5.1 Important dimensions

Physical dimensions and connections for the
pump unit are described in Data sheet,
appendix 1.

5.2 Cleanliness

It is very important that the tubes and pipes are
completely clean: no dirt, chips or burrs are
allowed. Flush all piping before connecting the
high pressure pump to ensure the system is
clean. Internal surfaces of the piping must not be
corroded. If dirt or rust is not removed, the pump
and the valves can be damaged and in the worst
case damaged beyond repair!

5.3 Fluid temperature

Before start-up, the fluid and pump housing
temperature must be above the minimum
start-up temperature, see Data sheet,
appendix 1.

5.4 Electrical data

Check voltage, current frequency and rated
power on the electric motor and VFD setting
name plate on both the motor and the VFD.

5.5 Local regulations

Commissioning must always be done in
accordance with valid regulations and local
standards.
