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) filters
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 filters 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
filters (in which the top port is the filter outlet), BWVL-
SLD mounts to DEV48, DEV60 or JS series model filters.
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 filters in normal filtration 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 filter in normal filtration
mode, fully extend the valve handle. See Figure 1.
section 2. 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
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 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 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 filter bulkheads, see Figure 2.
Make sure each o-ring is properly seated into the
groove of each union tail piece.
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.
5.
Hold the Slide Valve upright and place onto the
filter bulkheads. See Figure 3.
6.
