4. Maintenance  
4.2 Verifications and periodic maintenance 

 

 
The following periodic procedures are to be followed to maintain trouble free operation: 
 

OPERATION 

EVERY 

PROCEDURE 

 
 
 
Strainer check and 
cleaning  

 
 
 
Every 5 days 

Check and clean  

 

 
 
 
 
5 micron cartridge 
replacement 
 

 
 
 
 
Every  15-20  days  in 
average  conditions  (4 
hours/day usage).  
 

Unscrew anticlockwise the filter 
holder.  

 

 

 
 
 
Active carbon filter 
replacement  
 

 
 
 
Every 6 months 
 
 

 

 

 

Purge periodically 
the air from the 
system, opening at 
45° for a couple of 
minutes the 
depressurization 
valve  

 
 
 

Every 15 days 

 

 

Check the pressure on the manometer located on 
the front panel. 
The  working  pressure  depends  on  many  factors 
such  as  water  temperature,  salinity  level  of 
seawater, 

battery 

voltage, 

cleanliness 

of 

membranes and type of installation. 
The  pressure,  under  mid  range  working 
conditions  is  approx.  6,5-7    BAR.  There  is  a 
small  pressure  loss  ,  in  the  range  of  0,2  Bars, 
during the cycle.
