7.4 Inspection before assembly
7.4.1 Installation site
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.
7.5 Installing the compact booster unit
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.
7.6 Installing the pipelines
7.6.1 Connecting the overflow
1. Lead the pipeline to the drain.
7.6.2 Installing the compensator (optional)
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.
7.7 Buffer tank
7.8 Protection against dry running
7.9 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.
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.
Warning
The system is top heavy
ª
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.
v
To avoid the transfer of pipeline forces and structure-borne sound to the
compact booster unit, it is recommended to install compensators with a
tie bar.
Always install pipelines so that they are free of tension.
The use of compensators with tie bars (refer to the accessories section)
is recommended.
Caution
Overflow not connected
ª
Danger of flooding the installation room!
Lead the overflow line to a drain with adequate dewatering
capacity (connection DN150).
If kompensators 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
ª
Fire hazard!
Take approriate measures to protect the compensator during
welding work in the vicinity.
Caution
Leaky compensator
ª
Danger of flooding the installation room!
Check regularly for rips and blisters, exposed material or other
defects.
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.
Danger
Contamination of potable water
ª
Danger to life!
If the inlet line from the house connection to the buffer tank is
longer than 10x DN and/or the maximum volume is larger than
1.5l, then the inlet has to be rinsed at least once a week with
three times the pumped volume at a minimum flow rate of
0.2 m/s and a nominal width of over DN50 and 0.1 m/s at
anominal width of over DN50.
Setting the rinsing duration
Caution
Dirt in the system
ª
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 madeof polyethylene fulfils the requirements of
EN 1717 and EN 13077, with free drain type AB.
The protection against dry running is only active in manual and testing
modes. In the automatic operation mode only one message is sent, the
pump continues to run.
The switch cabinet has a digital input for this purpose. It is hard-wired
with a floating switch in the buffer tank. The power-off delay can be set
from 5 to 100 s on the relay. The default setting is 10s.
