soiled.

4.4 Weekly

Internal & external water tube system, external water tank, pickup filter in the external water tank and in-
line filter shall be disinfected every week.
The user shall choose Isopropyl alcohol (70-80% v/v) or chlorine solution to disinfect the system. The
instructions for disinfection procedure are discussed below.
Disinfection with Isopropyl alcohol (70-80% v/v):
Before starting the disinfection procedure, the user should drain the irrigator by pressing the two buttons
on the right side of the irrigator display. Clean the external water tank with dish soap and warm water
before you start the disinfection procedure. Then fill the external water tank with 600 ml of Isopropyl
alcohol (70-80% v/v). Run one complete cycle of cool irrigation. Then 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 alcohol residues. Refill the external water tank with 600 ml of distilled water and
run couple of cool irrigation cycles to rinse off the alcohol residues from the system.
As a final step, check both the 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.
Disinfection with Chlorine solution:
Clean the external water tank with dish soap and warm water before you start the disinfection procedure.
Then fill the external water tank with 60 ml of chlorine solution make up the volume with water to 2 L. Run
three consecutive cool irrigation cycles. Drain the irrigator appropriately. Discard the excess solution
