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: Water will not shut off.
Cause: Water pressure is too low.
Solution: 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: Faulty solenoid valve.
Solution: 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: Water in multiple stations will not activate.
Cause: Inadequate lighting.
Solution: 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,

Cause: Improper water pressure.
Solution: 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, or undersized 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: Water in multiple stations will not activate.
Cause: No power to the sensor board.
Solution: 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: Improper output from voltaic cells.
Solution: Test output from photovoltaic cells.

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: Water in one station will not activate
Cause: Faulty sensor eyes.
Solution: 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: Problem with control boards.
Solution: 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.
