REFRIGERATION REFRIGERATION HEALTH CHECK
Cleaning and Maintenance Guidelines Unlike almost any other piece of commercial food equipment, it is essential that all refrigeration works to a maximum efficiency 24 hours a day. Refrigeration that doesn’t operate to high standards can lead to a long list of performance issues that could potentially affect the finances and reputation of your business.
CLEANING COMMERCIAL REFRIGERATION
As commercial refrigeration is designed to preserve food and drink products, it is important to keep it clean for reasons of hygiene and health as well as longevity. Whilst the appliances are thoroughly cleaned before delivery, we recommend, that you clean the interior of the appliance before use. Before cleaning the appliance make sure the power cord is disconnected.
Cleaning the Interior and Exterior of the appliance • Do not use solvents or thinners • Do not use water jets or direct water on appliances
Before cleaning: remove all food and packaging debris. Cleaning products: only use water and non-abrasive neutral detergents. Cleaning method: use a cloth or sponge moistened with a suitable cleaning product to clean the interior. and exterior parts of the cabinet. Do not saturate the cloth or sponge. Sanitation: do not use substances that could alter the taste and smell of stored food. Rinsing: use a clean cloth or sponge moistened in clean water. Frequency: cleaning should take place at a minimum of once a week or at more frequent intervals in accordance with the type of cabinet and food product being stored or displayed.
Cleaning the Condenser The condenser is an important part of the refrigeration system. The condenser will work less efficiently if it is obstructed with any objects, therefore, it must be cleaned at least once a month. Failure to maintain the condenser will also invalidate the manufacturer’s warranty. Before cleaning the condenser switch off the appliance, disconnect the power cord and proceed as follows: • Counter and Display Refrigeration: open the control panel by slackening the screws and gently pulling down on its hinges or away from the cabinet. Be careful not to display wires or switches.
• Top-mounted unit: for units with fixed upper front panel, use a safe step ladder for direct access to the condenser located at the top of the appliance.
• For with cabinets with overturning upper front panel, unscrew the fixing screw and turn the upper panel on the top hinges. Again. take care not to displace wires or switches. Take care not to trap wires when replacing control panels.
Use an air jet or a dry brush and, working with up and down movements, remove any dust or fluff that has deposited on the heat exchanger fins. An upholstery brush attached to a vacuum cleaner nozzle is ideal. In case of greasy deposits, use a brush soaked in benzene or alcohol.
During this operation, it is advisable to use the following personal safety features: safety glasses, dust mask, chemical resistant gloves when using benzine or alcohol.
Start the appliance after cleaning and check that the cabinet is operating effectively.
MAINTAINING AND SERVICING COMMERCIAL REFRIGERATION Periodical Checks The following areas of the appliance or component assemblies require weekly checks: • condition of the condenser unit and sufficient airflow • condition and efficiency of the door sealing elements • condition of shelves in contact with food products • condition of hinges and correct fixing of the doors • condition of electrical cables and electrical parts • position of the refrigerated appliance
