Powers ETV400 Emergency Tempering Valves with Internal Cold Water Bypass - Manual

HydroGuard ® XP Emergency Tempering valves thermostatically blend hot and cold
water to deliver tepid water to emergency fixtures, quickly compensating for tem-
perature 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.

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) fol-
lowing valve maintenance or repair. Tampering with
limit stop in any way may result in scalding tempera-
ture 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 con-
duct an annual maintenance program by a licensed
plumber or a qualified service technician to ensure
proper operation of the critical components. Regular
checking and cleaning of the thermostat assembly
assures proper product function. Corrosive water
conditions, temperatures over 210°F, unauthorized
adjustments or repair could render the valve ineffec-
tive for the service intended.
