integral convenience receptacles as this can result in a risk of
fire or electric shock.
18. Object and Liquid Entry – Never push objects of any kind into
the appliance through openings as they may touch dangerous
voltage points or short-out parts that could result in a fire or
electric shock. Never spill liquid of any kind on the appliance.
19. Servicing – Do not attempt to service the appliance yourself as
opening or removing covers may expose you to dangerous voltage or other hazards. Refer all servicing to qualified service personnel.
20. Damage Requiring Service – Unplug the appliance form the
wall outlet and refer servicing to qualified service personnel under the following conditions:
A. When the power-supply cord or plug is damaged,
B. If liquid has been spilled, or objects have fallen into the appliance,
C. If the appliance has been exposed to rain or water,
D. If the appliance does not operate normally by following the
operating instructions. Adjust only those controls that are
covered by the operating instructions as an improper adjustment of other controls may result in damage and will often
require extensive work by a qualified technician to restore
the appliance to its normal operation,
E. If the appliance has been dropped or damaged in any way,
and
F. When the appliance exhibits a distinct change in performance
– this indicates a need for service.

21. Replacement Parts – When replacement parts are required, be
sure the service technician has used replacement parts specified
by the manufacturer or have the same characteristics as the original part. Unauthorized substitutions may result in fire, electric
shock, or other hazards.
22. Safety Check – Upon completion of any service or repairs to
the appliance, ask the service technician to perform safety checks
to determine that the appliance is in proper operation condition.
23. Wall or Ceiling Mounting – The appliance should be mounted
to a wall or ceiling only as recommended by the manufacturer.
