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.
