6. Installation
6.1 Location
Observe the following to ensure adequate cooling of motor and
electronics:
• Position Hydro Multi-E in such a way that adequate cooling is
ensured. See section 6.2.1 Ensuring motor cooling
• The ambient temperature must not exceed 50 °C.
• Keep motor cooling fins and fan blades clean.
The booster system must have a 1-metre clearance in front and
on the two sides.
6.2 Mechanical installation
Arrows on the pump base show the direction of the flow of water
through the pump.
1. The pipes connected to the booster system must be of
adequate size. Fit expansion joints in the inlet and outlet pipes
to avoid resonance. See fig. 8.
Connect the pipes to the manifolds of the booster system.
The manifold comes with a screw cap fitted to one end. If this end
is to be used, remove the screw cap, apply sealing compound to
the other end of the manifold, and fit the screw. Fit a blanking
flange with gasket on flanged manifolds.
Tighten up the booster system before starting it.
If booster systems are installed in blocks of flats or the first
consumer on the line is close to the booster system, we
recommend that you fit expansion joints on the inlet and outlet
pipes to prevent vibration being transmitted through the pipes.
See fig. 8.
2. Position the booster system on a plane and solid surface, for
example a concrete floor or foundation. If the booster system
is not fitted with vibration dampers, it must be bolted to the
floor or the foundation.
3. Fasten the pipes to parts of the building to ensure that they
cannot move or be twisted.
Fig. 8 Installation example with expansion joints and pipe
supports
The expansion joints and pipe supports shown in fig. 8 are not
included in the standard booster system.
6.2.1 Ensuring motor cooling
Leave at least 50 mm between the end of the fan cover and a wall
or other fixed objects. See fig. 9.
Fig. 9 Minimum distance (D) from the motor to a wall or other
fixed objects
6.3 Drain holes
When the motor is installed in moist surroundings or areas with
high humidity, the bottom drain hole must be open. If the humidity
is constantly high and above 85 %, open the drain holes in the
drive-end flange. The enclosure class of the motor will then be
lower. This helps prevent condensation in the motor as the motor
becomes self-venting, and it allows water and humid air to
escape.
The motor has a plugged drain hole on the drive side. You can
turn the flange 90 ° to both sides or 180 °.
Fig. 10 Drain holes
WARNING
Overhead load
Death or serious personal injury

6.4 Electrical installation
Carry out the electrical connection according to local regulations.
Check that the supply voltage and frequency correspond to the
values stated on the nameplate.
If the power supply cable is damaged, it must be replaced by the
manufacturer, the manufacturer's service partner or a similarly
qualified person.
The user or the installer is responsible for the installation of
correct earthing and protection according to local regulations. All
operations must be carried out by a qualified electrician.
The booster system must be stationary and installed permanently.
Furthermore, connect the booster system permanently to the
power supply.
Carry out the earth connection as duplicate conductors.
If the system cannot be installed with the supply disconnecting
device located minimum 0.6 m above service level according to
EN 60204-1 paragraph 5.3.4, install the system with an external
"supply disconnecting device" made according to EN 60204-1,
paragraph 5.3.2. The system must be provided with a means
permitting it to be locked in OFF (isolated) position.
6.4.1 Protection against electric shock, indirect contact
Protective-earth conductors must always have a yellow and
green (PE) or yellow, green and blue (PEN) colour marking.
Protection against mains voltage transients
The motor is protected against mains voltage transients in
accordance with EN 61800-3.
Motor protection
The motor requires no external motor protection. The motor
incorporates thermal protection against slow overloading and
blocking.
6.4.2 Insulation resistance
6.5 Mains supply
Check that the supply voltage and frequency correspond to the
values stated on the nameplate.
The wires in the breaker cabinet must be as short as possible.
Excepted from this is the separated earth conductor which must
be so long that it is the last one to be disconnected in case the
cable is inadvertently pulled out of the cable entry.
For maximum backup fuse, see section 25.1 Supply voltage.

