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.

All wires must be sized per NEC (National Electrical Code) or
CEC (Canadian Electrical Code) and local codes. Use 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 copper conductors with a minimum 300 volt
rating and 2/64- - inch thick insulation must be used. The use of
BX cable is not recommended.

Recommended Connection Method for Power
Communication Wiring - Power and Communication W

The main power is supplied to the outdoor unit. The field supplied
14/3 power/communication wiring from the outdoor unit to 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.

Recommended Connection Method for Power
Communication Wiring (To minimize communication
interfer

ence)

Power Wiring:

The main power is supplied to the outdoor unit. The field supplied
power wiring 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.
To minimize voltage drop, the factory recommended wire size is
14/2 stranded with a ground.

Communication Wiring:

A separate shielded copper conductor only, with a minimum 300
volt rating and 2/64- inch thick insulation, 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 minimum 300 volt

rating and 2/64 inch thick insulation.

!

EQUIPMENT DAMAGE HAZARD

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

S Be sure to comply with local codes while running wire

from indoor unit to outdoor unit.

S Every 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.

S No wire should be allowed to touch refrigerant tubing,

compressor or any moving parts.

S Disconnecting means must be provided and shall be

located within sight and readily accessible from the air
conditioner.

S Connecting cable with conduit shall be routed through

hole in the conduit panel.
