Note: This operation must be carried out monthly with the display disconnected from the electrical supply.
supply.
•
If your display is fitted with a full height sneeze screen, you will need to remove it before attempting to carry out this
cleaning operation.
•
Lift out the main display deck sections and set aside. This will expose two separate metal plates, one of which supports
the air circulation fans and the second is a baffle plate guiding the air through the main cooling coil.
•
These plates are secured by finger-tightened screws, which are removed without tools.
•
Once the screws have been removed the fan mounting plate can be lifted out taking care not to strain the wiring, the
coil cover plate can then be removed and the main cooling coil exposed.
•
Remove any food debris using a vacuum cleaner followed by a cloth and detergent.
•
Wipe the fan blades using a damp cloth and detergent.
•
Finally spray the interior of the tank and the finned cooling coil generously with a sanitising solution such as Dettox.
Avoid using excess water if your unit is not connected to a plumbed drain, as this may cause the automatic evaporating
drip tray to over flow.
•
Re-assembly is the reverse of the above.
When cleaning the unit you must inspect the main cooling coil. You should find the coil covered with a thin layer of frost or
ice. Anything up to about 2mm thick is quite normal but anything in excess of this seriously impairs its efficiency.
If there is a build up of ice refer to section 3.1.
