Pre-Installation Information
Bradley Freeze and Scald Protection Valves may serve as primary protection on untraced systems or a
fail-safe back-up for traced water systems. The freeze protection valve activates at 45° F (7° C) and
will fully open at 35° F (2° C). The scald protection valve activates at 85° F (30° C) and fully opens at
100° F (38° C). The freeze valve closes at 45° F (7° C) and the scald valve closes at 85° F (30° C).
These valves allow water to circulate inside the unit without getting too hot or freezing. Water drains
from the valve outlet to the outside of the unit through a hose or piping. Max. pressure rating is 200 psi.
WARNING
Read this installation manual completely to ensure proper installation, then file it
with the owner or maintenance department. Installations shown throughout this
manual are typical. Never undersize installations. Compliance and conformity to
drain requirements and other local codes and ordinances is the responsibility of
the installer.
Separate parts from packaging and make sure all parts are accounted for before
discarding any packaging material. If any parts are missing, do not begin
installation until you obtain the missing parts.
Flush the water supply lines before beginning installation. Main water supply to
Bradley drench showers, eyewashes and combination units should be “ON” at all
times and provisions shall be made to prevent unauthorized shutoff. Flushing
fluid should be tepid per ANSI Z358.1. This equipment should be inspected
annually to ensure compliance with ANSI Z358.1.
Never insulate or heat-trace the valve body. Never place the scald valve in the
shade or in a cool place by comparision with the shower head, etc. The valve
must heat to sense over-temperature line flow and then open. Temperature
control point is factory set and sealed. Do not adjust; tampering with valve set
point or cap will void warranty.
Workers who may come in contact with potentially hazardous materials should
be trained regarding the placement and proper operation of emergency
equipment per ANSI Z358.1.

FREEZE VALVE ONLY:
Remove the old ball
valve and install the
new ball valve.
NOTE: When the valve is
in the closed position,
make sure the ball weep
hole points toward the
eyewash bowl.
B
Install the freeze or scald protection
valve at a low point or where the water
will tend to be static or "dead leg."
DUAL VALVE INSTALLATION: Make
sure the freeze valve is connected
closest to the ball valve.
NOTE: Point the valve(s) downward to
allow for drainage (the flow should be
in the direction shown on the valve's
nameplate.
IMPORTANT
To prevent an ice patch hazard, Bradley
recommends that discharge from the valve be
directed through a hose or piping to the waste.
Discharge hoses or piping should be short so
that there is no standing water that may freeze.
To prevent restriction in the tube, make sure
the pipe tie straps are snug around the tube
and piping but not overtightened.

Maintenance
The Freeze protection and scald protection valves should be inspected each year. The following field
test should be performed once a year to ensure proper opening and closing of valve:
To Test the Freeze Protection Valve
Cool the valve with CO2or ice and water slurry. The valve will start to drip until warm water
reaches the actuator.
To Test the Scald Protection Valve
Heat the inlet line and valve with an electric heat gun or torch (if explosion hazard permits). Heat
until the valve flows to purge hot water.
PROBLEM CAUSE SOLUTION
Freeze protection valve is
flowing water
• Make sure the unit is supplied with tempered water• Water supply is too cold
• Replace the freeze valve
NOTE: A water supply that is at least 45°F (7°C) or
colder will hold the freeze bleed valve open. To close the
valve, increase the surface temperature of the valve to
above 45°F (7°C) by immersing the valve in hot water.
• Defective freeze valve [if the
water temperature from the valve
is above 45°F (7°C)]
• Replace the scald valve
• Defective scald valve [if the
water temperature from the valve
is below 80°F (27°C)]
• Cool the unit• Direct sunlight or high ambient
temperature
Scald protection valve is
flowing water
