Important Notes About Water Connections:
1.
All water pipe must comply with national and applicable state and local water
pipe codes.
2.
A pressure relief valve must be installed if the cold water supply pressure
exceeds 150PSI.
3.
The unit should be connected directly to the main water supply. Flush pipe with
water to remove any debris or loose particles.
4.
All connections to the unit should be ¾” NPT. Larger pipe can be connected but
the appropriate adapters must be used.
5.
Please remember to install rubber seal rings at the connections. When all water
connections are completed, check for leaks and take corrective action before
proceeding.
How the Unit works
1.
This unit heats water instantaneously as it flows through the heating elements.
2.
The electronic control monitors the flow rate and the incoming water temperature
and then switches on the required number of heating elements to reach the set
temperature.
3.
The outlet water temperature will be higher than the setting if the minimum flow
rate isn't met. The outlet water temperature will be lower than the setting if the
maximum flow rate is exceeded.
Using the Water Heater - Operation Instructions
