Installation Instructions
Cleaning and Maintenance Instructions
IMPORTANT: Strong alkaline or acid-based chemicals and cleansers should not be
used to clean the Crescent®. If these chemicals come in contact with
the Terreon® surface, wipe off the surface immediately and flush with
soapy water.
Terreon® and trap cover maintenance
The bowl and top cover are made of Terreon®, a densified solid surface material composed of an
acrylic modified polyester resin. Terreon® is resistant to chemicals, stains, burns and impact. Surface
damage can easily be repairable with everyday cleaners or fine grit abrasives. The trap cover is made
of vacuum-formed ABS plastic and will not chip, peel or flake. With regular cleaning, your Express®
Crescent® will provide years of dependable service.
Trap cover cleaning
IMPORTANT: Do not use abrasive cleansers to clean the trap cover. Abrasive
cleaners can mar the surface.
• Daily cleaning: Wipe the trap cover with a wet cloth, then rinse with water and wipe dry.
• Weekly cleaning: Give the trap cover a thorough cleaning with a liquid tub and tile cleaner to
remove soil and maintain the glossy finish.
• Graffiti/Vandalism: If vandals create markings on the trap cover,
Bradley recommends using Motsenbocker’s LIFT OFF® to remove
ink and spray paint. Remover #3 is for ink and markers, and Remover
#4 is for spray paint. Motsenbocker’s LIFT OFF® can be ordered
through Sanitary Maintenance Service, Inc. (call 1-800-451-5523, ext.
information). After cleaning with LIFT OFF®, give the trap cover a
final thorough cleaning with a liquid tub and tile cleaner to remove
soil and maintain the glossy finish.
Bowl and cover cleaning
• Daily cleaning: Wipe the unit with a damp cloth and then 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 with either an abrasive cleaner or by buffing
with a #7448 Scotch-Brite™ pad.
• Repair kit: In the unlikely event your Terreon® surface becomes damaged, it can easily and
inexpensively be repaired. Contact your Bradley representative to order a repair kit and be sure
to specify color when ordering.
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.
NOTE: It is emphasized that all products should be used in strict accordance with package instructions.

Solenoid Valve Troubleshooting
CAUTION: Turn off water supplies to unit before troubleshooting.
Problem:
Cause:
Solution:
An individual operating station fails to shut off and drips.
There is debris trapped between the diaphragm and the valve seat.
Remove debris between diaphragm and the valve seat.
1. Remove the three #8 Phillips-head screws that hold the solenoid valve assembly together. Be
careful not to lose the armature or spring (see Figure 8 on page 12).
2. Remove the diaphragm. Remove any particles that have been 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.
3. Reassemble in reverse order, being careful not to overtighten the Phillips-head screws or you
may crack the plastic valve body. Tighten until the armature plate makes contact with the plastic
body.
4. Reconnect the wiring per diagram on page 7 (for CRS-2/IR) or page 8 (for CRS-3/IR).
Problem:
Cause:
Solution:
An individual operating station fails to turn on.
A failed coil for the valve or loose electrical connection to the terminal.
Test the station to determine cause.
1. Disconnect the wires from the coil of an adjacent valve. Disconnect the wires from the problem
valve and reconnect to the adjacent valve.
2. Turn on electrical and water supplies to the unit. Pass your hand in front of the sensor of the
problem station, and the adjacent station should turn on.
If the adjacent station turns on and cycles normally, replace the coil on the problem valve.
If the adjacent valve fails to turn on, inspect the wires from the sensor cable and do the following:
• make sure there are no breaks and that the fully insulated disconnect terminals are firmly
crimped in place;
• turn off the electrical and water supplies;
• reconnect to the adjacent valve and turn on the water supplies to the unit;
• pass your hand in front of the sensor. If the station still fails to turn on, replace the sensor.

Thermostatic Mixing Valve 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 cross-
connections 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. Remove and clean strainer (see Figure 9 or 10 on page 14). If strainer needs to be replaced, order
Bradley part number 173-028.
2. 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 9 on Page 14).
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 (part number 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.
