Model S59-2007 Series Installation and Maintenance Instructions

Pre-Installation Information

Overview

The Model S59-2007 Thermostatic Mixing Valve consists of a liquid-filled thermal motor and a piston control
mechanism with positive shut-off of hot water when cold water supply is lost. The valve body and cap are constructed
of bronze with replaceable corrosion-resistant components, including a stainless steel piston and liner. Integral stop/
checks are standard.

The maximum inlet temperature of the valve is 180°F (82°C), with a recommended inlet temperature of 120°F–140°F
(49°C–60°C). The valve has a maximum operating pressure of 125 PSI (860 kPA). Cabinet: The optional recess­mounted or surface-mounted cabinet is constructed of 18-gauge stainless steel with a 16-gauge stainless steel door.
The cabinet finish is either stainless steel or baked white enamel. The optional cabinet window is made of Plexiglass.

Supplies recommended for installation

• lockable shut-off on the outlet if tempered water is supplied to a remote location

• lockable shut-off on the inlets/supplies

• unions on all connections to facilitate removal of valve

• (6) 3/8" wall anchors and fasteners for surface-mounted cabinet

• (4) 1/4" fasteners (and wall anchors, if necessary) for recess-mounted cabinet

Tools required for temperature adjustment

• 5/32" Allen wrench

Tools required for maintenance/troubleshooting

• 3/4" wrench (for acorn nut removal)

• 15/16" socket wrench and needle-nose pliers (for piston liner removal)

• 1/2" deep well socket wrench (for piston assembly’s upper seat removal)

Installation Instructions

CAUTION: If optional cabinet is to be used, the cabinet must be mounted before the valve is

installed. Please refer to the cabinet mounting instructions on pages 4-5.

NOTE: Flush the supply lines before beginning installation.

NOTE: When the stop/check valves are in the closed

position, the stem for the stop/check will be 1/4" above

the stem nut. When the stop/check valves are in the open

position, the stem will extend out approximately 1/2" (13 mm)
from the stem nut.

1. Connect the hot and cold valve supply inlets to the
appropriate hot and cold supply piping.

2. Connect the mixed valve supply outlet from the valve to
the tempered supply piping.

3. Pressurize the thermostatic mixing valve and check for
pipe leaks.

4. Slowly open the outlet valve to fill the piping system.

5. Check the temperature when approximately 2½–4 GPM
water flow is reached (equivalent to one shower) and
adjust if necessary (the range of the valve is 95°F–115°F
(35°C–46°C). To adjust the temperature, follow the
procedure below:

• remove the acorn nut to expose the set screw

• using a 5/32” hex-head Allen key, turn the set screw counterclockwise to increase the temperature or

clockwise to decrease the temperature.

NOTE: The standard preset factory temperature setting is 105°F (41°C). Consult proper medical and/or safety

authorities for the optimum temperature recommended for your particular application.

6. Shut the hot water inlet off by closing either the hot water check valve or inlet valve. While the hot water supply
is turned off, check to make sure the cold water is reduced to .5 GPM or less. If the cold water is reduced
properly, reopen the hot water supply.

7. Shut the cold water inlet off by closing either the cold water check valve or inlet valve. While the cold water
supply is off, check to make sure that the hot water flow has shut down.

Note: Flush the supply lines before beginning installation.

1. Rough in a 11½" W x 13" H hole in the wall for the cabinet.

2. Measure and mark the cabinet mounting hole locations at the dimensions shown. Install four ¼" wall anchors, if
required (supplied by installer).

3. Insert the cabinet into the wall opening and secure into place with four ¼" wall fasteners (supplied by installer).

4. Insert the valve into the bracket in the cabinet (right side of the valve goes in first). Install the valve, elbows and
stops onto the inlet and outlet piping.

5. Continue with the valve installation procedure found on page 3.

Model S59-2007 Series Installation and Maintenance Instructions

Thermostatic Mixing Valve Maintenance

For maximum efficiency, your thermostatic mixing valve requires a minimum amount of maintenance. Follow the
procedures outlined below to achieve highest performance.

Check the piston for smooth movement

1. Remove the valve's top cap and thermostat.

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 and liner assembly needs to be cleaned.
Follow the method outlined below for cleaning the
piston/liner:

• remove the cap and thermostat

• using a 15/16" socket wrench, loosen the piston/liner

assembly from the valve body and lift the assembly
out with a needle-nose pliers

• disassemble the piston/liner assembly components

as shown (use a 1/2" deep-well socket to remove the
upper seat).

• 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 liner).

• reassemble the piston/liner assembly components

and retest the piston.

3. If, after a thorough cleaning, the piston does not move
freely, the piston/liner assembly must be replaced.
Contact your Bradley representative and ask for Piston/
Liner Kit (part number S65-205).

Check the thermostat for proper operation

1. At room temperature (80° or less), remove the top cap
and thermostat.

2. Place the thermostat into a small container filled
with 115° water. The pushrod should pop out of the
thermostat approximately 1/10".

Top Cap

3. If the thermostat pushrod does not pop out, the
thermostat must be replaced (it cannot be repaired).
Contact your Bradley representative and ask for
Thermostat Kit (part number S65-417).

Adjust the temperature

1. Turn on the water and let it run until at least 3 GPM is
flowing through the valve.

2. Remove the acorn nut to expose the set screw.

3. Using a 5/32" hex-head Allen key, turn the set screw
counterclockwise to increase the temperature or
clockwise to decrease the temperature.

4. When the adjustment is complete, replace the cover
screw and turn off the water.

Thermostatic Mixing Valve Troubleshooting

NOTE: Before attempting to troubleshoot the valve or disassemble the components, check for the following conditions:

• make sure the stop/check valves are fully open (the slotted stem must extend out approximately 1/4" from

the valve cap) (see Figure 1 on page 3) and that all inlet and outlet shut-off valves are 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 15° 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 Cause Solution

No hot water flow

move freely.

See "Check the thermostat for proper operation" above
and follow the step-by-step procedure.

Dirt and debris have collected on the stop/check valve
seat, limiting movement.Remove the stop/checks, clean
the seat and reassemble the valve. The stop/checks may
also be disassembled and cleaned. The components may
be brushed with a small wire brush to remove debris. If
the stop/check valves need to be replaced,contact your
Bradley representative and ask for Stop/Check Valve (part
number S27-102 — Rough Brass, S27-292A — Chrome).

The inlet supply line to the mixing valve is being
shared by other pieces of equipment that are
used only periodically, such as laundry appliances
or washdown stations. It may reduce the inlet
pressure to the mixing valve to less than 3 PSI.
The supply line size may not be large enough to
supply both the valve and the other appliances.

components with a

representative and ask for O-Ring/Seal Kit (part number
