3.20.1 Instructions for re-using and disposal

3.20.1.1Re-use

Re-use or putting the pump out of service should only be undertaken after complete draining and cleaning of the internal parts.

Note! When doing so, observe adequate safety regulations and take environmental protection measures.

Liquids should be drained and following local safety regualtions the correct personal equipment should be used.

3.20.1.2Disposal

Disposal of the pump should only be done after it has been completely drained. Proceed according to local regulations.

Where applicable please disassemble the product and recycle the parts’ material.

3.21 Maintenance instructions

3.21.1 General

This chapter only describes operations that can be performed on-site for normal maintenance. For maintenance and repair requiring a workshop contact your distributor.

•Insufficient, wrong and/or irregular maintenance can lead to malfunctions in the pump, high repair costs and long-term inoperability. Therefore, you should carefully follow the guidelines given in this chapter.

During maintenance operations on the pump due to inspections, preventive maintenance or removal from the installation, always follow the prescribed procedures.

Non-compliance with these instructions or warnings may be dangerous for the user and/or seriously damage the pump/pump unit.

•Maintenance operations should be performed by qualified personnel only. Always wear the required safety clothing, providing protection against high temperatures and harmful and/or corrosive fluids. Make sure that the personnel read the entire instruction manual and, in particular, indicate those sections concerning the work at hand.

•SPX Process Equipment is not responsible for accidents and damage caused by non- compliance with the guidelines.

•Personnel who carry a cardiac pacemaker should not be allowed to work on a pump equipped

with magnetic coupling!. The magnetic field is sufficiently strong to affect the proper operation of a pacemaker, so keep a safe distance of at least 3 m.

•Do not come close (not less than 1 m) to the magnetic coupling with subjects equippid with magnetic data carrier such as cheque cards, computer disks, watches etc. to avoid damage

and/or loss of information.

3.21.2 Preparation

3.21.2.1Surroundings (on site)

Because certain parts have very small tolerances and/or are vulnerable, a clean work environment must be created during on site maintenance. Particularly remove metallic chips or any dirt which could be attracted by the components of the magnetic coupling.
