Condair US 13, Operation And Maintenance Manual

Page: 37 / 74

To restart the unit:
1.
Examine the humidifier and other system components for damage. Check for loose or damaged electrical
connections, and ensure that the humidifier and its components have not shifted from their mountings, and
are securely fastened.
2.
Turn on the water supply to the humidifier and check for leaks.
3.
Reinstall and secure any removed door panels.
4.
Remove the lock and tag from the external disconnect switch, and restore power to the humidifier.
5.
Press the On/Off button to the On position.
The humidifier will power up and remain idle until a humidity demand signal is received.
7.4 Shutting Down the Unit
Strictly observe all safety precautions and perform only the tasks described in this manual. Refer to "For Your
Safety" on page 9 .
IMPORTANT! Avoid unpowering your unit. To stop humidification, set your demand to 0. This will leave your
unit powered and in 'standby' mode to allow your unit to flush regularly and prevent microbial growth.
To shut down the Ultrasonic Humidifier:
1.
Shut off the water supply to the humidifier.
2.
Make a note of the fault code, if any, displayed on the Home screen.
3.
Set the On/Off button to the Off position.
4.
Wait for the humidifier to drain the reservoir and shut down. The drain valve will remain open for 70
seconds to drain the unit. After this period, the drain valve will close.
5.
Disconnect the power supply to the humidifier at the external disconnect switch. To prevent accidental
power-up, lock out and tag out.
7.5 Remote Monitoring
The Ultrasonic Humidifier can be monitored remotely by connecting the fault relay to a remote monitoring system.
7.6 Draining the Unit
To drain the reservoir:
1.
Turn off the humidifier by pressing the On/Off button at the front of the unit. Refer to "User Interface
Controls" on page 24 . The drain valve will open and remain energized for 70 seconds to fully drain the
reservoir (independent of the current water level in the unit).
During a flushing cycle, the unit will drain from full. If the water level sensor indicates a full tank after 70 seconds
has passed, the unit will enter a Drain Fault and stop operating.
Note: There is no manual drain valve. The drain valve is operated with electricity and is normally closed. In
addition to its main power source, it is also powered by the back-up battery (when the mains power is not
available).
Ensure that the back-up battery is installed and fully functional
or the unit will not drain
during an outage, and will create stagnant water.
