COMMISSIONING YOUR HEATER
IMPORTANT
Before switching “on” the power at the main circuit breaker panel make sure that the hot
water circuit is free of air pockets or premature failure of the heating element will occur.
To do this open all hot water fixtures one at a time for several minutes until the water flow
is continuous and free from “gulping” and from visible air pockets.
1) With inlet and outlet BALL VALVES fully open, turn on a hot water outlet.
2) Run for 3 minute.
3) Switch on electric supply at circuit breaker panel.
4) The power indicator lights should now come on.
NOTE: At this point water temperature may not be hot.
5) Using the OUTLET BALL VALVE slowly reduce water flow until desired temperature is
achieved at hot water outlet.
NOTE: The water temperature is regulated by the flow through the heater. The lower the
flow the higher the temperature and vice versa.
6) If temperature does not achieve desired temperature, please call technical services.
