stop.
Other than emergency situations, do not shut down the
system by de-energizing the main power disconnect. De-
energizing the main power disconnect will cause all
components to immediately shut down and power to be
isolated. A hard shut down will damage the system, as
the components will not be cooled down in a controlled
manner.
5.8 LONG-TERM SHUTDOWN
If the machine will be turned off for a long period of time, some special precautions must
be taken to protect the HoneyCombe
®
wheel. Even when the machine is shut down,
moist air can continue to move through the wheel. This is especially likely if a fan or air
moving device is still operating in the system. Eventually, a large amount of moisture can
collect in the wheel. This can damage the wheel. For instructions on long-term
shutdown, see Section 6 - MAINTENANCE.
5.9 HMI (OPTION)
If the HMI has been purchased, it will be located on the front of the electrical enclosure. Once
energized, the display will show that the machine is ready to run. Note there are two lines at
the top of the screen. The upper line (React) refers to just the dehumidifier itself. The lower
line (Status) refers to the entire system. See Figure below:

This refers to just the dehumidifier itself (heater, reactivation fan,
drive motor, etc.).

One the line for “React”, there are four possible indications:-
