SAFETY CONSIDERATIONS
Installation and servicing of air-conditioning equipment can be
hazardous due to system pressure and electrical components.
Only trained and qualified service personnel should install, re-
pair, or service air-conditioning equipment.
Untrained personnel can perform basic maintenance functions
of cleaning coils and filters and replacing filters. All other op-
erations should be performed by trained service personnel.
When working on air-conditioning equipment, observe precau-
tions in the literature, tags and labels attached to the unit, and
other safety precautions that may apply.
Follow all safety codes, including ANSI (American National
Standards Institute) Z223.1. Wear safety glasses and work
gloves. Use quenching cloth for unbrazing operations. Have
fire extinguisher available for all brazing operations.
It is important to recognize safety information. This is the safe-
ty-alert symbol
. When you see this symbol on the unit and
in instructions or manuals, be alert to the potential for personal
injury.
Understand the signal words DANGER, WARNING, CAU-
TION, and NOTE. These words are used with the safety-alert
symbol. DANGER identifies the most serious hazards which
will
result in severe personal injury or death. WARNING signi-
fies hazards which
could
result in personal injury or death.
CAUTION is used to identify unsafe practices, which
may
re-
sult in minor personal injury or product and property damage.
NOTE is used to highlight suggestions which
will
result in en-
hanced installation, reliability, or operation.
UNIT ARRANGEMENT AND ACCESS
General
Figure 1 and 2 show general unit arrangement and access
locations.
WARNING
ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal inju-
ry or death.
Before performing service or maintenance operations on
unit, LOCKOUT/TAGOUT the main power switch to unit.
Electrical shock and rotating equipment could cause severe
injury.
WARNING
ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal inju-
ry or death.
Units with convenience outlet circuits may use multiple
disconnects. Check convenience outlet for power status
before opening unit for service. Locate its disconnect
switch, if appropriate, and open it. Lock-out and tag-out
this switch, if necessary.
WARNING
UNIT OPERATION AND SAFETY HAZARD
Failure to follow this warning could cause personal injury,
death and/or equipment damage.
Puron
®
(R-410A) refrigerant systems operate at higher pres-
sures than standard R-22 systems. Do not use R-22 service
equipment or components on Puron refrigerant equipment.
WARNING
FIRE, EXPLOSION HAZARD
Failure to follow this warning could result in death, serious
personal injury and/or property damage.
Never use air or gases containing oxygen for leak testing or
for operating refrigerant compressors. Pressurized mixtures
of air or gases containing oxygen can lead to an explosion.
WARNING
FIRE, EXPLOSION HAZARD
Failure to follow this warning could result in death, serious
personal injury and/or property damage.
Never use non-certified refrigerants in this product. Non-
certified refrigerants could contain contaminates that could
lead to unsafe operating conditions. Use ONLY refrigerants
that conform to AHRI Standard 700.
CAUTION
UNIT DAMAGE HAZARD
Failure to follow this caution may result in reduced unit
performance or unit shutdown.
High velocity water from a pressure washer, garden hose,
or compressed air should never be used to clean a coil. The
force of the water or air jet will bend the fin edges and in-
crease airside pressure drop.
IMPORTANT: Failure to follow this ALERT can result
in an unnecessary evacuation of the facility.
Pressing the controller’s test/reset switch for longer than
seven seconds will put the duct detector into the alarm
state and activate all automatic alarm responses.
IMPORTANT: Lockout/tag-out is a term used when elec-
trical power switches are physically locked preventing
power to the unit. A placard is placed on the power switch
alerting service personnel that the power is disconnected.
