3. Product description3.1 General description
Grundfos Hydro Micro-E booster systems are designed for the pressure boosting of clean water in blocks of flats, hotels, hospitals, schools, etc.
Hydro Micro-E incorporates Grundfos CME-A pumps fitted with frequency-controlled single-phase MGE motors and a breaker box.
Hydro Micro-E maintains a constant pressure through continuously variable adjustment of the speed of the pumps connected.
It adjusts its performance to the demand through cutting in or out the required number of pumps and through parallel control of the pumps in operation.
It performs automatic pump changeover according to the principle "first in, first out" (FIFO).
Hydro Micro-E has been factory-assembled and tested with the control parameters mentioned in the quick guide supplied with the booster system.
3.2 Functions
Hydro Micro-E offers the following functions:
• multi-master function

5. Operating conditions5.1 Temperatures
5.1.1 Ambient temperature during storage and transportation
Minimum -30 °C
Maximum +60 °C.
5.1.2 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.
5.1.3 Liquid temperature
Minimum 0 °C
Maximum 60 °C.
5.2 Installation altitude
Installation altitude is the height above sea level of the installation site.
• Motors installed up to 1000 m above sea level can be loaded 100 %.
• Motors installed more than 1000 m above sea level must not be fully loaded due to the low density and consequent low cooling effect of the air. See fig. 2.
Fig. 2 Derating of motor output power (P2) in relation to altitude above sea level
5.3 Relative air humidity
Maximum 95 %.
5.4 Maximum operating pressure
See nameplate.
5.5 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, i.e. every time the operating conditions change, a new run-in period will be started.
Under normal conditions, the leaking liquid will evaporate. As a result, no leakage will be detected.
5.6 Minimum inlet pressure
Fig. 3 Parameters for the calculation of minimum inlet pressure
The minimum inlet pressure "H" in metres head required to avoid cavitation in the pumps can be calculated as follows:
H = pb x 10.2 - NPSH - Hf - Hv - Hs
If the calculated "H" is positive, the individual pump can operate at a suction lift of maximum "H" metres head.
If the calculated "H" is negative, a minimum suction head of "H" metres is required during operation.
Caution The motors must not be installed more than 2000 m above sea level.

pb = Barometric pressure in bar.(Barometric pressure can be set to 1 bar.)
In closed systems, pb indicates the system pressure in bar.
NPSH = Net Positive Suction Head in metres head(to be read from the NPSH curves in the installation and operating instructions for the pumps).
Hf = Friction loss in suction manifold in metres head at the highest flow the individual pump will be delivering.
Note: If a non-return valve is installed on the suction side of the pump, the friction loss in the valve must be added. See the manufacturer's data.
Hv = Vapour pressure in metres head. See page 23.
tm = liquid temperature.

Example
pb = 1 bar.
Pump type: CRE 15, 50 Hz.
Flow rate: 15 m3/h.
NPSH (from page 23): 1.2 m head.
Hf = 3.0 m head.
Liquid temperature: +60 °C.
Hv (from page 23): 2.1 m head.
H = pb x 10.2 - NPSH - Hf - Hv - Hs [m head].
H = 1 x 10.2 - 1.2 - 3.0 - 2.1 - 0.5 = 2.8 m head.
This means that each pump can operate at a suction lift of maximum 2.8 m head.
Pressure calculated in bar: 2.8 x 0.0981 = 0.27.
Pressure calculated in kPa: 2.8 x 9.81 = 27.4.
5.7 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.
5.8 Minimum flow rate
Due to the risk of overheating, the pumps should not be used at flows below 10 % of the rated flow of one pump.
5.9 Start/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.
5.10 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.
We recommend to use nitrogen gas for precharging.
6. Installation
6.1 Location
Observe the following points to ensure adequate cooling of motor and electronics:
• Position Hydro Micro-E in such a way that adequate cooling is ensured.
• Keep motor cooling fins and fan blades clean.
Hydro Micro-E is not suitable for outdoor installation.
The booster system must have 1 m clearance in front and on the two sides.
6.2 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 suction and discharge pipes to avoid resonance. See fig. 4.
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, we recommend to fit pipe supports on the suction and discharge pipes to prevent vibration being transmitted through the pipework. See fig. 4.
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 foundation.
Fasten the pipes to parts of the building to ensure that they cannot move or be twisted.
Fig. 4 Installation example with expansion joints and pipe supports
The expansion joints and pipe supports shown in fig. 4 are not included in the standard Hydro Micro-E.
NoteThe pumps must not run against a closed discharge valve.
NoteMeasure the precharge pressure while the system is pressureless.

11. Multi-master function11.1 Systems with one discharge-pressure sensor
To enable the system to deliver a constant pressure, a discharge-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 discharge-pressure sensor to one of the other pumps and configure it with Grundfos GO. The system can now be restarted.
11.2 Systems with two or more discharge-pressure sensors
If two or more pumps in the system are configured with discharge-pressure sensors, they can all function as master pump. 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.
12. Protective functionsIt 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 a discharge-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 a discharge-pressure sensor. Alternatively, an additional sensor per pump with discharge-pressure sensor can be installed.
12.1 Dry-running protection
Dry-running protection is achieved via a level switch fitted in a water tank. See section 6.4 Dry-running protection.
12.2 Level switch
The system can be 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 suction manifold and be connected to one of the digital inputs. See section 6.4 Dry-running protection
Furthermore, the digital input must be configured with a Grundfos GO to detect dry running.
The system must be restarted manually if it has been stopped due to dry running.
13. Bus signal 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.
NoteHydro Micro-E must be protected against dry running.
NoteIf a bus signal is used, the number of settings available via Grundfos GO will be reduced.

14. Priority of settingsThe system can always be set to operation at maximum speed or to stop with Grundfos GO.
If two or more functions are enabled at the same time, the system will operate according to the function with the highest priority.

17. Digital inputHydro Micro-E has a digital input for external fault. The input has been factory-set to external fault and the input is a normally-open contact.
Functional diagram: input for digital function
If the digital input is active for more than 10 seconds, Hydro Micro-E will stop because of an external fault.
The digital input is used for the dry-running protection.
18. Data communicationIt 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.
