Limited Warranty

August 1, 1997

This warranty gives you specific legal rights and you may have other rights

which vary from state/province to state/province.

Warrantor:  Allied Air Enterprises Inc., 215 Metropolitan Drive, West Columbia, SC 29170

These Allied Air Enterprises Inc. products are available under the following names:  Air Ease, Armstrong Air

Subject to the limitations stated in this warranty, we warrant to the first buyer for use the residential cooling unit, when installed, operated and
maintained as required by this warranty, to be free of defects in workmanship or material for a period of 5 years in residential installations
(1 year in non-residential installations) from the time of installation.  We will replace any defective component without cost or expense to you
except for the costs of delivery and labor for removal and replacement of the defective component.

4SCU14LE Series air conditioners carry a 10-year compressor warranty.

Your new equipment must be properly installed, operated and maintained in accordance with the unit installation, operation and maintenance
instructions provided with each unit.  You are responsible for required periodic maintenance or service, to include changing or cleaning of air filters
and lubrication or cleaning of components.  Failure to properly install, operate or provide maintenance per the instructions will void the warranty.

Warranty Begins

The warranty period begins when the installation is complete and the product is ready to operate.  You must be able to verify this date
whenever a warranty claim is made.  Original bill of sale, installer’s invoice or other similar document will suffice.  If the beginning date
cannot be verified, we will consider warranty coverage to begin 6 months after the date the product was shipped from our factory.

Limitations on Implied Warranties

Implied warranties of merchantability or, to the extent applicable, fitness for a particular purpose are limited to 5 years, the same duration
as the basic limited written warranty provided herein.  Some states/provinces do not allow limitations on how long an implied warranty of
merchantability or fitness lasts, so the above limitations or exclusions may not apply to you.

Only Warranty

This written Limited Warranty is the only warranty made by the warrantor;  this warranty is in lieu of and excludes all other warranties,
express or implied.  The warrantor does not authorize any person to provide any other warranty or to assume for it any further obligation in
connection with the warranted product.

These Warranties Apply Only:

To products in their original installation location and become void upon re-installation.

To units installed with indoor coil combinations listed in the Air-Conditioning and Refrigeration Institute (ARI) Directory of
Certified Unitary Equipment. (www.aridirectory.org)

What is NOT Covered

1. Cabinets or cabinet pieces.
2. Normal maintenance items such as filters, fan belts, fuses or other consumable items.
3. Damage caused by flood, wind, fire, lightning, mold, failure to maintain properly, accidents or misuse, including operation of

electrical equipment at voltages other than the range specified on the unit nameplate (includes damages caused by brownouts).

4. External wiring, piping, venting or attachment of accessory products not integral to our product, including without limitation,

humidifier, air cleaner, vent damper, thermostat or other mechanical devices not manufactured by the warrantor.

5. Products that have been operated in a corrosive atmosphere where a concentration of acids, halogenated hydrocarbons or

other corrosive elements (such as chlorine, fluorine, salt, recycled waste water, urine, fertilizers, or other damaging sub-
stances or chemicals) causes deterioration to metal surfaces or integral components.  NOTE:  Operation in a corrosive
atmosphere is considered abuse and voids this warranty.

6. Products that have NOT been installed in accordance with our published installation instructions, applicable local, state/

provincial or national codes, ACCA published standards.

7. Products that have NOT been installed by competent, qualified installers.
8. Products that have been moved from their original place of installation.

Warranty on Replacement Components

Any replacement component furnished by us will assume the remaining (unused) portion of the Limited Warranty.

Consequential Damages

The warrantor shall not be responsible for any consequential damages caused by any defect in the product.  Some state/provinces do not
allow the exclusion or limitations of incidental or consequential damages, so the above limitation or exclusion may not apply to you.
