3. Verify that the green LED on the AC Power Adaptor is lit while plugged in and a plug icon
appears on the Pump’s Charging screen.
4. Verify legibility of all labels on the AC Power Adaptor Module.
5. Record the findings on the Preventive Maintenance Check Sheet.
Preventive Maintenance Pump Tests
WARNING Flow Rate Inaccuracy.
Rate accuracy can be affected by variations of fluid viscosity, fluid
temperature, head height or back pressure, or any combination
thereof. In addition to IV set specific warnings, the following can
cause flow rate inaccuracies and must be avoided:
Incompatible brand IV sets and compatible brand IV sets with
unusually large or small diameters or unusually stiff materials.
Using a dropped, damaged, dirty or wet Pump.
Pressurizing IV bags.
Non-vented IV sets with rigid non-vented containers.
Vents on sets or burettes left in the closed position when they
should be open.
Using Minidrip chambers for flow rate settings greater than
200 mL/hr. Doing so may influence flow rate accuracy and cause
air in line or upstream occlusion alarms.
Laying the IV container flat. Doing so may influence flow rate
accuracy and cause upstream occlusion and air in line alarms.
Exceeding 500 mL/hr flow rate settings when using sets with
backcheck valves. Doing so may influence flow rate accuracy or
cause air in line or upstream occlusion alarms.
Flow rates above 300 mL/hr may cause fluid to be siphoned from
the primary container during a secondary infusion. For information
on secondary infusions, refer to the device’s Operator’s manual.
NOTE: Not applicable with non-DEHP tubing because 250 mL/hr is
the maximum flow rate per warning statement.
WARNING Use the Specified Manufacturer’s IV Set.
A label located on the top of the Pump indicates the specific type of IV
tubing that the Pump has been calibrated for. The use of other
manufacturers’ brands or type tubing could produce Pump
inaccuracies that could be unsafe for patients.
WARNING Do Not Reuse Tubing.
Do not reload pumped-on tubing (the tubing segment previously used
in the pumping channel) into the pumping channel. Doing so will
cause alarms and adversely affect flow rate accuracy.
