4. Align the valve bracket mounting screws with slots on the frame. Let the valve bracket slide down to
lock into place.
NOTE: Optional Battery Power Pack (p/n S65-284) for quickstart power-up is available from Bradley.
IMPORTANT: The Vernatherm™ valve is NOT factory-preset. Upon installation, the valve
temperature must be checked and adjusted to ensure delivery of safe water
temperature. Water in excess of 110°F (43°C) may cause scalding.
5. Check the temperature when approximately1.0 GPM water flow is reached and adjust if necessary
(the range of the valve is 95°F–115°F (35°C–43°C). To adjust the temperature, first loosen the
temperature locking nut with a wrench. Then using a blade screwdriver, turn the adjustment stem
counterclockwise to increase the temperature or clockwise to decrease the temperature. Once
desired temperature is reached, tighten the nut to prevent temperature change.
6. After testing is complete, reinstall access panel to frame. Fasten access panel with the six panel
screws and washers provided (Figure 3, page 8).

Cleaning and Maintenance Instructions
IMPORTANT:
Strong alkaline or acid-based chemicals and cleansers should not be used
to clean the Express®. If these chemicals come in contact with the Terreon®
surface, wipe off the surface immediately and flush with soapy water. Avoid
unnecessary or prolonged contact with hot pans and objects.
Terreon® and panel maintenance
The bowl, sprayhead and pedestal end caps are made of Terreon®, a solid cast polyester resin
material. Terreon® resists chemicals, stains, burns and impact, and is repairable with everyday
cleaners or fine-grit abrasives. The panel is made of stainless steel. With regular cleaning, your
Terreon® fixture will provide years of dependable service.
Terreon® Bowl, Sprayhead and Pedestal End Cap cleaning
• Daily Cleaning: Wipe the surface with a damp cloth and wipe dry.
• Weekly Cleaning: Wipe the surface with a damp cloth and a household liquid detergent.
Stubborn stains can be removed as follows:
1. Using a #7448 Scotch-Brite® pad, scrub with an abrasive cleanser such as Ajax®,
Comet® or Soft Scrub® and water.
2. Clean thoroughly with soapy water and allow to dry.
• Scorch Marks: Although Terreon® will not burn, a lit cigarette in contact with Terreon® could
leave a scorch mark. Scorch marks can be removed by buffing with a #7448 Scotch-Brite pad or
with an abrasive cleaner.
• Repair kit: In the unlikely event your Terreon® surface becomes damaged, it can easily be
repaired. Contact your Bradley representative to order a repair kit and be sure to specify color
when ordering.
Stainless Steel Access Panel cleaning
Stainless steel is extremely durable, and maintenance is simple and inexpensive. Proper care,
particularly under corrosive conditions, is essential. Ordinary deposits of dirt and grease are quickly
removed with soap and water. Whenever possible, the metal should be thoroughly rinsed and dried
after washing. To remove tightly adhering deposits, use stainless steel polishing powder. In all cases,
rub in the direction of the stainless steel grain.
IMPORTANT:
Never use ordinary steel wool or steel brushes on stainless steel. Always
use stainless steel wool or stainless steel brushes.
Avoid prolonged contact with chlorides, bromides, thiocyanates, and iodides on stainless steel
equipment, especially if acid conditions exist. Do not permit salty solutions to evaporate and dry on
stainless steel. The appearance of rust streaks on stainless steel leads to the belief that the stainless
steel is rusting. Look for the source of the rust in some iron or steel particles which may be touching,
but not actually a part of the stainless steel structure.
NOTE: Strongly acidic or caustic cleaners may attack the steel causing a reddish film to appear. The
use of these cleaners should be avoided.
NOTE: Use of brand names is intended only to indicate a type of cleaner. This does not constitute an
endorsement, nor does the omission of any brand name cleaner imply its inadequacy. Many products
named are regional in distribution and can be found in local supermarkets, department and hardware
stores or through your cleaning service. It is emphasized that all products should be used in strict
accordance with package instructions.

