The A/C units and the condensers are supplied with earth terminals and these must be correctly earthed in order to avoid
possible accidents.
Check the electrical wiring diagrams for correct wiring between indoor and outdoor units.
The contractor installing the equipment must verify that the supply power corresponds to that which is indicated on the
identification plate of the A/C unit as well as on the electrical diagrams supplied.
The manufacturer is not responsible for any damages of any sort if the above indications have not been correctly
followed.
INSTALLATION CHILLED WATER UNITS
Air conditioning units that run on chilled water and / or have hot water coils must be connected to a respective water supply
(hot and chilled water) as indicated in the diagrams that are supplied with each unit.
Each single circuit must have the possibility of being isolated and so shut-off valves should be installed in the lowest points of
the circuit for general maintenance operations.
All the piping for the supply and return of the water should be well insulated in order to avoid heat dispersion and the
formation of condensate.
Ensure that there are no leakages in the circuit, fill the installation and remove any air that may have remained in the various
circuits by acting on the relief valves that are normally found on the collector of the coil or any other high point in the circuit.
If the unit is supplied with a motorised valve, check that the servomotor operates correctly and the the opening of the valve is
synchronised with the demand for cooling.
The condensate discharge and the connections to the humidifier, as well as electrical connections, have all been described in
the previous chapters.
