l Inspect the sample head weekly. If it needs to be cleaned, disconnect the dis-
persion unit from the mains power and use a bottle brush to clean it. Use a deter-
gent (e.g. Decon 90) if necessary. Rinse the head thoroughly to remove all
detergent traces.
Hydro EV clean sequence
It is best to clean the EV with the 2 beakers supplied with the unit, one for the clean dis-
persant and one for the waste. Select Clean system from the measurement progress bar,
or the Clean button from the accessory controls and follow the displayed instructions.
1. Raise the pump head and remove the full beaker that was used for the meas-
urement.
Note: The cell and dispersion unit will still contain dispersant.
2. Place an empty beaker on to the beaker holder and lower the pump head. The cell
and unit will drain, and after a pause the pump will start. While the cell drains,
rinse the removed beaker and refill with clean dispersant.
3. When the cell is drained, raise the pump head, remove the current waste beaker
and replace with the clean dispersant beaker; lower the pump head.
4. After a pause the pump will start and circulate the clean dispersant through the
system.
5. For a standard clean the process will repeat a further 2 times. With the final fill the
stirrer will pulse to remove any bubbles. The clean sequence is now complete.
Hydro SM procedures
Inspect and clean the tank and flow path
Drain and rinse the tank, then circulate clean dispersant through the cell a few times. Usu-
ally this is sufficient. However, over time deposits may accumulate on the inside of the
tank head.
l Inspect the tank once a week. If it needs to be cleaned, disconnect the dispersion
unit from the mains power and use a bottle brush to clean it. Use a detergent (e.g.
Decon 90) if required.
l Make several clean flushes to clear all traces of detergent and deposits in the tank.
