6.1 – Caring for Your
Freezer Gasket
The temperature differential between
ambient and the ultra-low interior can attract
moisture near the gasket. For best results
always wipe away moisture during openings
to prevent ice accumulation. Do not use sharp
instruments to scrape ice from the surface.
6.2 – Air Intake Filter
Clean accumulated dust and dirt on the
air intake filter every month. Pull the filter
cover to the left as shown. Please note that it
cannot be completely removed. Gently clean
the filter with a vacuum cleaner. If there are
stubborn residues use a soft brush to work
them loose.
