Maintenance; After Each Procedure; Water Bottle Cleaning; Cleaning - Pentax EPK-1000 Owner's Manual

5. MAINTENANCE

5-1 AFTER EACH PROCEDURE

1. Turn OFF the power switch.
NOTE
-Some peripheral devices may have to be turned OFF
BEFORE the EPK-1000 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.
2. Disconnect the power plug, endoscope and water bottle .
NOTE
-Always turn OFF the processor BEFORE disconnecting
the endoscope.
3. Wipe all surfaces with gauze slightly dampened with alcohol.
NOTE
-NEVER allow liquids to be splashed on the EPK-1000.
Be sure connector interfaces and ventilation ports are not
allowed to become wet. To avoid processor damage, do NOT
allow harsh chemicals or cleaning agents to contact the front
panel membrane. Wipe with alcohol only.

5-2 WATER BOTTLE CLEANING

NOTE -Be careful when 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. Immediately after use, the entire water bottle assembly
(bottle, cap assembly and tubing) should be washed with
fresh detergent solution and dampened gauze or scrub brush.
Complete immersion in an 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 set to 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 at least 5 minutes.
3. After washing with the cleaning solution, all surface areas of
the water bottle assembly should be thoroughly rinsed and
dried. Use gauze or lint-free cloth to wipe dry most surfaces.
Compressed air and 70% alcohol may be used to facilitate
drying of hard to reach areas.
