Perform Operational Test No. 1
A
Set the 2 or 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 .5gpm
(1 .9 lpm), the flow switch recognizes this
condition and begins the heating process .
When the flow switch activates:
• The display changes from OFF to the output
temperature, verifying power supply connection
C
to the heating elements via the triac switches .
• Element load lights may be solid or flash
in unison as heating elements modulate
depending on the hot water demand .
• Digital temperature controller shows water
temperature . Additional programming is
not necessary .

Perform Operational Test No. 2
A
Turn on hot water faucet/fixture/process . 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.

Ensure the cover is on or enclosure door is
closed prior to performing this operational test.
Press the up or down arrow keys to
D
adjust the set temperature . The controller
displays the temperature of water
measured at the outlet .
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 .
Each model has precise specifications
for temperature rise capabilities.
Turn off hot water faucet/fixture/process .
B
The flow switch will deactivate and shut
off power to the heater .
