1) Install assembly with proper ow direction as marked on valve body. This is critical with CircuitSolver® Union
Assemblies that have an integrated check valve.
2a) Use suitable pipe thread sealant rated for domestic water applications on all male pipe threads; if using PTFE
sealant tape, make sure not to apply tape to the rst thread to avoid cutting the PTFE tape and causing potential
obstructions to ow.
2b) How to apply PTFE Tape:
1. Clean the male and female threads of any oil or dirt.
2. Apply tape to the male threaded end in a clockwise direction starting one thread back from the end.
Hold on to one end of the tape, and wrap the threads three to six times, keeping it tight.
3. Once the threads are completely wrapped, grab the tape with your thumb and index nger and snap it off.
NOTE: Upon tightening the assembly, verify that the shutoff valves are oriented so that their handles are accessible
and can be operated fully without obstruction. If a reorientation after nal installation is needed, loosen the
CircuitSolver® Union Nut to rotate the section so as to not disturb the tightened components and possibly cause a
leaky connection.
3) When using Uponor ProPEX® adapters, (CircuitSolver Models
ending in -PX) please consult the Uponor ProPEX® Installation
Manual for proper installation, tools, etc.

4) CircuitSolver® Union Assemblies are designed to be installed
at the end of each domestic hot supply just prior to the return line.
See diagram to the right.
5) For water systems with particulate/dirt problems, consider using
the CircuitSolver® Union Assembly with integrated strainer
(Model CSUAS) if one is not already used upstream.
*Strainer must be maintained in order to avoid ow obstruction.
6) A convenient drain port allows for the system branch to be
ushed without disconnecting plumbing lines.