Troubleshooting NDT Components
IMPORTANT: ndite™ technology requires a minimum of 400 LUX to operate. Before
proceeding make sure all of the lights in the room are operating and
that there are no obstructions blocking the light hitting the surface of
the sprayhead. If available, use a light meter to measure the amount
of light on the surface of the Lavatory System sprayhead. Also check
for severe vandalism or other physical damage to the sprayhead.
Leave the lights in the room on for aproximately four hours to fully
charge the system before operating.
NOTE: If there is inadequate lighting in the location where the unit is installed, add additional lighting
or convert the system to battery power. Contact Bradley and order Battery Pack Kit S45-2083 (one per
station).
NOTE: Refer to Figure 11 (solenoid valve) on page 20 when necessary.
Problem:
Cause:
Solution:
Water will not shut off.
Water pressure is too low.
Test for proper water pressure.
The Express Lavatory System operating specifications require a water pressure of between 20- 80 PSI at
the connection to the fixture. If the pressure is above 80 PSI the valve may not operate. When verifying
water pressure always use a reliable pressure gauge at the connection to the fixture.
Cause:
Solution:
Faulty solenoid valve.
Test station; replace solenoid valve if required.
Disconnect the plug from the power management module to the circuit board of the problem valve.
Remove the three #8 Phillips-head screws that hold the solenoid valve assembly together. Be careful not
to lose the armature or spring. Remove the diaphragm. Remove any particles that are trapped between
the diaphragm and the valve seat. Rinse off the diaphragm and inspect for damage. Make sure the center
orifice and both small side orifices are open. Reassemble in reverse order, being careful not to over
tighten the Phillips-head screws or the plastic valve body may crack. Tighten until the armature plate
makes contact with the plastic body. Reconnect the power plug. Turn on water supply to the unit.
Problem:
Cause:
Solution:
Water in multiple stations will not activate.
Inadequate lighting.
Test for adequate lighting.
ndite technology requires a minimum of 400 LUX to operate. Before proceeding make sure all of the
lights in the room are operating and that there are no obstructions blocking the light hitting the surface of
the sprayhead. If available, use a light meter to measure the amount of light on the surface of the
lavatory system sprayhead. Also check for severe vandalism or other physical damage to the sprayhead.
If there is inadequate lighting available in the location where the unit is installed, add additional lighting.
If additional lighting is unavailable, the system may be converted to battery power. Contact Bradley and
order Battery Pack Kit S45-2083 (one per station)
Cause:
Solution:
Improper water pressure.
Test for proper water pressure.
The Express Lavatory System operating specifications require a water pressure of between 20- 80 PSI at
the connection to the fixture. If the pressure is above 80 PSI the valve may not operate. When verifying
water pressure always use a reliable pressure gauge at the connection to the fixture. If water pressure is
high but not above 80 PSI the following may be raising the pressure: circulation system , booster pumps
orundersized or no expansion tank. If any of this equipment is raising the pressure above the specified
pressure levels it will be characterized by the system working for a short time after the supply
connections are made and then stopping.

Problem:
Cause:
Solution:
Water in multiple stations will not activate.
No power to the sensor board.
Check for power to the sensor board.
Remove the front cover from the fixture. Wave your hand in front of the sensor window, one station at a
time, while looking at the sensor boards below the fixture. A light should flash on the sensor board when
each station is activated. If no light flashes, test the output from the photovoltaic cells with a multimeter
(available from most home improvement stores and professional supply distributors).
Cause:
Solution:
Improper output from voltaic cells.
Test output from photovoltaic cells.
Test the output from the photovoltaic cells with a multimeter (available from most home improvement
stores and professional supply distributors).
NOTE: The electrical system on ndite™ powered Express® Lavatory Systems is low voltage and low
amperage.
