Switch all circuit breakers to the “on” position.
Fan should be checked for the correct rotation. (Please note that there is an arrow located at the side part of the fan-shroud
for direction indication). Reverse two phases R-S-T on the terminal board in case of incorrect rotation.
NOTE: for units without fan please verify the correct rotation on the pump motor.
At this time the Chiller should operate automatically according to the controllers “set point values”. If necessary, set controller
according to customers temperature requirements. (Please refer to the manual of the thermostat delivered with the unit).
NOTE: The unit works correctly only if the cover panels are mounted on the unit, so if for some
reason during the installation of the Chiller they have been removed, please replace them
before switching on the unit.
After installation, the REFRIGERATOR does not need intervention by the Qualified Operator.
Every calibration operation on thermostats, pressure switch and whatever component of the refrigerating circuit, the personnel
of the Technical Servicing or the Refrigerator Technician only is competent.
