Installation Instructions continued . . .

Step 7: Connecting electrical and supply tubing

WARNING: The MG-2/BIR3 must be connected to the 6 VDC battery. Connection to 110

VAC may cause personal injury and/or damage to electronics. Connection of leads
other than shown may cause permanent sensor damage.

CAUTION: To avoid activating the sprayhead valve, make sure to connect the sensor

cable plugs to the circuit board before inserting the batteries into the battery holder.
If the cable is connected or disconnected while the batteries are installed, the station
will activate and continue running for 75 seconds.

1. Snap the sensor plugs from the sprayhead into the proper valve’s circuit board.

2. Insert the batteries into the battery holders (see Figure 7a). Mount the battery holders (with
batteries) in a convenient location on the frame using the hook-and-loop fastener provided.

3. Snap the battery holder plugs into the female circuit board plugs.

4. Insert the two sprayhead supply tubes
into the two solenoid tube connectors by
loosening the compression nut and
firmly pushing the tubing into the tube
connector until the tubes are fully
seated, then re-tighten the compression
nut by hand (see Figure 7b).

5. Align the valve bracket mounting screws
with slots on the frame. Let the valve bracket slide down to lock into place.

6. Turn on the water supply to the MG-2/BIR3 and check for leaks. Pass your hand in front of each
station’s sensor until all the air is purged from the lines and water is flowing smoothly.

IMPORTANT: The Vernatherm™ valve is NOT factory-preset. Upon installation, the valve

temperature must be checked and adjusted to ensure delivery of safe water
temperature. Water in excess of 110°F (43°C) may cause scalding.

7. Check the temperature when approximately1.0 GPM water flow is reached and adjust if
necessary (the range of the
valve is 95°F–115°F
(35°C–43°C). To adjust the
temperature, first loosen the
temperature locking nut with
a wrench. Then using a blade
screwdriver, turn the
adjustment stem
counterclockwise to increase
the temperature or clockwise
to decrease the temperature.
Once desired temperature is
reached, tighten the nut to
prevent temperature change.

8. After testing is complete,
reinstall access panel to
frame. Fasten access panel
with the five panel screws and washers provided (see Figure 3 on page 8).

Cleaning and Maintenance Instructions

IMPORTANT: Strong alkaline or acid-based chemicals and cleansers should not be

used to clean the MG-2/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 MG­2/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.

• For regular cleaning, use standard commercial or household products such as Formula 409® or
Windex®.

• Remove tough stains with Ajax®, Comet® or Soft-Scrub® and a green Scotch-Brite® pad or
lightly sand in a circular motion with 240 grit wet/dry sandpaper. The finish can be renewed with
a maroon Scotch-Brite® pad.

• Remove scratches with a green Scotch-Brite® pad. The finish can be renewed with a maroon
Scotch-Brite® pad. Remove hard water build-up with a mild solution of vinegar and water.

* Use of brand names is intended to indicate a type of cleaner and does not constitute an

endorsement.

** It is emphasized that all products should be used in strict accordance with package instructions.

• Repair kit: A repair kit is available from Bradley to repair/patch the Terreon® bowl and shelf.
Contact your Bradley representative to order a repair kit and be sure to specify color.

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.

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.

Thermostatic Mixing Valve Maintenance and 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 14 or 15 on page 19). 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 Figure 14 on Page 19).

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.
