4.4.2. Checking temperature settings
1.
Press the SET key briefly.
Setpoint value appears in the display.
The normal temperature view also reappears if you do not touch any button for five (5)
seconds.
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.
