7.1 Temperatures

7.1.1 Ambient temperature during storage and transportation

Minimum -30 °C Maximum +60 °C.

7.1.2 Ambient temperature during operation

Minimum -20 °C Maximum +50 °C. The motors can operate with the rated output power (P2) at 50

°C, but continuous operation at higher temperatures will reduce the expected product life. If the motors are to operate at ambient temperatures between 50 and 60 °C, oversized motors must be selected. Contact Grundfos for further information.

7.1.3 Liquid temperature

0 to +60 °C.

7.2 Installation altitude

Do not install the motors more than 2000 metres above sea level.

Installation altitude is the height above sea level of the installation site.

• Motors installed up to 1000 metres above sea level can be loaded 100 %.

• Motors installed more than 1000 metres above sea level must not be fully loaded due to the low density and consequent low cooling effect of the air. See fig. 3.

7.3 Relative humidity

Maximum 95 %.

7.4 Maximum operating pressure

See system nameplate.

7.5 Shaft seal run-in

The seal faces are lubricated by the pumped liquid, meaning that there may be a certain amount of leakage from the shaft seal.

When the pump is started up for the first time, or when a new shaft seal is installed, a certain run-in period is required before the leakage is reduced to an acceptable level. The time required for this depends on the operating conditions, that is every time the operating conditions change, a new run-in period will be started.

Under normal conditions, the leaking liquid evaporates. As a result, a leakage will not be detected.

7.6 Minimum inlet pressure

Fig. 4 Parameters for the calculation of minimum inlet

pressure

English (GB)

TM02 0118 3800

The minimum inlet pressure "H" in metres head required to avoid cavitation in the pumps can be calculated as follows:

Hydro Multi-E with CME pumps

H = pb x 10.2 - NPSH - Hf - Hv - Hs

pb = Barometric pressure in bar. Barometric pressure can

be set to 1 bar. In closed systems, p

bar.

NPSH = Net Positive Suction Head in metres head

The NPSH value can be read from the NPSH curve at the highest flow which the individual pump will be delivering.

Hf = Friction loss in inlet manifold in metres head at the

TM05 6400 4712

Fig. 3 Derating of motor output power (P2) in relation to

Hv = Vapour pressure in metres head.

Hs = Safety margin of min. 0.5 metres head.

Hydro Multi-E systems with CME pumps always require a positive inlet pressure, both during startup and operation.

highest flow the individual pump will be delivering. Note: If a non-return valve is installed on the inlet side

of the pump, the friction loss in the valve must be added. See the manufacturer's data.

In some regions, the booster system is available with a low inlet manifold which makes it more suitable for suction lift operation. Contact Grundfos for further information.

indicates the system pressure in

Example

English (GB)

pb = 1 bar.

Pump type = CRE 15, 50 Hz.

Flow rate = 15 m

NPSH (from page 23) = 1.2 metres head.

Hf = 3.0 metres head.

Liquid temperature = +60 °C.

Hv (from page 24) = 2.1 metres head.

H = pb x 10.2 - NPSH - Hf - Hv - Hs [metres head].

H = 1 x 10.2 - 1.2 - 3.0 - 2.1 - 0.5 equal to 2.8

This means that each pump can operate at a suction lift of maximum 2.8 metres head.

Pressure calculated in bar: 2.8 x 0.0981 equal to 0.27. Pressure calculated in kPa: 2.8 x 9.81 equal to 27.4.

metres head.

7.7 Maximum inlet pressure

The maximum inlet pressure must not exceed 8 bar. However, the actual inlet pressure plus pressure when the pump is operating against a closed valve must always be lower than the maximum operating pressure.

7.8 Minimum flow rate

Due to the risk of overheating, the pumps should not be used at flow rates below 10 % of the rated flow rate of one pump.

The pumps must not run against a closed outlet valve.

8. Installation

8.1 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.

• Keep motor cooling fins and fan blades clean.

Hydro Multi-E is not suitable for outdoor installation. The booster system must have a 1-metre clearance in front and

on the two sides.

