General Characteristics
In case of instantaneous heaters, hot water flow has to at least meet flow required by heater and maintain burning. (Specified by heater
manufacturer)
Operating Specifications
Hot water supply temperature:
Maximum: Reference manufacturing specification
Minimum: 140°F
Minimum difference between hot and mixed temperature is: 50°F
Operating Pressure:
Maximum: 70 PSI
Minimum: 20 PSI
Operating pressure (on hot and cold line) should be kept as balanced as possible in order to assure maximum efficiency.
When the pressure is greater than 70 PSI, a pressure reducer is required and must be fitted before valve.
Technical Data
The temperature control knob is graduated from 75°F to 120°F with auto stop at 100° to avoid scalding.
Temperature limit setting of less than 120°F.
Fit a stop valve/volume control between thermo valve outlet and end device(s).
Plumbing Recommendations
• An independent water supply for both hot and cold is required. Do not pipe off ring main.
• Large runs of pipe work will cause frictional loss of pressure.
• The recommended main water supply piping to valve shall be 3/4” minimum.
• If more than one valve is installed, the recommended main water supply piping to valve shall be 1” minimum, reducing to 3/4” within
24” of each valve.
(Ensure adequate supply from both hot and cold water can be maintained.)
Water By-Laws
The mixing valve should be installed in compliance with the water by-laws. For further details refer to the latest copy of by-laws guide
or your local water authority.
Rough in Valve Installation
Note: Use Teflon tape or equivalent to seal all threaded port joints.
Do not remove mud cover from valve before locating mounting surface depth in the wall.
Do not turn the cartridge stem - temperature settings are pre-calibrated at the factory.
Install plug into one of the two outlet ports. Note: For proper valve operation only one outlet port may be used.
Mount valve to cross support using shims and screws (not included). Valve shall be perpendicular and fixed
firmly to cross support to achieve proper trim attachment.
Place the cross support with valve between wall studs. The min./max. valve exposure template on the mud
cover and vertical height desired within tub/shower enclosure determines the exact cross support placement.
Attach cross support to wall studs.

Connecting Water Supply
Thoroughly flush supply lines to remove any debris, metallic shavings, flux, etc.
Shut off water supply to valve.
Hot and cold water supplies MUST be connected to designated sides for proper operation of valve.
If solder/brazing the fitting connections, pre-assembly hot & cold adapter fittings to copper piping. Using
Teflon tape or equivalent to attach adapter to appropriate inlet port.
Important: All excessive heat shall be a minimum of 4” from valve.
Connect outlet pipe to stop valve/volume control (not included), and from stop valve pipe to various end
device(s).
Turn on water supply to valve and check for leaks.

Installing Trim & Temperature Setting
Remove and discard mud cover and screws.
Slide sleeve over valve body with grooved notch to topside.
Slide cover plate with gasket over sleeve and attach with decorative screws provided (see Figure 4).
Orient and position limit stop as shown in Figure 5. Slide Nomenclature ring over sleeve, aligning 100° to
notch in sleeve.
Open shut-off valve and verify water temperature at outlet device by using a thermometer. NOTE: The safe
and factory set temperature is 100°F. The next step refers to adjustment of the temperature, otherwise skip
to the following step.
Rotate cartridge stem to adjust temperature:
(clockwise = colder or counterclockwise = hotter)
Place bonnet onto cartridge stem with red button (100°F) positioned straight up and inline with notch on the
sleeve (see Figure 6).
Place decorative handle onto bonnet and secure with setscrew.

Maintenance and Troubleshooting
The thermostatic valve has various screens that filter debris and unwanted particles that may damage the
valves' cartridge and operation. Through years of use, these screens may build up with impurities and
limescale, restricting the flow of water through the cartridge and or check valves. The following steps
describe removal and cleaning procedure.
Cartridge (Reference Figure 7)
Carefully remove the handle, bonnet, stop ring, cover plate and sleeve.
Shut off the water to cartridge by tightening center screw on each check valve, 7 turns maximum.
Unscrew the cartridge using 1-3/16” or adjustable wrench; gently remove cartridge from housing.
Clean the screens by rinsing the cartridge under running water. If necessary, soak in a 50/50 mix of white
vinegar and water to remove limescale.
Wipe cartridge and housing with wet cloth and apply a thin film of non-petroleum grease to o-rings. Do not use
Vaseline.
Carefully install cartridge into housing and tighten to 10 ft-lbs.
Fully open check valves and inspect for leaks.
Check operation and flow. If improved, proceed to step 9, otherwise see checkvalve section below.
Reinstall trim and set temperature per section 3.

Care and Cleaning
The lustrous finish on your Restoration Hardware Bathware fixture should
be treated with care. Improper handling or cleaning can damage the surface
of any metal finish. Use a soft cloth to wipe clean. Avoid harsh abrasive
cleaners. Water contains lime and other mineral deposits that will be left on
the surface after the water has evaporated. You can prevent these deposits
from forming by always wiping the fixture dry immediately after use.
