Maintenance
Regularly vacuum the right side of the air cooled
condenser with a brush to remove all loose dust and
dirt. Be careful not to damage the ns.
Cubed ice machines of this type make ice that is
more pure than the water supplied to it. Since the ice
has fewer impurities, the water that remains in the
reservoir has more. The water system dilutes that
concentration but eventually it does build up and need
to be removed. Over the years it has been determined
that the typical scale removal frequency is about 2
times per year.
To remove scale from the water system.
