Grundfos MAGNA3 D 32-80 180 97924451 [10/1656] Changing the control box position

English (GB)

3.7 Changing the control box position

The warning symbol on the clamp holding the pump

head and pump housing together indicates that there

is a risk of personal injury. See specific warnings

below.

CAUTION

Crushing of feet

Minor or moderate personal injury

- Do not drop the pump head when loosening the

clamp.

CAUTION

Pressurised system

Minor or moderate personal injury

- Pay special attention to any escaping vapour

when loosening the clamp.

Fit and tighten the screw that holds the clamp to 8

Nm ± 1 Nm. Do not apply more torque than specified

even though water is dripping from the clamp. The

condensed water is most likely coming from the drain

hole under the clamp.

Check the position of the clamp before you tighten

the clamp. Incorrect position of the clamp will cause

leakage from the pump and damage the hydraulic

parts in the pump head.

Step Action Illustration

Loosen the screw in the

clamp that holds the pump

head and pump housing

together.

If you loosen the screw too

much, the pump head will be

completely disconnected

from the pump housing.
