3.4 Electrical check
Important!
Al though all electrical instructions addressed to the reader directly, the actual inspection,
wiring, installation, maintenance, repair etc. must be carried out by licensed and certified
electricians.
Make electrical connections to the compressor in accordance with the wiring diagrams and in full compliance
with all applicable Federal, State and Local standards, codes and regulations, including those dealing with the
grounding requirements. A few electrical checks should be made to insure that the first start up will be trouble
free. Make the following checks before attempting any start up
1. Check the line voltage. Verify that the compressor motor corresponds to mains specifications.
2. Check the starter and overload for conformity with the motor power and current data.
3. Check all electrical connections for tightness, including those in the electrical panel of the compressor.
4. At start up, check the direction of rotation to insure flywheel rotating in the direction of the arrow on
it. Although a few minutes of operation in the wrong direction of rotation will not damage the
compressor, but running it this way in normal operation will create serious damage as the cooling air
flow will be reversed, preventing the compressor cylinders to be cooled during operation.
3.5 Wiring
It is important to select the right size wire and fuses. Install an isolation switch on the wall where the mains line is
carried to, with magnetic protection and a capacity three times greater than the motor full load current. Use the same
size wire between this unit and the compressor electrical panel.
3.6 Sheaves and V-belt alignment check
Check the V-belt tension. Proper tension should be adjusted to give about 13 mm ( ½ ”) deflection with a 1 kg (2
pnds) weight applied at the center of each belt. Check the condition of the belts periodically (see the maintenance
table for details.
3.7 Storage
If compressor will not be working for a long time for any reason and will be stored during this time, it is
suggested to do the following steps before putting it out of reach in order to keep it in good condition:
1. Start the compressor and run it for app. 15 minutes.
2. Check if there is any leak on the fittings, hoses, tubes, filters and valves.
3. Open the filling valves and run it for app. 2 minutes at the min. pressure (the pressure which the priority
valve is set at).
4. Open the drain valves and release the pressure inside the compressor.
5. After the unit is completely depressurised stop the compressor. Close the filling valves and drain.
6. Take out the refillable cartridge inside the purifier housing.
7. Remove the intake filter and disconnect all other connections on the valve heads.
8. Restart the compressor as soon as it cools down. Spray some compressor oil to the valve intakes and
run the compressor for 2-3 minutes in this position.
9. Stop the unit before it gets too warm.
10.
Connect the lines to the valve heads which are previously disconnected.
11. Close all the valves and put a cap onto the intake port against the dust and fumes may enter.
