4. Installation
4.1 General notes
PrimAX is only intended for installation indoors. The pumps must be mounted voltage-free
so that no energy can be transferred from the pipes to the pump casing. The pumps can be
installed directly in the pipe, provided the pipes are designed for the weight of the pump.
Installation is only possible after completion of all welding and soldering work on the system.
Avoid drops of water on the pump motor, especially the frequency converter.
4.2 Flushing heating equipment (for extended pump)
To avoid unwanted interruptions to operations and non-running of the pump after longer
periods of inactivity, we recommend thoroughly flushing out the equipment following the
new installation or adaptation of heating and refilling.The equipment must correspond with the
latest technology. (Placement of expansion vessel or safety flow).
4.3 Installation
Install only after completion of all welding or soldering work on the equipment. Water drops
should be avoided on the pump motor, especially on the electronics. The pump casing should
be installed voltage-free in the equipment.
4.4. Non-return valve
If a non-return valve is fitted, the pump must be adjusted, 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).
4.5 Flow direction
The arrow on the pump casing indicates the flow direction.
