Cleaning and Maintenance for Terrazzo
Please refer to Bradley document #9901 for Terrazzo care and maintenance.
Cleaning and Maintenance for Stainless Steel
Material Description: Stainless steel is extremely durable, and maintenance is simple and inexpensive.
Proper care, particularly under corrosive conditions, is essential. Always start with the simplest solution and
work your way toward the more complicated.
Routine cleaning: Daily or as often as needed use a solution of warm water and soap, detergent, or ammonia.
Apply the cleaning solution per the manufactures instructions and always use a soft cloth or sponge to avoid
damaging the finish.
Stubborn Stains: To remove stains from stainless steel use a stainless steel cleaner and polish such as Ball®
stainless steel cleaner or a soft abrasive. Always follow the manufactures instructions and apply in the same
direction as the polish lines.
IMPORTANT: NEVER USE ORDINARY STEEL WOOL OR STEEL BRUSHES ON
STAINLESS STEEL. ALWAYS USE STAINLESS STEEL WOOL OR
STAINLESS STEEL BRUSHES.
Special Situations for Material
Fingerprints and Smears: To remove fingerprints or smears use a high quality stainless steel cleaner and
polish in accordance with the manufactures instructions. Many of these products leave a protective coating the
helps prevent future smears and fingerprints.
Grease and Oil : To remove grease and oil use a quality commercial detergent or caustic cleaner. Apply in
accordance to the manufactures instructions and in the direction of the polish lines.
Precautions: Avoid prolonged contact with chlorides (bleaches, salts), bromides (sanitizing agents),
thiocyanates (pesticides, photography chemicals, and some foods), and iodides on stainless steel equipment,
especially if acid conditions exist.
IMPORTANT: 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
actual 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.
Brand Names: 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.

Metering Air Valve Troubleshooting
Problem: Valve will not shut off.
Cause: Timing mechanism is clogged.
Solution: Clean and inspect timing mechanism:
1. If compressed air is available, blow water and debris from timer cover of timing mechanism.
2. Turn adjusting screw out all the way. Clean and inspect screw and valve body.
3. Turn adjusting screw in to desired cycle time.
Problem: Valve will not turn on.
Cause: Water is not being supplied to unit.
Solution: Open all stops on mixing valve.
Cause: Water pressure is over 80 PSI.
Solution: Install a pressure reducing valve.
Cause: Failed diaphragm/magnet assembly.
Solution: Unscrew the valve clamp nut on valve. Remove valve cover. Gently press the the
diaphragm. The valve should activate. If not, replace the diaphragm/magnet assembly.
Problem: Timing can not be adjusted for more than 5 seconds.
Cause: There is an air leak
Solution: Check the valve assembly:
1. Check all tubing and fittings for proper assembly.
2. Tighten cap and nut on 1/8" tubing.
Problem: Push button does not work properly.
Cause: Air volume may not be sufficient to operate valve.
Solution: Check for leaks and lubricate U-cup:
1. Check all fittings for air leaks.
Problem: Water is dripping from the streamformers.
Cause: Debris has accumulated on valve seat or orifices.
Solution: Clean and inspect valve seat.
1. Remove screws and disassemble metering valve.
2. Clean valve seat and inspect for deep gouges or scratches. Replace valve body if necessary.
3. Remove any debris clogging off-center hole in rubber diaphragm.

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. If strainer needs to be replaced, order Bradley part no. 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 page 16).
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.

3Install Pedestal, Wall and Floor Anchors
Before mounting the pedestal to the floor, make sure the floor is level. If
necessary, install shims under the left and/or right pedestal. Remove molding
strips or tiles that could prevent a flush mounting to the wall.
AMeasure and mark the centerline of the
washfountain on the wall and floor. Align
the locating notches on the mounting
panel with the centerline.
Do not leave the bowl on the pedestal
unsupported, as it may fall and cause
personal injury or damage to property.
