CAUTION
z It is necessary to wait at least 5 seconds after setting the control dial to the 0 position
before opening the vaporizer. This allows the pressure to balance and prevents fresh
gas and anesthetic agent vapor from escaping out of the vaporizer.
2. Unscrew the filler cap slowly, so that any pressure in the vaporizer can escape slowly.
3. Check if the names of anesthetic agent and color mark on the vaporizer and the anesthetic
agent bottle correspond. If the correct agent is being used, unscrew the cap from the
anesthetic agent bottle. Pour anesthetic agent slowly into the filler receiver.
CAUTION
z Take care not to spill anesthetic agent. Inhaling anesthetic agent vapor endangers
health.
