Pressure differences between the inside and
outside of the upright freezer may result in
transient difficulty in door opening.
The upright freezer enclosure may emit heat during
operation, especially in summer, caused by the
radiation of the condenser; this is normal.
Condensation may be detected on the exterior surface
and door seals of the upright freezer when humidity is
high; this is normal.
The compresser may cause a buzzing sound when
starting up or shutting down.
The solenoid valve or electric switch valve may create
a clattering sound which is normal and does not
affect the operation.
