Maintenance

Cleaning

The appliance casing can be cleaned
using a damp cloth and a mild deter-
gent. Do not use abrasive cleaners.

Inspection and maintenance

To ensure continued efficient opera-
tion of the appliance, it is recom-
mended that it is checked and
serviced at regular intervals. The fre-
quency of servicing will depend upon
the particular installation conditions
and usage but in general once a year
should be adequate. The law requires
that any service work must be carried
out by a competent CORGI registered
engineer.
