1. For overhead supply lines, install 1/2"nominal copper supply tubing by passing the lines through the holes in the dispenser cover and then down through the support tube.
2. Install the valving assembly using suitable fittings to the supplies as shown in Figure 7 at the approximate height indicated in Table 3.
3. Slide the tailpiece nut over the tailpiece and connect the tailpiece to the supply pipe (or to the nipple/coupling for B or H drain).

Step 6: Installing the Operating Rod
1. Insert the operating rod in the operating rod lever and then into the foot lever (see Figure 8).
NOTE: For normal operation, use the operating rod as shipped. The spring loaded cartridge should be adjusted so there is no play in the operating lever. Care must be taken to insure that a snug fit is achieved without activating the foot valve or water will leak from the sprayhead (see Figure 8).
2. When movement of the operating rod is insufficient to open the foot valve, disassemble the rod and remove the spacer and override spring. Reassemble the operating rod as shown in Figure 9. Reinstall and adjust so that the foot valve is completely open when the foot lever is fully depressed. This prevents damage to the foot valve due to the absence of the override spring.
3. Turn supplies on and activate the sprayhead. Check piping installation for leaks.
4. Clean the sprayhead if necessary. See page 21 for sprayhead troubleshooting. Adjust the volume control valve, if necessary, to control the flow of water.

Soap Recommendations and Maintenance Tips
Quality soap dispensers require good quality soap and periodic maintenance to properly operate. Bradley soap dispensers will provide dependable, consistent operation over the long term when soap with reasonable viscosity and pH levels are used and when a minimal amount of periodic maintenance is performed on the valves.
Soap thickness is determined by a measurement called viscosity. Soap viscosity should be between 100 cps (centerpoise) and 2500 cps for all Bradley soap dispensers. Thinner soaps are perceived by the users as being “watered down” so users tend to take more than they need, resulting in waste. Thick soaps flow slower and
inhibit the “flushing” action of the valves, which allows the soap to congeal in the valve and cause clogs.
The pH (acid) level of the soap should be in the range of 6.5 to 8.5. More acidic soaps (pH levels lower than 6.5) will corrode metal parts (even stainless steel!!) and degrade rubber and plastic components. They will also cause skin irritation. Most inexpensive soaps (typically the pink lotion type) fall into this acidic category and will eventually cause valve failure and metal corrosion. Base soaps (pH levels higher than 8.5) will cause swelling or degradation of rubber and plastic parts and skin irritation.
Generally, any quality soap meeting the viscosity and pH guidelines above will work well with Bradley soap dispensers. PCMX or Isapropanol based antibacterial soaps (within viscosity and pH limits) will also work with Bradley dispensers. Soaps satisfying these basic guidelines will provide consistent flow and reduce clogs.
Most soap dispenser problems are caused by soap that is too thick or corrosive, or by a lack of maintenance. Many soaps come in concentrate form which must be diluted with water. Often, the soap is improperly diluted or used straight out of the bottle, which causes clogging and valve failure. If proper soap is being used, valves that have never been cleaned are usually the source of dispensing problems. Bradley has entered into an agreement with Champion Brand Products to provide additional customer service for purchasers of our dispensers regarding soap issues. They are very helpful and can get to the bottom of almost any soap dispenser-related problem. They also sell an excellent “Bradley approved” soap. Please see Bradley Instruction sheet 215-1286 for soap valve cleaning details and Champion Brand Products contact information.
Check Valve Troubleshooting
If water just dribbles or does not flow from sprayhead:
1. Turn off water supplies to fixture. 2 Inspect check valves for proper installation. See Stop, Strainer and Check Valve on page 19.
3. Open the stops and clean the strainers, if necessary.
If water sprayhead delivers all hot or cold water:
1. Turn off water supplies to fixture.
2. Inspect check valves for proper installation.
3. Open the stops and clean the strainers, if necessary.
4. Inspect mixing valve for proper installation (see Vernatherm Thermostatic Mixing valve on page 24)

Soap Valve - Liquid - S09-007S
This valve delivers a measured amount of soap with each upward stroke. The soap dis­penser has been standard on washfountains since 1983 and is not well-suited for very thick lotion soaps.
NOTE: Lotion soap will clog liquid soap valves. Use only lotion soap valves with lotion soap.
Soap Valve - Lotion - S09-057S
Soap Valve - Powdered - S09-010A
NOTE: Reducer plugs are available for use with fine granulated soap to reduce the flow.
NOTE: Valves can be changed from powdered to liquid by plugging the innermost, or “bearing” hole with rubber plug, part number 125-001AK. To change from liquid to powdered, the plug must be removed. If none is present, it will be necessary to drill out the bearing hole with a 1/2" or 5/8" drill. The plastic container configuration forms a natural template for locating the bearing hole.

Sprayhead Troubleshooting and Repair Parts
Problem: Water splashes over the rim of the bowl.
Cause: Foreign matter has reduced the size of the sprayhead slots, causing greater pressure at the
open slots.
Solution: Clean the sprayhead:
1. Disassemble the sprayhead and dislodge any dirt, lime build-up and foreign debris with a wire brush.
2. Sprayheads with rubber grommet spray rings may be cleaned by rubbing a coin over the grommet.
3. Throttle down the volume control (water spray should strike the bowl without splashing outside of the bowl).
Problem: Water flow diminishes from the sprayhead.
Cause: Strainer portion of the stop-strainer-check valve is plugged.
Solution: Remove and clean the strainer screen from the stop-strainer-check valve.
NOTE: The sprayhead shown below includes a perforated rubber spray ring grommet that is self­cleaning. The water pressure flexes the spray holes which slows accumulation of foreign matter and tends to “break loose” any such deposits that may have accumulated.

Adjusting the Vernatherm Thermostatic Mixing Valve
NOTE: This 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.
1. Check the temperature when approximately 1.0 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, follow the procedure below:
• Loosen temperature locking nut with wrench.
• Using a blade screwdriver, turn the adjustment stem counterclockwise to increase the temper-
ature or clockwise to decrease the temperature (Figure 10).
• Once desired temperature has been reached, tighten lock nut to prevent change in temperature.
2. Shut the hot water inlet off by closing the hot water stop-strainer-check valve. While the hot water supply is turned off, check to make sure the cold water flow is reduced. If the cold water is reduced properly, reopen the hot water supply.
3. Shut the cold water inlet off by closing the cold water stop-strainer-check valve. While the cold water supply is off, check to make sure that the hot water flow has shut down.

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.
Solution: 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 11 on Page 27).
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" per steps on Page 25.

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.
Drain Cleaning
Drains can be cleaned with a plumbers snake inserted through the drain spud after removing the strainer, or through the trap clean out plug
IMPORTANT: Do not put drain cleaners in bowl. Damage to bowl will result.
