PowerStation
™
is a complete, fully assembled water tempering system,
designed to provide safe water throughout commercial and institutional
facilities. PowerStation
™
features the HydroGuard
®
XP MM430 or LFMM430
and SH1430 or LFSH1430 master tempering series valves which utilize
paraffin-based actuation technology to sense and adjust outlet temperature.
Each PowerStation
™
is mounted on heavy-duty, welded struts and factory
tested as a complete system. Each PowerStation
™
includes an engineer
specified circulator, GFCI outlet, combination temperature/pressure gauges
and Powers' triple-duty checkstops. Optional equipment includes an
Aquastat.
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.
