Evap 8
¹ See chapter 10 for version adjustment
Section 7 – Maintenance
The Evap humidifier is equipped with a removable EVAP cassette
(article code 351025) in which an EVAP matrix and LegioSafe filter are
mounted. The matrix cannot be cleaned. The EVAP cassette must be
replaced if the RV% measured by the duct sensor (SHC80) is no longer
above 50%.
If this happens, an alarm is generated. See chapter 6. The service life
depends on the number of dissolved minerals in the water. The water
hardness is an indication of this. With a water hardness of> 9dgH, the
service life is probably shorter than the service indication.
The LegioSafe filter is in the EVAP cassette. The lifespan of this is
determined by the number of sediments in the water. The service indication is valid for water that has a TDS
value of less than 350ppm. (TDS Total Disolved Solids)
If you want to know what the water quality is in your area, you can request this from your water company. If
these values are higher in the water, we advise you to take appropriate measures. For example, consider a
sediment filter or a reverse osmosis water filter.
If the values are higher than stated in table 4.1, the service life of the cassette is shorter.
The Evap cassette must be replaced at least every 2 years or if the service indicator light for filter replacement
comes on. The visible service message is an LED light (next to the key symbol) on the bottom of the humidifier.
