IMPORTANT NOTES
SAFETY CAUTIONS AND ALERTS
Installation, Operation, Maintenance, and Service shall follow professional standards and practices for
conventional cooling and heating equipment, under International, National, State, City or Local Codes, and follow
guidelines listed in all related manuals and associated product information provided directly, from YMGI. Failure
to adhere to proper Installation, Operation, Maintenance, and Service could result in unit malfunction damage to
equipment, personal property, or physical injury, or even death, which YMGI is not responsible for.
Installation must be performed following the
YMGI Installation/Maintenance Manuals.
Installation must be performed by a certified
technical installer only.
DO NOT attempt to install
the unit by yourself trying to save money.
Do-It-
Yourself (DIY)
installation will void YMGI provided
warranty and could result in injury or death, or
property damage due to fire, electrical shock, leaking,
collapsing, which YMGI is not responsible for.
Install the unit onto a strong load bearing
structure
. The location must be capable of handling
the weight load of the unit to prevent the unit from
falling or causing injury.
Attach both the indoor and
outdoor units to the brackets that are fixed to the
right position securely.
Only use manufacturer specified and codes
allowed wires and conduits to connect to the
units so the stress is not applied to the sections.
Incomplete connecting and insecure fixing could
cause fire or damage.
Wiring must conform to national regulations
.
Failure to adhere to these standards could result in
personal injury or death or property damage due to
fire, electrical shock, falling units, or leaking.
Connect the power cord directly to a designated
and exclusive AC Power Circuit Breaker and or
Disconnect Switch.
The circuit must exceed
permissible currents and is free of insulation and
contact defects. Shall refrain from intermediate or
multiple connections to avoid fire or electric shock.
DO NOT supply power until all wiring and tubing
is checked completely.
Double check for gas leaks during or after
installation.
The refrigerant gas may cause harmful
substances when subjected to heat or fire.
Refrigerant leakage will cause unit not to generate
enough cooling or heating and even damage
compressors and other parts.
Shut off the main power prior to and during
installation to avoid electrical shock.
Make sure
that the electrical power is disconnected from the
unit by making a notice or put a sign at the power
switch panel, to keep other people from setting the
power back during installation.
Connect all wiring securely.
Any loose wire or other
bad contact may cause an electrical arc, overheating,
or fire hazard. Make sure that the unit is grounded
following YMGI Instructions and NEC, International,
State, City, and Local Codes. Electrical cover shall be
securely attached to the indoor and outdoor unit
service panels, otherwise, could result in fire or
electric shock due to accumulation of dust, sediments,
water, moisture, etc.
Only use authorized YMGI parts in the
installation, maintenance, service, and repair of
YMGI units.
The use of non-authorized or
defective parts will void the warranty and could
cause injury or death or property damage due to
water leakage, falling units, fire, electric shock, etc.
Pay extreme caution to interconnecting
refrigerant copper tubing, when installing or
relocating the unit.
Make sure that no other
substance than the specified refrigerant enters the
refrigeration circuit. Any presence of foreign
substances such as air or water or moisture can
cause an abnormal pressure rise or overheat, which
will result in an inefficient unit performance or unit
malfunctions, and will shorten unit lifetime.
Pay extreme caution to interconnecting
refrigerant copper tubing when installing or
relocating split system, as applicable.
1) Make sure that no substance other than the
specified refrigerant enters the refrigeration circuit.
Any presence of foreign substances such as air or
water or moisture can cause an abnormal
pressure or overheat which will result in an
inefficient unit performance or unit malfunction and
will shorten the longevity of the unit.
2) Tape two ends of the copper tubing, tape the
wires for the corresponding indoor
unit to the copper tubing, and mark well with either
A, B, C or D to identify each copper tubing/wiring
bundle. Do not cross wire or mismatch tubing
among indoor units of the multiple zone systems.
Connect the electrical wiring and copper tubing
from each zone of indoor unit to the corresponding
wiring and copper tubing connections of the
corresponding outdoor section (at outdoor
condensing unit). Failure to do so will cause unit
malfunctions, or damages to the compressors and
other parts in the unit and even property or
personal injuries.

correctly.
* Customer do-it-yourself (DIY) installation caused and/or will cause trouble to the unit and your property and
yourself.
* YMGI doesn’t allow nor recommend nor honor warranty for DIY installation. Customers take full responsibility
for DIY installation.
* DIY installation may save money up front, but will cost you more money and headaches down the road.
