Periodic servicing
Long intervals between using the machine
If the machine is not being used for a long period, the granules and the machine
should be disinfected with chlorine. You can store the granules in the freezer dur-
ing this period.
If the machine is not being used for a long period, cooking oil should be sprayed
into the pump housings. The oil will prevent rust from forming in the pump housing
and jamming the impeller. The cooking oil is sprayed into the pumps' inlet pipes.
(This should be done by an authorised engineer.)
If the machine will not be used for a longer period, the power to the machine
should be turned off using the power switch, the water supply turned off and the
door should be left ajar.
