Once the shut-down has occurred this product will reduce the
flow of hot water to a trickle. This continuation of water flow is
necessary to allow resetting to occur.
• It is recommended that this product be tested monthly.
RESET:
• When ShowerSafe

shuts down the hot water flow, turn off the
hot tap, stand clear of the flow and open the cold tap.
ShowerSafe

will reset as soon as the hot water is purged from
the pipes.
• Turn on the cold water to achieve the desired flow rate, then
introduce hot water until the preferred temperature is reached.

WARNING
• This product is designed to reduce the incidence of scalding;
however hot water will trickle from the unit when shut-down
occurs.
• Shower fittings fitted with this product should not be operated
by children without parental supervision.

FUNCTION:
Storage hot water systems should deliver water at a
minimum of 140°F to prevent bacteria growth. However at
this temperature it takes one second for a severe burn or
scald to occur!
ShowerSafe

is designed to ensure water is delivered at a
temperature of not more than 120°F. Providing it is
correctly installed and operated, the bath water
temperature cannot exceed this temperature, thereby
protecting individuals from hot water burns. Its quick shut-
down action also assists in prevention of scalding should
the hot tap be accidentally turned on.
OPERATION:
For normal operation, first turn on the cold water to
achieve the desired flow rate, then introduce hot water
until the preferred temperature is reached.
TEST:
• When testing, ensure that no person is in the line of
flow of water or in the catchments of the water.
• Have a strong flow of warm water pass through the
shower fitting, then close the cold tap & observe the
water shut-down.
