This section describes the cleaning procedure to be used to secure the correct
function of the instrument on a monthly basis.
The Monthly Cleaning procedure takes approximately 10 minutes, instructions
are as follows:
Clean the aspiration probes using an alcohol wipe.
Fill a cup with 10 ml 2% hypochlorite (Bottle # 2 from Boule Cleaning Kit) and one
cup with 18 ml diluent. (Recommend use of dispense function for obtaining diluent,
see Section 5.5: Dispense Function.)
Aspirate the hypochlorite as a pre-dilute sample.
Run 2 blank samples by aspirating diluent as a pre-diluted sample.
Perform a background check, in pre-dilute mode, to verify all values are within range.
See Section 5.3 for more details.
This process will decrease the risk of debris material building up in the
instrument system. This should be performed at least once a month or every
1000 samples. This procedure will take 15 minutes to complete.
Once this procedure is started the operator will be unable to abort the cycle
until it is completed.
Prematurely aborted the cycle could cause erroneous patient results if system
is not cleaned properly.
Fill a small container with 5 ml of Enzymatic Cleaner (Bottle #1 from Boule
Cleaning Kit).
If system has the optional Cap Piercer or Sampling Device, fill a CLEAN standard
4.0 – 5.0 ml tube half full with Enzymatic Cleaner.
From Main Menu press [ADVANCED], then [MAINTENANCE] and then press
[CLOT PREVENTION].
For Cap Piercer: Place filled cleaner tube into cap piercer, same as a normal
sample analysis, close the door, and go to Step 4.
For Sampling Device: Place filled cleaner tube into Position 1 on wheel, lock
wheel into place, and go to Step 4.
Hold the container (with cleaner) under the OT probe, submerged in cleaner, press
[OK] to confirm. Do not remove container (with cleaner) for at least 5 seconds after
aspiration has stopped. (This is important as Cap Piercer and Sampling Devices will
take a few extra seconds to perform aspiration before the OT begins to aspirate.)
The system will then perform the cleaning process for all analysis modes
simultaneously, and upon completion instrument is ready for next analysis.
Perform a background check to verify all values are within range. See Section 5.3 for
more details.
When necessary, gently clean the display with a soft cloth, slightly moistened
with water and a mild soap. Dry carefully.
