Additional Information
Air Sensors
• Do not drop air, level, or flow sensors as shock may damage the sensor.
• Do not sterilize air, level, or flow sensors as sterilization may damage the sensor.
Level Sensors
• Do not drop air, level, or flow sensors as shock may damage the sensor.
• Do not sterilize air, level, or flow sensors as sterilization may damage the sensor.
• Use only Sarns™ Level Sensor II Gel. The use of any other gel, couplant, or
lubricant may cause damage to the level sensor lens.
Flow Sensors
• Do not drop air, level, or flow sensors as shock may damage the sensor.
• Do not sterilize air, level, or flow sensors as sterilization may damage the sensor.
• Ultrasonic Sensor Gel contains polyoxalene, silicon dioxide, and triethanolamin.
Causes eye irritation. Immediately flush eyes with large amounts of water. Get
immediate medical attention.
Gas System
• The oxygen and air supplies must both be connected (or disconnected) to
prevent unequal pressure from damaging the gas blender.
Centrifugal Pumping
• Do not operate the centrifugal pump when unprimed as operating the pump in a
"dry" state may damage the internal seal.
• Monitor the centrifugal pump and replace it if there are fluid leaks, noisy
operation, or blood in the rear chamber. Blood in the rear chamber will damage
the pump bearings and cause the pump to eventually fail.
• During Pulse mode pumping, because of variations in flow, the flow rate
displayed is a mean value.
• When located on the inlet side of the centrifugal pump, automatic ball-type
shutoff valves (used to prevent gas emboli from entering the arterial line),
may seat inadvertently and stop flow.* Follow manufacturer's instructions for
placement of valves.
• Do not sterilize the centrifugal drive motor, as sterilization may damage the motor.
