The indicator light does not illuminate (When the hot water faucet is fully
opened):
STEP ONE:
Is the circuit breaker switched ON at the main circuit breaker panel?
YES
Go to Step two
NO
Run water at the hot water faucet, for a couple
of minutes, before turning on the circuit
breaker. Then turn on the circuit breaker at the
main circuit breaker panel.
STEP TWO:
The unit will not heat unless sufficient water is flowing through the unit.
The minimum acceptable flow rate is about 0.5 gallons per minute (1/2
gpm). Measure the flow rate using the following procedure:
Fill a 1-gallon “milk” container and, using only water from the hot water
outlet, record the time (In seconds) required to fill. To calculate flow
rate, divide the number of gallons the container holds (In this case one
gallon) by the time required to fill.
e.g. If it takes 87 seconds to fill the container the flow rate would be:
Flow rate(gpm) = v/t x 60 = (1 gallon/87 sec.) x (60 sec./1 min.) = .69 gpm
Now, run the water with the faucet open fully. If the indicator light still does not
illuminate, then proceed to STEP THREE.
Aerator - Fits on the orifice of the faucet.
Male/female threaded adapter on top of
aerator.
Flow restrictor - (may be removed to
increase flow)
