Warnings, Precautions, Notices
Safety advisories appear throughout this manual are required. Your personal safety and the proper
operation of this machine depend upon the strict observance of these precautions.
The three types of advisories are defined as follows:
Important
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 and HCFCs such as saturated or unsaturated CFCs and HCFCs.
Important 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 according to local rules. For the USA, 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.
WARNING Indicates a potentially hazardous situation which, if not avoided, could
result in death or serious injury.
PRECAUTIONsIndicates a potentially hazardous situation which, if not avoided, could
result in minor or moderate injury. It could also be used to alert against
unsafe practices.
NOTICE: Indicates a situation that could result in equipment or property-damage
only accidents.

Drilling a hole in existing ceiling (horizontal)
1. Drill a 880 x 880mm hole following the outline indicated on the mounting template.
•The center of the hole must be placed in the same position corresponding to the body of the
air-conditioning unit.
•Determine the lengths and outlets of connecting piping, drain piping, and wiring cables.
•In order to balance the installation in the ceiling and also to avoid vibrations, install wedges
as may be deemed necessary.
2. Determine the position of the support rods following perforations for rods indicated on the
mounting template.
•Drill four holes of 12mm dia. and 45-50mm in depth at the places indicated on the ceiling.
Insert expansible anchors.
•Place the hollow side of the rods towards the expansible anchor. Determine the length of
installation rods based on the height of the ceiling. Cut away any remaining and
unnecessary extension. If ceiling height is taller, determine the length of installation rods
according to the space available for installation.
3. Apply equal torque to hex nuts on all four hanging rods to ensure the correct balance of the unit.
•Place the drain pipe in the right direction to allow it to adjust to the movement of the water
level controller.
•Center the unit in a manner that may ensure uniform spacing between the body of the unit
and the four sides of the ceiling. The lower side of the body of the unit must penetrate the
ceiling in approximately 10 to12 mm.
•In general, the L distance represents half of the length of the installation rod.
•Once the unit has been installed, apply final torque to all nuts.
Drilling a hole in a ceiling of new construction
1. In the case of new construction, hanging rods may be inserted in advance (see point No. 2 in
section above). Rods must have the capacity to support the weight of the indoor unit and must
be unable to become loose due to the effects derived from concrete compression.
2. After installing the body of the unit, install the mounting template over the air conditioning unit
using M6 x 12 screws in order to determine in advance the sizes and positions of ceiling holes.
•Before the installation, make sure the ceiling maintains proper leveling.
•Refer to point No. 1.
