1) We recommend that you use a shut off valve before and after the
CircuitSolver® Thermal Disinfection Dual Valve
and a union after the valve. See schematic diagram on reverse side.
2) Install valve with proper flow direction as marked on valve body. This is critical with valves that have an integrated
check valve.
3a) Use suitable pipe thread sealant rated for domestic water applications on all male pipe threads except on the
stainless steel
CircuitSolver®
Thermal Disinfection Dual Valve
union threads (this connection has an integrated
o-ring that fully seals when hand tightened); if using PTFE sealant tape, make sure not to apply tape to the first
thread to avoid cutting the PTFE tape and causing potential obstructions to flow.
3b)
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 finger 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 final 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.
4) When using Uponor ProPEX® adapters, (CircuitSolver Models
ending in -PX) please consult the Uponor ProPEX® Installation Manual
for proper installation, tools, etc.

CircuitSolver®
valves are designed to be installed at the end
of each domestic hot water supply just prior to the return line.
See diagram to the right.
6) For water systems with particulate/dirt problems,
consider using a strainer if one is not already used upstream.
*Strainer must be maintained in order to avoid flow obstruction.
