attract dirt and grit and may (especially when petroleum based) damage O-Ring and void warranty.

NOTICE: Be sure upper tank shell contacts O-Ring surface evenly and seal area is clean and free from dirt.

5.Install clamp bolts and clamps. Do not tighten clamps yet.

6.See Figures 4 and 5 for clamp tightening sequence. Tighten all clamp knobs securely hand tight.

NOTICE: To equalize stresses on tank, be sure to tighten clamps in se- quence shown. DO NOT work your way around the filter tightening adja- cent clamps.

7.Install air relief valve and gauge assembly on tank.
