Operating instructions

Operation

Cold basin CB and frost plane FrP

Before placing products in the unit, wait until it has reached the temperature set with the thermostat.

Correct cold storage of foodstuffs facilitates kitchen activities and affects energy consumption:

• Do not load products until the appliance has reached the correct operating temperature.
• Monitor the internal temperature of the unit daily.
• Always keep the products in good order.
• Do not store spoiled food in the unit.

In normal conditions, the thermostat need not be adjusted.

Crushed ice basin CIB

Before loading the products, put crushed ice or cold bed in the basin. Points to be observed in use:

• Position the product as close as possible to the cold source, preferably in direct contact with it.
• The basin’s insulation extends the working life of crushed ice, but you should watch the melting of ice during operation and add ice as needed. · The basin can be used even without a cold source, however, not for foodstuffs that require cold storage.
• Place crushed ice/cold bed in the basin as near as possible the serving time.

After use

Emptying the basin

Nova and drop-in units have a drain valve beneath the basin. Water can be emptied by opening this valve.

If the unit has not been connected to the sewer system, it is extremely important to keep the drain valve tap closed at all times except during emptying, particularly when the unit has been installed on a watersensitive floor surface, such as parquet.

Cleaning

In normal use, the appliance does not require any other daily care than sufficient cleaning.

For cleaning the interior and exterior, use neutral or slightly alkaline cleaning agents or wipe the surfaces with a damp cloth. Abrasive materials should not be used.

 Use of a hose for cleaning the appliance is forbidden.

Clean the condenser once a week.The machinery does not normally require any other cleaning. Vacuumclean the condensing unit using a plastic nozzle to avoid damaging the condenser.

 Before vacuum-cleaning the condenser, switch off the appliance at the mains by unplugging the electric cable from the socket.

 Other cleaning procedures except the condenser cleaning should be carried out by an authorized service workshop.

 It is recommended to have the compressor cassette cleaned inside by a service company 1-2 times a year.

Installation

Operating conditions

The appliance is designed for operation at temperatures of +10°C to + 25°C.
The appliance should not be placed close to bain-maries or ovens.

Transport and storage

The appliance should be transported to the installation site in its transport package. Do not remove package until in the immediate vicinity of the installation place. The appliance should be transported in an upright position.

The appliance is made of polished stainless steel and of plastic, so it can become scratched very easily in site conditions. Therefore, the appliance should be delivered to the installation site at a later stage of construction work. It is forbidden to use the appliance as an installation base.

 The appliance should not be stored outdoors, not even in its transport package.

Cold basin and frost plane

 In case the appliance has been stored in a non-heated location so that its temperature and particularly the temperature of the machinery has fallen below 0°C, the appliance should be kept in room temperature until the machinery temperature is at least 10°C. Starting the cold machinery may damage the compressor.

 In case the appliance has been heavily tilted just before the intended start- up, you should wait about 30 minutes before switching the appliance on. Otherwise the oil accumulated in the suction inlets of the compressor may damage the compressor with a hydraulic shock.

Unpacking the appliance

Remove foils protecting the stainless steel and plastic surfaces cautiously to prevent the surfaces from getting scratched.

Installation of Nova units

If the unit is fitted with wheels, it must be installed on a level surface. When the unit is in its correct place, the wheels must be locked to point away from the center of the unit. If the unit is fitted with legs, these can be adjusted so that the unit stands steadily on an uneven surface as well.

If a serving line is composed of several units, they can be linked together from under the tray slides with the help of gray Nova connectors delivered with the unit.

Electrical connections

Connect the appliance to the power supply with an earthed socket. For making the connection, a socket protected with a fuse of max. 16 A has to be provided for each unit.

Start-up
