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 flmctions such
as cleaning coils. All other operations should be performed by
trained service personnel.
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
quenching cloth and fire extinguisher nearby when brazing. Use
care in handling, rigging, and setting bulky equipment.
Read these instructions 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 nfinor personal
injury or product and property damage. NOTE is used to highlight
suggestions which will result in enhanced installation, reliability, or
operation.
ELECTRICALSHOCK HAZARD
Failure to follow this warning could result in personal
injury or death.
Before installing, modifying, or servicing system, 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 iniury,
and/or property damage.
Never use air or gases containing
oxygen for leak testing or operating
refrigerant compressors. Pressurized
nfixtures of air or gases containing
oxygen can lead to an explosion.
EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in equipment
damage or improper operation.
Do not bury more than 36 in. (914 ram) of refrigerant pipe
in the ground. If any section of pipe is buried, there must be
a 6 in. (152 ram) vertical rise to the valve connections on
the outdoor units. If more than the recommended length is
buried, refrigerant may nfigrate to the cooler buried section
during extended periods of system shutdown. This causes
refrigerant slugging and could possibly damage the
compressor at start-up.
SYSTEM REQUIREMENTS
Allow sufficient space for airflow and servicing unit. See Fig. 1
for nfinimuna required distances between unit and walls or ceilings.
Recommended Connection Method for Power and Communi-
cation Wiring (To minimize communication wiring interfer-
enceL
Power Wiring:
The main power is supplied to the outdoor unit. The field supplied
connecting cable from the outdoor unit to 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.
Consult your local building codes and the NEC (National
Electrical Code) or CEC (Canadian Electrical Code) for special
requirements.
All wires must be sized per NEC or CEC and local codes. Use
Electrical Data table MCA (nfininmm circuit amps) and MOCP
(naaxinmm over current protection) to correctly size the wires and
the disconnect fuse or breakers respectively.
Per caution note, only copper conductors with a nfinimuna 300 volt
rating and 2/64-inch thick insulation must be used.
Communication Wiring:
A separate shielded copper conductor only, with a nfinimun_ 300
volt rating and 2/64-inch thick insulation, must be used as the
communication wire from the outdoor unit to the indoor unit.
To nfininfize voltage drop of the control wire, use the following
wire size and maxinmna lengths shown in the chart below:
Wire Size Length
ft (m)
18 AWG 50 (15)
16 AWG 50 (15) to 100 (30)
When installing in an application where there is high
electrical frequency all wires should be shielded.
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 nfinimuna 300 volt
rating and 2/64 inch thick insulation.
