1) Install assembly with proper ow direction as marked on valve body. This is critical with 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) When using Viega ProPress® adapters, please consult the Viega ProPress® Installation Manual for proper
installation, tools, Smart Connect technology, etc.

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