Warnings and Cautions.
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 depends upon the strict observance of these
precautions.
Read this manual thoroughly before operating or giving

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, 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.

WARNING
This information is intended for use by individuals
possessing adequate backgrounds of electrical and
mechanical experience. Any attempt to repair a central
air conditioning product may result in death, personal
injury or property damage. The manufacturer or seller
cannot be responsible for the interpretation of this
information, no can it assume any liability in
connection with its use.
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 that 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.
Failure to follow these recommendations could result in
equipment damage.
Important!
Environmental Concerns - Scientific research has
shown that certain man-made chemicals can affect the
earths 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
(HCFCs). Not all refrigerants containing these compounds
have the same potential impact to the environment. Trans
advocates the responsible handling of all refrigerants -
including industry replacements for CFCs such as HCFCs
and HFCs.
Responsible Refrigerant Practices - Trane believes
that responsible refrigerant practices are important to the
environment, our customers and the air-conditioning
industry. All technicians who handle refrigerants must be
certified. The Federal Clean Air Act (Section 608) sets forth
the requirements for handling, reclaiming, recovering and
recycling of certain refrigerants and the equipment that is
used in these service procedures. In addition, some states
or municipalities may have additional requirements that
must also be adhered to for responsible management of
refrigerants. Know the applicable laws and follow them.
