PHYLRICH PHY1137 3-4 Medi Thermostatic Valve
GENERAL CHARACTERISTICS
WE RECOMMEND THAT ALL PLUMBING PRODUCTS BE INSTALLED BY A LICENSED PROFESSIONAL IMPORTANT: Thoroughly read instructions before installation.
WARNING: IF THIS VALVE IS INSTALLED UPSIDE-DOWN A REVERSE CARTRIDGE IS NOT AVAILABLE. CONSEQUENTLY, VALVE MUST BE REMOVED AND REINSTALLED RIGHT-SIDE UP.
- 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.
VALVE SPECIFICATION
- Recommended supply pressure = 20 to 80 psi (1,38-5,52 bar)
- Recommended hot water supply temperature = 120° to 140°F (48°-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.
- For use with shower heads rated at 1.8 gpm (6.8 L/min) or higher
- Female 3/4” NPT inlets and outlets
- Factory temperature setting = 100°F (38°C)
- Temperature range = 52° 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)
- Temperature stability = Compliant with ASSE 1016

ROUGH IN DIMENSIONS / ROUGH IN VALVE TO FRAME
(All dimesions shown are to the nearest 1/16”) Once the desired location has been determined, install a cross support beam to wall studs. Ensure to level the valve & secure to the cross support. The valve should be level horizontally, vertically, & parallel to finished wall.
- 3”x 8” Opening for finished wall for 2 valves 3” x 13” for 3 valves
Pre-assemble fittings before attaching to cross support. Attach the “COLD”
Inlet to Cold Supply & “HOT” Inlet to Hot Supply using copper supply lines.
IMPORTANT: Thoroughly flush supply lines to remove any debris prior to
installation to pevent damage & malfunction of thermostatic cartridge.
- Use plumber’s tape or thread sealant to all threaded port joints & attach to valve. All soldering/brazing of fittings shall be performed a minimum of 6” away from valve.
WARNING: DO NOT APPLY HEAT DIRECTLY TO THE VALVE AS THIS MAY DAMAGE RUBBER & PLASTIC SEALS & WILL AVOID WARRANTY. TURN ON WATER SUPPLIES TO VALVE & CHECK FOR LEAKS.
MAINTENANCE
THERMOSTATIC CARTRIDGE
Carefully remove the trim and plate and place in a safe location for the time
being. Use a flat head screwdriver to shut off the water supply to the
cartridge by turning the temporary shutoff screws clockwise until screw 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 11/16” socket wrench or adjustable wrench, if possible.
Gently pull the cartridge out of the housing body (rotating cartridge while
pulling may assist in removing). Clean the cartridge by rinsing it under
running water to remove any possible debris. Wipe cartridge and housing seat
clean and apply a thin film of NON-PETROLEUM GREASE to o-rings.
NOTE: Do NOT use oil based lubricants as this may cause the o-rings to
dry out over time and crack.
How to calibrate temperature:
To limit the amount of HOT water allowed to mix with cold water, use a 4 “
long flat blade screw driver to remove the stem. Unscrew and remove nut for
all thread using a 3/4” socket. Remove the limit safety stop and rotate the
stem counterclockwise till the desired maximum temperature is found. The
maximum temperature is factory set at 120°F. Once the desired temperature is
set, reinstall the safety stop at the maximum position. Proceed installing the
stem and trim.
Carefully install the cartridge back into the housing body and tighten nut to
10 ft-lbs (13,56 nm).
ATTENTION: Ensure the INDICATOR HOLE on cartridge is orientated at the 6
O’Clock position. The Temp erature stop must be in the 12 O’Clock position.
CHECK VALVES
Shut off water supply at main or upstream from valve body. Remove check
valve nut with a 15 mm socket wrench from the body. If check valve needs
replacement, forcefully remove check valve w/ needle nose pliers. Wipe check
valve and housing seat clean and apply a thin film of NON-PETROLEUM GREASE to
o-rings. Install new check valves by pressing them in evenly & ensuring check
valve snaps into place.
NOTE: Do NOT use oil based lubricants as this may cause o-rings to dry
out over time and crack.
Tighten check valves to 10 ft-lbs (13,56 nm).
Reinstate water supply from upstream and check for leaks.
Check operation of flow. If improved, proceed to reinstall extensions, trim, &
plate; otherwise, see PARTS BREAKOUT for any replacement parts needed.
