MUST READ-2

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

* 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.

CUSTOMER AND TECHNICIAN MUST READ

* If the damage is minor or partial, that you choose to accept, you can contact the distributor or YMGI to discuss 
  the possible replacement of the damaged part.
* If refusal of the shipment

 

is needed due to severe freight damage, 

DO NOT

 sign the carrier's delivery receipt 

  document indicating that you accept the products.  Mark receipt "REFUSED DUE TO FREIGHT DAMAGE." 
  Sign and date along with the delivery driver's signature and date.
* Take pictures showing the damage, before the delivery driver leaves.
* If you accept the delivery or fail to note damage on the driver's delivery receipt, the ability to claim freight 
  damage is lost and YMGI will not replace the unit on this basis.
* Contact the distributor or YMGI, report the damage by forwarding the marked delivery receipt copy and pictures.
* Only after YMGI verifies with the carrier the necessary detailed notes of received freight damage, will the 
  damaged products be eligible for replacement.
* If the returned products are found not damaged, YMGI will treat it as a return and will charge you 25% of 
  product value plus added shipping cost.

2) You will follow what is written hereafter in this and other documents that we publish.

3) You will be bound by and completely follow all policies, guidelines, instructions, warnings, attentions and other 
    materials, as published by YMGI Group, its subsidiaries or sister companies, in writing. 

4) Only a successful installation, fully (100%) conducted by a qualified HVAC technician(s), as detailed in the 
    checklist of the 

Limited Product Warranty

 

Policy

 and 

Limited Product Warranty Registration Card/Form

    along with a properly detailed installation invoice, is eligible for the 

Limited Product Warranty

.

5) Failure to follow what is written hereafter may cause various equipment issues that you will take full 
    responsibility and liability for, including, but not limited to, losing manufacturer's warranty, unit not working 
    properly, unit malfunctions, under-performance, decreased safety, increased potential of various damages to 
    your property, body, home and/or business, etc.

6) YMGI documents and policies supersede those made or provided by the sales distributors or installing 
    contractors. YMGI Group maintains the final authority in explaining and resolving any and all discrepancies 
    that might exist between distributors/contractors' documents and ours. 

YMGI STRONGLY RECOMMENDS:

* Customer hires a currently licensed/ certified HVAC technician(s) (N.A.T.E. or A.C.C.A certification is strongly 
   recommended) to conduct 100% of the installation, inspection of all unit functions and repair service.

* Customer signs an installation/service contract with the installation/service technician's company who has good 
   service references and you trust. Installation and service is very important to the life of your investment and 
   provide you a lifetime of comfort

 

and peace of mind.

* Customer requests the installer to put down a1-year labor warranty coverage in the installation contract.

* Have the technician check against all the items in the checklist of the 

Limited Product Warranty

 

Registration 

   Card/Form

, sign and date it, to help ensure a proper and professional installation.

* Customer pays in full, only after all the unit functions are inspected, the unit works properly, warranty checklist 
   is fully filled out and signed and you are fully satisfied.

* If any unit abnormality is found, have your technician check the unit first. Have them call for manufacturer 
   technical assistance, if necessary, from your job site, not his office, so that we can more accurately assist him 
   in diagnosing the cause of the malfunction.

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.

UPON PURCHASING, OPENING PACKING BOXES AND INSTALLATION OF 
YMGI UNITS/ACCESSORIES, YOU AND TECHNICIANS YOU HIRE TO 
INSTALL THEM ARE ASSUMED TO HAVE READ ALL MATERIALS AND 
AGREE TO FOLLOW AND BE BONDED BY ALL WE SAY IN YMGI MANUALS. 

11) If all the suggestions have been taken and all the necessary steps are followed.

12) If the contractor(s)/technician(s) are experienced with the systems/brands you purchase.
      

You might spend less. But remember, many times you get what you pay for.

13) Sign a contract with them. The contract should list all the detailed work they will conduct and the standards 
      they will follow. Some contractors are willing to include a 1-year installation/service warranty at no extra 
      charge. Check with them to see if that is available. If available, include that in the contract. 

14) Verify and confirm the installation is done completely and all the unit functions have been checked and are 
      working properly, all the items in the checklist have been checked and marked well in the warranty registration 
      card/form, prior to paying the contractor in full.

The cost of not having your unit installed properly can be more expensive than spending a little extra money 
that hiring the right contractor will cost. Protect your investment and warranty eligibility by doing it right first time.
