Prior to the initial startup, the supply lines
from the site-supplied supply units must be
connected to the tank cleaning device.
Caution
In order to avoid damage to the com-
pressed air drive by condensation wear
and lack of lubrication, install a mainte-
nance unit into the compressed air supply.
This maintenance unit must be laid out as
follows:
– Air throughput of 60 m 3 /h (with standard
conditions)
– Pressures of up to 0.6 MPa (for safety
reasons)
– The hose line between the mainte-
nance units and the tank cleaning de-
vice must not be longer than 3 m.
The maintenance unit consists of:
– Filter
– Water separator
– Pressure regulator with manometer
– Proportional oiler
 Fill the proportional oiler with a suitable
lubricant. Oil type - see operating in-
structions of the compressed air motor.
 Set the oiler to 50 mm 3 oil per standard
cubic meter (mm 3 /m 3 ) compressed air,
see operating instructions of the com-
pressed air motor.
– Hose size for supply air as per DIN 10
 Blow the hose clean and connect it to
the compressed air connections (P2).
The exhaust air of the compressed air mo-
tors exits at the connections "1" and "EXH".
Here, you can connect mufflers or exhaust
hoses.
Note: A reflux of the exhaust air causes an
unsafe run of the compressed air motor.
Therefore, you must use large enough muf-
flers or hoses.
