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.
