Warnings, Cautions and Notices
Warnings, Cautions and Notices.
Note that warnings,
cautions and notices 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. Cautions are designed to alert
personnel to hazardous situations that could result in
personal injury, while notices indicate a situation that could
result in equipment or property-damage-only accidents.
Your personal safety and the proper operation of this
machine depend upon the strict observance of these
precautions.
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.
Overview of Manual
One copy of the appropriate service literature ships inside
the control panel of each unit. The procedures discussed in
this manual should only be performed by qualified,
experienced HVAC technicians.
Note:
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.
This booklet describes the proper installation, startup,
operation, and maintenance procedures for TC_, TE_, and
YC_22.9 to 50 Ton CV (Constant Volume), VAV (Variable Air
Volume), and SZ VAV (Single Zone Variable Air Volume)
applications. Refer to the table of contents for a listing of
specific topics. Refer to
“Diagnostics,” p. 104
for
troubleshooting information.
ATTENTION:
Warnings, Cautions and Notices 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
s
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
WARNING
Personal Protective Equipment (PPE)
Required!
Installing/servicing this unit could result in exposure to
electrical, mechanical and chemical hazards.
•
Before installing/servicing this unit, technicians
MUST put on all Personal Protective Equipment (PPE)
recommended for the work being undertaken.
ALWAYS refer to appropriate MSDS sheets and OSHA
guidelines for proper PPE.
•
When working with or around hazardous chemicals,
ALWAYS refer to the appropriate MSDS sheets and
OSHA guidelines for information on allowable
personal exposure levels, proper respiratory
protection and handling recommendations.
•
If there is a risk of arc or flash, technicians MUST put
on all Personal Protective Equipment (PPE) in
accordance with NFPA 70E or other country-specific
requirements for arc flash protection, PRIOR to
servicing the unit.
Failure to follow recommendations could result in death
or serious injury.
WARNING
Proper Field Wiring and Grounding
Required!
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 electrical codes. Failure to
follow code could result in death or serious injury.
