Check if the shipping covers on the lens are still installed. If so remove the gold opaque lens cover from the bottom of the
sensor lens.
If this doesn't help:
2. Check Battery
Follow steps 1,2 & 3 from the
battery pack replacement
(Problem 1 - page 1)
If this doesn't help : check the sensors

1. Check Sensor
Step 4
Remove the four screws from the
microprocessor and seperate the lid from the
base.
Step 6
Install the adjacent working sensor in the
non-working position
Step 5
Remove the defective sensor by
depressing the phone jack tab and
gently pulling the wire out of the slot.
The problem should travel with the non-working sensor and the adjacent sensor should activate the solenoid valve.
If not: see point 4. Check Solenoid Valve.
To reinstall, reverse the above process.

Step 3
Lift the head up and gently place the front
into the bowl.
Step 2
Remove mounting allen screws that secure
the head to the bowl.
3. Check Sensor

1. Check Sensor
Step 5
a. Activate the appropriate sensor
for testing the valves status.
b. If the above sequence
determines the solenoid valve is
inoperative then the valve must
be cleaned or replaced.
After the valve is cleaned
reinstall in the reverse order.
Make Sure the lead is facing the
brass !
Step 4
Swap the two leads for determining if
the problem is the valve or the lead

4. Check Solenoid Valve
Step 1
Follow steps 1,2 & 3 from the sensor-
checking
Step 2
Remove the solenoid valve lead from
the suspected bad valve and an
adjacent working valve. This is done by
removing the screws from the center of
the solenoid valve leads at the
solenoid valve.
Step 3
Remove the solenoid valve leads from
the solenoid valve by gently pulling
straight up with pliers or prying up
between the solenoid valve and the
solenoid lead. Use caution not to
damage the gaket between the valve
and the lead.

Step 2
Remove the four screws that travel thru
the coil into the brass water body.
Step 1
Seperate the electrical
part of the valve from
the water part.
This is described above
in the solenoid valve
replacement (steps 1,2
& 3).
Step 2
Remove the core and the core
spring from the core housing.
Clean core, core spring, core
housing and water outlet from the
solenoid valve
Step 3
Replace core spring inside
core, and reposition both
elements inside the core
housing (core spring first).
Step 4
Place back O-ring, which joins the
electrical and the water part of the
valve, in its groove around the core
housing, and re-position the
electrical part on the water part of
the valve.
Insert 4 round head solenoid screws
and tighten firmly.

Step 1
Follow steps 1,2 & 3 from the solenoid valve
checking (page 3 of the trouble shooting
guide)
Step 3
Turn the brass water body counter
clockwise and remove any remaining
thread sealant. After the valve is
replaced reinstall in the reverse order
making sure the brass water body is
properly sealed to the manifold.

4.1. Solenoid Valve Replacement
4.2. Solenoid Valve Cleaning

Step 1
Follow steps 1, 2, 3 & 4 from the sensor
checking.
1. Remove lid from distribution head;
2. Remove mounting allen screws;
3. Lift head up;
4. Open the microprocessor
Step 3
Disconnect the battery by depressing
the Battery terminal Lock and gently
pulling the two halves apart.
Make note that when reinstalling the
sensors and solenoid wires it is
imperative that each valve and
sensor is paired up correctly.
Step 2
Check that all connections are secure.
IF THIS DOESN'T HELP, CHECK THE MICRO-PROCESSOR
5. Check the Micro-Processor

Step 1
Follow steps 1, 2, 3 & 4 from the sensor
checking.
1. Remove lid from distribution head;
2. Remove mounting allen screws;
3. Lift head up;
4. Open the microprocessor
Step 3
Use caution not to damage the
gasket between the valve and the
lead.
After the lead is replaced, reinstall
in reverse order.
Step 2
Remove the screws from the center of the
solenoid valve lead at the solenoid valve.
Unplug the solenoid valve leads from the
solenoid valve by gently prying up
between the solenoid valve and the
solenoid lead.
4.3. Replace Solenoid Lead
Sanifount®- Sensor Operated
INTERSAN®SANIFOUNT®REPAIR GUIDE

... Replace the Micro-Processor
Step 1
Unplug the solenoid valve wires from
the microprocessor by gently pulling
them straight out.
Use caution not to damage the
connection for the wire.
IF ALL OF THE ABOVE FIELD DIAGNOSTICS HAVE DETERMINED THE NECESSITY TO REPLACE THE MICROPROCESSOR ...
PROBLEM 4: CONTINUOUS WATER FLOW
Check Solenoid Valve
In some cases the filters may not be enough to eliminate the debris from jamming the solenoid valve in the
open or closed position.
In this case clean the solenoid valve (page 5 of the trouble shooting guide).
PROBLEM 5: REPETITIVE WATER FLOW
Check the Sensor
Some times when a unit has a bad sensor the water system will activate without someone present. To test this
in the field it is necessary to exchange the faulty station with one that is working correctly.
In this case follow the procedure on page 2 (check sensor) and replace the non-working sensor with a new
one
NOTE : In the above case the two components that are NOT defective are the battery and the solenoid
valve.
The battery because it has enough power to cycle the solenoid valve.
The solenoid valve because it opens and closes completely.
