Electrical Cabinet; Residual Risks; Access To Internal Components - Ferroli OMNIA S 3.2 Manual De Instalación, Uso Y Mantenimiento

Do not touch the appliance with bare feet or with wet or moist parts of the body.
The checks described must be performed at least once a year by qualified personnel.

Electrical cabinet

Carry out a thorough visual inspection of the components of the electrical panel to check for damaged or incorrectly connected components or cables (check the
tightness of the terminal screws).

Residual Risks

The machines has been designed with a view to reducing the risks to persons and the environment in which it is installed, to the minimum. To eliminate residual risks,
it is therefore advisable to become as familiar as possible with the machine in order to avoid accidents that could cause injuries to persons and/or damage to property.
a. Access to the unit
Only qualified persons who are familiar with this type of machine and who are equipped with the necessary safety protections (footwear, gloves, helmet, etc.) may
be allowed to access the machine. Moreover, in order to operate, these persons must have been authorized by the owner of the machine and be recognized by the
actual Manufacturer.
b. Elements of risk
The machine has been designed and built so as not to create any condition of risk. However, residual risks are impossible to eliminate during the designing phase and
are therefore listed in the following table along with the instructions about how to neutralize them.

General Rules for Maintanance
The maintenance is extremely important for the functioning of the system and the regular working of the unit over time.
In accordance with the European Regulation EC 303/2008 , it should be noted that companies and engineers in maintenance , repair, leak testing and recovery /
recycle refrigerant gases should be CERTIFIED in accordance with local regulations.
Maintenance must be performed in compliance with the safety rules and tips given in the manual supplied with the unit.
Routine maintenance helps maintain unit efficiency, reduce the rate of deterioration which each device is subject in time and gather information and data to understand
the efficiency of the unit and prevent failures.
For extraordinary maintenance or in case you need service , contact only to a specialized service center approved by the manufacturer and use original spare parts.
In accordance with the European Regulation EC 1516/2007 it is necessary to prepare a "equipment record".
Provide anyway a databook (not supplied) that allows you to keep track of interventions made on the unit; in this way it will be easier to properly program the various
interventions and will facilitate a possible troubleshooting.
Bring on the databook : date, type of intervention made, description of the intervention , measurements , reported anomalies , alarms recorded in the alarm history ,
etc. ...
