For opmal performance the sucon device is to remain plugged in whenever the device is not in use. If for
any reason poor baery quality is suspected, a baery test should be conducted.
Baery Test
Run the following test whenever poor baery quality is suspected to ensure proper performance of the
device.
1. Confirm the power cord is supplying power to the device. Check the power indicator light on the control
panel.
2. Remove the power cord and run the unit from its internal DC baery.
3. Check for vacuum by occluding the paent tube and set the vacuum regulator to the maximum vacuum
seng. Un‐occlude the paent tubing.
4. Allow the unit to run for 15 minutes on DC power. If the unit stops or slows during the 15 minutes, it is
possible the baery capacity has been depleted. It is me to replace the baery.
5. If the unit is sll running at full power aer 15 minutes, adjust the regulator to the desired seng, turn
the device offand put it back on charge.
6. Reconnect the unit to the charging source as soon as possible aer each use
SSCOR recommends replacing the baery aer 3 years. Replacement baeries may be purchased at
shop.sscor.com.
BATTERY CHARGING SUGGESTIONS
It is important to keep the baery connected to the charging source at all mes when the unit is not in use.
In order for the S‐SCORT® III baery to operate at its maximum efficiency, it must be charged from a power
source that will bring the voltage level of the baery up to the 13V DC operang range. This S‐SCORT III
model is equipped to charge the baery two ways, with a AC/DC baery charger (15) or a DC power cord for
direct connecon to the vehicle (17).
An acve vehicle, running calls around the clock, will do well to charge the S‐SCORT III from the vehicle’s DC
charging system. The preferred method of charging the S‐SCORT III is to wire the DC power cord to the
vehicle DC power system on a properly fused line in front of the master switch. This charging method is
designed to keep the baery charging at all mes. If the sucon unit is operated while it is hooked up to the
vehicle it will ulize the vehicle power and save its own baery for emergency use. All SSCOR, Inc. sucon
units have a diode to prevent drawdown from the pump to the vehicle electrical system and a fuse to protect
the pump from vehicle electrical surges. If your sucon unit is wired to the vehicle baery via an automac
load switch power supply, be sure to use a filter in order to eliminate any voltage spikes.
A vehicle running infrequent calls does not charge itself oen enough to keep baeries in the 13V DC
operang range and should rely on the S‐SCORT III AC/DC baery charger when the vehicle is connected to
the shore line. In this instance the DC power cord should be used as a backup source of power to run the
S‐SCORT III from the vehicle during paent transport. To ulize the 115V AC baery charger, the sucon
pump must be removed from the vehicle and charged from an AC outlet or the charger must be plugged into
a “shore‐line” outlet in the vehicle. Whichever charging method is chosen, remember to keep the unit con‐
nected to the charging source whenever the unit is not in use.
