1. Disconnect the pump wires from the printed circuit board (PCB), then disconnect all
tubing from the pump output elbow.
2. Remove the three (3) (phillips) screws from the vibration bumpers. Also, remove the
four (4) screws located on top of the pump head. Remove the pump head. This will
expose the diaphragm.
3. Using a mild soap solution, wash the surface of the diaphragm.
DO NOT
allow any
solution to ingress to the diaphragm and into the pump chamber.
CAUTION: Never flush your pump with any liquid solution, as this may
damage your pump.
Wash the underside of the pump head with the same soap solution as used on the
diaphragm.
4. Thoroughly dry with a soft cloth. Next, reassemble the pump head, reinstall, and
tighten the four screws. Reconnect the pump wires to the PCB and all tubing to the
pump and regulator and follow reverse order of disassembly. Ensure that your unit
performs according to the Device Specifications Section.
B) Vacuum Regulator Cleaning
The suction regulator may accumulate aspirant after the pump has been in service for an
extended period of time. When disassembling the pump for cleaning, it is suggested that
the regulator also be cleaned as a preventative measure.
1. Remove the regulator by disconnecting the silastic tubing and loosen the locknut
(make note of the orientation of all tubing and the regulator body).
2. Disassemble the regulator and wash all parts with a mild soap solution. Wipe all parts
thoroughly dry with a piece of cotton cloth before reassembling the regulator. Rein-
stall and reconnect the tubing.
