MUST READ-ATTENTIONS AND WARNINGS
1. Be sure to hire only one certified, licensed HVAC Company to complete 100% of the installation so that all
details of the installation are clear, complete and well taken care of.
2. Be sure to have ONLY the licensed HVAC professional perform all parts of the installation. Factory Warranty
will be lost if any portion of the installation is not performed by licensed HVAC contractor. DIY or partial DIY will
void ALL factory warranties. One example of partial DIY would be calling the HVAC technician to release
refrigerant or the sort while other installation has or is to be conducted by non-HVAC technician.
3. With hiring a technician that is offering their services as a "side job" and not through their licensed HVAC
company may pose a possible risk of an incomplete or unsatisfactory installation of no guaranteed
workmanship and lack of further service, if needed.
4. Have the installing technician read in full the installation manual of the product model you have. Some details
may vary and some may be the key to determine the success and quality of the installation. Experience with
certain manufacturer may not be applied fully to another manufacturer. For example, wiring, refrigerant
adjustment and trial testing procedures may differ from manufacturer to manufacturer and model to model.
Any ignoring or negligence may cause unit failure or damage which could be irrevocable and permanent.
5. All of YMGI's products are fully tested and have passed rigorous safety and performance standards and others
related to the industry, before being packed and shipped. YMGI only uses famous brands as suppliers for their
parts that are also known for their high quality and performance. The quality of the installation plays a key role
as much as up to 90% importance in your unit's overall performance and lifetime. A poor installation can result
in unit failure and inefficiency either immediately or over a period of time.
6. Some licensed contractor/technician may make mistake some time. YMGI doesn't supervise nor be able to
control their installation. It is a key whether your unit will work properly that the installing technicians take each
variable into account in each installation and well take care of all the details, from very beginning to end, during
the initial installation, completely and professionally.
ATTENTIONS
The following will cause damage to the unit and key components
factory
warranty. Below are details that may be missed at the time installation but will eventually over time cause
unit failure:
and the loss of your unit's
1. Any foreign substances introduced into the system as a result of failure of not sealing the ends of the
refrigeration piping before pulling through structures at time of installation.
2. Not installing an oil P-trap in the suction copper line where indoor unit is located 18' or more below the outdoor
unit.
3. Cross piping and/or cross wiring on 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 soap bubble testing.
5. Not conducting a negative leak check by evacuating the copper lines for 30 minutes. Vacuum must be held at
500 micron or better for at least 5 minutes, starting from 5 minutes after the vacuum pump is shut off.
6. Not conducting a positive leak check prior to the negative leak check.
7. Not selecting the correct size of wire or circuit breaker.
8. Not answering ALL questions in the technician's checklist inside the warranty registration form.
1. Any kinks or improper bending of the copper piping.
2. Any improper flaring or not centering of the flare with the nut, or not tightening any connection.
3. Not trial testing each indoor unit individually.
4. Not reading technical data (temp/time/pressure/current) after the system is stabilized (normally compressor
needs to work at least 10 minutes). Data read too early may lead to inaccurate or false judgment or even a
false sense of security.
In an effort to protect our customers from any possible faulty installation which can lead to premature unit failure,
we like to provide the above information to you in addition to the technician. You can the judge by yourself and
observe while your system is being installed, though your observation may not be treated as any guarantee or
witness whether your system would be installed properly and professionally. If at any time you feel that there
may be an installation issue, please have your technician contact YMGI at (866)833-3138 x 703 to clear your
questions.
The following may be overlooked or ignored as not a problem but actually will cause your unit to
underperform or even cause unit failure eventually.
