Care and Maintenance

(Weekly) Clean the metal battery contacts and the interior contacts of battery clips.
Use a cotton swab or lint-free cloth that has been moistened (not dripping) with rubbing alcohol.
Allow the alcohol to dry before using newly cleaned batteries or clips.
Do not clean batteries while the batteries are in use.

(Monthly) Unplug the Battery Charger and clean the metal contacts inside all four charging pockets.
Use a lint-free cloth or swab that has been moistened (not dripping) with rubbing alcohol.
Allow the alcohol to air dry before inserting batteries into the pockets.
Do not clean the Battery Charger while it is plugged in.

(Annually) Battery Charger must be inspected and cleaned by the hospital’s Biomedical Engineer.
Your VAD Coordinator will remind you to bring in the Battery Charger for this preventive maintenance.
The safety inspection and cleaning include functional testing and inspection.

Every six months, replace the Mobile Power Unit batteries with three new AA Alkaline batteries.
If corrosion observed, discontinue use of the MPU and call your hospital contact.

Lay the ribbon on the bottom of the compartment. Place (new) Alkaline AA batteries in the battery compartment.
Orient the batteries as shown on the orientation markings on the battery.
Replace the battery compartment cover. Use the flathead screwdriver or coin to tighten the screw
Always connect to the Mobile Power Unit when sleeping, or when there is a chance of sleep.
If there is a power failure, transfer from the MPU to another power source.
The backup battery in the System Controller will briefly power the pump while transferring to battery power.
High levels of static current may damage or harm the system and may cause your pump to stop.
While awake, you should use battery power instead of the Mobile Power Unit to power the system.
Using battery power can reduce the risk of system damage from high levels of static current.
