MAINTENANCE
1.
This can only be done by an authorized service agent such as your local
Sealer dealer or any agent qualified to undertake electrical repairs.
2.If the unit requires external cleaning make sure it is switched off and
unplugged from the mains supply. Use a soft tissue or cloth for general
cleaning. To remove more persistent dirt or grime wipe down with a cloth that
has been dampened with warm soapy water. Do not use any solvents ( such
as thinners ) as these may damage the plastic casing.
