Cleaning and Maintenance Instructions
IMPORTANT: Strong alkaline or acid-based chemicals and cleansers should not be
used to clean Terreon®. If these chemicals come in contact with the Terreon® surface,
wipe off the surface immediately and flush with soapy water.
Terreon® and panel maintenance
The bowl and sprayhead cover are constructed of Terreon®, a densified solid surface material
composed of an acrylic modified polyester resin. Terreon® is resistant to chemicals, stains, burns
and impact. Surface damage can be easily repaired with everyday cleaners or fine grit abrasives.
The panel and sprayhead body are made of an acrylic/ABS laminate, and will not chip, peel or
flake. With regular cleaning, your Terreon® fixture will provide years of dependable service.
Cleaning
• Daily Cleaning: Wipe the surface with a damp cloth and wipe dry.
• Weekly Cleaning: Wipe the surface with a damp cloth and a household liquid detergent.
Stubborn stains can be removed as follows:
1. Using a #7448 Scotch-Brite® pad, scrub with an abrasive cleanser such as Ajax®,
Comet® or Soft Scrub® and water.
2. Clean thoroughly with soapy water and allow to dry.
• Scorch Marks: Although Terreon® will not burn, a lit cigarette in contact with Terreon®
could leave a scorch mark. Scorch marks can be removed by buffing with a #7448 Scotch-
Brite pad or with an abrasive cleaner.
•Repair kit: In the unlikely event your Terreon® surface becomes damaged, it can easily and
inexpensively be repaired. Contact your Bradley representative to order a repair kit and be
sure to specify color when ordering.
Panel cleaning
IMPORTANT: Do not use abrasive cleansers to clean the panel or sprayhead body.
Abrasive cleaners can mar the surface.
•Graffiti/Vandalism: If vandals create markings on the panel, Bradley recommends using
Motsenbocker’s LIFT OFF® to remove ink and spray paint. Remover #3 is for ink and markers,
and Remover #4 is for spray paint. Motsenbocker’s LIFT OFF® can be ordered through
Sanitary Maintenance Service Inc. (call 1-800-451-5523 x 425 or visit
www.santitarymaintenance.com/product.htm for ordering information). After cleaning with
LIFT OFF®, give the panel a final thorough cleaning with a liquid tub and tile cleaner to
remove soil and maintain the glossy finish.
NOTE: 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.

Soap Dispenser Maintenance
Step 1: Fill soap dispensers
The two soap valves will dispense vegetable/coconut oil liquid soaps, synthetic detergents, vis-
cous lotion soaps, and antiseptic solutions. A 10-15% concentration is recommended for vege-
table or coconut oil liquid soaps. Synthetic detergents, lotion soaps, and antiseptic soaps require
no dilution.
1. Using two screwdrivers (or similar tool), push up on the release tabs located beneath each
soap dispenser and pull out the soap tanks from the sprayhead (see Figure 8a).
2. To remove packing dust, rinse out each soap tank with hot water. Shake water out thoroughly
and allow to dry.
3. Pour the soap into each soap tank's filler hole (see Figure 8b).
4. After each soap tank is filled, position the soap tanks into the sprayhead openings and push into
place.

Soap Dispenser Maintenance continued . . .
Step 2: Change soap type
1. Pour out all of the soap from the dispenser.
2. Rinse the soap dispenser with hot water several times until all of the residue is removed, and
pump the valve until clean water appears.
3. Rinse the dispenser with ethyl alcohol and allow to air dry.
4. After the dispenser is dry, pour the new soap into the soap dispenser.
Step 3: Cleaning Instructions
Regular cleaning of the soap dispenser is recommended to ensure optimum performance and
maximum service life. Cleaning the soap dispenser monthly to remove soap residue, dirt, and
other accumulations should become a regular part of your washroom cleaning routine and general
maintenance program.
IMPORTANT: Do not use abrasive cleansers to clean the soap tank. Abrasive
cleaners can mar the surface.
Clean exterior: Use warm water and soap to clean the exterior of the soap dispenser. Dry with
a soft cloth.
Clean interior: Inspect the interior of the soap tank for residue or coagulation of soap. If
necessary, clean the soap tank according to the following procedure:
1. Pour out any remaining soap in the tank.
2. Fill the tank half-full of hot water and shake the tank to dislodge the soap residue.
3. Empty the water from the container and repeat steps 1 and 2 until the soap container is clean.
NOTE: If rinsing alone does not remove the soap residue, place a small chain (24 inches long)
into the soap tank with hot water and shake the container until the chain dislodges the residue.
Then remove the chain and rinse out the soap tank.
Clean internal components: To clean the internal components of the soap dispenser, pump
hot water through the soap dispenser until a clean flow of water comes out of the valve.
Check Valve Troubleshooting
If water just dribbles or does not flow from sprayhead:
1. Close the stops and check the valves that supply water to the lavatory system.
2 Inspect the stop/check valves for proper installation.
3. Remove the flexible hoses from the stop/check valves and clean the strainers, if necessary.
If water sprayhead delivers all hot or cold water:
1. Close the stops and check the valves that supply water to the lavatory system.
2. Inspect the stop/check valves for proper installation.
3. Remove the flexible hoses from the stop/check valves and clean the strainers, if necessary.
4. Inspect mixing valve for proper installation (see Vernatherm valve on page 19).
• A red marking indicates the hot inlet.

Vernatherm™ Mixing Valve Maintenance and Service
*Repair kit S45-049 is pre-packaged and includes O-Ring, Flip Ring, Power Element and Spring.
Maintenance Instructions
1. Disassemble the Vernatherm™ Valve as shown,
being careful not to damage the power element.
Replace the element, if necessary.
2. If necessary, remove the old flip ring and replace
with a new ring.
NOTE: An old or worn flip ring may cause temperature
fluctuation and/or water chatter.
3. Reassemble the power element and valve body.
Apply grease to the main valve slide and gently
ease into position, rotating so that grease is
applied to the flip ring. Do not force the slide as
this may push the flip ring from its position. To
test, rotate the slide; a slight drag should be felt
when correctly installed.
4. Reassemble the valve.
Service Suggestions
When servicing the valve, make sure it is installed in the correct position. The most common error
occurs when the valve is installed in the reversed position, that is, the hot line is connected to the
cold line and the cold is connected to the hot.
NOTE: A red marking indicates the hot side of the valve.
The table below lists conditions that occur when the valve is installed correctly, and when it is in
the reversed position.
