6.5 Cleaning the Door Gasket
Routinely (monthly) check the door gasket for any perforations that will cause air
leaks. Frost will form around all leakage areas. Frost accumulation on the door gasket may
be removed with a soft cloth.
6.6 Cleaning the Vacuum Relief Port (Refer to Figures 6-1 and 6-2 also Figures
4-5 and 4-6)
The vacuum relief port on the Model 8500 Series freezers is located in the lower
left front of the chamber interior. Routinely check the vacuum relief port for frost
accumulation and clean as necessary, using a soft cloth.
The vacuum relief port contains a small heating element to
reduce frost build-up. If the freezer is not disconnected from the
electrical supply or turned off at the power switch, the heating
element will continue to operate and may cause injury to personnel
cleaning the freezer chamber.
