Perform Operational Test No. 1
Ensure the enclosure door is closed
prior to performing operation test.
A
Set the 3-pole switch or circuit breaker to the
ON position .
Start the water flow through the heater by
B
starting the process or fixture this heater is
connected to in order to activate heater .
When flow rate reaches approximately
0 .75 gpm (2 .8 L/Min), the flow switch
activates and begins the heating process .
When the flow switch activates:
• Phase indicator lights illuminate on the front
C
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 .

Perform Operational Test No. 2
Each model has precise specifications for temperature rise capabilities.
Turn on hot water faucet/fixture/process
A
(min flow rate of 0 .75 gpm/2 .8 L/Min) . The
heater should activate immediately .
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.

The controller displays the temperature of
water measured at the outlet .
Located on the panel is a (18 kW or 25 kW)
green ready light. When illuminated, the
safety circuit is engaged and ready for use.
Test water temperature and stability at
E
outlet by viewing the display . Controller
displays (in red) the temperature of
water exiting the heater .
Heater will not energize heating elements if the
inlet water temperature is equal to or greater than
the temperature set on the digital controller .
