Working in a safety-conscious manner
Work on running or energised vacuum pumps/compressors can lead to seri-
ous injuries due to body parts being drawn in or crushed or death due to
electric shock.
Work on the G-BH2 at a standstill only and in a de-energized condition.
1. Disconnect.
2. Secure it to prevent it from being switched back on.
3. Make sure that it is de-energised.
4. Earth it and short-circuit it.
5. Cover or block off adjacent parts which are still supplied with voltage.
During operation and after decommissioning, contact with hot surfaces can
lead to burns.
On the G-BH2, temperatures during operation can reach 160Ԩ[320°F].
1. Do not touch hot surfaces during operation.
2. Keep hot surfaces clear of highly inflammable materials.
3. Allow the G-BH2 to cool after shutting it down.

Function principle
The side-channel compressor consists of a drive (motor) and a compressor part in
which an impeller rotates contact-free in the side-channel.
Side-channel compressors can be used as a vacuum pump or are used as the
compressor (observe Correct use of the equipment [➙7]).
As soon as the motor is switched on, conveyed media is suctioned on the suction
side connection (1).
When it enters the side-channel the conveyed media is accelerated in the direc-
tion of rotation by the blades of the rotating impeller (3).
The centrifugal force presses the conveyed media to the inner wall of the side-
channel (2). From there, the conveyed media is supplied to the impeller blades
again.
With every renewed entry of the conveyed media into the impeller, it gains kinetic
energy and the pressure increases.
The cross section of the side-channel is limited at the interrupter.
In this manner, the conveyed media is stripped from the impeller blades and ex-
pelled via the discharge-side connection (4).

Transportation with a crane
!All single-stage G-BH2 are equipped with an eye bolt (item 15, Structure [➙
13]) and all two and three-stage G-BH2 are equipped with a lifting attach-
ment (item 15, Structure [➙13]). The eye bolt or lifting attachment is exclu-
sively designed for the mass of the G-BH2, including the original accessories
(except for the in-line filter, item 51, Structure [➙13]).
1. Detach the fitted in-line filter before transportation of the G-BH2.
2. Check that the eye bolt or lifting attachment is firmly fastened and retighten
as necessary.
Tightening torque of eye bolt: M12 18 - 22 Nm [13.3 - 16.2 ft lbs].
3. Attach the crane hook to the eye bolt or lifting attachment.
4. Lifting and transporting the G-BH2.
5. Place the G-BH2 down and, if necessary, secure from slipping and falling.
6. Remove the crane hook after transportation.
Storage
NOTICE
Mechanical damage and corrosion!
Failure to adhere to the storage conditions can lead to mechanical damage
and corrosion or can shorten the re-greasing interval.
1. Adhere to the storage conditions.
2. The maintenance intervals of the ball bearings (Maintenance [➙38]) become
shorter as the time of storage increases.
1. Connect all suction vents so that no dirt or solid particles can enter.
2. Turn the rotor once per year so as to avoid permanent standstill marks.

Measures after long-term storage
Replace ball bearings and radial shaft seal
!When the length of storage until assembly is exceeded by 4 years for the
storage conditions provided in Storage [➙18].
1. Replace the rolling bearing.
2. Clean adjacent bearing areas for open ball bearings and re-grease.
3. Replace and grease the radial shaft seal.
If the bearing conditions vary (Storage [➙18]), a reduced ball bearing service life
is to be expected.
Measuring the motor insulation resistance
Measuring the motor insulation resistance.
Value >1 kΩ per volt of measured voltage: no measures necessary.
Value ≤1 kΩ per volt of measured voltage: Dry winding.
Mounting conditions
At the place of assembly,
▪Adhere to the Permitted conditions for use [➙43].
▪No outlet air from other machines in the suction area of the motor fan or auxil-
iary ventilator.
▪Provide ventilation facilities, so that the permissible Maximum temperatures
[➙43] are not exceeded.
▪Sufficient room is provided for installation and removal of pipelines and main-
tenance and repair work, particularly for removing and installing the G-BH2.
▪Provide an even, stable installation surface or base frame whose dimensions
and load-bearing capacity are designed for the G-BH2.
▪The maximum tolerance for the evenness of the assembly surface is 0.5 mm
[0.197 in].
▪External oscillations >1.5 mm/s [0.06 in/s], linear accelerations >3 m/s2
[9.85 ft/s2] as well as shock loads or rotary accelerations are not permitted.
▪When installing outdoors, protective measures against the effects of weather
such as rain, direct sunlight, lightening, snow or ice (e.g. a protective roof)
must be provided.
▪External mechanical loads are not permitted on the G-BH2 and its attach-
ments (e.g. piping without support, ascending the G-BH2 and its attachments)
▪For installation in enclosed spaces and for conveyed media other than air,
leaks from the G-BH2 must be considered.
▪When operating without silencers and direct extraction from the environment
or direct discharge into the environment, effective noise protection measures
must be provided.
▪When there is a risk of condensation formation in the internal space of the G-
BH2, provide suitable protection measures (e.g. heating, upstream moisture
separators, continue running G-BH2).
▪For G-BH2 with a condensate drain hole, the condensate can always escape
freely under the fan guard (item 8, Structure [➙13]). If necessary, provide
suitable measures to prevent condensate from escaping.

Reduction of oscillations and noises
Noise emissions and vibrations can be reduced by the following measures.
▪Do not set up the G-BH2 in set-up areas that conduct or radiate sound.
▪Equip installation surfaces with intermediate layers of noise damping material.
▪Use additional silencers (accessory).
▪Use spring elements (accessory) for horizontal assembly.
It is recommended to flexibly set up the G-BH2 on springs elements.
Set up
The G-BH2 must always be screwed to a fixed installation surface (e.g. floor, wall,
ceiling) or a base frame.
The following assembly options are permitted:
▪Horizontal assembly on the foot (item 4, Structure [➙13]).
▪Vertical assembly on the compressor cover (item 14, Structure [➙13]).
▪Assembly on the wall or ceiling:
– Hanging horizontally on the foot:
– Hanging vertically on the foot with the compressor cover facing down-
wards
Exceptions
▪2BH20...-...N/1/2/3/4 may only be assembled horizontally on the foot.
▪2BH20780-2A..P/Q/R and 2BH20780-3A..P/Q/R may only be assembled hori-
zontally on the foot.
