The air condenser should be kept clean to ensure the appliance's perfor-
mance and efficiency, as air should freely circulate inside the appliance.
The condenser should therefore be cleaned every 30 days, using non-
metal brushes to remove all dust and dirt from condenser blades.
–Access to the condenser is from the front.
–Unhook the front guard, pulling it towards you.
The appliance has been tested before being put into service.
The information provided below is intended to assist in the identification and correction
of any anomalies and malfunctions which might occur during use.
The user can solve some of these problems himself, but for others specific technical
knowledge or skill is required, and so they must only be carried out by qualified staff
with recognised experience acquired in the specific sector of operation.
