Maintenance
Daily
Clean the external surfaces.
21% O2 calibration (O2 sensor in breathing system).
Biweekly Drain the vaporizers and discard the agent.
Monthly
100% O2 calibration (breathing system O2 sensor).
Clear water built up inside the waterstraps of CO2 module
and AG module.
During cleaning
and setup
Inspect the parts and O-rings for damage. Replace or repair
as necessary.
Annually
Replace the seal on the vaporizer manifold and that on the
breathing system port. Contact us for details.
CO2 module calibration.

As necessary
Before installing the cylinder, use a new cylinder gasket on
cylinder yoke.
Empty the water collection cup If there is water built up in it.

(Under typical use the sensor meets specifi cations for one
year.).
Replace the fl ow sensor if it is damaged.
Calibrate the fl ow sensor when any of the following occurs:
1) the fl ow sensor is changed; 2) the tidal volume set is not
consistent with that displayed when no leakage occurs;
3) there is a great difference between the tidal volume
measured and that displayed by the bellows scale when
fresh gas is very small.

NOTE
：
These schedules are the minimum frequency based on typical usage of 2000
