SAFETY CONSIDERATIONS
Installing,starting up, and servicing air−conditioning equipment can be
hazardous due to system pressures, electrical components, and
equipment location (roofs, elevated structures, etc.).
Only trained, qualified installers and service mechanics should install,
start−up, and service this equipment.
Untrained personnel can perform basic maintenance functions such as
cleaning coils. All other operations should be performed by trained
servicepersonnel.
When working on the equipment, observe precautions in the literature and
on tags, stickers, and labels attached to the equipment.
Follow all safety codes. Wear safety glasses and work gloves. Keep a
quenching cloth and fire extinguisher nearby when brazing. Use care in
handling, rigging, and setting bulky equipment.
Read this manual thoroughly and follow all warnings or cautions included
in literature and attached to the unit. Consult local building codes and
National Electrical Code (NEC) for special requirements.
Recognize safety information. This is the safety−alert symbol !
! . When
you see this symbol on the unit and in instructions or manuals, be alert to
the potential for personal injury. Understand these signal words:
DANGER, WARNING, and CAUTION. 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 signifies hazards which could result in personal injury or
death. CAUTION is used to identify unsafe practices which may result in
minor personal injury or product and property damage. NOTE is used to
highlight suggestions which will result in enhanced installation, reliability,
or operation.
!WARNING
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal
injury or death.
Before installing, modifying, or servicing the system,
the main electrical disconnect switch must be in the OFF
position. There may be more than 1 disconnect switch.
Lock out and tag switch with a suitable warning label.
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 operating
refrigerant compressors. Pressurized
mixtures of air or gases containing
oxygen can lead to an explosion.
!WARNING
CAUTION
!
EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in equipment
damage or improper operation.
Do not bury more than 36 in. (914 mm) of refrigerant pipe
in the ground. If any section of pipe is buried, there must be
a 6 in. (152 mm) vertical rise to the valve connections on
the outdoor units. If more than the recommended length is
buried, refrigerant may migrate to the cooler buried section
during extended periods of system shutdown. This causes
refrigerant slugging and could possibly damage the
compressorat start−up.

WIRING
All wires must be sized per NEC (National Electrical Code) or CEC
(Canadian Electrical Code) and local codes. Use the Electrical Data
table MCA (minimum circuit amps) and MOCP (maximum over
current protection) to correctly size the wires and the disconnect fuse or
breakers respectively.
Per caution note, only Stranded copper conductors with a 600 volt
rating and double insulated copper wire must be used.
NOTE: The use of BX cable is not recommended.
Recommended Connection Method for Power and Communication
Wiring − Power and Communication Wiring:
The main power is supplied to the outdoor unit. The field supplied 14/3
power/communication wiring from the outdoor unit to the indoor unit
consists of four (4) wires and provides the power for the indoor unit.
Two wires are high voltage AC power, one is communication wiring
and the other is a ground wire.
RecommendedConnection Method for Power and Communication
Wiring (To minimize communication wiring interference)
PowerWiring:
The main power is supplied to the outdoor unit. The field supplied
power wiring from the outdoor unit to the indoor unit consists of three
(3) wires and provides the power for the indoor unit. Two wires are
high voltage AC power and one is a ground wire.
To minimize voltage drop, the factory recommended wire size is 14/2
stranded with a ground.
Communication Wiring:
A separate shielded stranded copper conductor only, with a minimum
600 volt rating and double insulated copper wire, must be used as the
communication wire from the outdoor unit to the indoor unit. Please
use a separate shielded 16GA stranded control wire.
CAUTION
!
EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in equipment
damage or improper operation.
Wires should be sized based on NEC and local codes.
Use copper conductors only with a 600 volt rating and
double insulated copper wire.
CAUTION
!
EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in equipment
damage or improper operation.
SBe sure to comply with local codes while running wire
from indoor unit to outdoor unit.
SEvery wire must be connected firmly. Loose wiring may
cause terminal to overheat or result in unit malfunction.
A fire hazard may also exist. Therefore, be sure all
wiring is tightly connected.
SNo wire should be allowed to touch refrigerant tubing,
compressoror any moving parts.
SDisconnecting means must be provided and shall be
located within sight and readily accessible from the air
conditioner.
SConnecting cable with conduit shall be routed through
hole in the conduit panel.
