7.3 Inspection before assembly
7.3.1 Installation site
Sufficient noise insulation for the building is ensured due the compact
booster unit`s safety store.
The system has to be installed above the flood level. Provide a suitable
lifting device for underfloor installation.
1. Inspect the building architecture.
- The architecture of the building has to be prepared according to the data
sheets.
- The concrete foundation is true to size and completely solid.
7.4 Installing the compact booster unit
Warning
The system is top heavy
Danger of injury!
Secure the system so that it cannot tip over before it has been
permanently anchored.
Anchor the system securely to the foundation.
Make allowance for space for operating and maintenance tasks.
1. Remove the packaging before installing the system.
2. Connect the system refilling and discharge pressure lines with the distri-
bution lines on the refilling and discharge side (DIN 1988).
3. Mark the installation holes on the floor as desribed in the data sheet.
4. Drill holes (maximum Ø12 mm).
5. Insert suitable, proper sized dowels.
6. Position the system for installation.
7. Anchor the system solidly to the foundation with adequate bolts.
To avoid the transfer of pipeline forces and structure-borne sound to the
compact booster unit, it is recommended to install compensators with a
v
tie bar.
7.5 Installing the pipelines
Always install pipelines so that they are free of tension.
The use of compensators with tie bars (refer to the accessories section)
is recommended.
7.5.1 Connecting the overflow
Caution
Overflow not connected
Danger of flooding the installation room!
Lead the overflow line to a drain with adequate dewatering
capacity (connection DN150).
1. Lead the pipeline to the drain.
7.5.2 Installing the compensator (optional)
If compensators are used to damper vibrations, their durability has to be
ascertained.
Compensators have to be able to be easily replaced.
Danger
Sparks and radiant heat
Fire hazard!
Take approriate measures to protect the compensator during
welding work in the vicinity.
Caution
Leaky compensator
Danger of flooding the installation room!
Check regularly for rips and blisters, exposed material or other
defects.
1. Install the compensator in the pipeline without tension.
- Never correct misalignment and offset pipes with the compensator.
2. Fasten bolts equally cross-wise.
- The bolt ends should not protrude from the flange.
Do not paint the compensator and always protect it against oil.
The compensator has to be accessible on the compact booster unit at
any time for inspection purposes and for this reason should not be inclu-
ded in the pipe insulation.
The compensator is subject to wear.

7.6 Buffer tank
Caution
Dirt in the system
Damage to the pumps!
Rinse the tank before filling it.
Rinse the tank and the integrated odour trap regularly.
The DIN 1988 allows for the installation of a pressure-free buffer tank
together with the compact booster unit. The same regulations apply for
their installation as for the compact booster unit.
The buffer tank made of polyethylene fulfils the requirements of
EN 1717 and EN 13077, with free drain type AB.
7.7 Installing valves
All additional valves in the terminal lines such as sliders, water meters and
check valves have to be dimensioned according to the values stipulated by
the competent water distribution company.
7.8 Electrical connection
7.8.1 Safety instructions
Danger
Danger of injury from electric voltage.
High shock currents and burns from direct and indirect contact with
live parts.
Turn off the power supply before assembling the compact
booster unit and secure it from being turned on.
Non- or erroneously-connected cables
Malfunctions, which endanger the safety of operating personnel.
Work on electrical equipment may only be performed by specia-
list electric technicians.
Observe regulation IEC 30364 (DIN VDE 0100) and for explo-
sion protection IEC 60079 (DIN VDE 0165).
Faulty mains connection
Damage to the electricity network, short circuit!
Observe the conditions for technical connections of the local
power supply companies.
Wrongly wired connections
Destruction of electrical / electronic components.
Work on electrical equipment may only be performed by specia-
list electric technicians.
Improperly connected wiring and lines (e.g. too small bend radius)
Smouldering and fires from cables.
Work on electrical equipment may only be performed by specia-
list electric technicians.
Live cable ends and components
Make sure the protective earth system is connected throughout.
7.8.2 Connection specifications
Power supply connection
The circuit diagrams of the respective systems are kept in the switching
device and should always remain there. The documentation included
with the switch cabinet contains a list of electronic parts. Please always
specify the circuit diagram number when ordering spare electronic
parts.
The diameter of the electrical supply line has to be determined according
to the total connection value.
7.9 Standby indicator
The system standby mode has to be registered by the operator or their
contractors at the responsible authority (most commonly WVU or factory
inspectorate). Before starting the system, the author has to certify that the
prerequisites for connection are fulfilled.
Before the system is connected to the mains power supply, the operator has
to read the relevant VDE regulations.
The electrical supply lines must only be installed by companies that are
authorised to do such work.
