Introduction
Read this manual carefully, making sure you understand all the instructions, practices and procedures contained in this manual.
Be sure you are familiar with all the safety advisories that appear throughout this manual. Your personal safety depends upon
your observance of all precautions contained in this manual.
Safety advisories appear throughout this manual and your personal safety and the proper operation of this appliance depend upon
the strict observance of these precautions.
The 3 types of advisories are defined in the following table:
Indicates a potentially hazardous situation which if not avoided could result in serious
injury or even death.
Indicates a potentially hazardous situation which, if not avoided, could result in minor or
moderate injury. It could also be used to alert against unsafe practices.

Important Environmental Concerns
Studies have shown that certain man-made chemicals can affect the earth’s stratospheric ozone layer when released into the
atmosphere. Refrigerants that contain Chlorine, Fluorine and Carbon (CFCs) and those containing Hydrogen, Chlorine, Fluorine
and Carbon (HCFCs), may affect the ozone layer. Not all refrigerants have the same potential impact on the environment. YMGI
Group advocates for the responsible handling of all refrigerants including industry replacements for CFCs such as HCFCs and
HFCs.
Responsible Refrigerant Practices
YMGI Group believes that responsible refrigerant practices are important to our customers, the HVAC/R industry and the
environment. All HVAC/R technicians who handle refrigerants must be certified. The Federal Clean Air Act (Section 608) sets
forth the requirements for handling, reclaiming, recovering and recycling of certain refrigerants, theequipment and tools necessary
to perform these service procedures. In addition, some states or municipalities may have additional requirements that must also
be adhered to for responsible management of refrigerants. HVAC/R technicians must know the applicable laws and follow them.
Disposal Notice
Do not dispose this product or its components as unsorted municipal waste, as they contain items that may require special
treatment. Contact your local waste management company for details.
Proper Field Wiring and Grounding Required!
Failure to follow established electrical codes can result in death, serious personal injury and property damage. All field wiring
MUST be performed by qualified personnel. Improperly installed and grounded field wiring poses FIRE and ELECTROCUTION
hazards. To avoid these hazards, you MUST follow the requirements for field wiring installation and grounding as described in
this manual and by NEC and your state and local electrical codes.
Personal Protective Equipment (PPE) Required!
Failure to wear proper PPE for the job being undertaken could result in serious injury or even death. Technicians must take the
necessary precautions to protect themselves from potential electrical, mechanical, and chemical hazards and MUST follow all
precautions in this manual and on the tags, stickers, and labels, as well as the instructions below:
•Before installing or servicing this unit, technicians MUST put on all PPE recommended for the work being undertaken.

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: [phone] or Email: [e-mail]
IMPORTANT: YMGI Group is the MEDIA AUTHORITY:
YMGI Group, located in O'Fallon, MO, is the author of all media produced for its products and is the only party able
to give any additional explanation for any data, definitions and or descriptions found within any of its media, including
but not limited to YMGI product brochures, manuals, pamphlets, catalogs, and videos. YMGI's distributors, installers,
dealers, agents, customers or any other third parties will not supersede YMGI in anyway concerning YMGI-published
materials and their meaning. Any concerns or questions arising from YMGI distributors, installers, dealers, agents,
customers or any other third parties, should be presented directly to YMGI. YMGI will respond to any concerns or
questions, if necessary, about any of its media in writing.

Be sure to only hire a certified and currently licensed HVAC Company to complete 100% of the installation so
that all details of the installation are performed correctly and completely.
Be sure to have ONLY the licensed HVAC professional perform all aspects of the installation. Factory Warranty
will be void if any portion of the installation is not performed by a licensed HVAC contractor/technician. DIY or
partial DIY will also void ALL factory warranties.
When hiring an HVAC technician that is offering their services as a "side job" and not hiring a licensed HVAC
company may pose possible risk. This may result in an incomplete or unsatisfactory installation, no guarantee
for workmanship and lack of maintenance and further service to your unit.
Have the installation technician read in full the installation manual and all supplied documents for the product
model you purchased. Details within the documentation contributes greatly to the success and quality of the
installation. Experience with other manufacturers may not be applied fully to another manufacturer, although
there will be similarities there will also be differences. Ignoring the provided installation procedures is an act of
negligence and may cause unit failure or damage which could be irrevocable and permanent.
It is possible for a licensed contractor/technician to make a mistake during the installation. YMGI doesn't
supervise nor is able to control the contractor/technician’s installation. It is critical that the installer take each
variable into account during the initial installation. This will ensure a complete and professional
installation and that all units work properly.
The following will damage the unit and its key components resulting in loss of factory warranty:
1. Any foreign substances introduced into the system because of failure to seal the ends of the refrigeration piping
before pulling the piping through any structures at time of installation.
2. Not installing an oil P-trap in the copper suction line where the indoor unit is located 18 feet or more below the
outdoor unit.
3. Cross piping and/or cross wiring of any units including more than one single zone or a multi zone system.
4. Not conducting a positive leak check by charging the system with dry-nitrogen and performing soap bubble
testing.
5. Not conducting a negative leak check by evacuating the copper lines for 30 minutes. Vacuum must be held at
500 microns or better for at least 5 minutes, starting 5-minute timer after the vacuum pump is turned off.
6. Not conducting a positive leak check prior to the negative leak check.
7. Not selecting the correct size wire or circuit breaker.
8. Not answering ALL questions in the technician's checklist located inside the warranty registration form.
The following may be overlooked, ignored, or considered unimportant during your installer's installation, but
will cause your unit to underperform and may cause unit failure.
1. Any kinks in or improper bending of the copper piping.
2. Any poorly formed flares or not centering the flare with the flare nut, or not tightening all connections.
3. Not trial testing each indoor unit individually.
4. Not reading technical data (temp/time/pressure/current) after the system is stabilized (normally the compressor
needs to run at least 10 minutes before reading the data). If the data is read too early may lead to inaccurate
assessments about the unit.
In an effort to help protect our customers from possible faulty installations that can lead to premature unit failure,
YMGI provides the above information for you and the technician. You can observe while your system is being
installed, even though your observation is not a guarantee your system is being or has been installed properly and
professionally. With the information provided above, you will know some things to look for and questions you can
ask. If at any time you feel there may be an issue with the installation, please have your technician contact YMGI at
[phone] x 703 with any questions, issues or concerns you may have.

OUTDOOR GRILLE
An outside grille must be installed to direct air flow for proper unit operation and also the outdoor coil
protection. The grille must be installed before installing the chassis.
When replacing an old chassis with an existing grille or using a specialized grille in a new installation, please
contact a technician or engineer and confirm that the new chassis can be used with the non-standard
specialized grille. An improper outdoor grille may cause poor cooling or heating effect, a higher power input
and shorten the unit service life and possibly void the warranty.
CHASSIS INSTALLATION
1. Remove front grille. See Fig A.
The front grille can be removed for more thorough cleaning or to make the model and serial numbers
accessible. Open the panel and remove the two grille screws can remove the grille.
Pull the grille out from the bottom and lift up from the tabs on the top of the case.
