11.
Check the possible leaks in piping. If there is any leak stop the compressor and let it cool down.
12.
At the end of 10 minutes running the compressor free, close the purifier drain valve allowing the
pressure to rise. Check the last stage safety valve if operating proper or not. The safety valve must
open and leak at the pressure stated on it. If the safety valve does not open, stop the compressor
without waiting for the pressure to rise up.
13.
Fill in the commissioning report and technical data forms. Return a copy to ALKIN for tracking
record.

To fill cylinders, please read Cylinder Filling Instructions.
1.11.2 Oil Recommendation
The oil level should be checked before each start up. Top up to the overfill point when required 550 ml of oil
should be loaded during each replacement.
RECOMMENDED OILS

Do not use another type of oil without prior written approval of the compressor manufacturer.
Do not mix different brand and type of oils.
If you will change the oil you use with another approved brand of oil, refill with the new oil after you
make sure that you drain the old oil completely in the crankcase.
Refill the oil every 6 months unless you reach the replacement time of the oil stated in the
Maintenance Table.
1.11.3 Extremely Cold Ambient Temperatures
Operating conditions different than stated conditions must be reported to the compressor manufacturer to
make the necessary changes to adopt the compressor to the current conditions. For instance if the
compressor needs to work in an extremely cold ambient temperature below freezing temperatures a crankcase
heater can be attached to the crankcase of the compressor to prevent the negative effect of the cold ambient
temperatures.
1.11.4 Motor Lubrication
Electric motors on ALKIN W31 Series compressors are supplied with greased and sealed bearings. They do not no
need further maintenance.
1.11.5 Adjustments
Pressure Switch Adjustment (
For Auto Drain Models)
When adjusting pressure switch, verify compressor is operating and make
adjustments according to the final outlet pressure.
1.
Adjustment is done by rotating the Red Adjustment Screw.
2.
You can adjust PH1 pressure switch to the required upper pressure
(working pressure) by turning the screw on the pressure switch clockwise or anti-
clockwise.
Turn the screw clockwise to increase the upper pressure, anti-clockwise
to lower.
3.
Standard Pressure Switches used on ALKIN have standard differential of
10% of working pressure.
For example, a pressure switch set at 200 bar will work between 180 and
200 bar.
