CARE AND MAINTENANCE

In order to maintain proper performance of your pack- aged terminal air conditioner or heat pump, it is very important that the fan and outdoor coil, the blower wheel, blower scroll, electric heater, and all drain pas- sages are thoroughly cleaned at least once per year. Carrier recommends that as a minimum, the cleaning should be conducted prior to the start of each heating season. The air inlet filters should be cleaned every month.

Depending on local conditions, more frequent cleaning of the unit may be required to ensure optimum perfor- mance and long operating life. Examples of these spe- cial conditions include areas where construction dust or heavy airborne dirt is found, or environments that promote the growth of fungus.

Some local conditions and environments can cause fungi to grow inside the air conditioner, especially on indoor blower section. Dried fungi, dirt and other foreign material are fire hazards. Be sure to clean unit according to the instructions that follow.
