4.5. Automatic defrosting
The cabinet is equipped with an automatic defrosting equipment. The control device of the
cabinet controls the operation periods and the defrosting process. Defrosting is performed six
(6) times a day (electric defrosting). Drain water from defrosting is automatically led to a hot
gas evaporation tray or to an electrically heated evaporation sump depending on the cabinet
model. The temperature inside the cabinet rises by a few degrees during defrosting.
5. Cleaning
The following cleaning procedure must be carried out at least twice a year.
NOTE The cabinet must not be cleaned while the fans are running. To disable the
fans, disconnect the cabinet from the electricity supply.
WARNING Evaporators, condensers and parts made of stainless steel may have sharp
edges. Wear protective gloves and work cautiously to avoid cut injuries.
1. Disconnect the cabinet from the mains supply or turn the separate switch to the cleaning
position.
2. Empty the cabinet.
3. Allow the cabinet to reach the ambient temperature.
4. Remove any debris.
Do not use picks or sharp tools to remove ice from the evaporator. Damage to the coil may
lead to refrigerant leakage.
5. Inspect for drain water and remove it, if there is any.
6. Clean the interior surfaces of the cabinet with a mild liquid detergent (non-toxic, pH 6-8)
and dry the surfaces carefully using a clean towel.
7. When cleaning is completed, start up the cabinet.
See section Starting up.
Check at regular intervals also that
• the operating noise of the cabinet is normal,
• the evaporator is clean and
• the inlet and outlet grids are not obstructed or dirty.
NOTE Clean the drain sump located in the machinery compartment. Inadequate or
infrequent cleaning may shorten the service life of the electric heater / hot gas
piping for the drain sump. Detergent residues must be cleaned without delay
from the tray.
NOTE
In the event of a refrigerant leakage all products displayed in the cabinet must
be disposed of and then the cabinet must be cleaned.
