Important Notices & Warnings

CAUTION: To reduce the risk of injury due to hot water burns, ensure enclosed labels are applied as specified.

NOTICE TO INSTALLER: Place the provided warning label on the water heater next to the temperature adjustment knob, or near the valve where the owner will see it (e.g., inside a cabinet door).

WARNING: This series of tub/shower valves does not automatically adjust for changes in hot water heater or inlet temperature. Manual adjustment of the valve setting is required if the water heater or inlet temperature changes. Failure to re-adjust may result in hot water burns or extreme cold. Verify temperature knob settings after installation to prevent uncomfortable water temperature changes. Consult the installation instruction sheet or call 1-877-345-BRIZO for assistance.

CAUTION: This system/device must be set by the installer to ensure safe, maximum temperature. Any change in setting may raise discharge temperature above safe limits, potentially causing hot water burns.

NOTICE TO INSTALLER: As the installer, you are responsible for properly installing and adjusting this valve per the instructions. Inform the owner/user of the need for manual temperature adjustments due to seasonal changes or other factors. If unsure, refer to page 5 or call 1-877-345-BRIZO (2749).

After installation and adjustment, affix your name, company name, and date to the caution label and attach it to the cabinet door. Leave this instruction sheet for the owner's reference.

WARNING: This thermostatic valve minimizes effects of outlet water temperature changes but may not protect from burns if other temperature controlling devices fail, the knob is not properly set, or hot water temperature changes after settings are made. Do not install shut-off devices on any outlet of this valve, as this can prevent the valve from balancing hot and cold water pressures.

Installation Guide

1. Cartridge Installation

Preparation: Turn off water supplies. Remove cover (1), bonnet nuts (2), and test caps (3) from the rough-in body (4) R75000. Place a bucket or container under the valve body. Slowly open water supplies to flush debris, then turn supplies off again.

Diagram Description: Diagram A shows the rough-in body components: (1) Cover, (2) Bonnet nuts, (3) Test caps, (4) Rough-in body (R75000). Diagram B illustrates inserting the valve cartridge (1) into the rough-in body (4). It shows the cartridge with o-rings (3) and indicates the correct orientation: 'UP' (2) at the top, 'H' for the hot side, and 'C' for the cold side. A light coating of plumber's grease on o-rings may aid assembly.

Normal Installation: Ensure the cartridge is oriented correctly as per Diagram B.

Back-to-Back or Reverse Installation: For installations where hot is on the right and cold is on the left, rotate the valve cartridge (1) so 'H' is on the hot side, 'C' is on the cold side, and 'UP' (2) appears on the bottom. Apply silicone lube to the three o-rings for easier installation. Ensure cartridge keys engage fully with the rough-in body slots.

Diagram Description: Diagram C shows the orientation for back-to-back or reverse installation.

Securing the Cartridge: Thread bonnet nut (2) onto the cartridge and hand-tighten securely. Slide o-ring (1) over the cartridge and bonnet.

2. Diverter Cartridge Installation

Preparation: Apply silicone lube to the o-ring (2) to ease diverter sleeve (3) installation. Rotate diverter cartridge (1) so the pin is at the bottom for correct installation. Apply silicone lube to o-rings (4) to ease diverter sleeve (3) installation. Align diverter sleeve notches with rough-in body (5) notches.

Diagram Description: Diagram A shows the diverter cartridge (1), diverter sleeve (3) with o-rings (4), and rough-in body (5). Diagram B shows the slip-on installation of bonnet nut (6) over the diverter sleeve (3).

Installation: Slide bonnet nut (6) over diverter sleeve (3) and thread into the rough-in body. Hand-tighten securely.

3. Trim Installation

Trim Sleeve Installation: Slide trim sleeve (1) over the cartridge, bonnet (2), and o-ring. Ensure the sleeve is positioned correctly with the set screw access hole downward. The o-ring helps secure the trim sleeve.

