BATTERY CHARGING

On 7305P series, the units are equipped with a
factory-installed rechargeable battery. The unit will
have a light for low battery and charge indication. On
7305D series, the units are not factory equipped with a
rechargeable battery; check with your equipment
provider to determine if your unit has been upgraded
with a rechargeable battery.
When you connect the unit to an AC or DC power
source using the AC adapter or DC power cord, the
green external power light will illuminate. The yellow
charge indicator will illuminate. Verify that this
illuminates when charging begins. As the charge nears
a full charge, the yellow LED may flash on and off for
several minutes. This is normal.
NOTE – Charge battery for a minimum of 17 hours
before first use.
NOTE – Fully recharge battery after each use. The
unit will continue to float charge the battery after the
charge indicator turns off, so leave the unit connected
to AC when not in use.
CAUTION– Discharging the battery completely will
shorten the life of the battery. Do not operate the unit
more than a few minutes if the low battery indicator
light is lit. Recharge as soon as possible.
NOTE – Unit run time will decrease as the battery
ages.
NOTE – Unit run time will also be reduced by letting
the battery sit at a discharged state for extended
periods.
STORAGE NOTE - Battery should be charged for a
minimum of 17 hours prior to storage, and at least
once every 6 months. Important - If battery recharge is
delayed beyond 6 months, battery may be able to
provide full run time after completion of 3 full charge
and discharge cycles.
NOTE– A fully charged battery will provide
approximately 60 minutes of continuous operation at a
zero vacuum level (free flow). Operation time will
decrease with higher vacuum levels.
NOTE– When charging the battery, use an external
power source and verify that the charge light
illuminates when the unit is in the "Off' position. If the
battery does not charge, please be sure the model you
are using has a battery installed prior to contacting
your authorized DeVilbiss Healthcare provider.
NOTE– The internal rechargeable battery is sealed
lead-acid. Contact your local authorities for instruction
on proper disposal.
NOTE– Do not connect the AC adapter to an outlet
controlled by a switch to ensure power is supplied to
unit at all times.
NOTE– Do not connect the DC power cord to an outlet
that is not constantly energized.
