4-3. WATER BOTTLE ASSEMBLY
Each water bottle assembly should be cleaned and sterilized at least on a daily basis or more frequently depending
upon the patient and/or type of endoscopic procedure. As with all endoscopic accessories, prior to sterilization,
water bottle assemblies must be scrupulously cleaned. Failure to do so could result in incomplete or ineffective
sterilization.
I. Cleaning of Water Bottle
1) After use, the entire bottle assembly (water container, cap and tubing) should be washed with clean
running water and a dampened gauze or scrub brush.
2) Ultrasonic cleaning of the entire water bottle assembly is then recommended to access difficult to
reach areas, provided the operating frequency is 44 kHz ± 6% for a period of at least 5 minutes.
3) After washing with a cleaning solution, all surfaces of the water bottle assembly should be thoroughly
rinsed with clean water and dried. Gauze or cloth can be used to wipe dry most surfaces. Compressed
air and 70-90% ethyl or isopropyl alcohol should be used to facilitate drying of hard to reach areas.
II. Sterilization of Water Bottle
Before any attempt is made to sterilize the water bottle assembly, the complete cleaning procedure described
above must have been completed. Failure to scrupulously clean the water bottle prior to the sterilizing process,
could result in incomplete or ineffective sterilization.
WARNING:
The addition of defoaming agents to the water supply is NOT recommended. Due to their nature, these
silicone based agents cling tenaciously to surfaces. Unless they are rinsed very thoroughly, a “barrier”
could be created which could reduce the effectiveness of the disinfection/sterilization process. Addition-
ally, repeated use of such defoamers could eventually lead to residual silicone build up resulting in
equipment malfunction such as clogged air and/or water channels.
NOTE:
Take care in handling the water bottle. DO NOT carry the bottle by the A/W Connector or the hose. When
the bottle cap has been removed from the bottle, be careful in handling the water feeding stem.

CAUTION:
To avoid disconnection and/or bursting of the internal tubing, always set the lever to the Air/Water posi-
tion (upright) and use less than 165 KPa (24 psi) air pressure during forcep air drying.
CAUTION:
Use only the type of packaging material and package configuration as recommended by the manufac-
turer of the sterilizer. Use appropriate heat process indicators and/or biological monitors as recom-
mended by the manufacturer of the sterilizer.
NOTE:
The following sterilization parameters are only valid with sterilization equipment that is properly main-
tained and calibrated.
