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.

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 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,

nor can it assume any liability in connection with its use.

WARNING

Ground Required!

Follow proper local electrical code on requirements for grounding. Failure to follow

code 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.

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.

Preface

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.

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 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.

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.

MS-SVU29A-EN 5

This Owner’s Manual is given as a guide to good practices in the operation of a wall mounted

split system. However it does not contain all the service procedures for this unit, as these

procedures must be performed by a qualified service technician, through the maintenance

contract with a reputable service company.

Read these operation Instructions completely before using the air conditioning.

Warranty

Warranty is based on the general terms and conditions by country. The warranty is void if the

equipment is modified or repaired without the written approval of The Trane Company, if the

operating limits are exceeded or if the control system or the electrical wiring is modified.

Damage due to inappropriate installation, lack of knowledge or failure to comply with the

manufacturer’s instructions, is not covered by the warranty obligation.

If the installation does not conform to the rules described in Installation Manual, it may entail

cancellation of warranty and liabilities by The Trane Company.

Reception

On arrival, inspect the unit before signing the delivery note. Specify any damage of the unit on

the delivery note, and send a registered letter of protest to the last carrier of the goods within 72

hours of delivery. Notify the dealer at the same time.

The unit should be totally inspected within 7 days of delivery. If any concealed damage is

discovered, send a registered letter of protest to the carrier within 7 days of delivery and notify

the local dealer.

About the Unit

These units are assembled, pressure tested, dehydrated, charged and run tested before shipment.

Refrigerant

The refrigerant provided by the manufacturer complies with all the requirements for our units.

When using a recycled or reprocessed refrigerant, we recommend its qualities be as good as

those of a new refrigerant. It is necessary to have the refrigerant tested by a qualified laboratory.

Failure to do so could void the warranty.

Important

These instructions do not cover all variations in systems, nor do they provide for every possible

contingency to be met in connection with installation. Should further information be desired or

should particular problems arise which are not covered sufficiently in this manual, the matter

should be referred to your authorized Trane dealer.

The followings are general recommendations that are necessary to follow to obtain maximum

performance from your air conditioner:

• Don’t leave windows and doors open for a long time while operating the air conditioner. It

can decrease the air conditioning capacity.

• Don’t put a space heater near the air conditioner, it can decrease the air conditioner capacity.

• When the air conditioner will not be used for a long time, turn off the power supply.

NOTICE

Air Flow Restriction!

Ensure no restriction of air flow to or from the unit or system. Failure to do so could

result in poor performance or cause equipment damage.

WARNING

Safety Recommendations!

The followings are safety recommendations that if not followed could result in death or

serious injury:

• If a burning smell or smoke occurs, please turn off the power supply and contact

your Trane dealer. The unit may be damaged, and may cause electric shock or fire.

• Do not use flammable sprays near the air conditioner. They can cause a fire or

explosion.

• Don't attempt to repair the air conditioner by yourself. Incorrect repair could lead

to an electric shock or fire, so repairs should only be made by qualified Trane

technicians.

• The power supply must be of proper amperage and conform with local codes.

• Please don't cut or damage the power cords and control cords. Electric shock or

fire could result. If they are damaged, please ask the qualified personnel to change

them.

• Do not operate the unit without the filters installed. Otherwise, dirt may enter the

unit and cause damage. Filters should be removed and cleaned periodically to

assure maximum efficiency.
