Warnings and cautions
Warnings and Cautions. Notice that warnings and cautions
appear at appropriate intervals
throughout this manual. Warnings are provided to alert
installing contractors to potential hazards that could result
in personal injury or death, while cautions are designed to
alert personnel to conditions that could result in
equipment damage.
Your personal safety and the proper operation of this
machine depend upon the strict observance of these
precautions.
Attention: Warnings and Cautions appear at appropriate
sections throughout this literature. Read these carefully.
WARNING: Indicates a potentially hazardous situation
which, if not avoided, could result in death or serious
injury.
CAUTION: Indicates a potentially hazardous situation
which, if not avoided, could result in minor or moderate
injury. It may also be used to alert against unsafe practices.
NOTICE: Indicates a situation that could result in
equipment or property-damage only accidents.
Trane has always recommended installing Trane approved
matched indoor and outdoor systems.
The benefits of installing approved matched systems are
maximum efficiency, optimum performance and best
overall system reliability.
WARNING
This equipment is to be serviced by professionally
trained personnel ONLY. Under NO circumstances
should an unqualified person service it. This
equipment contains refrigerant under PRESSURE
and operates at HIGH OLTAGE. Improperly installed,
adjusted or altered equipment by an unqualified
person poses safety hazards including FIRE,
ELECTROCUTION, or EXPLOSION, which could
result in death or serious injury.
WARNING
Electrocution and Fire Hazards with Improperly
Installed and Grounded Field Wiring!
Improperly installed and grounded field wiring
poses FIRE & ELECTROCUTION hazards. To avoid
these hazards, you MUST follow requirements for
field wiring installation and grounding as described
in the National Electrical Codes (NEC) and your
local/state electrical codes. All field wiring MUST
be performed by qualified personnel.

Failure to follow these requirements could result in
death or serious injury.
WARNING
R410A Refrigerant under Higher Pressure than R22!
The units described in this manual use R410A
refrigerant which operates at 50 to 70% higher
pressures than R-22. Use only R-410A approved
service equipment. Refrigerant cylinders are
painted with "pink" color to indicate the type of
refrigerant and may contain a "dip" tube to allow for
charging of liquid refrigerant into the system. For
specific handling concerns with R-410A, please
contact your local Trane representative.
Failure to use R-410A approved service equipment
could result in standard equipment exploding under
R-410A higher pressure which could result in death
or serious injury.
NOTICE
Use PVE Oil with R-410A Mini-Split Units!
All R-410A mini-splits use a PVE oil (Polyvinyl Ether
Oil) that readily absorbs moisture from the
atmosphere. To limit this "hygroscopic" action, the
system should remain sealed whenever possible. If
a system has been open to the atmosphere for more
than 4 hours, the compressor oil must be replaced.
Never break a vacuum with air and always change
the driers when opening the system for component
replacement. For specific handling concerns with
PVE oil, contact your local Trane representative.
USE ONLY THE FACTORY RECOMMENDED - DAFNE
HERMETIC OIL FV50S - for servicing these units.
Important!
Environmental Concerns
Scientific research has shown that certain man-made
chemicals can affect the earth's naturally occurring
stratospheric ozone layer when released to the
atmosphere. In particular, several of the identified
chemicals that may affect the ozone layer are refrigerants
that contain Chlorine, Fluorine and Carbon (CFCs) and
those containing Hydrogen, Chlorine, Fluorine and
Carbon (HCFCs). Not all refrigerants containing these
compounds have the same potential impact to the
environment. Trane advocates the responsible handling of
all refrigerants—including industry replacements for CFCs
such as HCFCs and HFCs.
