The air cooled condenser should be cleaned regularly. A dirty condenser restricts air flow, causing decreased refrigeration efficiency. (Clean every month or as required).

With main power supply disconnected, remove louver grill from front of lower cabinet. Most dirt will collect on the air intake side of the condenser. This is opposite the fan motor.

Use a bristle brush to loosen the dust and dirt and remove with a vacuum cleaner. When cleaning condenser line beware of fin edges as they are sharp.

If the merchandiser is located in an area susceptible to grease collecting on the condenser, scrub with a solution of warm water and detergent. Care should be taken to keep solution away from wiring and electrical components.

Take the fan guard out for fan blades and condenser shroud cleaning, then re-install the fan guard (optional).

Check for loose items before replacing panel.
