Note From YMGI 

– Must Read 

 

Dear Customers, Purchasers, Installers, and Contractors 

 

Thank you for choosing a YMGI product. 

 

All YMGI's products are fully tested and have passed rigorous safety, performance and manufacturing standards before 
being packed and shipped. YMGI only uses suppliers that meet our strict standards for high quality and performance for 
all parts. YMGI also recognizes a quality installation is equally important therefore your system must be installed by a 
licensed HVAC professional. A quality installation ensures your unit will operate at its highest efficiency and peak 
performance for many years of worry free comfort; while a poor installation can result in unit failure and cause the unit to 
operate inefficiently, either immediately or over time, resulting in costly repairs.  

 

Because a quality installation is so critical, YMGI provides detailed information in our manuals which will aid the installing 
technician and the owner of the unit(s). 
 
At YMGI our goal is to ensure that your YMGI units are installed properly and correctly from the beginning.  
 
The  YMGI  equipment  you  purchased  is  either  a  split-type  or  a  self-contained  cooling/heating  system.  These  types  of 
systems require a certified and licensed HVAC professional technician for proper installation. Only a certified and licensed 
HVAC  professional  technician  will  have  the  knowledge,  experience,  and  attention  for  all  required  details  to  perform  a 
complete and successful installation. This equipment is different from a window or portable type air conditioners you can 
purchase from local retail stores such as Home Depot, Lowe's, Sears, etc. which the manufacturer may not require certified 
and licensed personnel to install. 

 

Reading and following YMGI Group recommendations and requirements contained in the following pages and other 
documents, is the first step to help ensure a smooth installation and proper operation of your unit for many years. 
 

 

YMGI doesn't recommend nor allow any do-it-yourself (DIY) installation (partially or fully). Due to the complexity of the 
installation of this product most DIY installations usually have problems, either immediate or near future. These problems 
can cost more to fix than any upfront savings. 

YMGI warranty doesn't cover any DIY units. 

 
If you have any questions about your unit or if the unit has a problem, you should first check the manual. If you can’t find a 
solution, then contact your local installer or service technician to schedule a service appointment. The technician can 
physically inspect the unit. If at the time of inspection, the installer or service technician has any questions about the unit, 
they can contact YMGI technical support division directly at:
