w V B
Attention consult accompanying documents: Prior to using this pump, carefully read the Operating Precautions described in the Directions for Use (DFU).
This pump contains static-sensitive components. Observe strict precautions for the protection of static sensitive components when attempting to repair and service the pump.
An explosion hazard exists if the pump is used in the presence of flammable anaesthetics. Exercise care to locate the pump away from any such hazardous sources.
Dangerous Voltage. An electrical shock hazard exists if the casing of the pump is opened or removed. Refer all servicing to qualified service personnel.
M This pump is protected against the effects of high energy radio frequency emissions and is designed to be fail safe if extremely high levels of interference are encountered. Should false alarm conditions be encountered, either remove the source of the interference or regulate the infusion by another appropriate means.
If the pump is dropped, subjected to excessive moisture, humidity or high temperature, or otherwise suspected to have been damaged, remove it from service for inspection by qualified service personnel.
When connected to an external power source, a three-wire (Live, Neutral, Earth) supply must be used. If the integrity of the external protective conductor in the installation or its arrangement is in doubt, the pump should be operated from the battery.

Preventative Maintenance
Preventative Maintenance
To ensure the pump remains in good operating condition, routine and preventative maintenance inspections are required. Routine maintenance inspections should be performed by hospital/facility before each use, see Directions For Use for details.
Preventative maintenance inspections should be performed at least every year.
For the preventative maintenance inspection the following should be performed:
•Full visual inspection of the pump, internal and external
•Fitting of all updates required
•Battery test and/or replacement
•Clean the pump
•Performance Verification Procedures
Following all spare part replacement and repair activities, testing must be performed in accordance with the Performance Verification Procedure (PVP). Additional testing and calibration may be required after certain repairs are completed, see table in Chapter 6 ‘Corrective Maintenance’ for more information.
Visual Inspection
Open the pump, as per Chapter 6 ‘Corrective Maintenance’ and visually inspect the interior of the pump. Visually inspect the exterior of the pump checking the following:
•Labels should be replaced as required if not flat, legible or fully adhered.
•Check Keypad for any sign of wear and replace as required.
•Case components must be checked for damage and replaced if necessary.
•Check the pole clamp is not damaged and that it functions correctly.
•Inspect the AC power supply plug and cable for damage.
•The case should be clean and free from IV solution residue, especially near moving parts.
•Check for dried solution deposits on accessible areas of pumping mechanism.

Cleaning the Flow Sensor: -
Before the transfer of the flow sensor to a new infusion set and periodically during use, clean the flow sensor by wiping over with a lint-free cloth lightly dampened with warm water and a standard disinfectant / detergent solution. Ensure the connector does not get wet. Dry flow sensor before use.
To aid cleaning of flow sensors which have been heavily soiled, contaminated or if the handle operation is not free moving, then the flow sensor may be immersed and soaked in clean soapy water (see note below). The inside of the spring mechanism can be cleaned by activating it whilst submerged in the water.
After cleaning, the sensor should be allowed to dry fully prior to use.
Warning -
The plug of the flow sensor must not be immersed in water as damage will occur.

Battery Test and Replacement
To test the battery perform the battery calibration, as outlined in the procedure in Chapter 2 ‘Configuration and Calibration’, and verify that all pass criteria are met. If pass criteria are not met then replace the battery.
Battery charge retention will eventually degrade. So where retention is critical the internal battery should be replaced every three years.
Replace the Main Battery
1. Remove the two case screws in battery cover, remove cover and battery.
Battery pack
2. Fit new battery.
3. Replace battery cover and secure with 2 screws.
