Installation Sheet

PLUMBITE® PUSH ON THERMOSTATIC MIXING VALVES
Installation Instructions:
A. Assembly Procedure
Before installation, the hot (“H”) and cold (“C”) water inlet of the mixing valve must be cleared
and conrmed. The valve must be correctly connected to the respective supplies.
1. For a proper water tight t, use a deburring tool to remove burrs. Use a sand cloth to obtain
a smooth edge to pass by rubber seal of tting without damage. Tube must be round and free
of scratches and imperfections.
2. To ensure proper pipe installation depth:
• 1/2” Pipe, mark the pipe at 15/16” (24mm) from the end
• 3/4” Pipe, mark the pipe at 1-1/8” (27mm) from the end
3. While securely holding the valve, push the pipe/tubing straight in to valve. Press pipe/tubing until you
feel it rmly hit the stop inside the valve. It will be at the Installation Depth mark made above.
4. After installation check carefully for leaks.
5. To Remove: Snap removal tool over pipe/tubing. While rmly pressing removal tool against plastic
collar at valve opening, carefully slide pipe/tubing the opposite direction out of the valve.
Important: Failure to comply with all aspects of these instructions may result in unsafe performance.
All installations must comply with relevant state and local authority requirements.
Flush the system thoroughly before ttings the valve: It is CRITICAL that all debris is ushed from the pipework
prior to installing the valve. Not ushing the system properly is the most common cause of system diculties.
Check: Measure and note all site parameters (pressure, temperature, etc.) and check against the specications
of the chosen valve. If the site conditions are outside those specied for the valve then they must be rectied
prior to installing the valve.
Valve MUST NOT be subjected to heat during installations as this may damage the valve internals.
Valve MUST NOT be tted on steam-supplied systems.
Valve MUST NOT be frozen. If the valve is installed in situation where freezing is a possibility, then
suitable insulation must be tted to prevent damage to the valve. DO NOT use excess thread sealant
(in liquid, tape or other form) as this may cause the valve to fail.
Leave a copy of these instructions with the client for future reference.
Recommend to the client that the valve be checked annually to ensure its continued function.
B. Temperature Adjustment
1. Remove the protective cap on top of the valve.
2. Back-out the nut using a hexagon wrench:
To increase the temperature, turn counter-clockwise.
To decrease the temperature, turn clockwise.
3. Allow the mixed outlet temperature to stabilize for at least 60 seconds and once again
take a temperature reading. A thermometer is needed.
4. Repeat the procedure until the desired temperature has been reached at the outlet.
5. Lightly tighten the Adjustment Locknut to prevent further spindle movement.
6. Replace the top cover, by pushing the top cover rmly onto the top of the valve until it
clips back into place.
7. Check that the outlet temperature is stable over the full range of ow rates and that the
ow rate is adequate for the application.
8. Close the outlet xture, and then the mixing valve is now set and locked.
C. Check Valve Cleaning Procedure
1. Remove the push connector from TMV body
2. Flush the push end together with check valve and lter inside.