6.6 Additional protection
6.6.1 Systems with single-phase motors
If Hydro Multi-E is connected to an electric installation where an
earth leakage circuit breaker (ELCB) or ground fault circuit
interrupter (GFCI) is used as additional protection, this circuit
breaker or interrupter must be marked with the following symbol:
The leakage current of Hydro Multi-E can be found in section
25.2 Leakage current.
6.6.2 Systems with three-phase motors
If Hydro Multi-E is connected to an electric installation where an
earth leakage circuit breaker (ELCB) or ground fault circuit
interrupter (GFCI) is used as additional protection, this circuit
breaker or interrupter must be of the following type:
• It must be suitable for handling leakage currents and cutting-in
with short pulse-shaped leakage.
• It must trip when alternating fault currents and fault currents
with DC content, i.e. pulsating DC and smooth DC fault
currents, occur.
For these systems an earth leakage circuit breaker or ground
fault circuit interrupter, type B, must be used.
This circuit breaker or interrupter must be marked with the
following symbols:
The leakage current of Hydro Multi-E can be found in section
26.2 Leakage current.
Protection against phase unbalance
The motors must be connected to a power supply with a quality
corresponding to IEC 60146-1-1, class C, to ensure correct motor
operation at phase unbalance.
This Also Ensures Long Life Of The Components.
6.7 Connection terminals
The descriptions and terminal overviews in this section apply to
both single- and three-phase motors.

mains-conducting parts by reinforced insulation and galvanically
separated from other circuits. All control terminals are supplied by
protective extra-low voltage (PELV) to ensure protection against
electric shock.
• Signal relay outputs
– Signal relay 1:
LIVE:
You can connect supply voltages up to 250 VAC.
PELV:
The output is galvanically separated from other circuits.
Therefore, you can connect the supply voltage or protective
extra-low voltage to the output as desired.
– Signal relay 2:
PELV:
The output is galvanically separated from other circuits.
Therefore, you can connect the supply voltage or protective
extra-low voltage to the output as desired.

• two analog inputs
• two digital inputs or one digital input and one open-collector
output
• Grundfos Digital Sensor input and output
• two signal relay outputs
• GENIbus connection.
See fig. 14.
• Inputs and outputs
All inputs and outputs are internally separated from the
mains-conducting parts by reinforced insulation and galvanically
separated from other circuits. All control terminals are supplied by
protective extra-low voltage (PELV) to ensure protection against
electric shock.
• Signal relay outputs
– Signal relay 1:
LIVE:
You can connect supply voltages up to 250 VAC to the
output.
PELV:
The output is galvanically separated from other circuits.
Therefore, you can connect the supply voltage or protective
extra-low voltage to the output as desired.
– Signal relay 2:
PELV:
The output is galvanically separated from other circuits.
Therefore, you can connect the supply voltage or protective
extra-low voltage to the output as desired.
• Mains supply (terminals N, PE, L or L1, L2, L3, PE).
Digital input 1 is factory-set to be the start-stop input
when open circuit results in stop. A jumper has been
factory-fitted between terminals 2 and 6. Remove the
jumper if digital input 1 is to be used as external
start-stop or any other external function.

9. Startup
9.1 Hygiene
Grundfos pressure booster systems are functionally tested by
running water through the system. During the test, Grundfos
continuously surveys the quality of the test water. Since it is not
possible to completely drain and dry the system after the test, the
system must be rinsed or flushed thoroughly before being taken
into use in a drinking water sector due to risk of bacteria growth.
This also applies if the system has been shut down for a long
period of time. Rinsing and flushing must always be done in
accordance with local regulations.
Contaminated drinking water endangers health.

12.3.1 Constant pressure
We recommend this control mode if the pump is to deliver a
constant pressure, independently of the flow in the system. See
fig. 37.
Fig. 37 "Constant pressure"
This control mode uses the factory-fitted pressure sensor, if any,
which measures the outlet pressure of the pump.
For pumps without a factory-fitted sensor, you must connect a
pressure sensor to one of the analog inputs of the pump. You can
set the pressure sensor in the Assist menu.

12.4 Pipe-filling function
This function is typically used in pressure-boosting applications,
and it ensures a smooth startup of systems with, for instance,
empty pipes.
Startup takes place over two phases. See fig. 39.
1. Filling phase.
The pipes are slowly filled with water. When the pressure
sensor of the system detects that the pipes have been filled,
phase two begins.
2. Pressure buildup phase.
The system pressure is increased until the setpoint is
reached. The pressure buildup takes place over a pressure
buildup period. If the setpoint is not reached within the given
time, a warning or an alarm can be given, and the pumps can
be stopped at the same time.
Fig. 39 Filling and pressure buildup phases
Setting range
• "Filling speed".
Fixed speed of the pump during the filling phase.
• "Flling pressure".
The pressure that the pump must reach before the maximum
filling time.
• "Max. filling time".
The time in which the pump must reach the filling pressure.
• Max. time reaction.
Reaction of the pump if the maximum filling time is exceeded:
– warning
– alarm (pump stops).
• "Pressure build-up time".
Ramp time from when the filling pressure is reached until the
setpoint must be reached.
