Getting Acquainted
Charging the Battery
1. Connect the dual mode battery charger (1) to a grounded wall receptacle.
2. Connect the female plug of the battery charger (1A) to the facing side of the unit (1A).
3. Check the control panel (2). The "power source connected" red LED (4) indicates a good
connection between the new-Sentinel and the charger.
4. Check the LED’s on the battery charger (1). "Power On" (21) indicates a good connection
to the AC power source. "Fast Charge" (22) will light when the battery is charging and go
out when the battery is fully charged. When the "Fast Charge" (22) light is out, you can
test the charging mode by flicking the switch (5) to the "On" position and back "Off". The
"Fast Charge" (22) light should come on immediately.
TEST FOR VACUUM. RUN THE FOLLOWING TEST WEEKLY TO ENSURE
PROPER PERFORMANCE OF THE DEVICE.
5. Attach patient tubing to patient port (12) on collection canister (13).
6. Press the ON/OFF switch (5) on control panel to start vacuum pump.
7. Occlude the patient tube, turn the vacuum regulator (7) clockwise to the stop. See Caution
- Notice, page 2 number 8.
8. Observe the gauge (8). The vacuum reading should rise to -300mmHg from the zero setting
in 3 seconds. It should max out at approximately >= -525mmHg. Un-occlude the patient
tubing.
9. 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 battery capacity has been depleted. It is time to replace the
battery.
10. If the unit is still running at full power after 15 minutes, adjust the regulator to the desired
setting, turn the device off and put it back on charge.
NOTE A: If the vacuum does not reach -525mmHg, check for a leak in the system i.e. vacuum
tubing (10), barb connections (11,12) or loose canister lid (13). Refer internal vacuum
problems to qualified personnel.
NOTE B: Reconnect the charger to the unit as soon as possible after each use by attaching the
charging plug (1A) to the receptacle on the unit (1A).
