7 – Filling with products and use of the cabinet (startup)
If the island has been set at a sharp angle during positioning, wait at least three hours before starting it up to allow the
lubricating oil to collect in the compressor. If this instruction is not followed the motor-driven condenser may be damaged
beyond repair. Any swelling of the unit while working does not compromise its proper functioning.
The island may only be started up for the first time when points 3 and 4 have been completed.
With the island turned off, proceed as follows: remove the protective plastic film on the outside and then clean the unit,
following the instructions given in point 10.
Fit the plug in the socket (with the characteristics described in point 5) and operate any remote-control switch that may
have been fitted. A slight operating noise made by the motor and the display turned on indicate that the unit has been
switched on.
The display (FIG. 10) located on the front panel indicates the operating temperature of the island. The instruction booklet
of the electronic controls, to which the display refers, is enclosed with the instruction manual (this device cannot be
tampered with due to a safety password that only a specialized technician can change).
The unit starts its cooling cycle after it has been switched on. The product can be loaded when the temperature shown on
the display is -18°C for frozen packed foods and -20°C for ice cream.
The unit has been designed to display packed foodstuffs, it must maintain the temperature of the product and must not
lower it, and consequently, the product must only be placed inside the unit if it is already refrigerated and is at its
respective preservation temperature.
Bottles and glass containers or jars full of liquid must not be stored in the BT versions as they may burst.
For a correct preservation of the product, it is advisable:
- To use the special grids that are adjustable in height (when provided) to maintain the best ratio at all times between
refrigerated space and product displayed (FIG. 11).
- Never exceed the maximum load line shown on the inside of the island (FIG. 12):
- LIBRA ST: maximum load line = 30 cm by climatic class 3 (25°C RH 60%)
- When an island that is already partially loaded with goods is filled with more products (apart from adhering to the
points referred to above), it is good practice to place the new foodstuffs under the existing ones.
- Each unit is equipped with sliding covers in low-emissivity glass. These are necessary for the proper working, they
must be kept closed and they can be opened only to fill up and take out the products.
The plug-in islands are provided, as a standard fitting, with an electronic control. The thermostat adjustment and the
amount of gas are set in the factory and any tampering with these settings will relieve the manufacturer of all
responsibility.
