maintenance.
Breathing system maintenance
Replace any parts that are visibly cracked, chipped, distorted, or worn
when cleaning the breathing system.
Minimum Frequency Maintenance
Daily • Clean the external surfaces.
• Perform 21% O2 calibration.
• Check the condenser reservoir (if equipped). Drain if
needed.
• Zero the flow sensors.
Two weeks Drain the vaporizers and discard the agent. This is not
necessary for the Tec 6 series vaporizers.
Monthly • Perform 100% O2 calibration.
• Lubricate all cylinder supply tee handle threads with
Krytox or a lubricant approved for use with 100% O2.
During cleaning and

necessary.
Annually Replace the external o-rings on the vaporizer ports.
As necessary • Install new cylinder gaskets on cylinder yokes.
• Empty the water reservoir and replace the absorbent in
the canister.
• Empty the overflow trap on the optional suction
regulator (if equipped).
• Replace the circuit O2 cell (under typical use the cell
meets specifications for 1 year).
• Replace the disposable (plastic) flow sensors (under
typical use the non-offset flow sensors meet
specifications for a minimum of three months and the
offset flow sensors meet specifications for a minimum
of six months).
• Replace the autoclavable (metal) flow sensors (under
typical use the sensors meet specifications for a
minimum of one year).

scavenging only).
