SAFETY REGULATIONS GENERAL WARNINGS • The rotating compressors are destined for arduous and continuous industrial use. They are particularly adapt for application in industries where a large consumption of air is requested for long periods of time. • The compressor must be used exclusively as indicated in this manual, which must be kept carefully in an easily accessible place known to everyone, as it must remain with the machine for its entire duration.

SAFETY REGULATIONS TO DO: Make sure that mains voltage corresponds to the voltage indicated on CE plate and that cable of suitable cross-section are used for electric connections. Always check oil level before starting the compressor. Be familiar with emergency stop control and all other controls. Unplug the connector before any maintenance work, so to avoid accidental start.

START-UP AND OPERATION 1 - CHECKS TO BE CARRIED OUT PRIOR TO START-UP N.B.: The customer is responsible for installing the machine and making the required electrical and air connections. Initial system start-up must be carried out by skilled personnel who will make the various checks required and follow the respective instructions.

START-UP AND OPERATION WORKING CYCLE • At the end of the starting cycle, the compressor reaches maximum operating speed and starts to compress air in the tank (4). • At a value of - 0.5 bar operating pressure, the compressor begins to modulate the motor rotation frequency (max. 100%, min. 50%) in such a way as to maintain constant the selected pressure depending on the flow of air.

START-UP AND OPERATION 2 - CONTROL PANEL The compressor is fitted with a “control panel” for setting up and monitoring machine operation. The operating parameters were entered by the Manufacturer during “testing”. The parameters were tested for several hours in the various operating conditions. The features offered by this electronic control system includes: •...

START-UP AND OPERATION Input configuration: Sub-menu allowing you to configure the logic of all the control unit inputs and associate a function of your choice to input CN2-1, among: “oil filter, “air filter” and “air pressure switch”. By setting the configuration equal to 1, the input logic will be denied.

START-UP AND OPERATION Alarm! Air filter: When an air filter anomaly occurs, the alarm BLOCKS the compressor. Alarm! Oil separator filter: When an oil separator filter anomaly occurs, the alarm BLOCKS the compressor. Alarm! Inverter fault: When an inverter anomaly occurs, the alarm BLOCKS the compressor. To re-start the compressor, you need to reset the inverter.

MAINTENANCE • Correct maintenance is crucial to achieve maximum efficiency of your compressor, and to lengthen its operating life. • It is also important to comply with the maintenance intervals recommended, but it must be remembered that such intervals are suggested by the manufacturer in the event that the environmental conditions of use of the compressor are optimal (see “Installation”...

MAINTENANCE DRAIN CONDENSATE (Fig. 6) The oil/air mixture cooling is set at a higher temperature with respect to the dew point of the air (under standard operating conditions of the compressor). However, the condensate in the oil cannot be fully removed. Blow off compressed air through cock B and then close it as soon as oil begins to flow out instead of water.

MAINTENANCE REPLACING THE OIL When the compressor is hot - above 70 °C, replace the oil. Alarm signal • Remove the front panel • Connect the drain hose provided to cock B located at the base of the separator tank. •...
MAINTENANCE THERMOSTATIC VALVE REVISION (Fig. 12) Replace the cylinder with the thermostatic element, highlighted by letter H. CLEAN AIR PREFILTER (Fig. 13) • Remove prefilters A-B from their seat. • Wash with soapy water solution, dry them completely before restarting the machine. CONDENSATE DRAINAGE SOLENOID VALVE FILTER CLEANING (Fig.14) • Unscrew the filter and remove it from the compartment on tap B.
TROUBLESHOOTING Problem Cause Remedy Motor stopped (thermal relay Voltage too low. Check voltage, press Reset and then restart. operation signal) Overtemperature. Check motor absorption and relay setting. In case of regular absorption press Reset and restart. Oil consumption high Drainage faulty. Check oil drain hose and check valve.
