Chapter 5 ROUTINE MAINTENANCE
5 - 4
3. Extend the plunger clamp and direct a low-velocity stream of warm water from a water
bottle onto the driver assembly. Direct the stream carefully, to minimize the amount of
water that enters the drive compartment.
4. Remove the upper plunger driver (see Chapter 7 for details).
5. Surface contamination can be cleaned by wiping with a sponge or cotton swab and
any of the Baxter® approved cleaning agents. Do not allow cleaning agents to flow
into the drive compartment.
6. If the drive compartment is contaminated, flush the drive area with warm water. Hold
the pump in a horizontal position, so that water runs out the side of the drive area, and
not the ends.
7. Dry the plunger and drive assembly by blotting, followed by a gentle air stream or
letting the unit stand unused overnight.
8. Reinstall the upper plunger driver (see Chapter 7 for details). Recalibration is
required.
5.2.2.3 Return to Service
The pump must successfully complete the Functional Tests described in Chapter 4 before
being returned to service. If there is a problem, the pump must be repaired, recalibrated,
and retested.
NOTE
Because the above procedure requires skill and careful attention to
detail, the manufacturer cannot assume responsibility for damage
caused by ingress of cleaning agents or other fluids into sensitive
areas of the pump.
