OPERATIONS (Continued):
System Start-Up:
1) Turn on water at its supply source. Allow water to flow for several minutes to insure
that all entrapped air has been purged from the heating column(s).
2) Stop water flow at point of use location and check all plumbing connections and
water heater for leaks. Repair any water leaks if applicable.
3) Enable the power at the MAIN SERVICE DISCONNECT (provided by customer).
4) Ensure that the disconnect handle on the front of the unit (if provided) is ON and the
EMO button on the front panel is not depressed.
5) Turn the CONTROL POWER toggle switch to the ON position. At this time the
temperature controller and all optional displays will come on.
Note: Temperature controller set point should be set to "0" at this time to
prevent accidental heater engagement during calibration procedures. Reference
temperature controller section if required.
6) Adjust the setpoint of the temperature controller to the desired value.
7) Turn the ENABLE HEATER switch past the ON position to the RESET position, then
release the switch, which will move to the ON position. If all criteria for the various
safety devices have been met, the heater will begin to heat.
System Shut-Down:
1) Turn the ENABLE HEATER switch from the ON position to the OFF position.
Continue water flow through the heater until the outlet temperature display indicates
95°F (35°C) or less.
2) Turn the CONTROL POWER toggle switch to OFF.
3) Turn off the MAIN SERVICE DISCONNECT to the unit (provided by customer).
4) Stop water flow through the unit. If the shut down will be for an extended period,
open the customer supplied drain located near the inlet plumbing connection to drain
the water from the unit. Once the unit is drained, dry the unit by blowing inert gas
(N2 or CDA) through the piping system.
