YMGI, Engineered Comfort Products for A Sustainable and Efficient Green World !

LIMITED PRODUCT WARRANTY POLICIES

The YMGI products are designed and manufactured free from defects in workmanship, and materials for normal 
use. However, for any reason, including many handlings and occasions between the YMGI factories/warehouses 
and where you receive the products, the unit doesn't work, YMGI Group will help to remedy the occurrence in the 
following warranting ways:  

Compressor: 

YMGI will warrant the compressor of YMGI-validated and approved warranty filing, for a period of 

5 years from the date of successful installation at original location.

Parts: 

YMGI will warrant parts of YMGI-validated and approved warranty filing, for one year from the date of 

successful installation at original location.  

All warranty compressors and parts replaced will become the sole property of YMGI Group and must be returned 
to YMGI Group upon request.  Warranty parts may be new or refurbished. All parts are tested and approved 
before shipping.

At no time does the YMGI Group warrant labor cost of any type. Warranty will start from the date of 
successful installation at initial location, or 90 days as of original shipping date from YMGI Group, 
whichever comes first.
This is a standard warranty of limited liability and DOES NOT cover the following:

* Any damage or repairs to properties, or persons as an incident or consequence of improper or faulty 
  transportation, installation, operation, maintenance or service.
* Damage caused by frozen or broken water hoses or refrigeration pipes in the event of equipment failure.
* Any damage as a result of floods, fire, wind, lightening, accidents, corrosive atmosphere or any other conditions 
  beyond the control of YMGI Group.
* Any damage due to interruption or inadequate electrical service to equipment.
* Any products that are installed outside the US or Canada.
* Any unit that has been moved from the original installation address.
* Any labor costs associated with the installation or service of the unit.
* Poor unit performance due to improper unit selection (SEER, Unit size).

To validate the above warranties, ALL the following conditions must all be fulfilled:

1. The unit was fully (100%) and successfully installed by licensed or certified HVAC technicians.
2. The unit was installed following all NEC, state and local codes.
3. The unit was installed following all instructions and manuals made by YMGI Group.
4. ALL fields, especially the technician-checklist, of the 

Limited Warranty Registration Card/Form

 were filled 

    completely by the installing technician and signed by both the installing company technician and the unit owner.
5. The 

Limited Warranty Registration Card/Form

 and a copy of the original installing company's invoice had 

    been received by YMGI Group-Warranty Dept., POB 1559, O'Fallon, MO 63366, within 7 days of successful 
    installation.

No warranty filing will be validated or approved, if any one of the above 5 conditions is not met.
Product registration doesn't guarantee the validity of this limited warranty statement.

Steps to follow for warranty part replacement:

1. Installing or service technician contacts YMGI tech support at 1-866-833-3138 ext 703 from the jobsite, to 
    double-check and confirm with YMGI Technical support the exact part(s) needed to fix all the problems.
2. YMGI will check the customer's warranty filing. Parts for validated and approved warranty will not be charged. 
    Parts of invalid warranty filing or unapproved warranty requesting, will be charged accordingly.
3. YMGI will ground ship out the parts ASAP. Expedited shipping is available at the customer's cost.
4. Replacement parts of approved warranty registration are to be warranted for the remainder of the 1 year parts 
    and 5 year compressor warranty. Purchasing of replacement parts of invalid warranty filing or unapproved 
    warranty requesting, will be as they are and bear no warranty.

YMGI keeps on improving products with various engineering changes without prior notice.  Such improvements 
or changes include but not limited to product specification, appearance, functions, sizes, packaging and others.  
These improvements or changes will not void the limited warranty stated herein. YMGI keeps the final explanation 
of this warranty policy.
