* If the ambient temperature is higher than the values stated, please contact Grundfos.
** It is very important that the pump operates with the required discharge pressure to ensure proper lubrication of the pump.
6. Preparation
Before installation, the following checks should be made:
• Check for transport damages
Make sure that the BMPX units have not been damaged
during transportation.
• Type of system
Check that the type designation corresponds to order. See
nameplates.

The motor and VFD voltage and frequency details given on the
nameplate should be compared with the actual electricity
supply available.
• X-Changer
Check that all nuts are tightened.
