Figure 25: Condensate neutralization tank

Figure 24 Condensate trap drainage

WARNING

If condensates are to be 

discharged into building drain 

piping materials that are subject 

to corrosion, a neutralization 

package must be used.

CAUTION

When a condensate 

neutralization package 

is installed, the pH of the 

condensate discharge must be 

measured on a regular schedule 

to ensure the neutralizing agent 

is active and effective.

Figure 23: Condensate trap 

disassembly for cleaning

DANGER

The water in the condensate 

neutralizer can cause severe 

burns to the skin.  Use extreme 

caution when servicing the 

condensate neutralizer.  Wear 

protective gloves and eyewear.
