Chapter 7 Maintenance and Repair
7.1 Routine Maintenance
The following routine maintenance should be performed at the intervals specified:
Hospital Engineer or Olympus - Annually:
- Check that the power cable is in good condition.
- Detach the pump head (Section “Pump Head Replacement” on page 46), and
wipe the pump head thoroughly with a mild detergent solution. Check moving
parts of the pump roller for freedom of movement.
- Check the unit externally for signs of damage.
- Perform electrical safety tests in accordance with EN IEC 62353:2008. It is
recommended that testing includes:
1. Protective earth resistance. Detach the pumphead as described above and
test to the three torx head screws.
It is not necessary to test the remote control connector on the rear panel
as electrical separation from the mains part is ensured inside the unit.
2. Leakage currents.
3. Insulation resistance.
4. Functional test.
7.2 Checking the Flow Rate
The pump head is a consumable. Its performance will deteriorate as the number of usages
increases. The pump head may have deteriorated if the flow rate is low, if the strength of water flow
seems weak or if it takes a long time for water to appear. If the contents of Chapter 10
"Troubleshooting" do not help you to solve the problem, measure the water flow as shown below. If
the water rate is insufficient we recommend that you replace the pump head.
1.
Insert the specified water tube (MAJ-1607 or MAJ-1608) to the pump head.
2. Set the flow rate to "9" and pump until water exits from the tube in order to purge the water
tube of air.
3. Put the end of the tube in a container (beaker etc) with volume measurements on it, and
pump for 20 seconds.
4. When the flow rate falls below 200ml (equivalent to 600ml/min), replace the pump head
referring to Section “Pump Head Replacement” on page 46.
7.3 Pump Head Replacement
Replace the pump head as follows:
1.
Detach the pump head
Switch the power supply OFF and then rotate the pump head 45° anti-clockwise with one
hand, while pressing and holding the pump head release lever with the other hand. Slowly
take the pump head off the mounting plate (Figure 7.1).
