nance and repair.
3. Before dismantling any part that has been
pressurized, disconnect the pressure
sources and depressurize the system com-
pletely. Shut off all valves and isolate the
dryer.

modified in any way.
6. Never leave tools, loose parts or cleaning
rags in or on the air dryer.

check the setting of the control and safety
devices as well as the pressure and the tem-
perature of the compressed air circuit.

ant, the dryer should be regularly checked
to be leak free by qualified refrigerant
engineer. Refer to section “Environmental
protection” of this manual.
3. Every six months - check the correct opera-
tion of the condenser drain trap. Replace
timer or solenoid valve in case of clogging or
malfunctioning.

strainer or the electronic sensor by undoing
the access screw and rinsing the filter with
tap water to remove the trapped dirt from the
