These Operating Instructions
 contain instructions bearing on transport and
handling, installation, commissioning,
operation, shut−down, storage, servicing and
disposal,
 must be completely read and understood by
all operating and servicing personnel before
beginning to work,
 must be strictly observed,
 must be available at the site of operation in a
complete and perfectly legible condition.
Operating and servicing personnel
 These persons must be trained and
authorized for the work to be carried out.
 Work on electrical installations may be carried
out by trained and authorized electricians
only.
G-BH1e series side channel blowers in
conjunction with frequency inverters
 are pump−motor units for generating vacuum
or gauge pressure.
 are used to extract, pump and compress the
following gases:
– Air,
– Non−flammable, non−aggressive,
non−toxic and non−explosive gases or
gas−air mixtures.
– With differing gases/gas−air mixtures,
inquire with the manufacturer.
 are intended for industrial applications.
 are designed for continuous operation:
– With increased switch−on frequency (at
equal intervals of approx. 5 times per hour)
or increased gas entry temperature and
ambient temperature, the limit
overtemperature of the winding and the
bearings can be exceeded.
– Consultation with the manufacturer is
required for operating conditions of this
kind.
 are equipped with a three−phase drive motor
with mounted frequency inverter.
 are available in the following models:
–
single−impeller (single−stage)
– two−impeller (two−stage) for increased
pressure difference
– two−impeller (double−flow) for increased
delivery volume
During operation the limit values listed under
"Technical data" must always be complied with.
