Vacuum system SH820G / SR820G SH840G / SR840G
Translation of Originial Operating Instruction, KNF 325562-325564 06/21
CAUTION
In order for the high-performance condenser to recover
solvent from the pumped gas, it must be cooled by
means of a cold water connection or circulating cooler.
DANGER
Excessive pressure, with all of the associated hazards,
can be prevented by means of a bypass line with a pres-
sure relief valve between the pressure side and suction
side of the pump. Further information is available from
KNF Customer Service (contact data: see
www.knf.com).
Risk of bursting of high-performance
condenser
The high-performance condenser is
not pressure-resistant.
à
Make sure that the gas outlet of the
high-performance condenser is not
blocked or restricted.
à
Observe the maximum permissible
operating pressure of the vacuum
system (see 4 Technical data
[} 16]).
Risk of dangerous gas mixtures during
pump operation
Depending on the medium being trans-
ferred, breakage of the media-contact-
ing components can result in a danger-
ous mixture if the medium mixes with
the air in the compressor housing or
the surroundings.
à
Before using a medium, check the
compatibility of the media-con-
tacting components (see 4 Tech-
nical data [} 16]) with the
medium.
