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 THE HOT
WATER FAUCET FOR A MINUTE OR TWO UNTIL THE FLOW IS CONTINUOUS AND FREE FROM AIR POCKETS. DO
NOT SWITCH THE BREAKER “ON” IF THERE IS A POSSIBILITY THE WATER IN THE HEATER IS FROZEN.
1.
Make sure water is flowing through the faucet.
2.
Switch “ON” the electric power supply at the breaker.
3.
Keep water flowing through the faucet for the next
step.
4.
The display on the circuit board should come “ON”.
With the flow running, the heater will go through the 60
seconds startup/self-calibration procedure. The display will
count down from 60 to 0. When the display timer reaches
45, the unit starts heating and continues counting down to
0.
5.
After the 60 seconds in step 4, the display will show the
temperature setpoint.
The heater is commissioned at this point.
Faucet can be turned off and used as needed.
Note:
the temperature display will turn off after 5 minutes
of inactivity. Display turns on when water flows through
heater.
