6.1 Drain the Air Tank from Condensed Water
When using compressed air, water condenses inside an air tank in the Density. This has to be emptied once every two weeks to
maintain the compressed air capacity.
To drain the air tank follow this routine:
1. Turn the machine off and use up all compressed air in the system by shooting with the air gun in the blasting chamber.
2. When the pressure has been removed from the system go to the right side of the Density. At the bottom of the right side,
you find two valves.
3. Put some paper below the opening of the valve closest to Density’s back and open it.
4. Let the water run out onto the paper and then close the valve again.
CAUTION: Always be certain that the system is depressurized before opening the valve.
