3.4 Non-return valve

If a non-return valve is fitted, the pump must be adjusted (see 7.2),
so that the discharge pressure of the pump exceeds the closing
pressure of the valve at all times.
This must be adhered to in particular for the proportional pressure
control (reduced delivery height for decreasing delivery flow).

3.5 Protection from the effects of frost

Where there is a risk of frost during downtime
periods, measures required to avoid frost
damage must be taken.

3.6 Heat insulation

Heat is lost via the pump casing and pipes.
These heat losses should be limited
to a minimum.
Heat losses can be reduced by insulating the pump casing
and pipes.
For ModulA RED, heat insulation shells are included in the delivery.
Heat insulation shells can only be supplied for single pumps.
- Never cover the frequency converter or the
control panel with insulation.
➁ Keep the drainage outlet at the motor free.

3.7 Flow direction

The arrow on the pump casing indicates the flow direction.
