MONTHLY CLEANING

AIR FILTERS — The indoor and vent air filters should be cleaned once per month. Filters that are not cleaned become clogged and will restrict airflow. This may lead to major component damage. If a filter becomes torn, has holes, or other damage, replace it with a new one. Replacement filters are available through Carrier Finished Goods and Carrier Replace- ment Component Division.

CLEANING THE INDOOR AIR FILTER — Two air filters are located in the unit’s front panel. To remove each filter simply grasp each filter handle with both hands and gently pull the filter up and away from the unit. See Figure 21.

REPLACING THE INDOOR AIR FILTER — Remove the indoor air filter as detailed in Cleaning the Indoor Air Filter. If damaged, use a filter replace- ment with the Carrier Part No. AIR-FILTER-10PK, available through Carrier Finished Goods and Carrier Replacement Component Division.

NOTE: Both filters are completely interchangeable.

CLEANING THE OUTDOOR AIR VENT FILTER

1.Remove the unit chassis from wall sleeve as described in the General Disassembly section of this manual. Refer to Remove the Unit from the Wall Sleeve section.

2.Swing open vent door. The filter is located directly behind the vent door. See Figure 22.

3.Once the filter is accessed, it may be cleaned using either a vacuum cleaner, or a soft bristle brush and a small amount of mild dish detergent. If detergent is used, remove detergent residue with a gentle, clean water stream. Allow the filter to air dry.

REPLACING THE OUTDOOR AIR VENT FILTER — If vent filter requires replacement:

1.Open vent door to access vent filter.

2.Remove vent door from hinges.

3.Using a small flat head screwdriver, pry the filter from the partition.

4.Replace vent filter using Carrier Part No. 52CQ500144.

5.Reverse Steps 1-3 to reattach vent door.

CHASSIS

Occasional cleaning of the exterior surfaces of the PTAC unit optimizes the unit’s appearance and removes particles that may enter the air system. See Figure 23. Mild detergents clean and reduce electro- static charges on the plastic components of the PTAC unit.

Use a clean cloth or brush to gently wipe exterior sur- faces. Be careful not to push dirt or other fibers into the unit’s interior components. Accessible wall sleeve surfaces should also be wiped clean.
