The adapter connects the cartridge to the infusion set, and also
keeps the cartridge compartment watertight with two seals, one
inside and one outside the adapter. It holds the cartridge in place
and prevents the entry of air bubbles. The two small vents on the
adapter allow air pressure to be equalized inside and outside the
cartridge compartment. The adapter will not work properly if the
vents are blocked or dirty, or if the seals are missing.
Note It is essential to change the adapter at least every two
months. You must also change the adapter if the seals
become worn, are lost, or if the vents are blocked.
1.4.3 Battery
Your pump requires one AA 1.5 V battery in order to function. Use
AA high-quality alkaline LR6 or lithium FR6 batteries that have a
minimum capacity of 2500 mAh. Do not use carbon zinc or nickel
cadmium (NiCd) batteries.
If you prefer, you can use rechargeable batteries – in this case,
use AA 1.2 V NiMH HR6 batteries with a minimum capacity of
2500 mAh. Always use a battery charger recommended by the
battery manufacturer. See Appendix A Technical Data p. 176.
