c) The device must be opened by trained staff only.
d) Regard correct mains voltage.
CAUTION
Hot surface

Under normal operating conditions the aggregates are maintenance free. Preventive maintenance must therefore be routinely
carried out by the operating company.
When doing so, please pay attention to:
– Tight screw fittings,
– Tightness,
– Damage to the aggregate (replace damaged parts),
– Abnormal (unusual) noise and vibration,
– Cooler matrix cleanliness. Dirt on the cooler matrix reduces the cooling capacity,
– Check warning labels for legibility and damage.
Electrical connections must be checked annually by a licensed electrician.
The external parts the motors, particularly the cooling ribs and cooling ducts as clean as possible to prevent compromising heat
release.
Please note the specified protection against dust and moisture. Pressure cleaning is only permitted if the motor has the respect-
ive protection rating.
The motors feature ball bearings sealed on both sides. The grease filling is designed to last for the life of the unit. Greasing is not
necessary.
The motor mounts may only be replaced by Bühler Technologies GmbH or a qualified specialist company.
