AMX300 Series
DIRECTCONNECT™ MIXING VALVE
APPLICATION
The AMX300 Series DirectConnect™ Mixing Valves fit any
application requiring accurate control of water temperature
by mixing hot and cold water such as domestic water. The
valves are designed for mounting directly onto the water
heater in residences, hotels, schools, hospitals, or nursing
homes.
Benefits
The AMX300 valves provide increased comfort and safety for
the user, as well as reduced installation time for the plumbing
contractor.
Operation
Automatic operation is provided by a thermostatic element.
The element will control hot and cold water supply based on
valve setting. If cold water is shut off, the valve will reduce the
mixed water flow rate in seconds.
The internal parts of the valve are coated with Teflon
®
to
reduce scale build-up for better performance in marginal
quality water.
NOTE: Even with the Teflon
®
coating, the internal parts of
the valve may still suffer scale build-up and may
require cleaning periodically.
SPECIFICATIONS
CAUTION
Injury Hazard.
Exceeding recommended maximum mix temperature
can cause burns.
NOTE: If installing AMX300 Series Valve on a system using
PEX, consult PEX tubing manufacturer for maximum
allowable temperature ratings.
