Flushing the Line:
•
Before connecting the copper pipe to the water heater, it is extremely important to
flush the lines to eliminate all plumbing paste, residue, or debris in the lines and
damaging the flow meter.
•
After completing plumbing installation, open the hot water faucet and allow water
to run through the water heater for at least three (3) minutes, cycling the flow on
and off every minute. This process clears all the air from the lines and must be
performed prior to turning on the power at the unit.
WARNING: FAILURE
TO DO THIS MAY DAMAGE THE FLOW METER AND/OR HEATING
ELEMENTS AND WILL VOID YOUR WARRANTY.
Checking for Leaks and Purging Air:
•
Verify circuit breakers and service disconnect supplying power to the unit are
turned off.
•
Open all hot water taps supplied by the unit and inspect water connections for leaks.
•
With all hot water taps still open, allow the water to run for a minimum of 3
minutes.
Inspect each tap to ensure all air in the lines has been purged. This process
purges all the air from the water lines and MUST be performed prior to turning on the
power at the unit.
