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
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 current editions of the National Electrical Code (NEC) NFPA

70. In Canada, refer to current editions of the Canadian electrical code
CSA 22.1.

!

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.

ELECTRICAL SHOCK 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.

!

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
compressor at start−up.

WARNING

CAUTION

GENERAL

These instructions cover the installation, start−up and servicing of
outdoor and indoor units ductless systems.

SYSTEM REQUIREMENTS

Allow sufficient space for airflow and servicing unit. See Fig. 4 for
minimum required distances between unit and walls or ceilings.

Piping
IMPORTANT: Both refrigerant lines must be insulated separately.

S Minimum refrigerant line length between the indoor and outdoor

units is 10 ft. (3 m).

S The following maximum lengths are allowed.

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 the
fuse or breakers respectively.

Per the 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 the communication
wiring and the other is a ground wire.

Recommended Connection 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.

T o minimize a 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.

!

EQUIPMENT DAMAGE HAZARD

Failure to follow this caution may result in equipment
damage or improper operation.

S Wires should be sized based on NEC and local codes.
S Use copper conductors only with a 600 volt rating and

double insulated copper wire.

!

EQUIPMENT DAMAGE HAZARD

Failure to follow this caution may result in equipment
damage or improper operation.

S Comply with local codes while running wire from indoor

unit to outdoor unit.

S Every wire must be connected firmly. Loose wiring may

cause a terminal to overheat or result in unit
malfunction. A fire hazard may also exist. Ensure all
wiring is tightly connected.

S No wire should touch refrigerant tubing, the compressor

or any moving parts.

S Disconnecting means must be provided and must be

located within sight and readily accessible from the air
conditioner.

S Connecting the cable with conduit shall be routed

through a hole in the conduit panel.
