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

- Use safety equipment when mounting the base

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.

Fig. 11 Example of a mains-connected Hydro Multi-E with

backup fuses and additional protection (applies only

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

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.
