Dry Gaskets and Heat
Breaks
Thoroughly dry the door and chamber opening gaskets and
heat breaks after each run using a soft cloth to prevent ice
build-up which could reduce the effectiveness of the door
seal. Immediately clean up any water that may drip onto the
floor in order to prevent a potential slip or fall hazard.
Disinfect Controlled-Rate
Freezer Interior
Use an appropriate disinfectant. All articles and surfaces to be
disinfected must be thoroughly cleaned, rinsed and rough
dried.
1. Shut down the freezer using soft shut down button Turn
the freezer off and disconnect the plug from the power
source.
2. Unplug and remove the Sample probe from the chamber,
clean with alcohol and allow to dry.
3. Wash the cabinet interior using a non-abrasive cloth and
disinfectant starting at the top and working down. The
cabinet and door must be rinsed with sterile water until
the disinfectant has been removed. After the cabinet has
been rinsed, spray with 70% alcohol.
4. Allow the cabinet door to remain open for the alcohol to
evaporate.
5. Plug the freezer in and turn the power switch on.
Clean a Major Spill in the
Chamber
1. Remove the two screws at the top and bottom of each
side, securing the screened side ducts to the chamber.
Set the ducts aside.
2. Press the top and bottom edges of the center duct
toward each other and draw the duct outward to remove.
3. The chamber is now fully accessible and can be cleaned.
4. Clean the interior of the unit with an appropriate
disinfectant. Clean, rinse and wipe dry, as needed. Clean
the screened side ducts and center ducts before
reinstalling.
5. Press the top and bottom edges of the center duct
toward each other and insert the duct into the center of
the chamber. The edges fit inside the door gasket.
6. Install each screened side duct. Locate the tabs on the
back of each duct into the proper holes at the back of the
chamber. Align the two screw holes and secure at the top
and bottom of each side.
WARNING:
Be sure to shut down the unit using
shut down button (
) to disconnect the
unit from the power source before beginning of
any service work.
CAUTION:
Before using any cleaning or
decontamination method except those
recommended by the manufacturer, users must
check with the manufacturer that the proposed
method will not damage the equipment.
CAUTION:
Do not use strong alkaline or caustic
agents. Stainless steel is corrosion-resistant, not
corrosion-proof. Do not use a solution of sodium
hypochlorite (bleach) as it can cause pitting and
rusting.
WARNING:
Alcohol, even a 70% solution, is
volatile and flammable. Use it only in a well
ventilated area that is free from open flame. If any
component is cleaned with alcohol, do not
expose the component to open flame or other
possible hazard. Allow the alcohol to fully dry
before turning power on.
WARNING:
Be sure to shut down the freezer
using soft shut down button and turn the unit
circuit breaker off and disconnect the unit from
the power source to prevent the chamber fan
from starting unexpectedly while the duct sheets
are removed for cleaning.