8.2 Mechanical installation

Arrows on the pump base show the direction of flow of water through the pump.

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. 5.

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 prior to startup. 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 pipe hangers on the inlet and outlet pipes to prevent vibration being transmitted through the pipes. See fig.

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.

Fasten the pipes to parts of the building to ensure that they cannot move or be twisted.

7.9 Start and stop

The system must not be started and stopped via the power supply more than four times per hour.

When the system is switched on via the power supply, it will start after approx. 5 seconds.

7.10 Diaphragm tank

The diaphragm tank precharge pressure must be set to 0.7 x setpoint.

If the setpoint is changed, the diaphragm tank precharge pressure should be changed accordingly to ensure optimum operation.

Measure the precharge pressure while the system is pressureless.

We recommend that you use nitrogen gas for precharging.

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.

8.3.1 Protection against electric shock, indirect contact

8.4 Mains supply

Check that the supply voltage and frequency correspond to the values stated on the nameplate.

Use dedicated IT network motors if the booster system is supplied through an IT network. Contact Grundfos.

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.

English (GB)

8.5.1 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:

When an earth leakage circuit breaker or ground fault circuit interrupter is selected, the total leakage current of all the electrical equipment in the installation must be taken into account.

The leakage current of Hydro Multi-E can be found in section

25.2 Leakage current.

8.5.2 Systems with three-phase motors

• 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:

9. Startup

Do not start the pumps until they have been filled with liquid.

9.1 Hydro Multi-E in system with positive inlet pressure

1. Check that Hydro Multi-E corresponds to order and that no

single parts have been damaged.

2. Switch off the power supply with the main switch.

3. Switch off the circuit breakers of all pumps.

4. Check that the precharge pressure in the diaphragm tank is

0.7 times the required outlet pressure (setpoint).

Measure the precharge pressure while the system is pressureless.

5. Connect water and power supplies to the system.

6. Open all pump inlet and outlet valves.

7. Vent all pumps by means of the vent screws.

When an earth leakage circuit breaker or ground fault circuit interrupter is selected, the total leakage current of all the electrical equipment in the installation must be taken into account.

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.

13. Multi-master function

A B

English (GB)

13.1 Systems with one outlet-pressure sensor

To enable the system to deliver a constant pressure, an outlet-pressure sensor must be connected to and configured on at least one of the pumps. The pump with this sensor will function as master pump and control the system.

If the master pump is switched off or stopped due to an alarm, the other pumps in the system will stop.

If it is not possible to remove the cause of the alarm on the master pump, another pump can function as master pump. Connect the outlet-pressure sensor to one of the other pumps and configure it with Grundfos GO Remote. The system can now be restarted.

13.2 Systems with two or more outlet-pressure

sensors

If two or more pumps in the system are configured with an outlet-pressure sensor, they can all function as master pumps. As standard, the pump with the lowest number will be the master pump. From factory, the master pump is marked with number 1.

If master pump 1 is switched off or stopped due to an alarm, one of the other master pumps will automatically take over the control of the system.

14. Protective functions

It is important that any protective function, for example dry-running protection or external start/stop that is detected via a digital input, is connected to and configured on all the pumps with an outlet-pressure sensor.

If an additional sensor is used, for example for the limit-exceeded function or setpoint influence, this sensor must also be connected to all pumps with an outlet-pressure sensor. Alternatively, an additional sensor per pump with an outlet-pressure sensor can be installed.

14.1 Dry-running protection

Hydro Multi-E must be protected against dry running.

Types of dry-running protection:

• a pressure switch which is factory-fitted to the inlet manifold. See section 14.1.1 Pressure switch.

• a level switch fitted in a water tank. See section 14.1.2 Level

switch.

14.1.1 Pressure switch

As standard, Hydro Multi-E is fitted with an adjustable pressure switch as dry-running protection. The pressure switch is fitted to the inlet manifold.

If the inlet pressure is below the lower switching point, the system cannot start.

If the pressure switch has stopped the system during operation due to the inlet pressure being too low, the inlet pressure must increase to a pressure that is higher than the setting of the upper switching point before the system can restart.

