5.Inspect the shaft and the o-rings for wear, cuts, cracks, and debris. If the o-rings show any sign of wear or damage, replace with Jandy O-ring and Roll Pin Replacement Kit (P/N R0442100).

NOTE The o-ring inspection includes the Lid o-ring. Please be aware that the roll pins are different lengths; the handle roll pin is 1" long and the shaft roll pin is 13/16" long.

6.Wash the shaft and o-rings with clean water and dry with a lint-free cloth. Ensure that all debris is removed.

7.Wash the lid surface of the valve (where the lid o-ring is seated) and dry with a lint-free cloth.

Ensure that all debris is removed.

8.Lubricate o-rings with 100% silicone grease lubricant, like Magic Lube®. Do not use any lubricant containing petroleum products.

9.Place the shaft back into the Slide Valve and tighten the lid union nut.

11.Turn on system pump(s) and check for normal water flow.

Section 6. Winterizing

CAUTION

If not properly winterized, damage to the Slide Valve will occur, which will increase the potential of injury.

1.Turn off the system pump(s).

2.Release all pressure from the system at the main filter.

3.Loosen the lid union nut (see Figure 8).

4.Grab the Slide Valve handle and pull the shaft assembly out of the valve (see Figure 9).

5.Allow all water to drain out the valve.

6.When it is confirmed that there is no water left in the valve, place the shaft back into the Slide Valve and tighten the lid union nut.

7.Position the Slide Valve in Backwash mode (see Section 4).

(DE Filters) Ensure that the Slide Valve handle is fully extended (handle pulled all the way up). See Figure 7.

(Sand Filters) Ensure that the Slide Valve handle is fully depressed (handle and piston pushed all the way down). Turn the handle until the stainless steel pin on the piston locks into the position

bracket.
