AFTER TIGHTENING BOTH FITTINGS AT THE WATER HEATER, PRIOR TO TURNING ON THE
POWER OF THE WATER HEATER, OPEN SEVERAL HOT WATER FAUCETS AND ALLOW WATER
TO RUN THROUGH THE WATER HEATER FOR A MINIMUM OF 3 MINUTES. This process purges all
air from the water lines and the heater.
Connect the cable to the terminal blocks, please notice the guidance logo below the terminal blocks.
The unit will be connected to circuit breakers as per table 1
10.

Shower (1.5 gpm) ― Sink Faucet (1.0 gpm) - All data above are based on water leaving temperature 105º F (40º C). 1.5 gpm showerhead flow rate;
1.0 gpm sink faucet flow rate, and adequate water pressure @ 60 psi. Actual performance may be altered by variations from these parameters.
For voltages less than 240 V the heating capacities will vary and it would be necessary to consider a higher capacity model.
