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.

The quality of the installation plays a key role in whether the units will work well and for an extended period of
