4 Maintenance

4.1 General Maintenance Procedures

The performance and safety of the instrument will be kept if the following recommendations for care and
maintenance are observed:
• The instrument must go through at least one annual overhaul, which should be made by an
authorised workshop in order to guaranty proper service and repair as Interacoustics provides the
necessary circuit diagrams etc. to these repair shops.
To ensure that the reliability of the instrument is kept, it is recommended that the operator at short
•
intervals, for instance once a day, perform a test on a person with known data. This person could
be the operator him/herself.
After each examination of a patient, it should be ensured that there is no contamination on the
•
parts in connection with the patient. General precautions must be observed in order to avoid that
disease from one patient is conducted to others. If ear cushions or ear tips are contaminated, it is
strongly recommended to remove them from the transducer before they are cleaned. By frequent
cleaning water should be used, but by severe contamination it may be necessary to use a
disinfectant. The use of organic solvents and aromatic oils must be avoided.

4.2 Preventive Maintenance

Maintain the water level in the Aqua Stim external water tank. Use
the tap water available in your clinic is of poor quality. This will prevent bacterial and algae growth and to
prevent deposit of minerals on critical internal components.
When the Aqua Stim is not use, the hose should be coiled using the hose management tape.
Weekly
Clean the external water tank using soapy water and rinse with fresh water weekly. The external tank
has a pickup filter in the line connected to the white (Inlet) connector.
Monthly
Check the pickup filter in the external water tank and the in-line filter once a month for debris. The pickup
filter can be rinsed out and used again if the contamination is removed. Replacement pickup filters and
in-line filters are available from Interacoustics.
Annually
Calibration of the irrigation temperatures should be performed on an annual basis by Interacoustics (or
sooner if the operator suspects any change in performance). Please refer to the Error! Reference
source not found. for instructions on draining the water prior to shipment.
4.3 Cleaning Procedure to Reduce Bio-film Build-up inside the AquaStim™
Caloric Irrigator
• With a pH strip measure and document the pH of water from the irrigator taken during cool
irrigation before the cleaning solution is introduced.
• Add 1/4cup (60ml) of household bleach to a full Irrigator external tank
Power on the irrigator and select a cool irrigation cycle.
•
• Perform three consecutive cool caloric irrigations into a irrigator catch basin or larger container.
Carefully pour this bleach water into sink after each irrigation.
This completes the sanitation process, now the irrigator must be returned to a clinically usable
•
condition.
Drain the water from the irrigator as described in the User's manual
•
• Empty of water and scrub the external tank in a sink with dish soap in warm water. Rinse
external tank with warm water.