If necessary, adjust the lower switching point by turning screw A and adjust the upper switching point to a value higher than the lower switching point by turning screw B. See fig. 19.

Do not set the lower switching point to a value below the minimum inlet pressure. See section

7.6 Minimum inlet pressure.

The system can be optionally fitted with a level switch, either from factory or after delivery. The level switch can for instance monitor the water level in a tank connected to the inlet manifold and be connected to one of the digital inputs. See section Advanced

functional module (FM 300).

Furthermore, the digital input must be configured with a Grundfos GO Remote to detect dry running.

The system must be restarted manually if it has been stopped due to dry running.

15. Bus signal

English (GB)

Bus communication is enabled via an RS-485 input. The communication is carried out according to the Grundfos

GENIbus protocol and enables connection to a building management system or another external control system.

Via a bus signal, it is possible to remote-set motor operating parameters, such as setpoint and operating mode. At the same time, the motor can, via the bus, provide status information about important parameters, such as actual value of control parameter, input power and fault indications.

Contact Grundfos for further information.

If a bus signal is used, the number of settings available via Grundfos GO Remote will be reduced.

16. Priority of settings

The system can always be set to operate at maximum speed or to stop with Grundfos GO Remote.

If two or more functions are enabled at the same time, the system will operate according to the function with the highest priority.

Example: If, via the digital input, the system has been set to maximum speed, the pump control panel or Grundfos GO Remote can only set the system to "Manual" or "Stop".

The priority of the settings appears from the table below:

Priority Start/stop button

1Stop 2Stop* 3 Manual 4 Max. speed* 5 Stop 6 Stop 7 Max. speed 8 Min. speed

9 Start 10 Max. speed 11 Mi n . spee d 12 Min. speed 13 Start 14 Start

* If the bus communication is interrupted, the system will

resume its previous operating mode, for example "Stop", selected on the control panel of the pump running as master or with Grundfos GO Remote.

21. Insulation resistance

Do not measure the insulation resistance of motor windings or an installation incorporating motors with integrated frequency converters using high-voltage megging equipment, as this may damage the built-in electronics.

22. Maintenance

DANGER

Electric shock

Death or serious personal injury

- Switch off the power supply and wait at least five minutes before you start any work on the product. Make sure that the power supply cannot be accidentally switched on.

English (GB)

If the digital input is active for more than 10 seconds (s), Hydro Multi-E will stop because of an external fault.

The digital input is used for the dry-running protection.

20. Data communication

It is possible to connect the system to an external network. The connection can be made via a GENIbus-based network or a network based on another fieldbus protocol.

The system can communicate via CIM modules. This enables the system to communicate with different types of network solutions.

A CIM module is an add-on communication interface module. The CIM module enables data transmission between the pump and an external system, for example a BMS or SCADA system.

For further information on CIM modules, see www.grundfos.com (Grundfos Product Center) or contact Grundfos.

22.1 Pumps

Pump bearings and shaft seals are maintenance-free. If CRE or CRIE pumps are to be drained for a long period of

inactivity, remove one of the coupling guards to inject a few drops of silicone oil on the shaft between the pump head and the coupling. This will prevent the shaft seal faces from sticking.

22.2 Motors

Keep motor cooling fins and fan blades clean to ensure sufficient cooling of the motor and electronics.

22.3 Breaker cabinet

The breaker cabinet is maintenance-free. Keep it clean and dry.

23. Shutdown

Shut down the system with the main switch in the breaker cabinet.

DANGER

Electric shock

Death or serious personal injury

- Do not touch the conductors in front of the main switch as they are still energised.

To shut down a pump, switch off the circuit breaker of the pump.

23.1 Frost protection

If pumps are not used during periods of frost, they must be drained to avoid damage.

Drain the pump by loosening the vent screw in the pump head and removing the drain plug from the base.

Do not tighten the vent screw or refit the drain plug until the system is to be used again.

23.2 Service kits

See Grundfos Product Center for service manuals.
