14. WATER QUALITY, AIR QUALITY AND MAINTENANCE CONDITIONS
Water quality, air quality and maintenance conditions for the FISAIR high efficiency inorganic panel reaches
10,000 h in operation.
[Note]: When the water to be supplied to the HEF2 requires treatment, this must be notified in advance
on the order, as different improvements in the HEF2 design are needed, depending on whether it is
softened or reverse osmosis water. Failure to provide this information could lead to different parts of
the equipment being damaged.
Water quality conditions: (for 10000 operating hours)
1. Conductivity: Conductivity: 60-350 µS/cm, inclusive. *)
2. Total hardness: (as CaCO3) Total hardness 20-100 mg/l, inclusive.
3. Ionic silica: (Si02) < 30 mg/l
4. Iron: (Fe) < 0.2 mg/l
5. Oils and fats: < 2 mg/l
6. Total dissolved solids: < 450 mg/l
7. pH: 6-8
8. Water quality standards described in table on pages 72-73.
*) maximum conditions 1000
μS / cm. The higher the conductivity, the shorter the hours of operation.
A table of required chloride (Cl) values for each type of water is attached. Damage caused by chlorine
corrosion is not covered by the FISAIR guarantee policy.
(*): When less than 60
μS/cm, Reverse Osmosis water
can be used between 30-60
μS/cm. For values below
30
μS/cm, contact FISAIR.
Air quality conditions: Healthy air. Recommended pre-filter F7.
Maintenance conditions: The cleaning protocol is not to extend the final life, but to maintain the expectation
of 10,000 h in operation. This must be done once a year.
Remark: Humidifier cartridges are wearing parts and are not covered by the warranty.
