5.4 Cleaning
5.4.1 Cleaning and disinfecting the apparatus
Before cleaning, switch off apparatus and disconnect from mains
The apparatus housing can be cleaned with a cloth moistened with a liquid cleaning agent. To avoid
abrasion, the cloth must be moist. A surface-disinfecting agent may be used. Use cleaning agent
sparingly. Excess fluid could enter the apparatus causing damage.
5.4.2 Cleaning and sterilizing the Patient Module
The Patient Module can be autoclaved at a temperature of up to 134°C. Always autoclave the patient
module with the protection cover connected to avoid a damage of the diaphragm valves.
Before sterilizing the Patient Module, remove the bellows dome, bellows, CO
2
absorber and APL
valve. The patient module requires no further dismantling.
Autoclave the APL upper part and the APL membrane, as separate parts together with the patient
module.
The bellows dome cannot be autoclaved! It does not come in contact with patient gas. If soiled,
they can be cleaned with water and liquid cleaning agent. Do not use alcohol!
The silicon bellows and the CO2 absorber canister can also be autoclaved at 134°C. To enhance the
life of sealing materials, a temperature of 121°C i s recommended.

5.5.2 Battery Maintenance
Due to the self-discharging characteristics of this battery type, it is imperative that it is charged after
three months of storage (or when not in use). If not charged, a permanent loss of capacity may occur
as a result of sulfation.
The batteries used in the Modular
+
are of sealed lead acid construction. This battery type may be
subject to local regulations regarding disposal. At the end of the battery life, dispose of batteries in
accordance with the local regulations.
