11.  Start-up procedure 

We  recommend  to  strictly  following  this  start-up  procedure  in  order  to  avoid  any  anomaly  resulting  from  wrong 
cleaning of the components. 
In case of problem or discrepancy see section 14 

– Troubleshooting guide. 

 

1.  Make sure that mechanical, electric and plumbing connection are done and secured. 
 
2.  Make sure that low voltage control circuit is done and correct. 
 
3.  Turn on the water shut off valve (outside of the humidifier) and check that the drain connections are 

connected to the main drain line of sufficient diameter. 

 
4.  Turn on the power to the humidifier from the circuit breaker disconnect. The POWER indicator should go on. 
 
5.  Push the TEST button located on the main pc. Board. This pc. Board is located in the electrical 

compartment. 

 
6.  This will start up a pre-programmed start-up cycle. This start-up cycle will test functions of the humidifier and 

will flush out any dirt in the humidifier and supply lines. 
This cycle will last about 1 hour. 
Note:  
a) The front panel rocker switch will not affect the performance of the start-up cycle. 
b) In the case of modulating humidifier, there must be a demand signal of at least 50% for the start-up cycle 
to operate correctly. 
c) To bypass at any time the start-up cycle and to proceed directly into normal operation, press the RESET 
button located on the main pc. board. 

 
7.  The front panel rocker switch may be left in the AUTO position during the start-up cycle. This will result in 

normal operation of the humidifier as soon as the start-up cycle is finished. 

 
8.  Your humidifier is now fully operational.