With the room lighting on, unplug the cord running from the photovoltaic cells to the power management
module. Touch the red multimeter probe to the inside of the plug and the black multimeter probe to the
outside of the plug. With the Multimeter in the DC Volts setting, it should have a reading of 6 volts or
more. If the reading is under 6 volts, doublecheck the room lighting levels. If the reading is over 6 volts
and the system will not operate, replace the ndite power management module.
Problem:
Cause:
Solution:
Water in one station will not activate
Faulty sensor eyes.
Test sensor eyes and replace, if necessary.
Disconnect the sensor cable from the circuit board of the problem valve. Disconnect the sensor cable
from the circuit board of an adjacent working valve. Connect the sensor cable from the adjacent working
valve to the problem valve. Activate the problem station’s sensor. The station should turn on. If it turns
on and cycles normally, replace the eyes in the problem station.
Cause:
Solution:
Problem with control boards.
Test the control boards and replace the battery, if necessary.
Disconnect the plug from the power supply to the circuit board of the problem valve. Disconnect the
plug from the power supply to the circuit board of a working adjacent valve. Connect the power plug
from the adjacent working valve to the problem valve. Wait for ten seconds. Activate the problem
station’s sensor ten times. The station should turn on. If it turns on, and cycles normally, replace the
batteries in the problem station.

Thermostatic Mixing Valve Maintenance and Troubleshooting
NOTE: Before attempting to troubleshoot the valve or disassemble the components, check for the
following conditions:
• If stop/check valves are used, make sure that they are fully open.
• Make sure that the hot and cold inlet pipes are connected properly, and that there are no crossconnections or leaking stop/check valves.
• Check the hot water heater output to make sure that it is at least 20° F above the set
temperature.
Be sure to close the appropriate shut-off valves prior to disassembly of the valve and reopen the
valves after inspection and repair is complete.
Problem: Limited water flow.
Cause: Dirt and debris have built up in the valve or strainer.
1. Check to make sure both hot and cold supplies are connected to the Vernatherm mixing valve and
that they have water flow.
2. Remove and clean strainer (see Figure 12 or 13 on page 22). If strainer needs to be replaced,
order Bradley part no. 173-028.
3. Check the piston for smooth movement.
To check the valve's piston for free and smooth movement, follow the procedures outlined below:
1. Remove the valve's cap and thermostat (see Figure 12 on Page 22).
2. Push down on the piston with your finger (the piston should move freely). If the movement is not
as it should be, the piston needs to be cleaned. Follow the method outlined below for cleaning the
piston and valve body:
• Remove the thermostat.
• Lift the piston out with a needle-nose pliers and remove the spring.
• Any cleaner suitable for brass and stainless steel may be used (if cleaning with suitable cleaner
is not sufficient to remove debris, a 400-grit sandpaper may be used to polish and hone the
piston and valve body).
• Snap spring into piston (will detent) and reassemble into the valve body. Retest the piston.
3. If, after a thorough cleaning, the piston does not move freely, the piston must be replaced. Contact
your Bradley representative and ask for Repair Kit (part number S65-259).
Problem: External leaks in the system.
Cause: O-rings have been damaged.
Solution: Replace O-rings where necessary.
For replacement of the O-rings, contact your Bradley representative and ask for Repair Kit S65-259.
Problem: Improper water temperature or temperature fluctuation.
Cause: Thermostat is slowly failing or not working at all.
Solution: Check the thermostat for proper operation.
1. At room temperature (80° F or less) remove cap and thermostat.
2. Place thermostat into container with 115° F water. The pushrod should pop out of the
thermostat approximately 1/10".
3. If thermostat pushrod does not pop out, the thermostat must be replaced. Contact your Bradley
representative and ask for Repair Kit (part number S65-259).
Cause: Valve temperature is not properly set
Solution: Adjust the temperature.
Using a blade screwdriver, turn the adjustment stem counterclockwise to increase the temperature or
clockwise to decrease the temperature.
