INSTALLATION INSTRUCTIONS FOR
1/2 Mini Thermostatic Valve 1-115
w/ VOLUME CONTROL 1-116
w/ (TWO) 1/2” VOLUME CONTROL 1-138
w/ 3 Way Diverter 1-117
w/ 2 Way Diverter 1-132
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, THE VALVE MUST BE REMOVED AND REINSTALLED RIGHT-SIDE UP.
- The valve is designed with two outlets for ease of installation but is not intended to be used simultaneously 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 the correct temperature setting
to prevent any risk of scalding prior to consumer use.
For use with shower heads rated at 1.3 GPM (4.9 L/min) or higher

(All dimensions 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 the finished wall.
-
Opening for Finished wall
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 prevent damage & malfunction of the 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 4” 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 them 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 the screw stops. Ensure to close both the hot and cold sides of the water supplies. Remove extensions & cover sleeves to gain access to the cartridge nut. Unscrew the cartridge nut using a 1 1/32” plumbers wrench or adjustable wrench, if possible.
Gently pull the cartridge out of the housing body (rotating the cartridge while pulling may assist in removing it). 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 screwdriver to remove the stem. Unscrew and remove the cover
sleeve using a 3/4” socket. Remove o-ring and pull off limit 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 limit and stop at the maximum position (Against
Pin). Proceed to install the stem and trim.
CHECK VALVES
Shut off the water supply at the main or upstream from the valve body. Remove
check valve nut with a 5/8” (16mm) socket wrench from the body.
If the check valve needs replacement, forcefully remove the 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 the 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 valve nut(s) to 10 ft-lbs (13,56 nm).
Turn on the 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.
