PHYLRICH DFPHY Pressure Balance Valve Installation Guide

PHYLRICH DFPHY Pressure Balance Valve

Product Information

1/2 Pressure Balance Valve

The 1/2 Pressure Balance Valve, with part numbers DFPHY and DFPHYID, is a plumbing product designed for use in showers and tubs. It is important to have a licensed professional handle the installation of this valve. The valve is engraved with an H and C on top, indicating the hot and cold water outlets. It features two outlets for easy installation, but they should not be used concurrently as it will reduce the valve’s performance. The unused outlet should be plugged with a 1/2 NPT plug (not provided).

The valve includes a check valve, a 16 point stem, a diverted body, an M4 stem screw, an O-ring, a 9/16-20 threadall, an extension mounting nut, and a diverter cartridge.

Operating pressures between the hot and cold supplies should not vary more than 30 psi. If the water pressure exceeds 70 psi, it is recommended to install a pressure reducing valve. The installer should ensure that the mixing valve complies with local plumbing
codes when setting the temperature on the water heater. It is also the installer’s responsibility to verify the correct temperature setting to prevent scalding risks.

Rough Valve Installation

1. Once the desired location has been determined, install a cross support beam to the wall studs.
2. Level the valve horizontally, vertically, and parallel to the finished wall. Secure it to the cross support.
3. The placement of the valve and cross support within the wall should be determined by the MIN/MAX limits. Refer to the ROUGH-IN DIMENSIONS for detailed valve dimensions.

Water Connections

1. Pre-assemble fittings before attaching them to the valve.
2. Attach the COLD INLET to the COLD SUPPLY and the HOT INLET to the HOT SUPPLY using copper supply lines and 1/2 NPT male adapters.
3. Use plumber’s tape in the areas shown in the figure to ensure proper sealing.
4. Thoroughly flush supply lines before installation to remove any debris that may cause damage or malfunction of the pressure balance cartridge.
5. Use plumber’s tape or thread sealant on all threaded port joints and attach them to the valve.
6. Ensure that any soldering or brazing of fittings is at least 6 inches away from the valve.

Caution: Do not overtighten or apply excessive force.

Warning: Do not apply heat directly to the valve as it may damage rubber and plastic seals, resulting in voiding the warranty.

Turn on the water supplies to the valve and check for leaks.

GENERAL CHARACTERISTICS

WE RECOMMEND THAT ALL PLUMBING PRODUCTS BE INSTALLED BY A LICENCED PROFESSIONAL

IMPORTANT : Thoroughly read instructions before installation Please note that the valve is engraved with an “H” and “C” on top of the valve. The valve is designed with two outlets for ease of installation, but are not intended to be used concurrently with each other. Using both outlets will reduce the performance of the valve. Determine which outlet port will be used for the installation and plug the other outlet with a 1/2” NPT plug (not provided).

VALVE SPECIFICATIONS

• Female 1/2” NPT inlets and outlets
• Factory temperature setting = Max. 118°F (48°C)
• Temperature range = 52°F to 118°F (11°-48°C)
• Temperature hot supply = 149° to 180°F (65°-82°C)
• Temperature cold supply = 50° to 72°F (10°-22°C)
• Adjustable Temperature limit stop

• Recommended supply pressure = 20 to 80 psi (1,38-5,52 bar)
• Recommended hot water supply temperature = 120°F to 140°F (48°C-60°C)
• Operating pressures between hot and cold supplies should vary no more than 30 psi (2,07 bar).
• If water pressure exceeds 70 psi (4,83 bar), install a pressure reducing valve.
• Ensure the mixing valve is in compliance with local plumbing codes when setting the temperature on the water heater.
• It is the installer’s responsibility to verify correct temperature setting to prevent any risk of scalding prior to consumer use.

ROUGH VALVE TO FRAME

Once the desired location has been determined, install a cross-support beam to wall studs.
Make sure to level the valve and secure to the cross support. The valve should be level horizontally, vertically and parallel to finished wall.
Placement of valve and cross support within the wall shall be determined by the MIN/MAX limits. For complete detailed valve dimensions see ROUGH-IN DIMENSIONS.

WATER CONNECTIONS

• Pre-assemble fittings before attaching to valve. Attach the “COLD” INLET to the COLD SUPPLY and “HOT” INLET to the HOT SUPPLY using copper supply lines and 1/2” NPT male adapters. Use plumbers tape in areas shown on above figure.
• IMPORTANT: Thoroughly flush supply lines to remove any debris prior to installation, preventing possible damage and malfunction of pressure balance cartridge.
• ATTENTION: Use plumbers tape or thread sealant to all threaded port joints and attach to valve. All soldering/brazing of fittings a minimum of 6” away from valve.
• WARNING: DO NOT APPLY HEAT DIRECTLY TO THE VALVE AS THIS MAY DAMAGE RUBBER & PLASTIC SEALS AND WILL RESULT IN VOIDING THE WARRANTY.
• Turn on water supplies to valve and check for leaks.

TEMPERATURE SETTINGS

• WARNING: The valve is set by the factory to deliver water at the highest temerature possible. It is the installer’s responsibility to properly set the desired and/or required maximum temperature setting to prevent risk of scaldingor any other severe injury prior to consumer use. The installer is responsible in setting the correct high temerature limit based on user preferences and all local plumbing code requirements.
• Remove temerature limit stop from the top of cartridge.
• Rotate stem counter-clockwise to start water flow. Temperature will increase when stem is rotated further.
• Use a temperature measuring device (thermometer) at the outlet flow to determine desired maximum temperature.

IMPORTANT: To prevent any severe injury we recommend that the maximum temperature setting should be no greater than 115°F (46,1°C).
Place temperature limit stop back onto cartridgein the desired arrangement.
Rotating the temperature limit stop further clockwise will limitthe rotation of the cartridge which in turn limits the maximum temperature.

MAINTENANCE

PRESSURE BALANCE CARTRIDGE

• Carefully remove the trim and plate and place in a safe location for the time being.
• Use a flat head screwdriverto shut off the water supply to the cartridge by turning the temporary shutoff screws clockwise until srcrew stops. Ensure to close both the hot and cold sides of the water supplies.
• Remove extensions to gain access to the cartridge nut. Unscrew the cartridge nut using a plumbers wrench or adjustable wrench, if possible.
• Gently pull the cartridge out of the housing body (wiggling cartridge while pulling may assist in removing).
• Clean the cartridge by rinsing it under running water to remove any possible debris. Keep the orientation of the cartridge in mind when reassembling.
• Wipe cartridge and housing seat clean and apply a thin film of NON-PETROLIUM GREASE to the o-rings.
• NOTE: DO NOT USE OIL BASED LUBRICANTS AS THEY MAY CAUSE THE O-RINGS TO DRY OUT OVER TIME AND CRACK
