Infrared (IR) — Sensor and Solenoid Valve Troubleshooting
If a station is not functioning properly it is most likely either the solenoid valve or the sensor.
Troubleshooting multi station units is fairly easy, as you can swap parts (actually just by changing the wires) and use the process of elimination to figure out which of the 2 parts is causing the problem.
How the system operates:
1. The transformer sends 24 volts to the sensor.
2. The sensor acts only as a switch.
3. When hands go into the active field of the sensor, the sensor activates and sends a power signal on to the solenoid valve.
4. The power signal activates and opens the solenoid valve which allows the water to flow to the sprayhead. The solenoid valve stays open allowing water to flow as long as it is receiving a signal form the sensor (hands remain in the active field).
5. When hands are removed from the active field, the sensor turns off (note some models have a slight delay feature built-in.) and shuts off the power signal to the solenoid valve.
CAUTION: Turn off water supplies to unit before troubleshooting.
Problem Cause Solution
An individual operating station fails to shut off and drips.
An individual operating station fails to turn on.
There is debris trapped between the diaphragm and the valve seat.
A failed coil for the valve or loose electrical connection to the terminal.
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.
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 the appropriate diagram on next 4 pages.
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.
a. If the adjacent station turns on and cycles normally, replace the coil on the
b. If the adjacent valve fails to turn on, inspect the wires from the sensor cable
problem valve.
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.

Air Metering Valve Maintenance (Prior to May 2, 2005)
Adjust Air Valve Meter Time
The air valve timer is located next to the tube connector on the air valve body. The timer is capped with a filter to prevent build-up on the timer. The air valve timing can be adjusted from 0 to 45 seconds.
1. Remove filter cap and use a screwdriver to tighten or loosen the timer. Turning the timer clockwise increases the time; turning the timer counterclockwise decreases the time.
2. Continue to adjust until the timer is set at desired length.
3. Replace filter cap over the timer.
Tube Connection Leaks
1. Push in the white manual release button while pulling the tube out to disconnect the tube at the connector. No tools are needed.
2. To correct a leak, press tubing firmly into the connector and make sure it is seated.
3. If leak persists, remove tubing from the fitting and trim the tubing end square with a razor-sharp knife. If leak continutes, replace the fitting or contact your Bradley representative for assistance.

Thermostatic Mixing Valve Troubleshooting (Prior to February 1, 2013)
Before attempting to troubleshoot the valve or disassemble the components, check for the following conditions:
• If stop 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 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 Cause Solution
External leaks. Damaged O-rings. Replace O-rings where necessary. For replacement of the O-rings, contact
your Bradley representative and ask for Repair Kit (part number S65-259).
Improper water temperature or temperature fluctuation.
Limited water flow. Dirt and debris have built up in
Thermostat is slowly failing or not working at all.
Valve temperature is not properly set.
the valve or strainer.
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).
Adjust the temperature.
Check the valve's piston for free and smooth movement,
1. Remove the valve's cap and thermostat
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).

Care and Cleaning of Stainless Steel Sentry Washfountains
Stainless steel is extremely durable, and maintenance is simple and inexpensive. Proper care, particularly under corrosive conditions, is essential. Follow the cleaning instructions listed below:
• 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.
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 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.

Soap System
Soap Recommendations
Quality soap dispensers require good quality soap and periodic maintenance to properly operate. Bradley soap dispensers will provide dependable, consistent operation over the long term when soap with reasonable viscosity and pH levels are used and when a minimal amount of periodic maintenance is performed on the valves.
Soap thickness is determined by a measurement called viscosity. Soap viscosity should be between 100 cps (centerpoise) and 2500 cps for all Bradley soap dispensers. Thinner soaps are perceived by the users as being "watered down" so users tend to take more than they need, resulting in waste. Thick soaps flow slower and inhibit
the "flushing" action of the valves, which allows the soap to congeal in the valve and cause clogs.
The pH (acid) level of the soap should be in the range of 6.5 to 8.5. More acidic soaps (pH levels lower than 6.5) will corrode metal parts (even stainless steel!!) and degrade rubber and plastic components. They will also cause skin irritation. Most inexpensive soaps (typically the pink lotion type) fall into this acidic category and will eventually cause valve failure and metal corrosion. Base soaps (pH levels higher than 8.5) will cause swelling or degradation of rubber and plastic parts and skin irritation.
Generally, any quality soap meeting the viscosity and pH guidelines above will work well with Bradley soap dispensers. PCMX or Isapropanol based antibacterial soaps (within viscosity and pH limits) will also work with Bradley dispensers. Soaps satisfying these basic guidelines will provide consistent flow and reduce clogs.
Most soap dispenser problems are caused by soap that is too thick or corrosive, or by a lack of maintenance. Many soaps come in concentrate form which must be diluted with water. Often, the soap is improperly diluted or used straight out of the bottle, which causes clogging and valve failure. If proper soap is being used, valves that have never been cleaned are usually the source of dispensing problems. Bradley has entered into an agreement with Champion Brand Products to provide additional customer service for purchasers of our dispensers regarding soap issues. They are very helpful and can get to the bottom of almost any soap dispenser related problem. They also sell an excellent "Bradley approved" soap. Please see Soap Instruction Sheet 215-1286 for details about soap valve cleaning or how to contact Champion. With proper maintenance and soap, Bradley dispensers will provide long term, trouble free operation.
Soap Dispenser Maintenance Instructions for Sentry Washfountains
Bradley soap dispensers will provide dependable, consistent operation over the long term when the proper soap is used and when a minimal amount of periodic maintenance is performed on the valves. Valves must be maintained (cleaned) to function properly.
To ensure proper operation of your soap dispenser, follow these instructions:
• Once per month, remove the cap from the soap tank and insert the draw tube (below the cap) into hot water and soak it for 30 minutes.
• Push valve at least 20 times while it is soaking.
• Flush soap reservoir with hot water while valve is soaking.
In cases of extreme clogging, the valve should be disassembled and the parts should be soaked in hot water or cleaning solution to restore proper functioning. Soap dispensers that will not be used for extended periods of time (schools during summer break, etc.) should be drained, cleaned and left empty until put back into service. Soap left on the outside of dispensers can cause discoloration and corrosion of the reservoir (even on stainless steel units). All soap should be wiped or scrubbed off daily, then the outside of the dispenser should be rinsed with clear water and dried with a soft cloth.
