Action
Check that the bolts are fastened.
Check that all connections are correctly
made and that there are no leaks.
CAUTION
Do not tighten the brass couplings for water
and air with excessive force.
Action
Check if there is water in the filter recept-
acle.
Normally the filter receptacle is drained
automatically in case of a fall of air pressure.
If there is no fall of pressure in the air sys-
tem, there is an automatic draining of the
system, when the water level reaches a
certain level.
Drain the air filter receptacle manually by
pressing a small pin at the bottom of the air
filter unit.
Make a check that there is no leakage.
Make a check of the condition of the air filter.
Action
Open the hand operated ball valve for water
inlet.
Open the water return valve on the water in
circuit.
Close the hand operated ball valve for water
outlet.
While the system is under pressure, check
if there are any leaks.
Reset the system.
