To empty the HygroGen2
1. Insert the tube of the dosing syringe, with the plunger fully depressed, 10mm into the water
port and extract any water by drawing out the plunger.
2. Depress the collar on the water port to remove the dosing syringe tube. Wipe up any spilt water
with an absorbent cloth immediately.
3. Distilled water discharged from the HygroGen2 may be stored safely and reused at a later date.
Note: The HygroGen2 should always be emptied if it is being shipped or stored (see
Preparing the Unit for Transit or Storage
). This will prevent ingress of water into the chamber should
the unit be inverted and prevent possible frost damage.
Water Quality
The HygroGen2 should only be filled with distilled water.
As a precaution against any microbial and algae water contamination, HygroGen2 incorporates an Ultra
Violet (UV) sterilisation lamp within the water reservoir. No user intervention is required - HygroGen2
auto-cycles the process.
Under no circumstance should the water reservoir be opened by non-qualified personnel. Direct
exposure to UV lamps can cause burns or blindness.
