a) Pressure connection at (Fig. 2/B).
NOTICE
Material damage resulting from the forces and
torques of the pipes on the unit being too high.
Only screw pipes in by hand.
The compressor volume fl ow is reduced if the
pressure pipe is too narrow and/or too long.
b) Check to ensure the pressure line is connected
correctly.
NOTICE
Length of the connection pipes
With connection pipes that have the same pipe
cross section as the machine connection and are
more than 3m long, a non-return valve especially
for the purpose must be installed in order to avoid
reverse operation when the machine has stopped.
As a protection against overload a safety valve
(Fig. 2/D) is installed as standard.
NOTICE
Do not operate without the standard safety
valve
If the permissible fi nal compression pressure is
exceeded (see data plate) the machine may be
damaged.
The safety valve is a part that is subject to
wear and must be replaced after 10,000 hours
or after no more than 2 years
