4) COMMISSIONING THE HEATER
BEFORE SWITCHING THE ELECTRICAL BREAKER “ON”, MAKE SURE
THE INLET AND OUTLET BALL VALVES ARE FULLY OPEN AND WATER
IS FLOWING THROUGH ALL POINTS OF USE FOR A MINUTE OR TWO
UNTIL THE FLOW IS CONTINUOUS AND FREE FROM AIR POCKETS.
DO NOT SWITCH THE BREAKER “ON” IF THERE IS ANY POSSIBILITY
THE WATER IN THE HEATER IS FROZEN.
After verifying the heater has been
purged of air (see above) turn the circuit
breaker/disconnect “ON” and observe
the start-up sequence on the display.
The LCD screen will display the SETPOINT
TEMPERATURE in degrees F.
Below the display are 4 push buttons that
are used to control the function of the
heater. Press the UP or DOWN buttons to
establish your desired temperature. Refer
to the CONTROL FEATURES section of this
manual for additional information.
The heater is fully installed and ready for use.
