Start and run the pump for a few minutes. Check that the pump operates normally.
Open the inlet isolation valve.
Reinstall the canopy panel(s).
If you intend to apply the pump on humid applications, it is
recommended that the unit is allowed to achieve optimal running
temperature before it effectively put in operation. This can be done
by running the unit against a closed suction line for 30 minutes.
Starting
Procedure
Check oil level and oil condition.
Switch on the voltage.
To avoid excessive energy consumption and damage to the

Regularly check the oil level and the oil condition. The oil level should be in the middle
of the oil sight glass. Top up, if necessary, with correct type of oil.
It is recommended to use genuine lubricants.
