6 ELECTRICAL INSTALLATION

6.1 General specifications

All electrical connections to the unit must be carried out in compliance with laws and regulations in force.

All installation, management and maintenance activities must be carried out by qualified personnel.

Refer to the specific wiring diagram for the unit you have bougth. Should the wiring diagram not be on the unit or

should it have been lost, please contact your manufacturer representative, who will send you a copy.

In case of discrepance between wiring diagram and electrical panel/cables, please contact the manufacturer

representative.

Only use copper conductors. Failure to use copper conductors could result in overheating or corrosion at connection points

and could damage the unit.

To avoid interference, all control wires must be connected separately from the power cables. Use different electrical

passage ducts for this purpose.

Particular care must be taken when realizing wire connections to the switchbox; if not properly sealed, cable entries may

allow ingress of water into the switchbox which may cause damage to the equipment inside.

Before any installation and connection works, the unit must be switched off and secured.

This product complies with EMC standards for industrial environments. Therefore it is not intended for use in residential

areas, e.g. installations where the product is connected to a low voltage public distribution system. Should this product

need to be connected to a low voltage public distribution system, specific additional measures will have to be taken to

avoid interference with other sensitive equipment.

7 OPERATION

7.1 Operator’s responsibilities

It is essential that the operator is appropriately trained and becomes familiar with the system before operating the unit. In

addition to reading this manual, the operator must study the microprocessor operating manual and the wiring diagram in

order to understand start-up sequence, operation, shutdown sequence and operation of all the safety devices.

During the unit’s initial start-up phase, a technician authorized by the manufacturer is available to answer any questions

and to give instructions as to the correct operating procedures.

The operator must keep a record of operating data for every installed unit. Another record should also be kept of all the

periodical maintenance and servicing activities.

If the operator notes abnormal or unusual operating conditions, he is advised to consult the technical service authorized

by the manufacturer.

8 MAINTENANCE

8.1 Routine maintenance

This chiller must be maintained by qualified technicians. Before beginning any work on the system the personnel

shall assure that all security precautions have been taken.

Neglecting unit maintenance in these environments, could degrade all parts of the units (coils, compressors, frames, pipes,

etc..) with negative effect on performances and functionality.
