ROUTINE MAINTENANCE Chapter 5
5 - 3
The pump is designed for easy cleaning. The routine cleaning procedure is described
under "Routine Cleaning". The Service Cleaning procedure is more thorough than the
routine cleaning procedure. Service Cleaning is recommended when conductive,
corrosive, or sticky liquids are spilled on the pump. This type of contamination can cause
corrosion, binding of moving parts, or frequent syringe related alarms/alert messages.
Prior to cleaning the pump according to this procedure, ensure that any driver movement
binding is not caused by damage to the mating surface of the lower plunger driver to the
upper plunger driver.
5.2.2.1 Barrel Clamp Cleaning
1. Remove the barrel clamp as described in Chapter 7, section 7.2.4.1.
2. Carefully irrigate the contaminated surfaces of the barrel clamp, using a soft-bristled
brush to work the solution into all corners and crevices. Open and close the clamp a
few times, to help distribute the cleaning solution.
NOTE
DO NOT IMMERSE THE BARREL CLAMP ASSEMBLY.
3. If this does not loosen the dirt, wipe with a sponge and any of the approved cleaning
agents (see Table 5-1), followed by a rinse with water or a dilute mixture of soap and
water. Do not allow the cleaning agent or rinsing agent to leak into the barrel clamp
electronics.
4. After removing all contamination, shake off excess liquid and blot the assembly dry
with a clean paper towel. Air dry overnight at room temperature.
5. Replace the zebra strip with a new one and reinstall the barrel clamp as described in
Chapter 7, section 7.2.4.2. Recalibration is required.
5.2.2.2 Plunger Drive Cleaning
(Refer to the assembly procedures in Chapter 7 for additional information.)
This procedure is to be followed only if the plunger driver cannot be cleaned with the
routine cleaning procedure.
1. Inspect the drive chamber seals (black seals at both ends of the drive chamber) for
dryness, cracks, or other damage. If any damage is evident, the pump must be
repaired.
2. Work the plunger driver and drive assembly while irrigating with one of the cleaners
listed in Table 5-1. DO NOT IMMERSE THE PUMP!
