6. MAINTENANCE

6-1 AFTER EACH PROCEDURE

NOTE
-Some peripheral devices may have to be turned off
BEFORE the EPK-700 to avoid compromising their operation.
Refer to the operating instructions supplied with all the
components of the video endoscopy system to establish the right
order in which each component should be turned off in due course.
Disconnect the endoscope and water bottle .
●
NOTE
-Always turn off the processor BEFORE disconnecting
the endoscope.
Wipe all surfaces with gauze slightly dampened with alcohol.
-Never allow liquids to be splashed on the EK-700. Be
NOTE
sure connector interfaces and ventilation ports are not allowed
to become wet.

6-2 WATER BOTTLE CLEANING

NOTE -Take care in handling the water bottle. DO NOT carry
the water bottle by the Air/Water Connector or Air/Water hose.
When the cap assembly has been separated from the bottle, be
careful in handling the water feeding stem.
Water bottles should be sterilized at least on a daily basis.
Like all endoscopic accessories, the water bottle assembly must
be thoroughly cleaned. Failure to do so could result in
incomplete or ineffective sterilization.

(1) CLEANING

1. After use, the entire water bottle assembly (bottle, cap
assembly and tubing) should be washed with clean water and
dampened gauze or scrub brush. Enzymatic detergent
solution should be used for soiled items.
● Internal surfaces of the water bottle assembly may be
exposed to the detergent by injecting the detergent into the
air pipe stem (opposite the A/W-Drain lever on the water
bottle cap) using a syringe. The A/W-Drain lever should be
in the A/W position to ensure contact with all internal tubes.
2. Ultrasonic cleaning of the entire water bottle assembly is
recommended to access difficult to reach areas. Use an
operating frequency of 44 kHz ± 6% for a period 5 minutes.
3. After washing with the cleaning solution, all surfaces of the
water bottle assembly should be thoroughly rinsed and dried.
Use gauze or cloth to wipe dry most surfaces. Compressed
air and 70% alcohol should be used to facilitate drying of
hard to reach areas.
