IMPORTANT

Make sure that water supply is completely

off before installation is begun.

When drilling into tile, masonry, or other

hard materials to install wall and floor

anchors, be sure to wear safety goggles to

prevent eye injuries.

Wall anchors used must have a minimum

pull-out rating of 1,000 lbs.

The Sentry Washfountain requires a water

flowing pressure of at least 20 PSI, but no

greater than 80 PSI.

Step 3: Complete the Installation

1. Turn on the water to test the Washfountain.

2. Check to make sure both stop valves are fully open.

3. Push each push button/foot button to purge air from the lines.

Step 4: Adjust Air Metering Valve (Hand-operated pushbutton only)

NOTE: 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 dirt build-up on the timer. The air valve timing can be adjusting from

0–45 seconds.

1. Adjust the metering timing, if necessary, as outlined below:

• Unscrew the timer cover and use a screwdriver to tighten or loosen the timer (Figure 4).

Turning the timer clockwise increases the time; turning the timer counterclockwise decreases

the time. Be careful not to overtighten as the timer seat can be damaged.

• Continue to adjust until the timer is set at desired length.

• Replace the timer cover over the timer.

NOTE: The Vernatherm™ TMV valve is NOT factory preset. Upon installation, the temperature of

this valve must be checked and adjusted to ensure delivery of a safe water temperature. Water in

excess of 110°F (43°C) may cause scalding.

2. Check the temperature when approximately 1.0 GPM (2 wash stations) 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, follow the procedure below:

• Loosen temperature locking nut with wrench.

• Using a blade screwdriver, turn the adjustment stem counterclockwise to increase the

temperature or clockwise to decrease the temperature (Figure 5).

• Once desired temperature is reached, tighten nut to prevent temperature change.

3. Refasten the access panel with the screws supplied.

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

Fingerprints 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.

Troubleshooting Air Valve Metering Hand Control (AST4)

CAUTION: Turn off water supplies to unit before troubleshooting.

Problem: One or more individual operating stations fail to turn on.

Cause: Incoming water pressure is over 80 PSIG.

Solution: Reduce water pressure to below 80 PSIG.

Install a pressure-reducing valve at the building main set to the manufacturer's recommendations.

Lower line pressure will improve the performance and extend the life of all the plumbing in the

building.

Problem: An individual operating station fails to turn on.

Cause: A failed diaphragm/magnet assembly.

Solution: Test the station to determine cause.

1. Unscrew the valve clamp nut on the top of the valve (see Figure 11a on Page 22).

2. Remove valve cover. If the diaphragm/magnet assembly comes out with the cover, gently peel

the diaphragm away form the cover, taking care not to damage the diaphragm. Inspect the

diaphragm for any holes of tears. A damaged diaphragm needs to be replaced.

3. Insert the diaphragm/magnet assembly back into the valve, but leave the cover off.

4. Gently press the diaphragm until it is fully depressed. The valve should activate. If not, the

diaphragm/magnet assembly needs to be replaced.

Problem: One or more individual operating stations turn off too quickly or run too long.

Cause: Timing requires adjustment.

Solution: Readjust timing (see Page 12, step 4).

Problem: An individual operating station cannot be adjusted to run for more than five seconds.

Cause: Air tube connection leak.

Solution: Check 1/8" tubing connection.

1. Tighten compression nut at 1/8" tubing connection to air valve in pedestal.

2. If leak persists, remove the sprayhead cover and check the 1/8" elbow tube connection behind

the pushbutton assembly. Make sure the screw holding the elbow is tight and the fitting in the

elbow is firmly hand tightened. Make sure the tubing is pushed firmly into the fitting.

3. If leak persists, reseat the 1/8" tubing. Disconnect the tubing from the fitting by pressing down

on the plastic ring at the top of the fitting while firmly pulling the tubing out of the fitting. Trim

½" off the end of the tubing squarely with a razor-sharp knife and push the tubing firmly back

into the connector to make sure it is seated.

4. If the leak still persists, loosen the compression nut on the air valve inside the pedestal and pull

the tubing out of the fitting. Trim ½" off the end of the tubing squarely, with a razor-sharp knife.

Then slide the tubing through the nut until ½" of tubing is exposed. Insert tubing into the

compression fitting on the valve body and hand tighten the compression nut.

Troubleshooting Air Valve Metering Hand Control (AST4)

....Continued

Problem: An individual operating station won't turn off and drips.

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

Solution: Remove debris between the diaphragm and valve seat.

1. Remove the three Phillips-head screws that hold the air valve together. Be careful not to lose the

armature or spring (see Figure 11a on Page 22).

2. Remove the diaphragm. Remove any debris trapped between the diaphragm and the valve seat.

3. Rinse off the diaphragm and inspect for damage. Make sure the center orifice and the two small

side orifices are open.

4. Reassemble in reverse order, being careful not to over tightening the Phillips-head screws or you

may crack the plastic valve body. Tighten until the armature plate makes contact with the plastic

body.

Problem: An individual station will not shut off.

Cause: Timing mechanism is clogged.

Solution: Clear the timing mechanism.

1. If the timer cover has been sprayed with water, wait at least two minutes. It will shut off and

return to normal operation once it dries off.

2. If it doesn't turn off remove the timer cover. If the valve shuts off the cover is clogged and needs

to be replaced.

3. If the valve still doesn't turn off, turn the adjusting screw counter clockwise until it can be

removed from the valve body.

4. Wipe adjusting screw thoroughly with a lint-free towel making sure that there is no water or

debris on the adjusting screw.

5. Use a pipe stem cleaner to wipe the inside of the timer body if possible.

6. Replace timer-screw and adjust valve timing.

7. Replace timer cover.
