Wipe all surfaces with gauze slightly moistened with alcohol.

NOTE

Never allow liquids to be splashed onto the EK-700.
Ensure connector interfaces and ventilation ports do not
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.

6-2-1 Cleaning

1. After use, the entire water bottle assembly (bottle, cap
assembly and tubing) should be washed with clean water and
moistened gauze or scrubbing brush. Enzymatic detergent
solution should be used for soiled items.
Detergent may be applied to internal surfaces of the water
bottle 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.

30

MAINTENANCE

2. Ultrasonic cleaning of the entire water bottle assembly is
recommended to access difficult to reach areas. Use an
operating frequency of 40 kHz or higher for a period 5-10
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.

6-2-2 Sterilization

Before any attempt has been made to sterilize the water bottle
assembly, ensure the cleaning process above has been completed.

6-2-2-1 Steam sterilization

NOTE

EPK-700 standard water bottle assembly is model OS-H2
and is steam autoclavable. DO NOT confuse the OS-H2
steam autoclavable water bottle with its non-autoclavable
predecessor that had been supplied as a standard
accessory with other Pentax products.

The OS-H2 water bottle assembly can be easily identified by the
black Air/Water hose, off-white coloured plastic cap (NOT
transparent) and the clear plastic bottle.

1. The OS-H2 water bottle assembly has been designed to
withstand high pressure steam sterilization procedures. Use
the parameters below:

TEMP: 121 °C (250 °F)
PRESSURE: 101.3 kPa (1 atmosphere)
TIME: 90 minutes

2. During steam sterilization, ensure the cap assembly has been
removed from the bottle and the drain lever set to the upright
(A/W) position.

55 °C (131 °F).

6-2-3 Care during storage

Prior to storage it is important to ensure that no residual water is left
inside the water bottle assembly. Thoroughly dry all surfaces to
reduce the potential for bacteria colonization during storage.
Compressed air and 70 % alcohol should be used to facilitate
drying.

6-3 Storage

Do not store the unit in direct sunlight or where temperature and
humidity are high.

Do not store the unit where it can be exposed to liquids.

For long term storage, take precautions to reduce dust build up
within the EPK-700.

6-4 Changing the lamp

Check the lamp life hour meter on the rear panel frequently. A lamp
with 200 hours or more should be replaced before beginning a
procedure
