EXTENDED SHUTDOWN

During long periods of humidification downtime, the cylinder should be completely drained and emptied.

1.  Manually push the On/Off rocker switch to drain.
2.  Wait until the humidifier is completely drained of water.
3.  Turn the On/Off rocker switch to the “OFF” position.
4.  Shut off the main external power to the humidifier unit.
5.  Turn the supply water off at the shut-off valve.

STARTING AFTER EXTENDED SHUTDOWN

1.  Inspect the humidifier for any damage. Check to make sure the mounting and installation has not been altered.
2.  Turn on the main external power to the humidifier unit.
3.  Turn the On/Off rocker switch to the “ON” position.
4.  Review and follow the startup procedure in the IOM.

CARNES RECOMMENDS THAT THE CYLINDER REMAIN EMPTY DURING EXTENDED SHUTDOWN
PERIODS. THIS WILL PREVENT THE POSSIBILITY OF CORROSION OF THE ELECTRODES AND
THE ACCUMULATION OF ALGAE AND BACTERIA GROWING IN THE CYLINDER.
