Preparations
Long operation time and a temperature
increase of housing and compressor are
normal during initial operation.
Some of the sounds produced during
initial operation or at start-up will fade
during normal operation.
Attaching the toe moulding
Open the refrigerator and freezer doors, remove the
moulding from the refrigerator compartment, and then
affix it as shown in the illustration.
During initial operation, the appliance
housing may become warm to prevent
condensation.
At start-up and during operation, the
compressor may produce an audible
sound when starting or stopping
The sound of the refrigerant flowing
through the evaporator and compressor is
normal. A continuous or intermittent
flowing sound after operation is normal.
During the defrosting process, thaw
water may drip onto the heating elements,
causing audible sounds in the evaporator.
