3.7 CLEANING
Remove the PVC film covering the inside and outside of the appliance. Clean the compartment inside using a
sponge damp with lukewarm water.
3.8 WORKING CONDITIONS
Make sure the room in which the appliance is installed meets the following conditions:
•
Ambient temperature between 5°C and 40°C and 40% humidity.
•
Positioning away from sources of heat and in a well ventilated area.
In blast chillers, leave at least 10 cm at the rear in order to properly dissipate the heat produced, in the
cabinets do not place boxes or trays on the technical compartment of the cabinets, and do not set the
cabinets inside niches. Incorrect evacuation of the condenser heat can cause serious malfunctions and
significantly increase the consumption of the appliances.
3.9 COMMISSIONING
Before connecting the appliance to the power mains, make sure that:
•
Voltage and frequency comply with the working conditions featured on the CE plate inside the appliance:
maximum tolerance is ± 10% of the rated value.
•
The power supply circuit meets the regulations in force.
•
The electrical system is fitted with a circuit breaker (r.c.d.).
•
With devices equipped with a humidification system (Levtronic), a filtering system for the supply water of the
humidifier is provided, consisting of a head and a replaceable filter cartridge.
The filter head is provided with a pipe connecting it to the water mains. Once connected to the latter, the
filter should be operated, after being rinsed following the instructions given in the manual supplied with the
filter itself.
Filter life depends on the amount and characteristics of the treated water; in any case, it cannot be longer
than one year. Using a worn filter can result in problems with the supply of water to the humidification
system, causing the latter to fail. Failure to use the filter can cause malfunctions in the humidification system
due to clogging of the valves and/or the sensor that regulates their operation.
•
The supplied filter kit includes two 1.9 m hoses and a Brita filter. The two pipes supplied, on one side have a
3/4 "female connection which will connect to the tap and the humidifier water inlet, on the other side there
is a 3/8" female connection. A 3/4 "male connection is required.
Where a 400V three-phase supply, make sure the fans rotate in the correct direction. If the appliance is
going to be switched off for a length of time, it is best to disconnect its power cord.
Earthing is mandatory. The manufacturer cannot be held responsible for any damage or injury
resulting from failure to earth the appliance or inefficient earthing, incorrect installation,
tampering, poor maintenance and use by unskilled persons, or resulting from failure to comply
with the electrical safety standards in force in the country of use.
For connection to the network, provide a device that ensures complete disconnection in the
conditions of overvoltage category III, in accordance with the installation rules.
When using for the first time, the drain must be filled under the evaporator.
During the cycles it is necessary to plug the condensate drain of the chamber.
Higher temperatures damage the water filtering system.
The unit must be connected to the water network with a temperature below 30°C.
