WARNING: TO ENSURE THE
ACCURATE AND RELIABLE
OPERATION OF THIS PRODUCT, IT IS
ESSENTIAL TO:
• Properly size each valve based on the indi-
vidual application.
• Properly design the recirculation system to
minimize pressure and temperature variations.
• Conduct an annual maintenance program to
ensure proper operation of all critical com-
ponents.
THIS VALVE MUST BE USED IN
CONJUNCTION WITH TEMPERATURE
ACTUATED POINT-OF-USE DEVICES THAT
COMPLY WITH ASSE 1016, 1069, OR 1070.
FAILURE TO COMPLY WITH PROPER
INSTALLATION INSTRUCTIONS COULD
CONTRIBUTE TO VALVE FAILURE, RESULTING
IN IN JURY OR DEATH.
