5.3 START UP
9 Before start up the compressor, check the electrical and air line connections.
9 Check that the compressor’s cooling air inlets and outlets are not closed. Do not cover your
compressor with cloth, nylon etc. Do not operate if covered.
9 Inside electrical panel of your compressor there is a “phase control relay” that continuously checks
the electrical phase. In case the phases are connected in wrong order and if there is unbalance or
interruption in your voltage, the phase control relay will prevent operation of the compressor. In
this case, a signal behind the control panel that indicates the phase error warns you. When the
phases are connected reverse, switch off the energy and switch the position of main cables of the
compressor. In case of interruption or phase unbalance, as this problem is related with the
network contact an electrician or related institution.
9 When the energy and air lines of your compressor are completed, inform your service for
commissioning. Our service will perform the general inspections, start up the compressor and
supply you beneficial information related to your compressor and its maintenance. If you want to
start up the compressor by yourself read this handbook very carefully. Performing an erroneous
process may be hazardous for your compressor facility or the personnel working in this region.
9 Check the oil level. On the oil tank body there is a transparent hose for easily seeing the oil level.
Check the oil level when compressor is stop position. During operation the oil level may vary.
9 If the oil level is missing, complete it. Information related to oil is described in chapter 6.
(MAINTENANCE) , item “ COMPRESSOR FLUID ”.
9 Check the internal components and connections of the compressor. Make sure that during
transportation it has not been damaged.
9 Apply energy to the compressor and check whether the compressor motor is running in correct
direction. The running direction control of compressor: should be made during
commissioning . For this, remove necessary covers.
9 By looking at the airend pulley of the compressor; press the “Start “button and run the compressor
for a short while (1-2 seconds) and stop it by pressing emergency stop button. When looked from
airend pulley side, it should rotate to air end shaft direction. (That is indicated by an arrow on top
of the pulley and embossed at the airend body).
9 If the rotation direction is correct wait for one minute and restart the compressor. Be sure to outlet
valve of compressor is fully open.
9 By closing the valve at the outlet of the air receiver allows the tank to fill.
9
See that the pressure is rising from the compressor control unit screen or from the pressure gauge
over the control panel.
9 See that the pressure reaches the adjusted value and the compressor is getting idle.
9 If the value of the air pressure in tank does not decrease to load level; compressor will
automatically stop at idle after a short time. After waiting a couple of minutes, by opening the tank
outlet valve observe that the compressor is loading at demanded pressure level.
9 After 10-15 minutes, check the operating temperature of your compressor and see that it is normal
80-90 °C (depends on the ambient temperature). Switch off the energy of compressor by stopping
and check internal accessory of compressor by eye. This is very important against the probability
of oil leak or loosening
9 All the functions and reliability of your compressor has been tested after manufacture. The above
mentioned information of commissioning is against the probability of your compressor being
damaged during transportation. If you can not see a failure status after all controls you can start
up the compressor.
