11.2 Maintenance Schedule
Minimum frequency Maintenance
During cleaning and setup Inspect the parts for damage. Replace as necessary.
Several times a day or as
necessary
Check the breathing hoses and water traps for water build-up. Empty
water build-up if there is.
Daily or as necessary Clean the external surfaces.
Calibrate the O2 sensor.
Check the filter water trap at the O2 gas supply inlet (drain the water
manually). If there is water build-up, press the spring pin upward at the
bottom of the water trap to drain the water (if water is drained in
ventilation status, water may splash. It is recommended to drain the
water in gas cut-off status and use a container for drainage to prevent
water from splashing onto the electrical plug underneath). After water
drainage is completed, the spring pin returns to the original position
automatically. If cracks or leaks are found on the water trap, contact the
service personnel.
Check the filter water trap at the Air gas supply inlet (drain the water
manually). If there is water build-up, rotate the black handle at the
bottom of the filer water trap gently (clockwise or counterclockwise).
The water can be drained when the handle is rotated at the almost
vertical position (if water is drained in ventilation status, water may
splash. It is recommended to drain the water in gas cut-off status and
use a container for drainage to prevent water from splashing onto the
electrical plug underneath). After water drainage is completed, return
the black handle at the bottom to the original position to prevent
leakage (rotate to the horizontal level clockwise or counterclockwise).
If cracks or leaks are found on the water trap or if the handle at the
bottom cannot be rotated or has cracks, contact the service personnel.
Before each use or after
continuous use of two
weeks
Perform system self-test. Check the breathing system resistance and
leakage.
Check every half a year
and replace every three
years
Check the charging and discharging of the lithium battery every half a
year and replace the lithium battery every three years.
