Cleaning and Maintenance Instructions
IMPORTANT: Strong alkaline or acid-based chemicals and cleansers should not be used to clean
the MG-3/BIR3 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 MG-3/BIR3 Express® will
provide years of dependable service.
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.
Terreon® Bowl, Sprayhead and Pedestal End Cap cleaning
IMPORTANT: To sustain original finish, additional care is recommended for dark colored solid
surfaces to maintain highest quality color. The original luster can be maintained by
periodically applying furniture polish, mineral oil or a solid surface cleaner or polish.
For more information on restoring dark colors, see Bradley document #1505. Length
of time between applications varies with usage.

Troubleshooting BIR3 Components
CAUTION: Turn off water supplies to unit before troubleshooting.
Problem: An individual operating station drips and fails to shut off.
Cause: There is debris trapped between the diaphragm and the valve seat.
Solution: Remove debris between diaphragm and the valve seat.
Disconnect the plug from the battery 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 (see Figure 13
on page 17). 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 overtighten the Phillips-head screws or you may crack the
plastic valve body. Tighten until the armature plate makes contact with the plastic body. Reconnect the battery plug
per diagram on page 11. Turn on water supplies to the unit.
Problem: An individual operating station fails to turn on or off.
Cause: A dead or faulty battery.
Solution: Test the station to determine cause and replace battery if required.
Disconnect the plug from the battery to the circuit board of the problem valve. Disconnect the plug from the battery
to the circuit board of an adjacent valve. Connect the battery 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 the station
turns on, and cycles normally, replace the battery.
Cause: Faulty sensor eyes.
Solution: Test station to determine cause; replace sensor eyes if
required.
Figure 11a
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 the station turns on and cycles normally, replace the sensor eyes.
Cause: Faulty solenoid valve.
Solution: Test station to determine cause; replace solenoid valve if
required.
Remove the screw, circuit board and standoff from the problem valve.
Remove the battery holder. With a good working battery, briefly contact the
solenoid valve directly with the battery as shown in Figure 12a. The contact
should cause the valve to open. With the battery holder removed, briefly
contact the solenoid valve with the battery in the position shown in Figure
12b. This should cause the valve to close. If the valve does not operate when
directly contacted with a good battery, and the solenoid valve has already
been cleaned as outlined at the beginning of this troubleshooting section,
replace the solenoid valve.
If problems persist:
Pass your hand in front of the problem station, while at the same time looking
to see if the indicator light on the circuit board flashes (the indicator light is
located near the hole in the circuit board where the standoff is mounted). If
it does not flash, and the battery and sensor eyes have already been tested
as outlined above, the problem may be with the circuit board. Make a
note of the numbers printed on the circuit board, then contact your Bradley
representative for assistance.
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.
