Pre-Installation Information

Terreon

material

The Quadra-Fount® features Terreon

, a durable solid surface material used on the bowl and

pedestal. Terreon

resists stains, burns and impact, and is repairable with everyday cleaners or fine-

grit abrasives.

Touch Time and solenoid valve

Each Touch Time pushbutton activates a flow of water. Each nozzle is controlled by a separate

solenoid valve, allowing each user to activate a flow of tempered water from one spray nozzle with a

pushbutton for 15 seconds. Each valve uses less than half the maximum amount of hot water allowed

by the ANSI/ASHRAE/IES 90A-1980 Standard.

Solenoid valve: An electronically controlled solenoid valve serves as the metering mechanism. Few

moving parts provide reliable metering performance and the solenoid is unaffected by chemicals and

minerals often present in municipal water supplies.

Barrier-free and ADA compliant

The Terreon® Quadra-Fount® with Touch Time is designed to comply with all ADA guidelines on

reaches, clearances and operation when mounted at standard height dimensions by the installer (see

page 4 of this instruction manual for rough-in and mounting dimensions).

Cleaning and Maintenance Instructions 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

Finger Prints 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.

Solenoid Valve Troubleshooting

CAUTION: Turn off water supplies to unit before troubleshooting.

Problem: An individual operating station fails to shut off and drips.

Cause: There is debris trapped between the diaphragm and the valve seat.

Solution: 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 11 on page 14).

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 9.

Problem: An individual operating station fails to turn on.

Cause: A failed coil for the valve or loose electrical connection to the terminal.

Solution: 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. Depress the Touch Time pushbutton of the

problem station, 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;

• depress the Touch Time pushbutton. 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. 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 12 on 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.
