MONTHLY CLEANING
Ⅲ 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. Re-
placement filters are available through Carrier Finished
Goods and Carrier Replacement Component Division.
Ⅲ CLEANING THE INDOOR AIR FILTER — Remove
the indoor air filter as follows:
1. Remove the front panel to access the indoor air filter.
To remove front panel, grasp panel firmly near the
top of each side. Lift upward and pull forward. It is
not necessary to use excessive force. See Figure 1.
2. To remove the indoor air filter, gently grasp the
2 filter tabs, push down, and pull out. See Figure 22.
Once the indoor air filter has been removed, use a
vacuum cleaner, or a soft bristle brush and a small
amount of mild dish detergent to gently wash the
filter. If detergent is used, remove detergent residue with
a gentle, clean water stream. Let the filter air dry. Be
sure to reinsert the filter into the unit.
Ⅲ REPLACING THE INDOOR AIR FILTER — Access
and remove indoor air filter as detailed above in Clean-
ing the Indoor Air Filter. Use a filter replacement with
the Carrier Part No. AIR-FILTER-25PAK, available
through Carrier Finished Goods and Carrier Replace-
ment Component Division.
