Insert the plug into the electrical outlet and start up the compressor by pushing the "I" switch on the control panel (fig.4) At start-
up, check if the flywheel-fan rotation direction is correct - the cooling air must be discharged from the rear of the
soundproofing cabin. The electric system was inspected by the manufacturer at the time of the general inspection and therefore
guaranteed as petfect and operating. Any damage caused by improper power connections to the line automatically excludes the
guarantee of electrical parts. To avoid improper connections, consulta specialized technician.
OPERATION
It is extremely important that the machine functions with all the panels well closed. The operation of the compressor is completely
automatic, controlled by the pressure switch which stops it when pressare reaches the set maximum level, and allows g-te start up
again when it goes down to the set minimum value.
Only for SSA models: The compressor is equipped with asupplementary fan controlled by a thermal probe. When the temperature
reaches excessive levels inside the cabin the supplementaryfan starts and remains in operation unti1 the temperature normalizes
inside.
THERMAL PROTECTION (only SSA mod.)
The thermal relay is set during the final-test in the factory. If the contact is disconnected (causing the red indicator light on the
control panel to go light up), reset it by opening the panel of the electrical box (fig. 4), and pressing the indicated push-button (fig.
6). If the contact disconnects again, do not continue resetting and do not change the relay setting, but find out what prevented the
electric motor from starting, and, if necessary, contact your nearest service centre.
THERMAL PROTECTION (only SCS mod.)
The thermal relay is set during the final-test in the factory. If the contact is disconnected reset it by press the RESET button (fig.4)
on the pressure switch. If the contact disconnects again, do not continue resetting and do not change the relay setting, but find out
what prevented the electric motor from starting, and, if necessary, contact your nearest service centre.
MAINTENANCE
CAUTION
Before any intervention inside the sound-deadening cabin, make sure of the following:
-The general line switch is in the "0" position.
-The green indicator light on the control panel must be OFF.
-The compressor is cut out from the compressed air system.
-The compressor and the internal pneumatic circuit are unloaded from any pressure.
PANEL REMOVAL
Lift the upper cover (fig. 5) and unfasten the lock screws to remove the side panels (fig. 7).
OIL TOPPING UP-OIL CHANGE
Check the oil leve1 of the pumping element (fig. 8) every 100 hours of operation. If necessary, top up with oil "SYNTHESIS 5W50".
Replace the oil of the pumping element completely every 500 homs of operation. Remove.the casing cap to drain oil. Fit the cap
back and put in bit unti1 it reaches the'level (fig. 9). With other types òf oil for compressors, replace every 200 hours of operation.
Do not abandon used oil in the environment.
CLEANING AND CHANGING FILTER CARTRIDGE
Every month clean the intake filter by blowing compressid air onto the cartridge (fig. 10). It is recommended to replace the air filter
cartridge at least once a year if the compressor-operates in a clean evironment, and more frequently if the-location of the
compressor is dusty.
WATER DRAINAGE
With drier:
The condensation water is automatically drained whenever the compressor stops. The water is drained via a tube at the rear of the
unit. During installation, make sure that that the water is drained into a storage container. Periodically check if the discharge
automatism operates efficiently. Do not abandon in the environment condensate produced by the oil-lubricated compressor
because it contains oil.
Without drier:
The compressor produces condensation water which accumulates in the tank. Condensate must be discharged from the tank at
least once a week. Do this by opening the drain tap under the tank. Be wary of any compressed air inside the cylinder - the water
could come out with great force. Recommended pressure : 1-2 bar max.
PRESSURE SWITCH (SSA mod.)
For the pressure switch, drain the condensate at least once a week; when doing so, make sure the machine is stopped and no
longer electrically powered. Get hold of a container to collect the condensate. Open the left hatch of the machine with the dedicated
key, slowly open the cock (fig. 12), leave it to blow until you no longer see any condensate coming out of the cock, making sure to
drain the condensate into the dedicated container.
PERFORMING MINOR REPAIRS
AIR LEAKS FROM THE HEAD DISCHARGE SOLENOID-VALVE (SSA mod.)
This problem is due to an improper sealing of the check valve. To repair (fig. 11). Cut out the compressor from the power line and
the compressed air system. The internal pneumatic circuit and the compressor must be unloaded from any pressure.
-Ufifasten the hexagonal head of the valve (A).
