Daikin Air Handler AMST24BU1400

WARNING! Never operate unit without a filter installed as dust and lint will build up on internal parts resulting in loss of efficiency, equipment damage and possible fire

NOTE! An indoor air filter must be used with your comfort system. A properly maintained filter will keep the indoor coil of your comfort system clean. A dirty coil could cause poor operation and/or severe equipment damage.

Your air filter or filters could be located in your furnace, in a blower unit, or in “filter grilles” in your ceiling or walls. The installer of your air conditioner or heat pump can tell you where your filter(s) are, and how to clean or replace them.

You may want to ask your dealer about high efficiency filters. High efficiency filters are available in both electronic and non-electronic types. These filters can do a better job of catching small airborne particles.

Check your filter(s) at least once a month. When they are dirty, replace or clean as required.

Disposable type filters should be replaced. Confirm replacement.

Reusable type filters may be cleaned. Confirm cleaning.

Is the unit equipped with an aluminum tube evaporator coil?

Did you flush the coil with water?

WARNING! Many coil cleaners and drain pan tablets contain corrosive chemicals that can be harmful to aluminum tube and fin evaporator coils. Even a one-time application of these corrosive chemicals can cause premature aluminum evaporator coil failure.

Any cleaners that contain corrosive chemicals including, but not limited to, chlorine and hydroxides, should not be used.

Did you use one of the products listed in TP-109* to clean the coils?

The cleaners listed are the only agents deemed safe and approved for use to clean round tube aluminum coils.
