Targets of the Manual
This manual represents the principal instrument for the authorised staff caring for the system in its whole. Here are listed all
the professional profiles, involved into the plant management.
USER: The user is the person, body or firm that bought or rented the system and wants to use it for the appropriate ends. He
has the responsibility of the system and of the training of the operating staff.
TECNICOMAR TECHNICIANS: Technical and authorised staff, available from Tecnicomar for system installation and staff
training. He is capable of carry out complex operations on the system and in particular situations.
SYSTEM MANAGER: Authorised and expert operator, trained by Tecnicomar technician on the working and maintenance of
the system. He must be present during every work on the system as the only manager and must overview the observance of the
accident prevention measures. He only must have the keys for access the system and for the activation of the operative modes.
He is, besides, responsible for the system maintenance. He is not authorised to carry out maintenance on the electrical system
or on mechanical parts.
MECHANICAL MAINTENANCE OPERATOR: Qualified technician, with perfect mechanical knowledge of the system,
capable of intervening on mechanical parts and drives to carry out all the maintenance and repairs needed. He is not authorised
to carry out maintenance on the electrical system.
ELECTRICAL MAINTENANCE OPERATOR: Qualified technical staff, capable of working in presence of voltage in cabinet,
electrical boards or connecting box. He is not authorised to carry out maintenance on mechanical parts.
DANGER:
The use of operators and maintenance staff with different qualification other than what is required could
seriously compromise the safety of all the staff involved and of all the people near the system.
DANGER:
All the maintenance and setting operations must be carried out, where not specified, with ECOmar S
STP turned off and power supply off, considering that also the remote management, if provided, must be turned off.
Before executing any maintenance operation it is necessary to switch off the power supply.
If the maintenance operations are well done, the advantage will be to the user since that at restarting of the work he will find
the system under the best conditions. If the operator is authorised and possess the necessary competence and capacity, he can
carry out the control operations and maintenance following the instructions reported in this manual. The complex maintenance
operations must be handled by qualified staff and not by the operator that is still responsible of the maintaining in good state
of the system. The validity and qualification of the maintenance operations are determinant factors for the system efficiency.
For that reason the maintenance must be adequate to avoid damage of the most stressed organs and to maintain a high system
reliability.

Safety Instructions and Prevention
7.5.1
Generalities
The safety of the operator represents one of the principal issue for a manufacturer. When producing a system, the manufacturer
tries to expect all the possible danger situation that can verify to adopt all the appropriate safety preventions. There are anyway
accidents caused by improper use of the system and equipment. It is good to remember that caution is necessary to prevent
accidents during the system working.
DANGER:
It is forbidden to remove panels and protections of the module and of its loose parts,
especially during the working. Same for electrical equipment, that can also be a danger even when placed
in not operative mode for having parts on permanent voltage. Remember that to operate with partially
removed boarding and protections means to be in contact with hazardous voltages, moving parts or too
much hot parts that could provoking accidents even lethal. Nevertheless, in certain cases, for inspections
and/or maintenance activities it can be necessary to turn on the sewage treatment plant leaving open
some board or protections. These working conditions are only allowed to qualified and authorised staff,
aware of the possible danger, which must adopt all the possible precautions to avoid injuries.
The electrical board and all the electrical equipment are realized according to the applicable norms. The electrical safety is
assured by all the necessary equipment and precautions. This not mean that it cannot be source of danger and lethal accidents.
It is recommended to not remove or open boards unless upon possession of the necessary experience and knowledge in
electrical field and aware of the potential danger. The protection against electrical shock, caused by open contacts is only
assured with closed boards. It is not allowed to turn on the system without verification of the closure of the electrical boards.
WARNING:
The use of ECOmar S STP causes the overheating of some parts of the system. So it is good that eventual
controls are done with system turned off and after cooling.
DANGER:
The light of ultraviolet lamps may cause severe burning to unprotected skin and eyes. Avoid connecting
the appliance to the electricity supply before fitting the UV lamp into the socket and fitting the protective covers.
7.5.2
Noise
Before to approach the plant or any of its loosed parts it is necessary to equip protection instruments to protect the hearing
(headphones, plugs, etc.).
