On models of 300 bar rated filling pressure
do not attach bottles unless rated for this
pressure (note pressure stamped on tank
neck).
Abb. 15 Connecting air bottle
- Air bottles with international filling connector can be
connected with filling adaptor (PN 79375) to the German
filling connector (see Abb. 16).
Abb. 16 International filling connector
The international connector is not per
mitted in the Federal Republic of Germany.
In other countries it is allowed only for
pressures up to 200 bar (2,850 psi).
Filling the bottles
- Open filling valve (1, Abb. 17).
- Open bottle valve (2) - bottle will be filled. Drain conden
sate regularly during filling. On units with automatic con
densate drain check that condensate is drained regularly.
The filling procedure should not be inter
rupted for more than 10 minutes to avoid
increased CO

3.6. CHANGE-OVER DEVICE PN 300/PN 200
(Abb. 19) This device allows bottle filling to 200 bar
(3,200 psig) with a 300 bar (4,700 psig) rated unit. Safety
valve (1) and filling device PN 200 bar are connected by open
ing change-over valve (2) and the connected bottles can be
filled with a 200 bar pressure, as described in ”Filling the
bottles”.
Depressurize unit before opening valve (2)
