Section 2. De And Sand Filters - Zodiac Jandy Pro Series Installation And Operation Manual

Jandy Pro Series, NeverLube
®
This document gives instructions for installing a Jandy
Pro Series NeverLube Backwash Valve. The instructions
must be followed exactly. Read through the instructions
completely before starting the procedure. Please save these
instructions.
The Jandy Pro Series 2-in-1 NeverLube backwash 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). Used with the Jandy Pro Series versa-coupler, the
NeverLube backwash valve can be used on filters with
center-to-center dimensions of 7 to 9 inches.
For Jandy Pro Series Filters, NeverLube backwash
valve p/n 8034J comes ready to mount to DEL48 or
DEL60 model filters (outlet being the top port). If using
the 8034J with another model sand or DE filter, install
per label on valve. BWVL-NVL mounts to DEV48,
DEV60, or JS series filters. For Pentair® or Sta-Rite®
filters, a combination of p/n 8034 (NeverLube backwash
valve) with p/n 8044 (Versa-Coupler Kit) can be used to
mount to most models. To mount on a sand filter from
a manufacturer other than Jandy Pro Series (with the
inlet being the top port), simply flip the valve over. If the
valve handle ends up on the bottom of the valve, remove
the locking knob and handle and place on the top. Hand
tighten the locking knob. See Figure 1.

1. Turn the locking knob on the NeverLube
backwash valve counter clockwise to loosen. Turn
the handle back and forth several times to verify
the diverters move freely.
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.
WARning
never attempt to assemble,
disassemble or adjust the filter when
there is pressurized air in the system.
Starting the pump while there is
any pressurized air in the system
can cause the filter lid to be blown
off, which can cause death, serious
personal injury or property damage.
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 NeverLube backwash valve from
packaging.
4. Remove the two (2) O-rings from packaging.
5. Place O-rings on the face of the union tail pieces,
where the face of the NeverLube backwash
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.
6. Holding the valve upright, place onto the filter
bulkheads.
