Before You Begin
NOTICE: Do not install the valve under a whirlpool surround or any location where the temperature may
reach temperatures over 104°F (40°C). The valve and its integrated power supply is rated to operate in
temperatures up to 104°F (40°C).
NOTICE: Do not apply excessive heat near the valve or apply flux or acids directly onto the valve. This
valve contains plastic and rubber components which will melt if heat is directly applied.
NOTICE: Do not apply petroleum-based lubricants to the valve components. Doing so will damage the
valve components.
NOTICE: Do not use oil-based, non-setting compounds, such as plumbers putty, on the threaded
connections.
NOTICE: If the digital valve will be used for a bath/shower application, the bath fill supply line must be
routed from the #1 outlet port.
Observe all local plumbing, building, and electrical codes.
Read these instructions and determine all required components along with their installation
locations before beginning this installation.
Provide access for servicing.
For optimum performance, 1/2" dedicated water supply lines are recommended.
When possible, install the valve prior to installing the interface(s).
