This valve can
not be throttled.
a. Installation
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.
1. Remove the slide valve from the packaging.
Twist the handle on the slide valve several times
to verify that the piston moves freely. If any of
the components show signs of damage please
call Zodiac at 1-800-822-7933.
2. Turn off all power to the system.
• For
new
installations steps “3” through “6” may
be skipped. Proceed to step 7.
3.
Open the pressure relief valve on top of the
filter. Wait for all air to evacuate the system.
4. If the filter is installed below pool level, close
the suction and return line valves to isolate the
filtration system or ensure that proper isolation
check valves are in place.
5. Drain the water from the filter. Please follow the
filter manufacturers draining instructions and
ensure that wastewater is disposed of properly.
6. Remove the existing valve from the filter.
7. Remove the two o-rings from the packaging.
8. Place the o-rings on the face of the union tail
pieces, where the face of the union will connect
to the filter bulkheads, see Figure 4.
• Make sure each o-ring is properly seated into
the groove of each union tail piece.
•
The slide valve has molded labels on each port.
• The ports are equipped with union connections
that match the connections on the filter ports.
• DO NOT USE liquid thread sealant on any
threaded plastic connection.
9.
Hold the slide valve upright and place onto the
filter bulkheads. See Figure 5.
10.
Tighten both union nuts to secure the valve on
the filter.
11. Follow filter manufacturers instructions for filter
placement on the equipment pad.
12. Plumb the discharge of the pump into the slide
valve inlet labeled
PORT B.
13. Plumb the slide valve outlet labeled
PORT A
to
the heater or pool return lines.
14. Plumb the slide valve outlet labeled
PORT E
to
the waste line as needed. Allow the connections
to dry for 24 hours.
15.
When the glue is dry, start the system and check
for proper water flow.
16. 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 c. for
Backwash mode operation instructions.
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.
