20. Start-up and Test Procedure
20.1 Turn the breaker “ON” to supply power to the humidifi er. The green light comes ON to confi rm that the
unit is ready to work.
20.2 Test of the On/Standby button. Press the white button once. The green light goes OFF then fl ashes,
indicating that the unit is in standby mode but still powered. Press the white button again and keep it depressed
for 3 seconds to power the humidifi er. The green light will come ON, confi rming that the unit is ready to work.
20.3 Turn the humidistat clockwise past the middle of the scale to create a demand for humidity.
20.4 The tank fi lls to the proper water level.
20.5 The fan control starts the fan to move the air as the humidifi er starts boiling water and produces steam.
If the fan cannot start, the humidifi er suspends the ongoing operation. If the air pressure is insuffi cient, the unit
will stop by itself. Please note that it may take a few minutes to bring the water to a boil. The steam exits the
water tank through the steam outlet and steam hose.
20.6 The steam moves through the hose to the diffuser and is released into the warm air duct where it mixes
with the moving air.
20.7 As water evaporates in the tank, the electric valve opens as needed to maintain the proper water level.
20.8 When the humidity reaches the desired level the humidifi er stops producing steam. In order to eliminate
the residues and keep the tank as clean as possible, the humidifi er 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.
20.9 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.
20.10 When everything is working fi ne, put both covers back on the unit and attach them with the two screws
(electrical cover) and by turning the 1/4 turn latch to the right (tank cover).
20.11 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
ready mode until the next demand. If there is no demand for 7 days, the unit will fl ush and drain the tank.
