20. Start-up and Test Procedure
20.1 Take the 5/16 dia. plastic tube previously uncoiled and push one end on the connector located at the
bottom of the overfl ow pan. Please see Fig. 20a and Fig.20b.
20.2 Install the overfl ow pan under the tank by sliding it on its holding screws. You don’t have to tighten the
screws.
20.3 Reconnect the white wire for the overfl ow sensor on the water pan.
20.4 Cut the two drain tubes and insert them in the rigid pipe. Note that the main silicon drain tube must
have a minimum length of 24” below the bottom of the unit to allow the siphon to work properly. It is
important to leave an air gap between the soft tubes and the rigid pipe.
20.5 Turn the handle of the water supply valve (fully counter-clockwise) to bring water to the humidifi er and
let the water pressure enter the system.
20.6 Follow the water supply path completely and carefully check for leaks at the fi ttings.
20.7 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.
20.8 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.
20.9 Turn the humidistat clockwise past the middle of the scale to create a demand for humidity.
20.10 The tank fi lls to the proper water level.
20.11 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.
20.12 The steam moves through the hose to the diffuser and is distributed by the fan.
20.13 As water evaporates in the tank, the electric valve opens as needed to maintain the proper water level.
20.14 When the humidity reaches the desired level the humidifi er stops producing steam and automatically
