Powers ES150 Emergency Tempering Valves with Internal Cold Water Bypass - Manual

ES150 HydroGuard ® XP Emergency Tempering valves thermostatically blend
hot and cold water to deliver tepid water to emergency fixtures, quickly com-
pensating for temperature variations due to the changes in inlet temperature
or pressure. Powers' exclusive internal bypass ensures cold water flow in
the event of loss of hot water.

WARNING !
FAILURE TO COMPLY WITH PROPER
INSTALLATION AND MAINTENANCE
INSTRUCTIONS COULD CONTRIBUTE TO THE
VALVE FAILURE, RESULTING IN INJURY AND DEATH.
TO ENSURE THE ACCURATE AND RELIABLE
OPERATION OF THIS PRODUCT, IT IS ESSENTIAL TO:
• Properly size each valve based on the individual
application.
• Properly design the recirculation system to minimize
pressure and temperature variations.
• Check outlet temperature to ensure it does not
exceed 110°F (43°C). Make sure temperature limit
stop is properly reset to maximum 110°F (43°C)
following valve maintenance or repair. Tampering
with limit stop in any way may result in scalding
temperature causing serious bodily harm and/or
death.
Periodic Inspection/Maintenance: OPERATION
OF EMERGENCY VALVES AND FIXTURES SHOULD
BE TESTED WEEKLY PER ANSI Z358.1. In addition
conduct an annual maintenance program by a
licensed plumber or a qualified service techni-
cian to ensure proper operation of the critical
components. Regular checking and cleaning of the
thermostat assembly assures proper product func-
tion. Corrosive water conditions, temperatures over
210°F, unauthorized adjustments or repair could
render the valve ineffective for the service intended.
