Danger to life!
The compact booster unit has to be voltage free for all repairs
and maintenance work. Turning off the system with the motor
protection switch does not securely shut off the motor inlet lines.
Only perform maintenance work on the compact booster unit if
you are sure that the compact booster unit is free of power.
Secure the compact booster unit against being switched on
unintentionally.
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 maintaining the compact
booster unit and secure it from being turned on.
Warning
Components and lines under pressure
Personal and property damage!
Before work is done on pressure-retaining components, the
pump has to be depressurised!
Disconnect the pump from the power supply!
Warning
Hot surfaces of the pump housing
Danger of burning!
The pump housing has to be at ambient temperature!
Warning
Inappropriate lifting/moving of heavy modules or components

Caution
Inappropriately maintained compact booster unit
The proper function of the compact booster unit can no longer be
ensured!
Maintain the compact booster unit regularly.
Set up a maintenance schedule for the compact booster unit
that focuses especially on the pump lubrication, shaft seal and
clutch.
Always observe the safety regualations and instructions.

In case of damage, please contact our service department.
Setting up a maintenance schedule reduces the effort for maintenance
to a minimum and helps you avoid expensive repairs and you can work
on your compact booster unit reliably and without any problems.

required inspections have to be conducted on time.
8.2.1 Buffer tank
Danger
Contamination of potable water
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
Damage to the pumps!
Rinse the tank before filling it.
Rinse the tank and the integrated odour trap regularly.
1. Rinse the inlet to the buffer tank if necessary.
2. Rinse the tank and the integrated odour trap regularly.
