Dismantlement
To dismantle the pump or before performing pump maintenance, proceed as follows:
• Make sure the pump is electrically deactivated (both poles) by disconnecting the conductors from the power
supply using the omnipolar switch which must have a minimum distance of 3mm between its contacts (Fig.3).
•
Relieve the pressure in the pump head and the discharge tube in the most adequate way possible (be very
careful during this operation).
• Drain the liquid present in the pump head by disassembling and reassembling the pump head using the four
fixing screws, tightening torque 180÷200 N*cm (Appendix 1).
Please pay particolar attention to this last point and we recommend the user to consult the enclosed drawings and
chapter “RISKS” before starting any operations.
