FOR YOUR SAFETY: This product must be installed and serviced by authorized personnel qualified in pool/spa installation and maintenance. Improper installation and/or operation will void the warranty.

WARNING

Ensure that all electrical power to the system is turned off before approaching, inspecting or troubleshooting any leaking valves that may have caused other electrical devices in the surrounding area to get wet.

This document gives instructions for installing the Jandy Slide Valve. The instructions must be followed exactly. Read through the instructions completely before starting the procedure. Please save these instructions.

The Jandy Slide Valve is designed to be used on either sand or diatomaceous earth (DE) filters with a center to center dimension of eight (8") inches (center of the inlet port to the center of the outlet port). Combined with the Jandy Versa-Coupler, the Slide Valve can be used on filters with center to center dimensions of seven (7") to nine (9") inches.

For Jandy Filters, Slide Valve p/n SVLV8 (with unions) is ready to mount to DEL48 or DEL60 model filters (in which the top port is the filter outlet). If mounting a Jandy Slide Valve on Pentair or Sta-Rite Filters, use a combination of p/n SVLV2 (Slide Valve without unions) and p/n 8044 (Versa-Coupler Kit).

The Slide Valve is a two position valve. The valve handle must be fully extended or fully depressed. This valve can not be throttled. To operate the Slide Valve on a DE filter in normal filtration mode, fully depress the handle. To operate the Slide Valve on a sand filter in normal filtration mode, fully extend the valve handle (see Figure 1).

WARNING

Ensure that all electrical power to the system is turned off before approaching, inspecting or troubleshooting any leaking valves that may have caused other electrical devices in the surrounding area to get wet.

2.Turn off all power to the system. For retrofit installations only, follow steps "a" through "d". For new installations skip steps "a" through "d" and proceed to step 3.

a.Open the pressure relief valve on top of the filter. Wait for all air to evacuate the system.

b.If the filter is below pool level, close the suction and return line valves to isolate the filtration system.

c.Remove the drain plug from the filter. Let the water drain from the filter.

d.Remove the existing valve from the filter.

3.Remove the o-rings (2 total) from the packaging.

4.Place the o-rings on the face of the union tail pieces, where the face of the Slide Valve union will connect to the filter bulkheads (see Figure 2). Make sure each O-ring is properly seated into the groove of each union tail piece.
