Introduction
The BRIZO MultiChoice Valve Trim system includes two key models—the T604 thermostatic valve trim and the T60P pressure balance valve trim—designed for precision temperature control in tub and shower applications. These valves are engineered to require manual adjustments to ensure safety and comfort, particularly when external water conditions such as heater settings or line pressure change. The documentation provided by the manufacturer outlines critical installation, maintenance, and user safety protocols that must be followed by both installers and end users.
Installation and maintenance procedures are detailed in the official instruction manuals for the T604 and T60P models. These manuals emphasize the importance of proper installation, label placement, and periodic inspection to prevent issues such as hot water burns or system failure. This article synthesizes the instructions and warnings provided in the official documentation to offer a comprehensive overview for installers and users.
Key Safety and Installation Considerations
The T604 and T60P models both require manual adjustments due to the absence of automatic temperature compensation for changes in hot water heater settings or inlet conditions. This design means that the temperature knob must be adjusted manually by the installer and potentially readjusted later if the water heater settings or seasonal conditions change.
The documentation repeatedly stresses that failure to adjust the temperature knob after installation or after a change in water heater settings can lead to uncomfortable or dangerous water temperature fluctuations. Such fluctuations may result in burns from hot water or discomfort from sudden drops in temperature caused by pressure changes, such as when a dishwasher or washing machine is in use.
To mitigate these risks, the installer is responsible for ensuring the following: - The temperature knob is set to a safe and comfortable discharge temperature. - The rotational limit stop is adjusted properly to restrict the range of motion of the valve handle. - The appropriate labels are affixed in visible locations—inside a cabinet door or on the water heater—to inform the user of the need for potential future adjustments.
Additionally, the installer must document their name, company, and the date of adjustment on the caution label, which is then attached to the back of the nearest cabinet door and the warning label is placed on the water heater. This ensures accountability and provides a reference for future inspections or adjustments.
Installation Process and Precautions
Before installation, it is essential for the installer to read all instructions carefully. The documentation warns that failure to do so may result in personal injury, property damage, or product failure. The manufacturer explicitly disclaims responsibility for any product failure caused by improper installation, underscoring the critical role of the installer in the process.
The installation process includes the following key steps: - Ensuring the water supply is turned off. - Installing the valve according to the manufacturer's specifications. - Adjusting the temperature knob and rotational limit stop as necessary. - Attaching the required labels in the specified locations.
For both the T604 and T60P models, the rotational limit stop must be set by the installer to ensure that the valve handle does not rotate beyond a safe temperature range. This adjustment is particularly important for the T60P model, which includes a rotational limit stop that must be set during installation and potentially readjusted due to seasonal changes in water temperature.
Maintenance and Cleaning Procedures
Periodic maintenance is necessary to ensure the continued safe and efficient operation of the BRIZO MultiChoice Valve. The documentation provides specific guidelines for cleaning and inspecting the valve cartridges, particularly in areas with water that contains lime, rust, or other contaminants.
For the T604 model, low water flow may be caused by clogged screens within the thermostatic cartridge. The cleaning process involves the following steps: 1. Turn off the water supply. 2. Remove the handle assembly. 3. Unscrew the hex-shaped portion of the cartridge from the brass section. It is important to hold the brass section securely to prevent damage to the cartridge. 4. Clean any debris from the screens under running water. If the debris is difficult to remove, soak the screens overnight in a 50% water and 50% vinegar solution. 5. Reassemble the cartridge and replace the handle. 6. Turn the water supply back on. 7. Reset the rotational limit stop before using the valve.
For the T60P model, the maintenance process includes inspecting the pressure balance valve for contaminants. The documentation recommends removing the valve cartridge and following similar steps as outlined for the T604 model. After cleaning, the valve should be shaken vigorously to check for a rattling sound, which indicates that the unit is functional and can be reinstalled. If no rattling is heard, the valve cartridge must be replaced.
In both cases, care should be taken to avoid using harsh abrasives or polish when cleaning the exterior of the valve. The finish is designed to be durable, but improper cleaning methods can cause damage. Instead, the documentation recommends simply wiping the surface with a damp cloth and blotting dry with a soft towel.
Labeling and Documentation Requirements
Label placement is a critical aspect of the installation process for both the T604 and T60P models. The documentation specifies that the installer must place two types of labels: 1. A caution label with the installer's name, company, and the date of adjustment on the back of the nearest cabinet door. 2. A warning label on the water heater to inform the user of the need for potential temperature adjustments.
These labels serve as permanent records and reminders for both the installer and the user. They also ensure compliance with safety standards and provide a reference for future maintenance or troubleshooting.
In addition to label placement, the installer is required to leave the instruction manual for the user's reference. This manual contains detailed information on installation, adjustment, and maintenance procedures, as well as contact information for customer support.
Compliance and Standards
The BRIZO MultiChoice Valve Trim systems are certified to meet or exceed the following industry standards: - ASME A112.18.1/CSA B125.1 - ASSE 1016
These standards ensure that the valves are manufactured and tested to provide safe and reliable performance under a variety of conditions. Compliance with these standards is verified through rigorous testing and inspection processes.
The documentation also emphasizes that the valves are designed to be set by the installer to ensure a safe maximum temperature. Any changes to the settings may increase the discharge temperature beyond safe limits, potentially leading to hot water burns. Therefore, the installer must be knowledgeable about the proper adjustment procedures and must inform the user of any potential future adjustments that may be necessary.
Troubleshooting Common Issues
Several common issues can arise with the BRIZO MultiChoice Valve, particularly related to water flow and temperature control. The documentation provides guidance for troubleshooting these issues and ensuring that the valve operates correctly.
For example, low water flow is a common issue that may be caused by clogged screens within the thermostatic cartridge of the T604 model. In such cases, the recommended solution is to clean the screens as described in the maintenance section.
For the T60P model, periodic inspection of the pressure balance valve is recommended if the water in the area contains lime, rust, or other contaminants. The documentation provides step-by-step instructions for inspecting and cleaning the valve cartridge, as well as a method for testing its functionality by shaking it to listen for a rattling sound.
If the valve continues to experience issues after cleaning and inspection, it may need to be replaced. The documentation includes information on replacement parts and provides a link to the BRIZO website for further assistance.
