3.Check all wiring connections.

4.Check electrical input.

5.Check the standard pressure in the refrigerant system.

6.Perform at least one blast freezing cycle (to the SET temperature) and one manual defrosting cycle. In the event that the appliance or

the remote condensing unit have not been transported in a vertical position (e.g. on the back) or have been overturned during

installation works, allow at least 4 hours before starting up the equipment.

2.8Safety and control systems

•Door microswitch: shuts down fan operation in the cabinet when the door is opened.

•General fuses: protect the power circuit against short circuiting and overloads.

•Compressor heat relay: intervenes in the event of overloads or operating faults.

•Safety pressure switch: intervenes in the event of excessive pressure in the refrigerant circuit.

•Plug fuses: intervene in the event of high pressure or operating fault in the safety pressure switch (see above).

•Chamber temperature control: operated by the electronic board by means of a probe inside the cabinet.

•Temperature control end defrost cycle: controlled by the electronic board by means of the probe in the evaporator.

3. ADVICE TO ENSURE EFFICIENT APPLIANCE OPERATION

3.1 Shut-down procedures

In the event of emergency, shut down the appliance by switching off power at the main panel, by means of a breaker or power disconnect or by removing the plug from the power socket.

3.2 Operating tips

Before starting up the appliance, clean the inside of the compartment thoroughly.

3.2.1 Pre-cooling

Before using the appliance for the first time, or after a prolonged period of disuse, precool the compartment by running an empty cycle until the set operating temperature has been reached.

To ensure optimal performance without any alteration to food quality: arrange food products in such a way as to favour the circulation of cold air throughout the compartment; open the door as little as possible.

3.2.2 Loading the appliance

a)Ensure that foods to be chilled and/or frozen are separate and do not have a thickness greater than 2’’/50mm-3’’/80mm. When chilling liquids it is recommended that you do not exceed a product thickness of 1”/25mm. It is also recommended that you stir the product every 30 minutes. Do not load the appliance beyond the quantity recommended by the manufacturer.

b)Ensure that there is sufficient clearance between trays to enable free air circulation. If the appliance is not completely full, distribute the trays and foods evenly throughout the available space.

c) Position trays inside the tray compartment as far as they will go, as close as possible to the evaporator.

d)Position the core probe at the centre of the largest product or food item; make sure that the tip of the probe does not protrude or touch the tray. If you are using the probe for a liquid ensure that the probe is placed in the warmest location in the warmest pan. The probe

must be cleaned and sanitized before each new cycle (operation) to prevent inadvertent contamination.

e)Avoid covering the trays and/or containers with insulating covers or film. The more the product is insulated, the more time is required for chilling or freezing. Trays should be packaged when the product has been chilled, before being placed in storage.
