5.3 Connecting pipeline
CAUTION!
Airbag formation in the suction line
Compact booster unit can not suck in any medium!
Install the pipeline rising
Fig. 4 Correct connection of the pipeline
The use of compensators with tie bars is recommended.
1.
Always install pipelines so that they are free of
tension.
2.
Pipeline with discharge pressure lines with the
distribution lines on the backfeed and discharge side.
5.3.1 Installation of pipeline compensator
DANGER!
Sparks and radiant heat
Fire hazard!
Take appropriate measures to protect the
compensator during welding work in the vicinity.
CAUTION!
Leaky compensator
Flooding the installation room.
Check regularly for rips and blisters, exposed material
or other defects.
The compensator is provided with a structure-borne sound
insulation to intercept the length limitation to absorb any
reaction forces.
1.
Install the compensator in the pipeline without tension.
2.
Fasten bolts equally cross-wise.
3.
Do not paint the compensator and always protect it
against oil.
4.
The compensator has to be accessible on the
compact booster unit at any time for inspection
purposes and for this reason should not be included in
the pipe insulation.
5.
The compensator is subject to wear.
5.4 Electrical connection
HAZARDOUS VOLTAGE!
Unqualified persons working on the compact
booster unit
Danger to life from electric shock!
Work on electrical equipment may only be performed
by specialist electric technicians.
Observe IEC 60364 regulations.
HAZARDOUS VOLTAGE!
Faulty mains connection
Damage to the electricity network, short circuit!
Observe the conditions for technical connections of
the local power supply companies.
The diameter of the electrical supply line has to be
determined according to the total connection value.

6.1 Commissioning
6.1.1 Start-up requirements
CAUTION!
Dry running pump
Damage of the pump / Compact booster unit
If the dry running protection is deactivated, then the
operator takes responsibility in the case of dry
running.
Before start-up of the compact booster unit, the following
points have to be ensured:
•
The compact booster unit is electrically connected to
all protective devices in accordance with the
regulations.
•
The relevant VDE and country-specific regulations
have to be adhered to and fulfilled.
6.1.2 Fill up and vent the compact buster
unit
CAUTION!
The pipeline is not free of residue
Damage of the pump / Compact booster unit
Before start-up (and testing) make sure that pipelines
and compact booster unit are free of residues.
The compact booster unit is hydraulically tested with
water and then emptied before delivery .The
whereabouts of residual water is technically
unavoidable.
Remove the caps of the connection openings shortly
before installation
Before start-up of the compact booster unit, observe
EN 806.
After long service life, a rinse or professional
disinfection is recommended.
For larger or widely branched piping systems, the
rinsing of the compact booster unit can be done
locally.
Floating ring seals may briefly show signs of leakage
during start-up, but no longer after a short period of
operation.
