Installation notice!
Check Rough-in location and flush lines prior to hook up!
When installing the Willoughby Industries’ WAW, WAF, or WWF series
washfountains or lavatory deck systems:
Before Step 1 of the installation instructions, ensure that rough-ins are in the correct
location.
It is essential that the water supply lines be thoroughly flushed prior to making final
connection to the hot and cold water supply lines. These lines must be flushed
sufficiently to remove the small particles of debris that are inherent with new
construction projects. If this debris is not removed, the valving in these units will be
damaged. Do not attempt to remove aerators to flush debris into the lavatory. The
damage can only be fixed by replacing the valves. Damage to valves caused by debris
will not be covered by the manufacturers warranty.

When installing the Willoughby Industries' E1L1 and E1L2 Lead-free Electronic Series Valves:
Before step 1 of the installation instructions, ensure that rough-ins are in the correct location�
The valve assembly, including the spray head, MUST NOT BE connected until after
all lines have been ushed to remove the small particles of debris that are inherent
with new construction projects and all chemicals that are used in ushing are purged
from the system�
Chemicals used in ushing plumbing systems can attack the internal components of
the valve and spray head and severely damage them, so any ushing of the system
must be followed by a full ushing with pure water to clear any harsh chemicals
remaining in the system� Debris in the system if allowed to enter the valve assembly
and spray head can cause poor performance or outright failure�
Again DO NOT attempt to connect the valve assembly and spray head until after all
ushing is complete and pure water is the only media that will be passing through the
system� Damage to the valve assembly or spray head caused by harsh chemicals or
debris will not be covered by the manufacturer's warranty�

Installation Instructions
(1) Clear and ush all supply lines to valves.
(2) Mount the valves at any convenient location. Make sure to have su󰀩cient length of wire
leads to reach between the electrical piezo switches and the valves�
(3) Connect water supply lines to valves� Close the check stop valves�
(4) Assemble the push buttons to the xture backsplash. Connect the push button wire leads to
the timer assembly or Water Management System�
(5) Connect the valve wires from the timer or Water Management System to the solenoid valves�
(6) Install 3/8" MPT x comp. plastic adapter into ller/bubbler or shower head, on xture.
(7) Insert one end of plastic tube into adapter on ller/bubbler or shower head, and the other
end into adapter on valve assembly�
(8) Open water supply stops and checkstop valves, checking for leaks�
(9) Connect the power supply transformer into a 110 volt power source�
(10) Actuate push buttons several times to clear water lines and valves of trapped air� Check for
leaks at all connections�
(11) Adjust hot and cold water mixing valve, if applicable, by pressing pushbutton and realeasing
to start the water owing.

Fitting Instructions
Note: It is not necessary to disassemble this fitting for application. Merely insert tubing to stop and
tighten seal.
1. Cut tubing end squarely and remove the internal burrs.
2. Insert the tubing through the back of the nut all the way through the nut assembly to the tube stop
in the fitting body (see illustration). If the tubing does not enter the nut easily, loosen the nut one turn
and reinsert the tubing all the way to the tube stop in the fitting body.
3. Turn the nut hand tight.
4. Wrench tighten the nut 1½ - 2 turns.
5. All nuts must be retightened when the system reaches projected operating temperature.
Note: To ensure proper assembly, tubing MUST be fully inserted into the fitting body all the way to
the tube stop.
Note: Squeaking sound when tightening nut is normal. For pipe threaded connections, Teflon tape
must be used.

Electronic Valve Assembly Operation and Maintenance
Care and Maintenance
The Willoughby Electronic Valve Assembly is designed as an electrically operated, normally closed
valve, low voltage valve� This type of valve is used for lavatories as well as showers�
A strainer/checkstop is an integral part of the valve assembly and provides a means of shutting o󰀨 the
water if the valve needs servicing. A check valve in the checkstop eliminates cross ow of hot or cold
water into the opposite supply line� Fine mesh stainless steel strainers keep normal line debris from
interfering with the mechanical components of the valves�
By virtue of its design, the electronic valve is a 24 VAC operated valve and is a normally closed valve�
The operating sequence of the valve begins with pressing the push button. Based upon what the
valve is connected to, a timer or a water management system, the valve will open and stay open until
the voltage stops�
The valve contains a valve seat, water side diaphragm, an armature and a coil� When voltage is
applied to the coil, the armature is pulled upwards� The water pressure will then push up against the
rubber diaphragm and water will ow thru to the outlet side of the valve.
The bypass hole is the rubber diaphragm assist the valve in closing. The bypass orices are molded
in the edge of the diaphragm. Both of these orices must be clear for the valve to function properly.

Troubleshooting Electronic Valves
VALVE LEAKS, WILL NOT OPEN, OR WILL NOT SHUT OFF:
(1) Make sure the checkstop/strainer on the supply line to the valve is fully open� Do not partially close
the checkstop for any reason as it is not a throttling valve� The check stop should be fully open
(normal operation) or fully closed (when servicing the valve)�
(2) Close the check stop, then remove the cap� Remove and inspect the strainer in the supply line to
make sure the strainer is not blocked or partially blocked and prohibiting water ow.
(3) Check the voltage at the valve for 24 VAC after pressing the pushbutton�
(4) Verify that the appropriate DIP switches are in the "ON" position on the timer (if applicable)�
(5) If the above steps do not solve the problem, follow the steps below to disassemble and inspect the
valve:
a) Separate valve motor from valve base by removing the four (4) #8 screws�
b) Inspect the water diaphragm assembly to see if bypass hole in diaphragm is blocked� Remove
any debris by blowing on diaphragm or using compressed air� DO NOT use any tool (such as
a straight pin) to remove any debris� Enlarging the hole will shorten the valve cycling, cause
erratic behavior, and possibly shorten the life of the valve�
c) Inspect seating area on valve base to make sure no debris, pitting, or scoring is present� Clean
seat as necessary�
d) Inspect seating area on diaphragm for debris and clean as necessary� If debris has caused
permanent indentations in the rubber, it may have to be replaced�
e) Check the rubber bumper on the end of the solenoid armature for any debris, marks,
indentations, scratches, or deformations� Replacement may be necessary�
f) Ensure that the armature spring is in place and not missing�
g) Using the exploded view provided with this manual, reassemble the valve and test it's operation
to determine if the problem has been xed.
