Running the unit from DC power
1. Disconnect the power cord (1) and press the ON/OFF switch (5) on the control panel to start the vacuum
pump.
Adjusting the vacuum level
• Occlude the patient tube and turn the vacuum regulator (7) clockwise to the stop.
• Observe gauge (located above the vacuum regulator). The vacuum reading should rise to -300mmHg from
zero in 3 seconds. It should max out at approximately ≥ -525mmHg. Lower levels of negative pressure will be
observed at altitude.
Battery Charging from AC Power using AC-DC Charger:
The optional Fixed Voltage Charger will not run the
pump. If battery charging from AC power is required, connect the SSCOR AC-DC charger (1) to an AC outlet.
The charger connects to the unit through the receptacle (1A) on the front panel.
DC Battery Charging from Vehicle
Connect the DC power cord to the cigarette lighter receptacle in the vehicle or hard wire the DC power cord
to the DC electrical system of the vehicle on a properly fused line in front of the master switch. Connect the
electrical line cord to the suction unit by securely attaching the charging plug (1.1A) into the receptacle (1A).
This charging method is designed to keep the battery charging at all times. If the suction unit is operated
while it is hooked up to the vehicle it will utilize the vehicle power and save its own battery for emergency
use. All SSCOR suction 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 suction unit is wired to the
vehicle battery via an automatic load switch power supply, be sure to use a filter in order to eliminate any
voltage spikes.
Battery Charging Verification
Once the unit is connected to the charging source, check the control panel (2). The “power source
connected” LED (4), when lit, shows a good connection and indicates the battery is charging.
Charging the Battery Using the 8310 Charging / Retention Bracket (Model 2309BV Only):
Hard wire the Model 8310 Charging / Retention Bracket to the hot DC circuit (in front of the master switch).
Make certain the circuit is properly fused according to appropriate vehicle standards. The vehicle electrical
system will furnish power to both run the pump and charge the battery. See page 10 for additional
information
