4.4 Door Features
- Glass Doors: Double-pane thermal glass provides visibility of products while maintaining insulation.
- Magnetic Gaskets: Ensure a tight seal to prevent cold air loss.
- Door Locks: For securing contents.
- Threshold Protector: Prevents damage to the cabinet when loading or unloading heavy items like kegs.
5. Maintenance and Cleaning
5.1 Regular Cleaning
- Interior: Clean the stainless steel interior floor and walls regularly with a mild, non-abrasive cleaner and warm water. Rinse and dry thoroughly to prevent odors and maintain hygiene.
- Exterior: Wipe down the black laminate vinyl exterior and stainless steel countertop with a damp cloth and mild detergent. Avoid abrasive cleaners that could damage the finish.
- Glass Doors: Use a glass cleaner for streak-free visibility.
- Door Gaskets: Inspect and clean door gaskets regularly to ensure they are free of debris and maintain a proper seal. Replace worn or damaged gaskets promptly.
5.2 Condenser Coil Cleaning
The unit features a reverse condensing fan motor that helps remove debris from the condensing coil. This mechanism activates for 20 seconds each time the compressor turns on, directing air towards the coil to dislodge dirt and dust. While this reduces buildup, regular manual inspection and cleaning are still recommended for optimal efficiency.
- Disconnect power to the unit before cleaning.
- Access the refrigeration system by removing the front grille and sliding it out.
- Use a stiff brush or vacuum cleaner to remove any remaining dust and debris from the condenser coil fins.
- Reinstall the grille and restore power.
