11.1 MAINTENANCE CHECKS
As with any precision instrument, periodic inspection of the unit on an annual basis is
recommended, or on a more frequent basis if conditions require.
It is recommended that the following inspection be conducted on at least an annual basis and
recorded on the following page. Prior to recording, a copy of the page should be made so that
future inspection results can be recorded.
1. Visually inspect the line cord (mains lead) that is used to provide power to your CO
2
EFFICIENT
ENDOSCOPIC INSUFFLATOR. If it is worn, frayed or damaged, replace it immediately with
an equivalent IEC 60601-1 Rated (Medical Grade) line cord (mains lead) possessing a grounded
IEC-320 plug.
Warning: Do not use or replace with a commercially rated line cord (mains
lead).
2. Visually inspect the high-pressure hose between the CO
2
supply source and the rear panel of the
CO
2
EFFICIENT ENDOSCOPIC INSUFFLATOR. If it is worn, frayed, kinked or damaged, call
US Endoscopy immediately to obtain a replacement. Confirm hose is firmly attached to unit and
a “D” or “E” sized medical grade CO
2
tank.
3. Verify that the power rocker switch on the front panel is seated properly, undamaged, exhibits no
evidence of fluid/dirt infiltration. Plug in the line cord (mains lead), ensure the power switch is
on the “
I
” position and check if unit’s front display lights up.
4. Connect the device to a CO
2
supply source and attach a CO
2
EFFICIENT ENDOSCOPIC
INSUFFLATOR compatible tubing set to the outlet port on the front panel. Switch unit to Free
Flow mode using front panel rocker switch. Open CO
2
tank. Confirm CO
2
gas supply gauge on
front panel illuminates fully. When testing with the disposable water bottle tubing set, place the
capped end of the tubing set into a sterile water bottle that is 1/2 filled. Place the free end (the
end that normally connects to the endoscope) in a cup of sterile water. When testing with a
710304 (aka 6601) Tubing Set, place the free end (the end that normally connects to a reusable
CO
2
water bottle or Pentax adapter) into a cup of sterile water. Power on the CO
2
EFFICIENT
ENDOSCOPIC INSUFFLATOR.
a. Verify the unit insufflates CO
2
by pressing the FLOW STOP/RUN button. The green
lamp will illuminate. CO
2
will begin to exit the tubing set causing the water to bubble.
b. Switch flow mode to Managed Flow mode on the front panel and confirm CO
2
exits the
tubing set and causes the water to bubble. It will bubble with less intensity than it does
in Free Flow mode .
5. Turn unit off. Unplug Tubing Set and visually inspect the metal gas outlet connection on the
front panel for damage or fluid invasion.
6. Using an Electrical Safety Analyzer designed for measuring leakage current for medical
equipment (e.g. Fluke, Dynatech Nevada, Biotech, etc.), measure the earth leakage current.
Verify that this is less than 300 microamperes for the Class 1, Type B rating, as indicated on the
rear panel of the CO
2
EFFICIENT ENDOSCOPIC INSUFFLATOR. At conclusion of testing,
power off unit, shut-off CO
2
supply and unplug unit.
i. If you are unable to perform this inspection, the CO
2
EFFICIENT ENDOSCOPIC
INSUFFLATOR can be sent to US Endoscopy.
