The cost of not having your unit installed properly can be more expensive than spending the little extra money
that hiring the right contractor will cost. Protect your investment and warranty eligibility by doing it right the first
time.
THE FOLLOWING LISTS THE JOBS AND RESPONSIBILITIES OF THE
TECHNICIAN/ CONTRACTOR:
* Performing a load calculation for the room(s) you would like to air condition. Cooling requirements will be
different from the heating requirements. They will consider cooling hours, heating hours and your special needs
or requirements. Supplemental heating such as baseboard heater or portable heater may help you save money
by not over-sizing or under-sizing the heating equipment.
* Selecting the right type, size or model of cooling and/or heating equipment.
* Determining the best location to install the unit. (Positioning indoor unit, outdoor unit and running the inter-
connecting pipes/wires.)
* Selecting the correct electrical components (HVAC circuit breaker or fuse and disconnect switch for the electric
power to the outdoor unit, types and sizes of the connecting wires between circuit breaker/disconnect switch
and outdoor unit, and the wires between outdoor unit and indoor unit).
* Keeping the indoor unit away from the ceiling and the outdoor unit away from the wall, bushes and other
obstacles at a proper and safe distance to allow for the proper airflow through the unit's.
* Placing the units on a secured level structure.
* Taping and sealing both ends of the inter-connecting pipes, before running them through structures, to prevent
dust or other debris from getting into the pipes otherwise they will contaminate and damage the refrigeration
system. Failure to follow this practice will make your factory warranty void.
* Connecting the inter-connecting pipes between the outdoor and indoor units. Checking for leaks through
pressurization with nitrogen. After releasing nitrogen, evacuate the piping and indoor unit, for removal of system
contaminants. Finally refrigerant introduction and adjustment, if necessary, from the outdoor unit.
* Back-seating the stopping valves at outdoor condensing unit to release pre-charged refrigerant from outdoor
unit to indoor unit.
* Measuring and recording the electrical voltages at different terminals and the refrigerant pressures at stopping
valves of outdoor condensing unit.
* Verifying and ensuring the unit is connected to the proper electrical power supply.
* Adjusting refrigerant levels (if necessary) following the installation instructions or chart on the unit.
* Checking for any unusual noises and other abnormalities that might be present.

QUESTIONS ABOUT SELF-INSTALLATION VS HIRING LICENSED HVAC
TECHNICIANS
Does YMGI allow to do-it-yourself installations (DIY) partially or fully? NO.
Unfortunately no brand or manufacturer can take the responsibility of the equipment if it is not professionally
installed by a currently licensed HVAC technician/ contractor.
If unit is installed by non-licensed people, in part or fully, will the factory warranty be void? YES.
Some DIY installations have been successful, but these are exceptions. Most have resulted in equipment failure,
due to lack of knowledge and experience. A few of the problems result from DIY's lack of knowledge in the
following areas:
* Sizing and selecting correct type, size and model of cooling and/or heating equipment.
* Sizing and installing correct electric circuit breakers and wires.
* Wiring the units correctly and properly.
* Taping the ends, connecting to indoor and outdoor units correctly and properly.
* Vacuuming the inter-connecting refrigerant lines.
* Checking and/or fixing the refrigerant leaks.
* Checking and/or fixing the condensate drain leaks.
* Releasing the refrigerant from outdoor unit to indoor unit.
* Running the unit to check all the unit functions.
* Conducting the installation or trouble-shooting with correct tools, experience or professional knowledge to
correct the problem.
RECEIVING AND FREIGHT DAMAGE
ATTENTION
* Freight (package/unit) shall be checked thoroughly for damage at receiving before accepting by signing on the
carrier's delivery paperwork.
* Upon shipment being signed for acceptance, it becomes a binding document as to the condition of the products
on delivery. We cannot process any shipping damage claim, if you accept the delivery.
* If damage is found at delivery, both you and the delivery driver must make notes on the delivery receipt or other
freight paperwork detailing the damage found by marking position/parts on unit, description of damage, time/
date, your name, contact phone, etc. on the delivery documents. Make a copy of the marked delivery receipt.
