OPERATION

 

The appliance condensate will flow through the neutralizing media, raising the condensate pH to 
a level that will help prevent corrosion of the domestic drain and the public sewer system.  

 

MAINTENANCE

 

Monitor the level of the neutralization media in the tank periodically. The pH can be checked after 
the  condensate  has  exited  the  tank  or  by  removing  the  lid  and  taking  a  sample  from  the  last 
chamber before the outlet.  Check the pH level every three months for the first year. Use a suitable 
pH test strip paper or an electronic pH meter for precise measurement.  The frequency of checking 
the pH level can be reduced to every six months or every year depending on the readings obtained 
compared to local water authority requirements.  The neutralizing media should be replaced when 
the pH level drops below the minimum level of the local water authority.  For replacement media 
contact your local AERCO sales representative.  

  Replacement  neutralization  media  for  KC,  BMK,  INN,  Recon,  MFC,  and  Modulex  series

At  delivery,  the  replacement  media  comes  in  two  clear  plastic  bags;  a  smaller  one  inside  the 
bigger (Figure 10).  The larger bag consists of larger pieces of neutralization material, while the 
smaller bag consists of smaller pellets of neutralization material. Replenish the tank with the larger 
material, then sprinkle the smaller pellets on top.
