5.19 Anti-Snow Coverage Function
5.19.1 Anti-snow coverage function
This function prevents snow coverage on the exhaust port on top of the
product during the winter time by automatically operating the fan
periodically.
When there is a possibility of snow coverage due to changes in the
installation or operating environment (e.g. season, weather), set this
function ON in advance.
● During the product operation
The fan repeats operation with the maximum rotating cycle for 1 minute
and with the normal rotating cycle for 29 minutes.
● During the product stoppage
The fan repeats operation with the maximum rotating cycle for 1 minute
and operation stop for 29 minutes.
When the anti-snow coverage function is set ON, this function keeps
operating and rotates the fan in the way shown in "During the product
stoppage" above even when the compressor and/or pump stops operation
due to any alarms.
Keep the power supply ON for this function.
This function does not operate when the power is OFF.
This function does not operate for water-cooled type.
When the amount of snowfall on the product is too large,
snow-coverage may not be avoided completely.
When the [RUN/STOP] key is pressed during automatic operation of
the fan, it is possible to start/stop the product operation, but it is not
possible to start/stop the automatic operation of the fan.
To stop the fan, turn the power supply OFF or turn this function OFF.
