If you have any questions about your unit or even doubt if the unit has any problem, you can first check against 
the mannds. If you can not find answers, then you can contact your local installer or service technician to 
physically inspect the unit.  If at the time of inspection the installer or service technician have any questions they 
can contact YMGI technical support division directly at:

Dear Customer(s)/End User(s)/Unit Purchaser(s)/Installer(s)/Contractor(s):

Thanks for choosing YMGI products.

The YMGI equipment you purchased is either a split-type or a self-contained cooling/heating system which 
requires an installer's license, certification, knowledge, experience, carefulness and details for a successful and 
good installation. This equipment is different from those window or portable air conditioners you can normally 
purchase from local retail stores such as Home Depot, Lowe's, Sears, etc. which the manufacturer may not 
require licensed personnel to install. 

Reading and following the YMGI Group's recommendations, suggestions, and requirements, written in the 
following pages and other documents, is the first step to ensuring a smooth and trouble free installation & proper 
operation of your products for many years to come.

YMGI Group, POB 1559, O'Fallon, MO 63366 is the only party who holds the final explanation (in authorized 
writing) about any descriptions or data in YMGI-published materials, including but not limited to 
YMGI product brochures, manuals, pamphlets, catalogs, videos and any other media. YMGI's distributors, 
installers, dealers, agents, customers or any other third parties shall not supersede YMGI to make any 
explanation about what YMGI-published materials mean. Any uncertainty or questions, arising from YMGI 
distributors, installers, dealers, agents, customers or any other third parties, should be passed directly to YMGI 
for an explanation in writing.

IMPORTANT NOTE-YMGI HOLDS FINAL EXPLANATION:

The quality of the installation plays a key role in whether the units will work well and for an extended period of 
time. The information we provide in our manuals is for the sole purpose of reminding you and your installer.

It is our ultimate goal to help insure that your YMGI units are installed properly and correctly from the very 
beginning to the very end. This ensures that your YMGI units will work well and not only provide a comfortable 
room but also peace of mind.   

YMGI doesn't recommend nor allow any do-it-yourself (DIY) installation (partially or fully), since DIY will cause 
problems sooner or later to your units and your upfront saving is Not saving down the road.

YMGI warranty doesn't cover any DIY units.

P1 OF 36
