Pressure vessel
Pressure tested at: 4-25 liter:
40-50 liter:
Directions for use
Application Receiver for compressed air.
Receiver specifications See name plate.
Installation Tubes, etc. must be made of
suitable materials.
Placement Observe the working temperature
of the receiver.
Ensure that sufficient room for
inspection/maintenance is
available in a horizontal position.
The receiver must be kept in a
horizontal position.
Corrosion protection The surface treatment must be
maintained as required.
Internal inspection at least every
5 years.
Drain moisture at least once a week.
Alternation/repair No welding must be made on
pressurized parts.
Safety valve Ensures that PS will not be exceeded.
Never adjust to a higher pressure
than PS.
The capacity of the valve must be
calculated in accordance
with the volume of air supplied by
the compressor.
(PS = Maximum working pressure
of the receiver)

c) Failure in non-return valve which is creating a flow
restriction.
d) Check the piston gaskets. Replace, if necessary.
e) Desiccant has been contaminated and/or filter elements
have been clogged (this only applies to model „D“).
Replace. See "Adsorption Dryer Manual".
4. Loud noise from compressor:
a) Dirt or failure in non-return valve. Clean or replace.
b) Defective fan (this only applies to model „P“).
5. Compressor gets very hot:
a) Leaks. See point 3b.
b) Intake filter clogged. See point 3a.
c) Too high ambient temperature. Do not enclose unit in a
cupboard unless adequately ventilated. The compressor
should be placed in coolest possible place.
d) The cooling fan at the top of the cabinet does not run
(this only applies to model „P“). Check pipes and fuses.
e) Overloaded. Ensure compressor is correct model for
work load.
6. Compressor starts when no air is being tapped:
a) Leaks. See point 3b.
7. Compressor starts and stops more frequently than
usually:
a) Large amount of condensate in air receiver (on units
without dryer). On units with dryer condensate may be
found if dryer is defective (this only applies to model
„D“).
b) Leaks. See point 3b.
8. Compressor does not switch on against pressure or
does not switch off at max. pressure:
a) Defective pressure switch. Replace.
