If any part of your Marvair

®

 Heat Pump or Air Conditioner fails because of a manufacturing defect within

fifteen months from the date of original shipment by Marvair or within twelve months from the date of original
start-up, whichever is the earlier date, Marvair will furnish without charge, EXW Cordele, Georgia, the required
replacement part and pay for the related service labor to replace the failed part. The owner must provide proof
of the date of the original start-up. The owner’s registration card filed with Marvair, the contractor’s invoice,
the certificate of occupancy or similar document are examples of proof of the date of the original start-up.

When service is required, it must be performed during normal working hours (8:00 a.m. to 5:00 p.m.)

Monday through Friday and must be performed by Marvair

®

 personnel or their designated Service

The responsibility of the Owner of the Equipment includes the following:

1.

To operate the equipment according to the manufacturer's instructions.

2.

To provide easy accessibility for service.

3.

To check and reset circuit breaker(s) and disconnect before calling for service. (Circuit
breaker(s) may
be in the main service panel. The disconnect is in the Marvair

®

 unit.)

4.

To keep the unit clean and free of dirt.

5.

To replace filters as required. (Filters are located in the lower front panel of the Marvair

®

unit below the
indoor blower section.)

6.

To keep the outdoor coil section clean and free of leaves, paper, etc.

7.

To pay the charges incurred when any of the above have not been done.

8.

To pay for repair or replacement of any material or part other than those within the
Marvair

®

 unit or

thermostat itself.

In addition, if the hermetic compressor fails because of a manufacturing defect within the second through

fifth year from the date of original shipment by Marvair

®

, Marvair will furnish without charge, EXW Cordele,

Georgia, the required replacement.  Any transportation, related service labor, diagnosis calls, filter, driers and
refrigerant are not included.

The owner of the product may ship the allegedly defective or malfunctioning product or part to Marvair

®

,

at such owner’s expense, and Marvair will diagnose the defect and, if the defect is covered under this warranty,
Marvair will honor its warranty and furnish the required replacement part.  All costs for shipment and risk
of loss during shipment of the product or part to Marvair and back to the owner shall be the responsibility
and liability of the owner.  Upon written request by an owner, Marvair may arrange for remote diagnosis of
the allegedly defective or malfunctioning product or part but all costs for transportation, lodging and related
expenses with regard to such diagnostic services shall be the responsibility and liability of the owner.

An owner requesting performance under this Warranty shall provide reasonable access to the allegedly

defective or malfunctioning product to Marvair

®

 and its authorized agents and employees.

This warranty only applies to products purchased and retained for use within the U.S.A.  This warranty

does not cover damage caused by improper installation, misuse of equipment or negligent servicing.
