9.4 Maintaining your pump
9.4.1 Cleaning your pump
The best time to clean your pump is when you change the
cartridge. Use a soft cloth to clean the outside of the pump. If
necessary, use a clean cotton cloth dampened with alcohol
(70% Isopropanol or 50% Propanol), ensuring that no water
enters the pump. If this is not successful, contact your local
pump support (see inside back cover) for more information.
w WARNING
Always remove the cartridge and adapter and put your pump
in STOP mode while cleaning. Avoid pressing the keys of your
pump during cleaning, as this may accidentally change your
settings. Do not use solvents, strong detergents, bleaching
agents, scouring pads or sharp instruments for cleaning, as
they may damage the pump.
9.4.2 Batteries
It is important to change your battery regularly and to keep
sucient spare batteries available. The lifetime of any battery is
aected by how you use your pump, your personal settings,
delivery rates, temperature, and other factors. See Appendix A:
Technical Data, page151 for recommended batteries and their
respective lifetimes. See chapter2.1, page14 for instructions on
how to change the battery.
9.4.3 Battery cover
To ensure your pump remains watertight, replace the battery
cover when it looks used or dirty and at least every 3 months.
