Consumable Replacement Procedures; Draining The Water Bottle (A); Replacing The Deioniser Cartridge And 100 Micron Water Filter (B); Filling The Water Bottle (C) - Parker 20H-MD Guide D'utilisation

5.3 Consumable Replacement Procedures

5.3.1 Draining the water bottle (A)

Locate the drain port on the rear of the generator and insert the drain line (1). 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 (2) 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 deioniser cartridge and 100 micron water filter (B)

Change the deioniser cartridge every 4000 hours (6 months), or if it has become contaminated.
Switch the generator into Stand by mode and remove the top front cover and the water bottle cap.
Wearing disposable gloves, remove the deioniser cartridge (3) and discard. Extract the 100 micron water filter (4) using the H
tool (5). 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.
Fit the replacement filter and ensure that it is secured into the water bottle. Refill the water bottle with deionised water, ASTM II, >1 M , <1 S,
filtered to <100 m, as described below, and fit the replacement deioniser cartridge.
Refit the water bottle cap and the top front cover and restart the generator.

5.3.3 Filling the water bottle (C)

The use of any water, other than deionised water (ASTM II, >1 M , <1 S, filtered to <100 m) within this generator will damage and reduce the
life time of the hydrogen cell.
Remove the top front cover and the water bottle cap (6). Fill the water bottle using fresh deionised water to a level approximately 15mm below
the upper lip of the neck of the bottle.
If the generator is powered during refilling, an audible and visual indication will be given by the generator when the correct level is reached, and
the LCD will display "Water Full" message. Once full replace the water bottle cap and top front cover.
Note: If the water has been changed due to high conductivity, the deioniser cartridge must also be changed.
