Condensation
If the unit is suddenly taken from a cold to a warm location,
or if ambient temperature suddenly rises, moisture may
form on the outer surface of the unit and/or inside of the
unit. This is known as condensation. If condensation
occurs, turn off the unit and wait until the condensation
clears before operating the unit. Operating the unit while
condensation is present may damage the unit.
Periodic Maintenance

information about the operational history of the unit. The
information can be displayed by text superimposition on
