4.7 REPLACING THE RESERVOIR
Use standard antistatic precautions when handling the electronic PCB’s.
Remove the old reservoir
Disconnect the 14 way ribbon cable from the processor PCB assembly to the
valve
driver PCB assembly
at PL4 and the small 4 way connector from the power supply
assembly at PL3. (see Figures 6 and 7).
Pull off the air supply tube from the
compressor
at the reservoir nipple.
Remove the three screws and washers holding the
reservoir
to the case.
Pull off the patient right air supply tube at the reservoir port.
Unclip the
moisture drain assembly
from the compressor chassis and pull off the tube
at the reservoir nipple.
Lift up the reservoir and pull off the patient left air supply tube at the reservoir port.
Remove the reservoir from the case.
Dismantle the old reservoir
Pull off the air tubes to the pressure transducer at the reservoir ports.
Disconnect both valve coil connectors from the valve driver PCB assembly at PL1
and PL2.
Remove the three screws and washers securing the valve driver PCB, and remove it.
Remove the three rubber reservoir mounting bushes.
Remove the fill and vent valves from the old reservoir
Remove the four knurled nuts and rubber washers from the fill and vent valves and
pull off the coils, noting the position of each valve coil.
Use a
tubular valve spanner
to undo the four valves. Be careful not to let the valve
pistons fall out and take note of the relative positions of the valves on the reservoir.
Remove each piston and blow out the inside of the valve stem with compressed air.
With an Isopropyl Alcohol (IPA) swab, wipe the valve stems clean. Inspect the pistons
for wear or damage and replace if necessary. Use the IPA swab to clean each piston.
Discard the old reservoir.
Replace the fill and vent valves onto the new reservoir
Fit the three rubber reservoir mounting bushes into the new reservoir.
Insert the fill valve pistons into the valve stems and replace the valve assemblies into
the new reservoir (the end with a single reservoir mounting ring), and tighten. Insert
the vent valve pistons into the valve stems, replace the valve assemblies into the
remaining positions on the reservoir, and tighten.
DO NOT OVERTIGHTEN, AS THIS WILL DAMAGE THE VALVE STEM
