u
Turn the flowmeter knob fully open and observe as the float ascends and descends

u
Inspect lines, connectors and accessories for wear prior to use.
u
Perform a Leak Test (shown on bottom).
u
Use a damp cloth to clean.
u
DO NOT use alcohol.
u

Dilute Chlorhexidine or similar cleaning and disinfecting agent can be used.
ROUTINE MAINTENANCE
BEFORE EACH USE, “LEAK TEST” THE MACHINE,
AND ALSO ENSURE THAT THE WASTE GASES HAVE
A CLEAR WAY THROUGH YOUR EVACUATION SYSTEM.

Close the pop-off valve and create a tight seal of the patient circuit
with your hand.
Push the oxygen flush button, or turn on oxygen flow meter, until
the bag is fully distended and/or manometer reads 30-40 cm of H

O
pressure.
Re-open the pop-off valve to your standard setting.
Squeeze the bag (with your hand still over the patient circuit) to ensure
the gases have a clear way out through your scavenging system.
Release the oxygen flush button and/or ensure the oxygen flowmeter
is off; float is at the bottom of the tube. Observe the manometer (or the
bag if your machine does not have a manometer) for 20-30 seconds.
The manometer needle should remain steady. If the manometer needle
drops, the bag deflates, or if you hear a hissing sound, you have a leak.
Check hoses, bag, vaporizer inlet and outlet, any fittings or seals at the
top and/or bottom of your CO

absorbent container for leaks (a soapy
water solution can be used for leak test). When the pressure remains
constant, with the oxygen turned off, your machine can be considered
leak-free on the low-pressure side.
