Safety
WARNING
Improper handling of the system can result
in serious or fatal injuries!
Only reliable trained specialised staff may
carry out work on and with the system (transpor-
tation, installation, setting up, taking out of op-
eration, maintenance, disposal).
WARNING
Working on the system involves a risk of
injury, e.g. through cutting / shearing,
squashing and burning!
• First get personal protection gear (gloves,
safety shoes).
• And only then work on the system!
WARNING
Hair and clothing can be drawn into the sys-
tem or caught or wound in by moving parts!
• Do not wear any large or loose items of cloth-
ing!
• If you have long, loose hair, wear a hair net!
DANGER
Electrical hazard!
Before beginning any work on the system:
• De-energize it.
• Protect it from being switched on again.
• Make sure that it is de-energized.
• Earth it and bypass it.
• Cover or block off adjoining parts which are
still live.
DANGER
Electrical hazard!
Work on electrical equipment may only be car-
ried out by qualified and authorized electricians!
WARNING
Hazard presented by negative pressure!
• First ventilate the feed lines (relieve pres-
sure).
• And only then work on the system!
WARNING
Hazard presented by negative pressure!
• First check that all pipe connections, feed
lines and containers are firm, sealed and
have a tight fit.
• Then check the fasteners have a tight fit.
• And only then start up the system!
WARNING
Negative pressure at the suction intake!
Only operate with the feed line connected to the
suction intake!
• Do not approach the suction intake if you
have long, loose hair or are wearing large,
loose clothing,
• Do not peer into the suction intake or bring
your eye in front of the opening of the suction
intake.
WARNING
Hazard presented by moving parts!
Do not put your hand into the unit through any
opened suction or pressure joints!
Do not put objects into any of the openings in
the unit!
1.2.1 Other risks
DANGER
Electrical hazard!
The system is still live for a period of at least 3
minutes following disconnection of the power
supply.
• Before carrying out any work on the system
make sure that it is de-energized.

Correct Use Of The Equipment
2 Correct Use Of The Equipment
This instruction manual
• applies for vacuum pump systems in the 2SH
series, type 2SH7 530.
• is complemented by the instruction manual for
the G_400e Liquid-Ring Vacuum Pump.
• contains instructions on transport, installation,
commissioning, operation, decommissioning,
storage, maintenance and disposal of the
2SH.
• must have been read and properly understood
2SH by operating and maintenance staff be-
fore beginning any work.
• must be complied with.
• must be available at the 2SH location.
The operating and maintenance staff for the 2SH
must be trained in the work to be carried out and
authorised to do so.
Work on electrical equipment must only be car-
ried out by a qualified electrician.
The 2SH
• is a system for the creation of a vacuum.
• consists of:
-
a housing with wheels (pos. 8, page 3)
-
a liquid ring vacuum pumps in the G_400e
series, type 2BH7 (pos.
10, page 3) (re-
ferred to below as the “unit“).
-
a vacuum shut-off valve (pos. 20, page 4).
-
an E-modulus with frequency converter
(pos.
12, page 4)
-
an in-line filter (pos. 17, page 4)
-
a pressure gauge (pos. 4, page 3)
-
and status indicator lights (pos. 1-3, pa-
ge
3).
• is used to extract, transport and condense the
following gases / vapours:
-
all dry and damp gases which are not ex-
plosive, combustible, aggressive or poi-
sonous,
-
preferably air or air-vapour mixtures.
-
for gases / vapours other than these,
please check with the service department.
• which, during operation, releases gases into
the environment with the following character-
istics:
-
outlet temperature max. 85°C,
-
outlet pressure ≈ ambient pressure,
-
clean and free of dust.
• is designed for industrial plant.
• is designed for continuous operation.
-
if it is switched on very frequently (at equal
intervals, about 5 times an hour) or there
are excessive gas inlet and ambient tem-
peratures, the tolerable coil and storage
temperatures could be exceeded.
-
consultation with the manufacturer is es-
sential for such operational conditions.
When operating the 2SH the limiting values listed
in chapter
3 Technical Data, page 8 ff are to be
complied with.
Foreseeable Misuse
The following are forbidden:
• use of the 2SH in non-industrial plant, unless
the necessary precautions and protective
measures have been taken at the plant, e.g.
protection against contact by children's' fin-
gers.
• use in areas in which explosive gases may
become present.
• the extraction, transport and condensing
of explosive, combustible, aggressive or poi-
sonous media.
• operation of the 2SH at any values other than
those given in chapter
3 Technical Data, page
8 ff.
For reasons of safety2SH it is forbidden to make
any changes to the .
The unit must not be either dismantled or disas-
sembled!
The Operator is allowed to carry out maintenance
and repair work to the extent described in this
instruction manual.
Maintenance and repair work which goes beyond
this to should only be carried out by companies
which have been authorised by the manufacturer
(ask the service department for details).
