B
Start the water flow through the heater by
starting the process or fixture this heater is
connected to in order to activate heater .
D
Press the up or down arrow keys to
adjust the set temperature . The controller
displays the temperature of water
measured at the outlet .
E
Test water temperature and stability at
outlet by viewing the display . Controller
displays (in red) the temperature of water
exiting the heater .
C
When flow rate reaches approximately
0 .75gpm/2 .8 lpm (standard), the flow switch
activates and begins the heating process .
When the flow switch activates:
• Phase indicator lights illuminate on the front
bezel verifying power supply connection to the
heating elements via the solid-state relays .
• Element load lights may be solid or flash
in unison as heating elements modulate
depending on the hot water demand .
• Lower display on controller goes from off
to setpoint temperature .
Located on the panel are two 36kW-50kW
green ready lights. When illuminated, the
safety circuit is engaged and ready for use.
Heater will not energize heating elements if the
inlet water temperature is equal to or greater than
the temperature set on the digital controller .

A
Turn on hot water faucet/fixture/process . The
heater should activate immediately .
B
Turn off hot water faucet/fixture/process .
The flow switch will deactivate and shut
off power to the heater .
If the water flow exceeds maximum heating capacity of the heater, the temperature of water at the outlet
may be lower than the temperature selected on the controller. See table below to determine maximum
temperature rise capabilities.
Each model has precise specifications for temperature rise capabilities.
