2.4 Water Reservoir
The HygroGen2 requires 50-80ml of distilled water in the internal reservoir. Insufficient water will
deactivate the humidification system. As long as extreme care is taken not to overfill the water reservoir,
the HygroGen2 may be filled and emptied either with the unit powered up or shut down.
To fill the HygroGen2
1. Insert the tube of the dosing syringe, with the plunger fully depressed, 10mm into the water
port and extract any residual water by drawing out the plunger.
2. Depress the collar on the water port (Figure 1(4) above) and remove the dosing syringe tube.
Wipe up any spilt water with an absorbent cloth immediately.
3. Fill the dosing syringe with 80ml of distilled water. Insert the end of the dosing syringe tube
firmly back into the water port and discharge the syringe steadily. (If water leaks during this
operation the filler tube is not correctly inserted in the water port.)
4. Depress the collar on the water port to remove the dosing syringe tube. Wipe up any spilt water
with an absorbent cloth immediately.
5. A water level indicator is shown in the Settings Screen (see section 3.4.5
).
Caution: Do not overfill the HygroGen2
Overfilling of the unit will result in poor humidification and, in extreme cases, water may be pumped
into the chamber. If the HygroGen2 is overfilled, the humidifier should be fully emptied and then refilled
with 50-80ml of water (as described above). If there is water present in the chamber of the HygroGen2,
this should be removed using an absorbent cloth. Ensure the HygroGen2 is switched off and the mains
power unplugged before manually drying the chamber.
