5. To reassemble the charger, ensure
all connecting wires are secure.
6. Insert the correct length of screw
into the hole shown and tighten.
case, be careful of connecting
wires.
1.2 Replacement of AC Power Fuses in Charger Unit
1. Remove the pump from charger.
2. Connect the charger to AC power.
3. Check that the AC power icon is displayed, if not perform the following
steps:
a. Remove the AC cable from the power outlet.
b. Disassemble the charger following the “Disassembly /
Assembly of Charger” instructions above.
c. The fuses are protected by a plastic cover on the back of
the AC power inlet, remove this cover.
d. Remove the fuses from the fuse holder on the charger
PCB, and using an ohmmeter check electrical continuity.
e. If necessary, replace with a new fuse of same value, type
and voltage. F1, F2 20mm 800mA Slow Blow.
f. Replace plastic fuse protection cover.
g. Reassemble charger in reverse order.
4. Perform Operational Checklist and Performance Acceptance Test
1.3 Checking Charger Voltage
WARNING: Voltage present on internal components may cause
severe shock or death upon contact. The following procedure requires
measuring voltages with the case open. Use care when making these
measurements.
1. Check the input voltage on the AC/DC converter (should be between
100-240 V). If not, check fuses. If so, check the output pins of the
AC/DC converter should be 10V±0.5v. If 0v, replace the PCB.
2. Verify the voltages diagrammed below.
