• Hayward Slide Valve Manual

The SP-410x62 Series Piston Slide Valve Assembly is designed specifically for use with the Hayward Pro Series High Rate Sand Filters shown here. The Slide Valve is attached to the side of the Filter and has two modes of operation: Filter and Backwash. This guide shows you how to operate a Hayward two function Slide. New pool owner here and I have a Hayward SP722-D slide valve attached to DE6020 DE filter. I can't find a manual on the internet for the and want to make sure that I'm back washing and charging correctly. This will be my first time to back wash. Here is what I think the sequence may be: Turn off pump, unlock valve and pull up, turn on pump for.

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-RiteFilters, use a

combination of p/n SVLV2 (Slide Valve without unions) and p/n 8044 (Versa-CouplerKit).

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).

Mode(SVLV2 shown)

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

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 installationsonly, follow steps 'a' through 'd'. Fornew 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-ringson 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 eachO-ringis 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.

Figure 4. Jandy Versa-Coupler

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 filter, use Pentair Pool Products™ Union Set #27002, and then proceed to section B. If using a Sta-ritefilter, useSta-Rite®Union Set #PKGM188, then proceed to section B.

5.Hold the Slide Valve upright and place onto the filter bulkheads (see Figure 3).

6.Tighten both union nuts to secure the valve on the filter.

7.Place filter 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.

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.

11.When the glue is dry, start the system and check for proper water flow.

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 toSection 4 for Backwash mode operation instructions.

Section 2. SVLV2 and Versa-Coupler

Installation

NOTE Certain filters may require only one (1) versacoupler (p/n 8044).

1.Slide one versa-couplerintoPORT C and one intoPORT D on the Slide Valve.

2.Hold the Slide Valve up to the filter and twist the versa-couplersuntil they slide into the filter inlet and outlet ports.

NOTE Make sure to align eachversa-couplerto the filter 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 filter. Clean the versacouplers and glue them onto the valve using the alignment marks as a reference.

4.Clean the versa-couplerand glue onto the filter. 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.

NOTE Refer to Figure 5 for Steps 6 and 7.

6.(DE Filters) Plumb the Slide Valve outlet labeledPORT A to the heater or pool return lines.

(Sand Filters) Plumb the Slide Valve outlet labeledPORT E to the heater or pool return lines.

7.(DE Filters) Plumb the Slide Valve outlet labeledPORT E to the waste line as needed.

(Sand Filters) Plumb the Slide Valve outlet labeledPORT A to the waste line as needed.

8.Allow the connections to dry for 24 hours.

9.When the glue is dry, start the system and check for proper water flow.

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 toSection 4 for Backwash mode operation instructions.
