6.5 Radio communication

The radio part of this product is a class 1 device and can be used

anywhere in the EU member states without restrictions.

Intended use

This pump incorporates a radio for remote control.

The pump can communicate with Grundfos GO and with other

MAGNA3 pumps of the same type via the built-in radio.

6.6 Insulating shells

Insulating shells are available for single-head pumps only.

Reduce the heat loss by insulating the pump housing and the

pipes. See figures 23 and 14.

• Insulating shells for pumps in heating systems are supplied

with the pump.

• Insulating shells for pumps in air-conditioning and cooling

systems, down to -10 °C, must be ordered separately. See

section 11.7 Insulating kits for air-conditioning and cooling

systems.

The fitting of insulating shells increases the pump dimensions.

Fig. 23 Insulating shells

Pumps for heating systems are factory-fitted with insulating

shells. Remove the insulating shells before installing the pump.

6.7 Non-return valve

If a non-return valve is fitted in the pipe system, make sure that

the set minimum outlet pressure of the pump is always higher

than the closing pressure of the valve. See fig. 24. This is

especially important in proportional-pressure control mode with

reduced head at low flow.
