5. Starting up the product

5.1 Before startup

Do not start the pump until the system has been filled with liquid

and vented. Make sure that the required minimum inlet pressure

is available at the pump inlet. See section 10. Technical data.

When using the pump for the first time, the system must be

vented at the highest point. See section 5.3 Venting the system.

The pump is self-venting through the system.

5.2 Starting up the pump

5.3 Venting the system

Fig. 7 Venting the system

When the system has been filled with liquid and the minimum

inlet pressure is available at the pump inlet, do as follows:

1. If turned off, turn on the pump. See section 5.2 Starting up the

pump.

2. If the vent valve is installed in the system, open up the valve

manually. See fig. 7, 1A. If the pump housing has an air

separator installed (ALPHA1 L XX-XX A) and an automatic

vent has been fitted, the air escapes automatically. See fig. 7,

1B.

3. Set the pump to speed III. See fig. 7, 2.

4. Let the pump run for approximately 10 minutes. See fig. 7, 3.

Repeat step 1-3, if necessary.

5. Set the pump according to the recommendations. See section

7. Control functions.

TM06 9069 1617

In heating systems that often contain much air, we

recommend that you install pumps with pump

housing with air separator, that is ALPHA1 L XX-XX

A. The pump housing has an Rp 3/8 tapping for fitting

of an automatic air vent. The vent is not supplied with

the pump.

The pump must not run dry.

English (GB)

5.4 Venting the pump

Fig. 8 Venting the pump

Small airlocks trapped inside the pump may cause noise when

starting up the pump. However, because the pump is self-venting

through the system, the noise ceases over a period of time.

To speed up the venting process, do as follows:

1. Set the pump to speed III for approximately 10 minutes. How

fast the pump is vented depends on the system size and

design.

2. When you have vented the pump, that is when the noise has

ceased, set the pump according to the recommendations. See

section 7. Control functions.

6. Product introduction

6.1 Product description

ALPHA1 L model C is a complete range of circulator pumps.

See section 10. Technical data for further information.

6.1.1 Model type

These installation and operating instructions cover ALPHA1 L

model C. The model type is stated on the packaging.

6.2 Applications

The ALPHA1 L is designed for circulating liquids in all kinds of

heating applications. The pumps are suitable for the following

systems:

• Systems with constant or variable flows where it is desirable to

optimise the pump duty point.

• Systems with variable flow-pipe temperature.

ALPHA1 L is especially suitable for the following:

• Installation in existing systems where the differential pressure

of the pump is too high during periods of reduced flow

demand.

• Installation in new systems for automatic adjustment of the

performance to flow demands without the use of bypass

valves or similar expensive components.

High-efficiency ECM (Electronically Commutated Motor) pumps,

such as ALPHA1 L, must not be speed-controlled by an external

speed controller varying or pulsing the supply voltage.

The speed can be controlled by a low-voltage PWM (Pulse Width

Modulation) signal.

TM06 8575 1617

The pump must not run dry.

The pump is from factory set to radiator heating

mode.

6.3 Pumped liquids

In heating systems, the water must meet the requirements of

accepted standards on water quality in heating systems, for

example the German standard VDI 2035.

The pump is suitable for clean, thin, non-aggressive and

non-explosive liquids, not containing solid particles, fibres or

mineral oil. The pump must not be used for the transfer of

flammable liquids, such as diesel oil, petrol and similar liquids.

• Maximum water/propylene glycol mixture is 50 %

• Maximum 10 mm2/s viscosity

Note: The water/propylene glycol mixture reduces the

performance due to higher viscosity.

See section 10. Technical data for further information.

6.4 Identification

6.4.1 Nameplate

Fig. 9 Nameplate

CAUTION

Flammable material

Minor or moderate personal injury

- Do not use the pump for flammable liquids, such

as diesel oil and petrol.

WARNING

Biological hazard

Death or serious personal injury

- In domestic hot-water systems, the temperature of

the pumped liquid must always be above 50 °C

due to the risk of legionella.

WARNING

Biological hazard

Death or serious personal injury

- In domestic hot-water systems, the pump is

permanently connected to the mains water.

Therefore, do not connect the pump by a hose.

CAUTION

Corrosive substance

Minor or moderate personal injury

- Do not use the pump for aggressive liquids, such

as acids and seawater.
