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 does NOT 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: 
 

Toll Free Number: (866)833-3138 or Email:
