As a final step, check the both external pickup and in-line filters for any visual debris, if no debris seen
you can continue using the filters for the normal use. If you see any debris, the filter to be replaced
appropriately. Refer section 4. 8 for filter replacement procedure.

4.5 Quarterly

Verification of the irrigation flow rate can be performed by the clinician with the use of a graduated
cylinder of 500ml capacity with 5ml marks. The clinician should perform a cool irrigation and measure the
output water amount. If the volume of water is in excess of 265ml, then contact Interacoustics for irrigator
calibration.
If the volume is less than 235ml, then disconnect the water filter assembly from the handle and connect
the handle's red tube directly to the irrigator bypassing the water filter assembly entirely. Perform a cool
irrigation and measure the output water amount. If the volume is 250ml, then follow the instructions in 4.
9 Replacing the water filters section. If the volume is still low, then contact Interacoustics for further
troubleshooting.

4.6 Annually

Replace the cone filter /in-line filter in the internal water tube system every year as a part of maintenance.
And, clean out or replace the pick-up filter in the external water tank. The irrigator system is to be cleaned
with acetic acid every year as a part of demineralization procedure (mineral deposit removal).
Laboratory verification of the irrigation temperatures and flow rates should be performed annually by a
trained service technician. If the irrigator fails temperature or flow rate verification, contact Interacoustics
to send back the irrigator for factory calibration. Note: the irrigator must be drained of water prior to
shipment.

4.7 Annual cleaning procedure

4.7.1 Tools needed

Measuring container, pH strips, 5% acetic acid, graduated cylinder and two in-line filter cones, protective
goggles, rubber gloves, and protective apron.
4.7.2 Prepare vinegar & water solution (mineral deposit removal)
Clean the external water tank with dish soap and warm water before you start the demineralization
procedure.
Fill the external water tank with 2 liters of water and add 8tsp (40ml) 5% acetic acid. Stir the solution
gently. The acetic acid solution is used to remove mineral deposits which is detected by looking at the
blue tube and seeing the blue tube opaque or filled with small particulate. Start cool irrigation cycle and
this will draw and circulate the solution into the internal tank. Wait until the cycle is completed which will
take approximately 10 minutes. After 10 minutes of holding the solution inside the system, drain the
irrigator appropriately. Discard the excess solution carefully in the sink from the external water tank.
Clean the external water tank again with dish soap and warm water. Also, rinse external water tank with
distilled water to remove vinegar residues. Refill the external water tank with 600 mL of distilled water and
document the water pH in the external tank. Run three cool irrigation cycles to rinse off the chlorine
residues from the system. At the end of 3
level of irrigated water doesn't match with the water pH in the external tank, repeat the cool irrigation
cycle until the target water pH is achieved.
