2. Scope of these instructions

These installation and operating instructions apply to the
Grundfos Hydro Multi-E booster systems.
Hydro Multi-E is a range of factory-assembled booster systems,
ready for installation and operation.

4. Product description

4.1 General description

The Grundfos Hydro Multi-E booster systems are designed for
pressure boosting of clean water in blocks of flats, hotels,
hospitals, schools, etc.
Hydro Multi-E incorporates Grundfos CRE, CRIE, CME-A or
CME-I pumps with integrated frequency-controlled single- or
three-phase MGE motors and a breaker cabinet.
The system maintains a constant pressure through continuous
variable adjustment of the speed of the pumps connected.
The system adjusts its performance to the demand by cutting the
required number of pumps in or out and by parallel control of the
pumps in operation.
The system has been factory-assembled and tested with the
control parameters mentioned in the quick guide supplied with the
booster system.

4.2 Functions

Hydro Multi-E offers the following functions:
• multi-master function
• constant pressure
• redundant sensor
• stop at low flow
• cascade control of pumps
• automatic alternation
• pipe filling
• limit-exceeded function
• two digital inputs
• two digital outputs
• two analog inputs
• optional bus communication via Grundfos CIM modules.

Tips and advice that make the work easier.

The system in which Hydro Multi-E is incorporated
must be designed for the maximum pump pressure.
