5. Close the Sprinkler Valves
Make sure the bleed lever is rotated clockwise to OFF.
6. Test the System
After all pipe and fittings have been installed (allowing sufficient time for
PVC glued joints to dry—24 hours), turn the water supply on and check
for leaks with the valves closed. The valves may come on momentarily
while initially pressurizing the line, but will shut off in a few moments.
7. Open Valves
Turn the manual bleed lever counter-clockwise to manually open the
valve. Check the downstream pipe and fittings for leaks. Now close the
bleed lever. The valve will shut off in a few moments. The system is now
ready to be controlled electrically from the timer or manually by opening
the internal manual bleed lever. (Caution: Frequent manual operation of
the valve using the internal manual bleed lever is not recommended. This
type of manual operation is for trouble-shooting and occasional use.)

8. Draining
In freezing areas, the valves and lines will need to be drained. Refer to
the Orbit
Layout Guide or your local dealer to recommend proper drain
®
points. To ensure the electric valves are completely drained in the fall, turn
off the main sprinkler shut-off valve and electrically run each valve dry
for a few minutes. Turn the timer to the OFF position until next spring.
9. Filter Cleaning Service
Your 4-in-1 Drip valve filter will require routine servicing.
Monthly
Use the flush port to clean large debris from the filter (adjust frequency
based on your water condition). Before flushing ensure that the timer
is in the OFF position. Next, remove the flush cap and attach a garden
hose to the filter housing. Rotate the bleed lever counter-clockwise to
manually open the valve and let the water run for 30 seconds. Turn the
bleed lever clockwise to close the valve and replace the flush cap.
Annually
Removing fine debris from the filter. With your timer in the OFF position,
remove the filter housing by unscrewing the housing ring. Gently remove
the filter and flush with clean water. Ensuring that all four o-rings are in
place. (see figure 3). Replace housing and hand tighten the housing ring.
It is rare that your Orbit
should. If you do have any problems, try the following solutions.
The valve will
not open electrically
First, run the valve manually by opening
the manual bleed lever (turn counter-
clockwise).
Close the manual bleed lever when
manual test is complete.
Figure 3
The valve is installed incorrectly
Make sure that the arrows are in the
direction of water flow.
Wiring is incorrect
Make sure that the arrows are in the
direction of water flow. Check wiring
at the valve and at the timer with the
instructions. Check to see that timer is
working properly.
There is debris in the port hole
Turn off water. Remove the solenoid.
Push a wire or large paper clip down
through the round port hole working it
up and down to free any debris. Be sure
the plunger and o-ring are in place when
reassembling.
Defective solenoid
Turn off water. Unscrew the solenoid
and replace with one from a working
valve. If the valve works, replace the
solenoid. Be sure the plunger and o-ring
are in place when reassembling.
Solenoid plunger is stuck
Turn off water. Remove the solenoid and
clean out sand and debris. Be sure the
plunger and o-ring are in place when
reassembling.
Troubleshooting

Solenoid plunger is stuck
Turn off water. Remove the solenoid and
clean out sand and debris. Be sure the
plunger and o-ring are in place when
reassembling.
Rock or debris is between the washer
and the valve seat
Turn off water. Remove valve lid and
diaphragm assembly and clean the
interior of the valve.
Diaphragm has ruptured
Turn off water. Remove the lid and
inspect the diaphragm for tears. Replace
the diaphragm assembly if torn.
External valve leaks
PVC fittings going to valve installed
incorrectly
Use thread seal tape generously on
threads and tighten firmly. Do not over
tighten.
Pressure is too high
Install a pressure regulator upstream
of the valve and set at about 80 PSI (5.5
bars).
Leaking below solenoid
Turn off water. Tighten solenoid.
