Clean waste separator and exchange Waste cassette assembly

Be careful, as there may be blood in the cassette. First, make up some disinfectant and put this in the waste separator. Press Prime Disinfectant to pump disinfectant through the pump cassette.

Clean Separator

The waste system must be cleaned before replacing the waste pump cassette.

  1. Open the left cover and remove the waste container. The waste separator is now visible.
  2. Lift the stainless steel vacuum tube with use of the lever.
  3. Pull the waste separator towards the front of the ESR analyzer unit. (Note: The separator has two sensor connectors at the rear)
  4. Remove bacterial HEPA filter.
  5. Fill waste separator with 100ml disinfectant or 100 ml water with 2% bleach.
  6. Replace bacterial HEPA filter.
  7. Lift left cover.
  8. Lift stainless steel vacuum tube up.
  9. Insert the waste separator sliding it over the support shelf.
  10. Push the waste separator towards the rear, with the sensor connectors in the holes.
  11. Release the stainless steel vacuum tube.
  12. Replace the waste container.
  13. Close left cover.

Waste seperator type 2

Exchange Waste Cassette and blotting washer

  1. Disconnect the two tubes from the waste pump cassette.
  2. Press levers (at three o'clock and nine o'clock positions) and pull at the same time.
  3. Remove the old blotting washer ESRI090026 around the motor shaft.
  4. Clean peristaltic pump motor shaft using a tissue soaked in alcohol.
  5. Place the new blotting washer ESRI090026.
  6. Insert new waste pump cassette ESRI090921 until it clicks into place.
  7. Remove the protection caps on from the tubes.
  8. Connect the two tubes from the waste pump cassette on the luers at the steel plate under the waste pump.

Inspect or replace sample probe or outer needle

A faulty or broken needle can cause a fill time-out error or a dilution error.
If necessary replace the sample probe or outer needle.

Check and clean instrument

Prepare disinfectant: (if not already prepared).
This disinfectant is for cleaning of all external parts that are exposed to blood.

  1. Go to tab [Maintenance] and perform the [End-of-day wash] procedure.
  2. Check system for leakage.
    • Inspect the peristaltic pump tubes and connections for leaks.
    • Check that liquid does not run back after the pumps have stopped.
  3. Clean the outer needle with disinfectant
  4. Check tubing from the syringe for trapped air bubbles.
  5. Check Diluent syringe for trapped air bubbles.
