High priority alarm
Air-in-line alarm
Occurrence
Cause
Action
• LCD: The Air-in-line alarm
display flashes red.
• Operation indicator: Flashes
red.
• Buzzer: Activates.
• Pump: Stops.
• The drug solution has run out.
• If you wish to continue the infusion, replace the drug
solution and start infusion following usual procedure.
(See page 29.)
• To end infusion, close the manual roller clamp, open
the door, release the tube clamp and remove the set.
(See page 42.)
• There is air in the infusion set.
• Detach the infusion set and tap the tube to chase the air
up into the drip chamber.
• The infusion set is not installed
correctly.
• The door was closed without
the infusion set installed.
• Re-set the infusion set correctly. (See page 30.)
• The air-in-line detector is dirty.
• If the air-in-line detector is dirty, wipe it clean with a
cotton swab or damp cloth (not wet). (See page 86.)
• An infusion set other than
those specified is being used.
• If an infusion set other than the ones specified is
being used, replace it with the dedicated infusion set.
(See page 19.)
• The line upstream of the
infusion pump is occluded.
• See page 94 “Upper Occlusion alarm”.
Note
• The Air-in-line alarm may occur due to an upper occlusion instead of the Upper Occlusion alarm. In this case, see page 94
“Upper Occlusion alarm”.
• If you wish to change the detection sensitivity, see page 55 “Air-in-line Alarm Sensitivity Select Function”.
Caution
• Allow drug solution to reach room temperature before use. If used when cold, air bubbles are produced due to evaporation
of dissolved air and this causes Air-in-line alarms to occur frequently.
