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.
