8.10 Shut-Down
Occasionally it may be desirable to shut down the unit completely for a seasonal pause or for maintenance on
the electrical or hydraulic parts.
Caution: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and
dangerous operations.
Power must be disconnected before servicing.
Verify proper operation after servicing.
To place the humidifier out of service:
• Turn the ON/OFF switch (shown in Figure 8.10) to the '0' position and visually verify the front display
goes blank;
• Turn off the external power supply to the humidifier
• Close the manual gas and water feed valves
If the purpose of shutting down is to clean the steam generator or cylinder, manually drain the unit before
removing power by depressing the manual drain switch to activate the drain pump and keeping it pressed until
the unit is completely drained of water.
In the event of a malfunction of the drain pump, it is possible to drain the water from the steam generator by
attaching a hose to the bottom drain faucet and allowing the unit to drain through it.
Note:
It is advisable to drain the unit during long periods of shutdown to help prevent corrosion and buildup
of hard water in the boiling cylinder.
