Section 1. SVLV8 Installation
1. Remove the Slide Valve from the packaging. Twist
the handle on the Slide Valve several times to
verify that the piston moves freely.
WARNING
FOR YOUR SAFETY: This product must be installed and serviced by a professional pool/spa service techni-
cian. The procedures in this instruction sheet must be followed exactly. 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. Failure to
do so could result in an electrical hazard that could result in death or serious injury due to electrical shock, and
may also cause damage to property and/or operation.
This document provides 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) 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
Versa-Coupler, the Slide Valve can be used on lters
with center-to-center dimensions of 7 to 9 inches.
For Jandy 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 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 (with the
inlet being the top port) on a sand lter in normal ltra-
tion 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 retrot
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.
