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.
