drains. In order to eliminate the residues and keep the tank as clean as possible, the humidifi er also drains
after a certain number of boiling – refi ll cycles. If there is still a demand from the humidistat after draining, the
tank refi lls and starts to produce steam again.
20.15 When the humidistat is satisfi ed, the fan continues to run for a short period of time in order to eliminate
the steam from the ducts.
20.16 When everything is working fi ne, put the cover on the unit and attach it by turning the 1/4 turn latch to

Please don’t forget to leave this instruction manual with the customer.
20.18 Sequence of Operation.
* The unit will repeat this cycle until the humidistat is satisfi ed or the selected number of cycles is reached
before going to the draining cycle. If there is no more demand for humidity, the unit will automatically go on
Stand By mode until the next demand. If there is no demand for 7 days, the unit will fl ush and drain the tank.
NOTE:
The Acu-Steam board has a memory that remembers the last sequence of operation when the power is turned
off, hence the unit might start at step 2 or 3 when you put the power back on. Also, timings may slightly vary
depending on the capacity of the unit (1.5 kW, 3 kW or 4 kW), the pressure of the water inlet and the quality of
the water.
