Safety valves
Every pressure-stage is equipped with its own safety valve. They protect
the unit from over-pressure / load.
The valves are adjusted to:
st
1
Stage: 15 bar
nd
2
Stage: 72 bar
rd
3
Stage: final pressure
If a safety valve blows it indicates problems with either inlet or outlet valve
of the next stage.
NOTE: A faulty safety valve should always be replaced!
Removing the compressor cover
The compressor cover is held in place by three allen screws (M8). One is
placed on top of it, two are mounted to the frame. In order to reach them,
tilt the unit and loose screws by 6 mm allen key.
Pressure maintaining valve
A pressure maintaining valve is fitted next to the water separator / filter
housing. It is adjusted to provide a pressure of at least 160 bar to the
filling hose, optimising the effectiveness of the filter to ensure the best
possible air quality.
Changing the mole carbon cartridge
The mole carbon cartridge lasts for about 20 (LW 160 E) / 17 hours (LW
190 B) at an average humidity and at 25 degree centigrate. At 30 degree
centigrate plus and high humidity, its life is reduced to 11 (10) hours. The
cartridges are packed airtight.We recommend that they should be opened
just before they are fitted to the compressor, as they could be saturated
with moisture just being exposed to high humidity. To change the filter
cartridge stop the compressor and release all the pressure by opening the
drain and filling valves. Once the unit is free of pressure the filter housing
cap can be unscrewed using the filter tool delivered with the compressor.
