OPERATION
3.1.
INITIAL START-UP
Connect the cabinet to the mains and the display will light up showing two
horizontal strips. These indicate that the control is conducting a self-test. After
approximately 5 seconds the temperature that has been read by the control will
appear on the display and the unit will actuate itself.
Check to see if the selected operating temperature is correct by pressing the “SET”
button. The selected temperature will appear on the display. If this is correct, then
the control will return to its normal position. If you wish to change the
temperature, select the temperature required using the
and
buttons and
confirm by once again pressing “SET”.
In order to obtain maximum evaporator efficiency, the thermostatic expansion
valve has to be adjusted by the installer.
The control components may only be operated by the technician
responsible for the installation. The functions available to users are
shutdown, start-up of the unit from the circuit board and the start-
up of the lighting from its corresponding switches.
The temperature control and defrost times that we recommend for each cabinet
are based on our experience and laboratory tests. Different air conditions could
require controls that are different from those recommended.

Do not load products that have higher temperatures than the
cabinet’s operating temperature;

Empty spaces should be left between products to ensure perfect air
circulation around them.
