Filter Removal - Amana GUI* Installation Instructions Manual

Become familiar with filter location and procedures for
removal, cleaning and replacing them. If help is needed,
contact the installer of the furnace or a qualified servicer.
AIR FILTER - UPFLOW FURNACES
To remove the external upflow filter from the external filter
rack, disconnect electrical power to the furnace and follow
the directions provided with the external filter rack kit.
If the filter is in the furnace retaining rails, remove it as
follows: Pull off the non-louvered door. The blower motor
will automatically stop through the interlock switch.
Grasp the lower portion of the filter, lift up to disengage it
from the lower railing, move towards blower, drop filter
down. Pull filter outward (Figure 39).
Replace the filter with the same type and size filter when
needed.
Remove the two front panels (louvered panel first). Using
a vacuum cleaner, clean out the blower area, external filter
rack area, and the adjacent area of the return air duct.
Clean, wash and dry a permanent filter. When using a metal
filter, both sides should be sprayed with a dust adhesive as
recommended on adhesive container. Spray adhesives for
use with permanent metal filters can be found at some
hardware stores. To install filter follow the directions pro-
vided with the external filter rack kit. BE SURE AIRFLOW
DIRECTION ARROW POINTS TOWARDS THE BLOWER.
When the filter is located in the bottom of the furnace on a
bottom return system the filter is held in place by a wire filter
retainer. To change and clean the filter, push back and up
on the wire filter retainer to release it from under the front lip
of the basepan. Slide the filter out and follow cleaning or
replacement instructions above. Replace filter opposite of
removal.

Filter Removal

AIR FILTER - COUNTERFLOW FURNACES
A furnace mounted filter rack, shipped with the furnace, can
be used in counterflow installations.
NOTE: If using Media Air Cleaner MAC1 or Electronic Air
Cleaner EAC5, follow the instructions that came with the air
cleaner for proper filter removal, cleaning, and replacement
procedures.
The furnace-mounted filter rack is mounted on the top of the
furnace. Two filters fit into the rack and rest against the
sides of the return air plenum, forming a "V" above the
furnace.
Inspect the filters frequently and clean or replace when
necessary. In some installations, the filters can be in-
spected only after the electrical power is disconnected and
the optional access door in the return air plenum removed.
If the access door is not present, proceed as follows:
1. Disconnect the electrical power.
2. Remove the non-louvered door from the furnace.
3. Remove the left filter by reaching to the left side of the
blower, pushing the filter up slightly to remove it from
the filter rack, and pulling it down to the left of the blower
and out the blower door. Repeat with the right filter.
4. Inspect filter. If your dirty filter is the disposable type,
replace dirty with the same type and size filter. If your
dirty filter is a permanent metal filter, clean as follows:
• Wash, rinse, and dry the permanent filters. Both
sides should then be sprayed with a filter adhesive as
is recommended on the adhesive container. Many
hardware stores stock spray adhesives for use with
permanent filters.
• If badly torn or uncleanable, these filters must be
replaced by equal size permanent, high velocity
filters. Throwaway filters must not be used as re-
placement for permanent filters. Under normal use,
permanent filters should last for several years.
5. To reinstall the filters, first MAKE CERTAIN THE AIR-
FLOW DIRECTION ARROW POINTS TOWARDS THE
FURNACE. Then insert the filters from the left side of
the blower. Starting with the right filter, push the filter
into the plenum so that the bottom of the filter rests in
the filter rack and the upper edge rests against the side
of the plenum. Repeat with the left filter (Figure 40).
