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.

lubricant, like Magic Lube®*II. Do not use any

lubricant containing petroleum products.

9. Place the shaft back into the Slide Valve and

tighten the lid union nut.

10. Return the Slide Valve handle to the normal

operating position. See Section 3.

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

assembly out of the valve. See Figure 9.

5. Allow all water to drain out the valve.

6. When it is conrmed 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.

(Jandy DEL, DEV, and JS series Filters) Ensure

that the Slide Valve handle is fully extended

(handle pulled all the way up). See Figure 7.

(Other Manufacturers Filters with the lter
