2. Product introduction

CMBE is a high-efficiency compact booster suitable for clean water
supply and pressure boosting in domestic and light commercial
applications. It keeps a constant pressure via the integrated speed
control.

2.1 Intended use

The product has been evaluated for use in indoor installations with:
• clean water
• drinking water.
Only use the product according to the specifications
stated in these installation and operating instructions.
Check local regulations.

2.2 Pumped liquids

The product is suitable for pumping clean, thin, non-aggressive,
non-toxic and non-explosive liquids without solid particles or fibres.
If the water contains sand, gravel or other debris, there is
a risk of pump blockage and pump damage.
Please install a filter on the inlet side or apply a floating
strainer to protect the pump.

The product must only be connected to protected network
subnets with strict access control.
According to the standard EN 18031-1:2024, the RJ45 connector
used for connecting to IP networks is considered an exposed
network interface, along with the GENIbus TCP protocol used on
it, which is considered an exposed service.

RJ45 Pairing is required before
TCP
communication can take place.
The GENIpro TCP pairing state is
persistent.

2.4 System sizing

The system in which the CME Booster is incorporated
must be designed for the maximum pump pressure.
The pump is by default set to not stop until it reaches its maximum
pressure.
