Only properly qualified installationengineers and highly qualified technicians, fully trained for theproduct, are authorised to install and start-up the equipmentsafely.

6 During all servicing operations all instructions andrecommendations which appear in the installation and serviceinstructions for the product, as well as on tags and labels fixedto the equipment and components and accompanying partssupplied separately, must be read, understood and Apply all standard safety codes and Wear safety glasses and Use the proper tools to move heavy objects. Move unitscarefully and set them down - Avoid electrocutionOnly personnel qualified in accordance with IEC (InternationalElectrotechnical Commission) recommendations may bepermitted access to electrical components.

7 It is particularlyrecommended that all sources of electricity to the unit be shutoff before any work is begun. Shut off the main power supplyat the main circuit breaker or :This equipment uses and emits electromagnetic signals. If it isnot installed and used in complete accordance with theinstructions given here it may cause radio interference. Testshave shown that the equipment conforms to all applicablecodes with respect to electromagnetic OF ELECTROCUTION:Even when the main circuit breaker or isolator is switchedoff, certain circuits may still be energised, since they may beconnected to a separate power OF BURNS:Electrical currents cause components to get hot eithertemporarily or permanently.

PRO-DIALOG controls compres-sor start-up needed to maintain the desired chilled watertemperature. It controls the operation of the fan to maintain thecorrect condensing pressure in each circuit. Safety devices areconstantly monitored by PRO-DIALOG to ensure their safeoperation. PRO-DIALOG also gives access to a Quick Test pro-gram covering all inputs and PRO-DIALOG Plus controls can work in accordance withthree independent modes:- Local mode: the machine is controlled by commands fromthe user Remote mode: the machine is controlled by remote contacts(volt-free contacts).

9 - CCN mode: the machine is controlled by commands fromthe Carrier Comfort Network (CCN). In this case, a datacommunication cable is used to connect the unit to the CCNcommunication operating mode must be chosen with the Start/Stop buttondescribed in section When the PRO-DIALOG Plussystem operates autonomously (Local or Remote mode) itretains all of its own Control capabilities but does not offer anyof the features of the CCN - Abbreviations usedIn this manual, the refrigeration circuits are called circuit A andcircuit B.
