Trane IntelliPak 1 with Symbio 800 Installation and operating instructions

SAFETY WARNING
Only qualified personnel should install and service the equipment. The installation, starting up, and servicing of heating, ventilating, and air-conditioning equipment
can be hazardous and requires specific knowledge and training. Improperly installed, adjusted or altered equipment by an unqualified person could result in death or
serious injury. When working on the equipment, observe all precautions in the literature and on the tags, stickers, and labels that are attached to the equipment.

Introduction
Read this manual thoroughly before operating or servicing
this unit.
Warnings, Cautions, and Notices
Safety advisories appear throughout this manual as
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:
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 could also be used to alert against unsafe
practices.
NOTICE
Indicates a situation that could result in equipment
or property-damage only accidents.
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.
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
Proper Field Wiring and Grounding
Required!
Failure to follow code could result in death or serious
injury.
All field wiring MUST be performed by qualified
personnel. Improperly installed and grounded field
wiring poses FIRE and ELECTROCUTION hazards. To
avoid these hazards, you MUST follow requirements
for field wiring installation and grounding as
described in NEC and your local/state/national
electrical codes.
WARNING
Personal Protective Equipment (PPE)
Required!
Failure to wear proper PPE for the job being
undertaken could result in death or serious injury.
Technicians, in order to protect themselves from
potential electrical, mechanical, and chemical
hazards, MUST follow precautions in this manual and
on the tags, stickers, and labels, as well as the
instructions below:
• Before installing/servicing this unit, technicians
MUST put on all PPE required for the work being
undertaken (Examples; cut resistant gloves/
sleeves, butyl gloves, safety glasses, hard hat/
bump cap, fall protection, electrical PPE and arc
flash clothing). ALWAYS refer to appropriate
Safety Data Sheets (SDS) and OSHA guidelines
for proper PPE.
• When working with or around hazardous
chemicals, ALWAYS refer to the appropriate
SDS and OSHA/GHS (Global Harmonized
System of Classification and Labelling of
Chemicals) guidelines for information on
allowable personal exposure levels, proper
respiratory protection and handling
instructions.
• If there is a risk of energized electrical contact,
arc, or flash, technicians MUST put on all PPE in
accordance with OSHA, NFPA 70E, or other
country-specific requirements for arc flash
protection, PRIOR to servicing the unit. NEVER
PERFORM ANY SWITCHING, DISCONNECTING,
OR VOLTAGE TESTING WITHOUT PROPER
ELECTRICAL PPE AND ARC FLASH CLOTHING.
ENSURE ELECTRICAL METERS AND
EQUIPMENT ARE PROPERLY RATED FOR
INTENDED VOLTAGE.

RT-SVX072D-EN 3
WARNING
Follow EHS Policies!
Failure to follow instructions below could result in
death or serious injury.
• All Trane personnel must follow the company’s
Environmental, Health and Safety (EHS) policies
when performing work such as hot work,
electrical, fall protection, lockout/tagout,
refrigerant handling, etc. Where local
regulations are more stringent than these
policies, those regulations supersede these
policies.
• Non-Trane personnel should always follow local
regulations.
Overview of Manual
Note: This document is customer property and must be
retained by the unit owner for use by maintenance
personnel.
This unit is equipped with Symbio 800 controls. Refer to the
“Start-Up” and “Manual Override” procedures within this
Installation, Operation, and Maintenance manual and the
latest edition of the appropriate programming manual for
Variable Air Volume (VAV), or Single Zone Variable Air
Volume (SZVAV) applications before attempting to operate
or service this equipment.
Important: The procedures discussed in this manual
should only be performed by qualified and
experienced HVAC technicians.
This booklet describes proper installation, start-up,
operation, and maintenance procedures for 20 through 130
ton rooftop air conditioners designed for Single Zone VAV
(SZVAV) and Variable Air Volume (VAV) applications. By
carefully reviewing the information within this manual and
following the instructions, the risk of improper operation
and/or component damage will be minimized.
Note: One copy of the appropriate service literature ships
inside the control panel of each unit.
It is important that periodic maintenance be performed to
help assure trouble-free operation. Should equipment
failure occur, contact a qualified service organization with
qualified, experienced HVAC technicians to properly
diagnose and repair this equipment.
Important: DO NOT release refrigerant to the atmosphere!
If adding or removing refrigerant is required, the service
technician must comply with all federal, state, and local
laws.
