The GRUNDFOS ALPHA2 L circulator pump is designed for the

circulation of water in heating systems.

Install the GRUNDFOS ALPHA2 L in

• underfloor heating systems

• one-pipe systems

• two-pipe systems.

GRUNDFOS ALPHA2 L incorporates a permanent-magnet motor and

differential-pressure control enabling continuous adjustment of the pump

performance to the actual system requirements.

GRUNDFOS ALPHA2 L has a user-friendly front-mounted control panel.

1. Fit the two gaskets supplied when the pump is mounted in the pipe.

See fig. 3, pos. A.

2. Install the pump with the motor shaft horizontal. See fig. 3, pos. B.

Control box positions

The control box can be rotated in steps of 90 °.

Possible/permissible positions and the procedure of changing the position

of the control box are illustrated in fig. 4, pos. A.

Procedure:

1. Slacken and remove the four hexagon-socket head screws holding the

pump head with a tee key (M4).

2. Turn the pump head to the desired position.

3. Insert and cross-tighten the screws.

Insulation of pump housing

The heat loss from the pump and pipework can be reduced by insulating

the pump housing and the pipe. See fig. 5.
