Maintenance And Cleaning - 4200 Series

Serenity is easy to maintain. The air filter in the return air duct of Serenity should be replaced on a regular basis to ensure proper operation and to maintain overall efficiencies. Steffes recommends changing filters every 90 days. No additional routine maintenance is required. If utilizing a heat pump or air conditioning system with Serenity, the indoor coil of the device should be cleaned periodically as dirt accumulation may reduce system efficiency. It is important to follow the manufacturer’s maintenance and cleaning recommendations for these devices.
