5.3 Consumable Replacement Procedures
5.3.1 Draining the water bottle
Locate the drain port (figure 2) on the rear of the generator and insert the drain line. Ensure that the line is locked in position to
obtain a complete seal. Leave the water to drain into a suitable container, then press the lock downwards and remove the line.
In order to prevent contamination and prolong the life of the cell do not reuse the old water.
5.3.2 Replacing the deionizer cartridge and 100 micron water filter
Change the deionizer cartridge every 4000 hours (6 months), or if it has become contaminated.
Switch the generator into Standby mode. Remove the top front cover as shown in figure 19. Remove the water reservoir cap.
Wearing disposable gloves, remove the deionizer cartridge (figure 18, item 1) and discard. Extract the 100 micron water filter (figure
18, item 2) using the H2 filter replacement tool (figure 18, item 4). Push the tool over the filter so that the webs on the filter fit into the
slots on the end of the tool. Unscrew the filter and remove it from the water bottle as shown in figure 20.

Fit the replacement filter and ensure that it is secured into the water bottle. Refill the water bottle with deionized water, ASTM II, >1
MΩ, <1µS, filtered to <100µm, as described below, and fit the replacement deionizer cartridge.
Refit the water reservoir cap and the top front cover and restart the generator.
5.3.3 Replacing the Environmental Filters
Remove the two environmental filters (figure 18, item 3) from the vent ports by pushing the push in fitting upwards to
release. Fit the replacement filters and check that they are secure.
Note:
Environmental filters should be changed every six months as there is no visual indication of exhausted filters.
