OPTIONAL OUTLET SETUP PIPING

(BY OTHERS)

The addition of this piping arrangement (extra
tee and ball valve) eliminates the need to turn
fixtures on and off throughout the building at
setup.

The

flows

required

in

the

setup

instructions (page 3) are set by using Ball Valve
A. (make sure main outlet ball valve is closed).

CAUTION! ALL THERMOSTATIC WATER MIXING VALVES AND SYSTEMS HAVE
LIMITATIONS! THEY WILL NOT PROVIDE THE DESIRED PERFORMANCE OUTSIDE
OF THEIR FLOW CAPACITY RANGE! CONSULT THE CAPACITY CHART BELOW AND
OBSERVE MINIMUM FLOWS SHOWN.
