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.

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.
