Recommended Action
1. Examine the suction tubing along its
entire length for a blockage.
2. Squeeze the blocked area to loosen it.
3. Immerse the handpiece tip in sterile
irrigation fluid briefly. This may clear
the blockage.
Replace the suction canister.
1. Remove any unused suction canister
"elbow" connectors.
2. Reseat all connections.
Close any open ports on the suction
canister.
Refer to the canister manufacturer's
instructions for connecting the canister.
1. Disconnect the contamination guard
fitting from the suction canister
tubing. If you feel no suction at the
end of the contamination guard
fitting, the guard is blocked.
2. Replace the contamination guard.
Remove the contamination guard and put
a finger in the suction system port. If you
feel no suction, call Integra for assistance.
Check the Lap mode indicator.
• If Lap mode is off, in Run mode the
pinch valve should be open.
• If Lap mode is on, in Run mode the
pinch valve should be open only
when you activate vibration.
If these conditions do not exist, call
Integra for assistance.
Hold the handpiece at the nosecone.
Replace the handpiece.
Install the large o-ring in the proper
position on the handpiece.
Replace the nosecone.
