SYMBIO ™ 700 INFORMATION & TROUBLESHOOTING MANUAL

APRIL 2021 ~UNOFFICIAL~

Introduction

This publication covers both electromechanical

and Symbio™ controls. Due to the more

complex application and service opportunities,

greater emphasis is placed on units with

Symbio™ controls.

This publication does not cover all aspects of

service. It assumes the service person is an

experienced commercial service technician with

a strong background in electrical controls and

DC circuits. If you are not experienced and fully

qualified in HVAC service, do not attempt to use

this manual to service equipment.

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 HFCs 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.
