reference the required flow rate to activate the unit.

Measuring Flow Rate:

1) “EFT” requires at least 0.9 gallons per minute to switch on.

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 the 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 then the flow rate would be
Flow Rate (gpm)=v/t x 60 = 1 gal./87 seconds x 60 seconds/1 minute=.69 GPM

If there is insufficient water flow to activate the unit, then you must provide more water to the
system by

opening the valves fully.

If there is sufficient water flow and still no indicator lights, then proceed to the next step.
