product. Any mounting of the unit should follow the manufacturer's instructions, and
should use a mounting accessory recommended by the manufacturer. An appliance and
cart combination should be moved with care. Quick stops, excessive force, and uneven
surfaces may cause the appliance and cart combination to overturn.

– Ventilation - Openings in the enclosure, if any, are provided for ventilation and to ensure

reliable operation of the unit and to protect it from overheating. These openings must not
be blocked or covered. The unit should not be placed in a built-in installation unless
proper ventilation is provided or the manufacturer's instructions have been adhered to.
Maintain a minimum distance of 2 inch (50 mm) around the front, the rear, and the sides
of the unit for sufficient ventilation.

work by a qualified technician to restore the units to their normal operation.
– If the unit has been dropped or the unit has been damaged.
– When the unit exhibits a distinct change in performance; this indicates a need for

service.

– Replacement Parts - When replacement parts are required be sure the service technician

has used replacement parts specified by the manufacturer or parts which have the same
characteristics as the original part. Unauthorised substitutions may result in fire, electric
shock or other hazards.

– Safety Check - Upon completion of any service or repairs to the units, ask the service

technician to perform safety checks to determine that the unit is in proper operating
condition.