Escutcheon Installation: Secure the backplate (3) to the rough-in body (4) using four screws (5). Ensure the backplate is oriented front-side forward with markings visible. For uneven surfaces, use sealant around the backplate. Align escutcheon (6) holes with cartridges and slide onto the backplate. Slide sleeve (7) onto the escutcheon and secure by threading trim nut (8) onto the diverter sleeve. Do not overtighten. Slide diverter base (9) over the trim nut. An optional extension kit (RP100669) is available for walls up to 1" thick.

Diagram Description: Diagram B shows escutcheon installation components: backplate (3), rough-in body (4), screws (5), escutcheon (6), sleeve (7), trim nut (8), and diverter base (9).

Volume Handle Installation: Slide volume control handle (10) over the cartridge, aligning flat surfaces. The handle lever should point downward (6 o'clock) in the off position. Secure the handle with set screw (11). Start the set screw in the handle before installing onto the cartridge, then tighten using an Allen wrench through the access hole in the trim sleeve.

Diagram Description: Diagram C shows volume handle (10) and set screw (11).

4. Diverter Handle Installation

Slide diverter handle (1) onto diverter sleeve (2). Using an Allen wrench, insert set screw (3) into the handle. Apply pressure and insert set screw cover (4) until properly seated.

Diagram Description: Diagram E shows diverter handle (1) being attached to diverter sleeve (2) with set screw (3) and cover (4).

5. Installation and Adjustment of the Temperature Handle

WARNING: Failure to properly adjust the temperature handle may cause injury. Complete these steps carefully.

Adjust Temperature Limit Stop: Turn on water supplies. Let water run at full hot. Place a thermometer in a plastic tumbler and hold it in the water stream. Aligning the splines, place the temperature handle (1) onto the cartridge stem (2). Rotate the handle until the desired maximum temperature is achieved (not more than 120°F or as mandated by local plumbing code).

After setting the desired temperature, remove the temperature handle (1). Replace the handle onto the cartridge stem, ensuring the handle limit stop (4) aligns with the volume handle limit stop (3). Secure the temperature handle (1) to the valve stem with screw (5). Ensure o-ring (6) is assembled on handle cap (7). Install the handle cap by pressing it onto the temperature handle (1) and secure it by tightening screw (8) from the underside of the handle.

Diagram Description: Diagram D illustrates the temperature handle adjustment process: placing handle (1) on stem (2), aligning limit stops (3, 4), securing with screw (5), and attaching handle cap (7) with screw (8).

Potential Injury Warning: Scald or thermal shock injury could result from cross-flow if the shower outlet is blocked or restricted (e.g., pause control on showerhead). Point the showerhead away from you when restarting flow, or install inlet check valves on both supply lines to prevent injury.

Maintenance & Troubleshooting

Troubleshooting Common Issues

Cannot Receive More Than a Trickle of Water: Ensure both hot and cold supply lines are pressurized. If only one side is pressurized, the system will not allow adequate flow.
Faucet Leaks from Showerhead: Remove the showerhead. Turn water on and off to check if the cartridge is leaking or the showerhead is draining slowly. Clean the showerhead if water drains slowly. If leaks persist, shut off water supplies and replace the cartridge assembly (RP47201).
Unable to Set or Maintain Mixed Water Temperature: Shut off water supplies. Remove the handle assembly, trim sleeve, and bonnet nut. Verify that the 'H' marking on the cartridge aligns with the hot inlet and the 'C' marking aligns with the cold inlet. The thermostatic cartridge will not function correctly if hot and cold inlets are reversed.
Low Flow: Low flow may be caused by clogged screens within the thermostatic cartridge. To clean the screens:
1. Shut off water supplies.
2. Remove the handle assembly.
3. Unscrew the hex-shaped portion of the cartridge from the brass section. Hold the brass section securely while rotating the hex counter-clockwise. Failure to secure the brass section may damage the cartridge.
4. Carefully clean debris from the screens under running water. If difficult, soak screens overnight in a 50% water and 50% vinegar solution.
5. Reassemble the cartridge.
6. Replace the handle.
7. Turn water back on.
8. Reset the limit stop before using the valve.
