3.3. Automatic defrosting

Defrosting is controlled by a separate defrosting timer containing a limiter thermostat. Defrosting
lasts approximately 30 minutes and normally takes place automatically 1-4 times a day, depending
on the cabinet model. The temperature inside the cabinet rises by a few degrees during defrosting
and the evaporation fans stop.
NOTE Gusto SO cabinet does not need to be defrosted, if it is emptied and turned off for the
night.
The drain water from defrosting travels through a pipe to the sewage drain or is transferred to
the sewage drain by a separate pump. Although defrosting is automatic, the cabinet can also be
manually set to defrost. Contact your nearest servicing organisation if you need assistance with
defrosting and cleaning.
NOTE Cabinets with an integrated machinery unit have a separate evaporation sump for drain
water, which needs manual emptying. Gusto SO freezer cabinet F always requires a
cabinet-specific sewerage point for the drain water, since there is no condensate
evaporator pan. Because the cabinet's sewerage point is on a different level than in the
regular Gusto SO model, common drain water line cannot be used.

3.4. Loading cabinet

When loading the cabinet, care must be taken that the airflow is retained. Observe the loading
limits of the cabinet. Overloading or improper loading of the cabinet will disrupt the airflow and
raise the temperature of products in the cabinet.
For Luxo FGD and Nardo HGD cabinets, the door of the cabinet can be locked with a locking
latch in open position during loading. Avoid keeping the door open for long periods of time.
