 HEF7 series manual  32 

 

Maintenance and cleaning 
 

Humidifier components are very easy to maintain. 
The following elements require maintenance: 

 

The irrigation pump: 

The most important thing is 

to  monitor  to  ensure  dirt  does  not  obstruct  the 
suction- 

impulsion 

circuit, 

and 

electricity 

consumption  is  below  the  power  rating  on  its 
plate. 

 

Control 

valves: 

These 

must 

be 

inspected  in  accordance  with  their 
mechanical regulation. 

 

Solenoid  valve: 

This  must  be  inspected  in 

accordance  with  its  mechanical  closure  and 
opening. 

 

Metal filter: 

This must be cleaned manually. 

 

Evaporative  panels: 

For  drinking  and  industrial 

water  supplies  their  operating  life  basically 
depends  on  the  constant  bleed-off  system  for 
mineral  salts  working  correctly  to  prevent  the 
formation of lime  deposits  on surfaces. If it  is not 
regulated properly, the panels have to be replaced 
in a short period of time, because the 
air passing through the panels becomes blocked by 
the formation of these deposits. 

 

Water tank: 

Elements holding bodies of still water 

are  renowned  for  generating  microorganisms,  and 
algae.  The  maintenance  director  must  implement 
an  inspection  plan  for  emptying  and  cleaning  the 
HEF-7  pump  tank  based  on  the  quality  of  the  air 
treated and the water supply. 

 

Regular observations are recommended for correct 
maintenance during the days following start-up, to 
find  out  how  the  specific  installation  is  behaving, 
and to 
establish  the  emptying  and  cleaning  programme. 
Similarly,  during  long  periods  of  inactivity  (summer  in 
the case 
of  humidification  for  comfort,  and  winter  for 
evaporative  refrigeration)  it  is  essential  to  totally 
empty and clean the tank. 

 

Evaporative  humidifiers  must  be  cleaned  on  a 
regular basis to prevent their contamination. All the 
surfaces  of  the  components  (panel,  pipes  and 
especially the water tank) must be disinfected using 
an appropriate solution.

IRRIGATION PUMP                           Monthly 

CONTROL VALVES                           Annually 

SOLENOID VALVES                          Annually  

METAL FILTER                                  Monthly  

EVAPORATIVE PANELS              Trimestralmente        

Quarterly WATER TANK               Trimestralmente     

 
 

Special attention must be paid to cleaning the piping system, 
and above all the junctions. 

 

In the case of the panels, the use of chemical disinfectants for 
daily  maintenance  is  not  recommended  because  it  could 
reduce panel efficiency and the useful life. If it is necessary to 
use chemical products, either because the system has 
not been operational for a long time, or for any other reason, 
an effective method is to submerge the panels in a chlorine 
disinfectant, such as sodium hypochlorite (bleach) or 
sodium percabonate. When using chlorine disinfectants, it is 
essential to take into account the formation of toxic  chlorine 
gas if it is combined with an acid solution. 

 

[Note]

 Do not forget to employ the safety measures 

of the manufacturer of the disinfectant solution.
