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.

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.
7. Place lter and valve in proper location on the
equipment set pad.
8. Plumb the discharge of the pump into the Slide
Valve inlet labeled
PORT B .
9. Plumb the Slide Valve outlet labeled
PORT A to the
heater or pool return lines.
10. Plumb the Slide Valve outlet labeled
PORT E to the
waste line as needed. Allow the connections to dry
for 24 hours.
11. When the glue is dry, start the system and check
for proper water ow.
NOTE: For new installations other than Jandy DEL48
or DEL60, use the SVLV2 and the Versa
Coupler Kit, p/n 8044. See Figure 4.
If using the Slide Valve with a Pentair® lter, use
Pentair Pool Products®* Union Set #27002, and
then proceed to Section 2. If using a Sta-Rite®
lter, use Sta-Rite® Union Set #PKGM188, and
then proceed to Section 2.
Section 2. SVLV2 and Versa-Coupler
Installation
NOTE Certain lters may require only one (1) versa-coupler
(p/n 8044).
1. Slide one (1) versa-coupler into PORT C and one
(1) into
PORT D on the Slide Valve.
2. Hold the Slide Valve up to the lter and twist the
versa-couplers until they slide into the lter inlet
and outlet ports.
NOTE Make sure to align each versa-coupler to the
lter and the Slide Valve prior to gluing the
assembly. When the parts are in alignment,
mark each piece to ensure correct reassembly.
3. Remove the valve from the lter. Clean the versa-
couplers and glue them onto the valve using the
alignment marks as a reference.
4. Clean the versa-coupler and glue onto the lter.
Hold the coupler in place for a minimum of one
(1) minute.
5. Plumb the discharge of the pump into the Slide
Valve inlet labeled
PORT B .
CAUTION
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.

CAUTION
Do not let any adhesive get inside the Slide Valve
body. Adhesive inside the valve body will prevent the
piston from moving freely, or cause the valve to leak.
CAUTION
To avoid costly equipment damage, after verifying
proper water flow and prior to putting system into
normal operating conditions, flush the system using
Backwash mode until the waste water is clean.
Refer to Section 4 for Backwash mode operation
instructions.

Section 3. Normal Operation
WARNING
NEVER attempt to assemble,
disassemble or adjust the lter when
there is pressurized air in the system.
Starting the pump while there is
any pressurized air in the system
can cause the lter lid to be blown
off, which can cause death, serious
personal injury or property damage.
1. Turn off the system pump(s).
2. Open the air release valve on top of the lter tank
to release all pressure from inside the tank and
system. Wait for all the air to evacuate the system.
3. (Jandy DEL, DEV, and JS series 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.
(Other Manufacturers Filters with the lter
top port as the inlet) Ensure that the Slide Valve
handle is fully extended (handle pulled all the way
up).
4. Turn on the lter pump(s). Check the system for
normal water ow.
