4. Clean the arm with a lint-free towel moistened with 70% isopropyl
alcohol. Allow it to dry.
5. Reassemble the carrier:
Slide the arm back into the open end of the plate carrier.
Squeeze the arm spring against the carrier to expose the openings
for the screws and washers, and reinstall them.
6. To replace the carrier, line up the pin on the underside of the carrier
with the slot on the carrier transport rail. Snap the two carrier rail
guides onto the rail. The pin should sit in the slot.
Cleaning the Manifold, Mist Shield, and Tubing
Regular rinsing helps to keep the manifold clean, the aspiration and dispense
tubes clear, and it increases the life of the tubing.
If you suspect a particular problem is related to the manifold (for example,
clogged tubes can result in poor or uneven aspiration or dispensing), you
should perform a thorough cleaning of the dispense and aspirate tubes and
channels. When necessary, follow the
DECONTAMINATION
procedure on page
130 to disinfect the manifold and tubing.
To clean the manifold, mist shield, and tubing:
1. Run the system “dry”:
From the main menu, select UTIL SETUP SENSOR and set
VACUUM DETECTION, FLUID DETECTION, and FLOW DETECTION
to
NO
.
Connect an empty supply bottle and prime the washer until the
tubing is empty.
Important! Set the vacuum, fluid, and flow detection sensors back
to YES .
2. Turn off the washer and disconnect the power cable.
3.
Moisten a lint-free disposable towel with water, or with water and mild
detergent.
Do not soak the cloth .
4. Remove the mist shield if it is attached (see
Figure 16
in
Chapter 2,
Installation
). Wipe the inside and outside surfaces of the mist shield
with the towel. Wipe the top surface of the instrument base, and all
exposed surfaces of the instrument.
5. If detergent was used, wipe all surfaces with a cloth moistened with
water.
6. Use a clean, dry cloth to dry all wet surfaces.
