2.3 Commissioning

Commissioning of BMSX booster systems must be carried out by
certified Grundfos employees to ensure long and trouble-free
operation.
If this requirement is not met, the warranty will be
Note
invalidated.
Commissioning includes onsite training of the people who will be
responsible for maintaining and monitoring the system.

2.4 Pumped liquids

Thin, non-explosive liquids, not containing solid particles or
fibres. The liquid must not chemically attack the pump materials.
In case of doubt, contact Grundfos.
The pumps must never operate with water/liquid containing
substances which would remove the surface tension, e.g. soap.
If this type of detergent is used to clean the system, the water/
liquid must be led around the pumps via a bypass.
Warning
The pumps must not be used for pumping
flammable or combustible liquids such as diesel
oil, petrol or similar liquids.

system or pump(s) under all conditions. The pump and motor
must be installed at the same level.
The foundation must be strong enough to support the weight of
the both units.
