This document provides instructions for installing the
Jandy Pro Series Pro Series Slide Valve. The instructions
must be followed exactly. Read through the instructions
completely before starting the procedure. Please save these
instructions.
The Jandy Pro Series Pro Series Slide Valve is designed to
be used on either sand or diatomaceous earth (DE) lters
with a center-to- center dimension of 8 inches (center of
the inlet port to the center of the outlet port). Combined
with the Jandy Pro Series Pro Series Versa-Coupler, the
Slide Valve can be used on lters with center-to-center
dimensions of 7 to 9 inches.
For Jandy Pro Series Filters, Slide Valve p/n SVLV8 (with
unions) is ready to mount to DEL48 or DEL60 model
lters (in which the top port is the lter outlet), BWVL-
SLD mounts to DEV48, DEV60 or JS series model lters.
If mounting a Jandy Pro Series 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 DEL,
DEV or JS series lters in normal ltration mode, fully
depress the handle. To operate the Slide Valve from a
manufacturer other than Jandy Pro Series (with the inlet
being the top port) on a sand lter in normal ltration
mode, fully extend the valve handle. See Figure 1.
1. Remove the Slide Valve from the packaging.
Twist the handle on the Slide Valve several times
to verify that the piston moves freely.
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 retrot
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 lter.
Wait for all air to evacuate the system.
b. If the lter is below pool level, close the suction
and return line valves to isolate the ltration
system.
c. Remove the drain plug from the lter. Let the
water drain from the lter.
d. Remove the existing valve from the lter.
3. Remove the two (2) o-rings 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 lter bulkheads, see Figure 2.
Make sure each o-ring is properly seated into the
groove of each union tail piece.
The Slide Valve has molded labels on each port. (See
Figure 1.) The ports on the SVLV8 are equipped with
union connections that match the connections on the
filter ports. Do not use pipe sealants on union nuts.
5. Hold the Slide Valve upright and place onto the
lter bulkheads. See Figure 3.
6. Tighten both union nuts to secure the valve on the
lter.
