DANGER

Electric shock

Death or serious personal injury

- If national legislation requires a Residual-Current Device (RCD) or equivalent in the electrical installation, or if the pump is connected to an electric installation where an RCD is used as an additional protection, this must be type A or better, due to the nature of the pulsating DC leakage current. The RCD must be marked with the symbol shown below:

Fig. 4 Insulation of pump housing

Limit the heat loss from the pump housing and pipework.

The heat loss from the pump and pipework can be reduced by insulating the pump housing and the pipe. See fig.

As an alternative, polystyrene insulating shells can be fitted to the pump. See section

6.1 Product description.

Do not insulate the control box or cover the operating panel.

TM05 8561 2413

The pump requires no external motor protection.

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

7.1 Nameplate.

5.1 Before startup

Do not start the pump until the system has been filled with liquid and vented. The required minimum inlet pressure must be available at the pump inlet. See sections

TM05 8560 2613

Fig. 6 Venting of heating systems

Fig. 5 Venting the pump

The pump is self-venting. It need not be vented before startup. Air in the pump may cause noise. This noise will cease after a few

minutes running. Quick venting of the pump can be obtained by setting the pump to

speed III for a short period, depending on system size and design.

When the pump has been vented, i.e. when the noise has ceased, set the pump according to the recommendations. See section

10. Setting the pump.

The pump must not run dry.

The system cannot be vented through the pump. See section

5.3 Venting of heating systems.

The heating system can be vented via an air escape valve installed above the pump. When the heating system has been filled with liquid, follow this procedure:

1. Open the air escape valve.

2. Set the pump to speed III.

TM05 8000 1713

3. Let the pump run for a short period, depending on system size

and design.

4. When the system has been vented, that is when the possible

noise has ceased, set the pump according to the recommendations. See section

10. Setting the pump.

Repeat the procedure, if necessary.

The pump must not run dry.

6.2 Application

The GRUNDFOS ALPHA1 circulator pump is designed for the circulation of water in heating systems.

The pump is suitable for the following systems:

• underfloor heating systems

• one-pipe systems

• two-pipe systems. The pump incorporates a permanent-magnet motor and

differential-pressure control enabling continuous adjustment of the pump performance to the actual system requirements.

The pump has a user-friendly front-mounted operating panel. See sections

6.3 Advantages of installing a GRUNDFOS ALPHA1

The installation of a GRUNDFOS ALPHA1 means

easy installation and startup

• The pump is easy to install. With the factory setting, the pump can, in most cases, be started without making any settings.

high degree of comfort

• Minimum noise from valves, etc.

low energy consumption

• Low energy consumption compared to conventional circulator pumps.

Energy efficiency index (EEI)

• The Ecodesign directive for energy-using (EuP) and energyrelated (ErP) products is EU legislation requiring manufacturers to reduce the overall environmental impact of their products.

• The pumps are energy-optimised and comply with the EuP directive.

6.4 Intended use

GRUNDFOS ALPHA1 is suitable for

• systems with constant or variable flows where it is desirable to optimise the setting of the pump duty point.

• systems with variable flow-pipe temperature.

In these control modes, the pump performance and consequently the power consumption are adjusted according to the heat demand in the system.

Proportional-pressure control

In this control mode, the differential pressure across the pump is controlled according to the flow.

Bypass valve

The purpose of the bypass valve is to ensure that the heat from the boiler can be distributed when all valves in the underfloorheating circuits and/or thermostatic radiator valves are closed.

System elements:

• bypass valve

• flowmeter, pos. A. The minimum flow must be present when all valves are closed. The pump setting depends on the type of bypass valve used, i.e.

manually operated or thermostatically controlled.

Sound pressure level The sound pressure level of the pump is lower than 43 dB(A). Ambient temperature 0-40 °C Surface temperature The maximum surface temperature will not exceed 125 °C. Liquid temperature 2-110 °C

Electrical data

Supply voltage 1 x 230 V ± 10 %, 50/60 Hz, PE Insulation class F

Miscellaneous data

Motor protection The pump requires no external motor protection. Temperature class TF110 to EN 60335-2-51 Enclosure class IP42

To avoid condensation in the control box and stator, the liquid temperature must always be higher than the ambient temperature.

≤ 75 °C 0.005 MPa, 0.05 bar, 0.5 m head 90 °C 0.028 MPa, 0.28 bar, 2.8 m head 110 °C 0.108 MPa, 1.08 bar, 10.8 m head EMC Directive (2014/30/EU).

Standards used: EN 55014-1:2006/A1:2009/A2:2011, EN 55014-2:2015, EN 61000-3-2:2014 and EN 61000-3-3:2013.

The pump can run at ambient temperatures higher than the liquid temperature if the plug connection in the pump head is pointing downwards

If the temperature of the pumped liquid is lower than the ambient temperature, make sure that the pump is installed with the pump head and plug in position 6 o'clock.

15.1 Guide to performance curves

Each pump setting has its own performance curve (QH curve). A power curve (P1 curve) belongs to each QH curve. The power curve shows the pump power consumption (P1) in Watt at a given QH

curve. The P1 value corresponds to the value that can be read from the pump display. See fig.

For further information about pump settings, see sections

10. Setting the pump

12. Pump settings and pump performance.

15.2 Curve conditions

The guidelines below apply to the performance curves on the following pages:

• Test liquid: airless water.

• The curves apply to a density of ρ = 983.2 kg/m temperature of +60 °C.

• All curves show average values and should not be used as guarantee curves. If a specific minimum performance is required, individual measurements must be made.

• The curves for speeds I, II and III are marked.

• The curves apply to a kinematic viscosity of  = 0.474 mm2/s (0.474 cSt).
