Decommissioning and Refrigerant Handling
• Only trained technicians familiar with the appliance should perform the decommissioning pro-
cedure.
• Before removing refrigerant, take samples of refrigerant and oil for potential future analysis.
• Ensure electrical power is available before starting the procedure.
• Use recovery equipment that is in proper condition, follows manufacturer guidelines, and is
suitable for all types of refrigerants, including ammable ones.
• Recovered refrigerant must be:
-Returned to the supplier in the appropriate recovery cylinder.
-Documented with a proper waste transfer note.
-Never mixed with other refrigerants in recovery units or cylinders.
General Safety Instructions:
• All maintenance staff and nearby personnel must be informed of the nature of the work being
performed.
• Avoid working in conned spaces whenever possible.
• If hot work (e.g., welding, soldering) is required on refrigerating equipment or associated parts,
ensure suitable re extinguishing equipment (such as dry chemical or CO₂ extinguishers) is
readily available.

the unit with contents.
• Blocking the air ow may cause a decrease in performance.
• For the best performance, maintain at least 4 inches of clearance between the con-
tents and the air duct.
Temperature controller:
• The controller is located at the right, front corner.
• Do not leave the unit door open for a long period of time. For the most ecient
operation, close the door immediately after use.

Maintanence
Cautions for cleaning:
• Unplug the power cord before cleaning.
• Do not unplug/plug the power cord with wet hands.
• Do not use an abrasive cleaners, solvents or polishing agents on plastic parts. Doing so might
cause cracking or discoloring.
When it is not in use:

odor.
Maintenance
• Regular cleaning of the freezer is essential. Before cleaning, disconnect the power, empty the
appliance, and wipe the interior with water or a mild detergent.
• Avoid the use of harsh chemicals such as boiling water, acids, strong solvents, petroeum-based
products, or abrasive powders.
• After cleaning, thoroughly dry the interior and exterior surfaces.
• To maintain the door seal and prolong its life, lightly apply talcum powder to the seal after it
has dried naturally.
• For external surfaces, use a soft cloth dampened with water or a small amount of detergent.
Ensure that the power source is not exposed to water during cleaning.
