CHAPTER 10 – MAINTENANCE
10.21 Condensate Trap and Neutralizing Reservoir Maintenance
The condensate trap and neutralizing reservoir must be checked every year and cleaned if
required. Follow the steps below to properly inspect, refill or replace the condensate neutralizing
reservoir and media:
Monitor the level of the neutralization media in the reservoir periodically. The pH can be
checked after the condensate has exited from pipe "A" of Figure 4-8. 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 pH level inspection 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 AERCO.
To inspect and maintain the condensate system, perform the following:
