OPERATION
After Hours
Ideally, cabinets should not be turned off after hours or
at night.
Pull down the night blind, if fitted, and turn off the
lights.
If the cabinet is turned off, transfer the products to a
cool store. When the cabinet is turned on again, allow
it to run for 30 minutes before returning the chilled
products.
Cleaning
It is recommended to clean cabinets at the end of the working day, since they
need to be shut down for this. See Cleaning section.
De-frost Cycle
Defrosting of the evaporator coil is fully automatic, taking place every two hours.
If you suspect that the defrost system is not working properly, have it checked
by a qualified service person.
Operators must not attempt to adjust the refrigeration controller.
Temperature
Checks
Cabinet temperatures should be routinely checked, to confirm satisfactory
operation.
The refrigeration controller shows the temperature of the circulating air, as it
enters the cooling coil. This will be slightly higher than the air temperature in
the display area, so a temperature probe should be used to check product
temperatures.
To avoid misleading temperature measurements, do not take a reading within
20 minutes of a defrost cycle.
