* Caution during addition of refrigerant
Max. amount of additional refrigerant is 1.8 lbs (800
g).
Charge the refrigerant accurately. Overcharging
may cause serious trouble with the compressor.
* Minimum refrigerant pipe is 16’5”(5 m).
This may cause a malfunction of the compressor or
other devices.

Flare nuts and flaring
• The flare nuts and flaring are different from those for
the conventional refrigerant.
Use the flare nuts supplied with the air conditioner or
those for R410A.
• Before performing flaring, carefully read
“REFRIGERANT PIPING”
Insulation
Both lines need to be insulated. Use a minimum 0.4”
(10 mm) wall thickness.
• The main power is supplied to the outdoor unit. The
field supplied connecting cables from the outdoor
unit to the indoor unit consist for 4 wires and provides
the power for the indoor unit as well as the
communication signal between the outdoor and
indoor unit.
• Consult local building codes, NEC (National
Electrical Code) or CEC (Canadian Electrical Code)
for special requirements.
• The following are the electrical requirements.

4 PRECAUTIONS FOR SAFETY
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 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
•
Ask an authorized dealer or qualified installation professional to install/maintain the air conditioner.
Perform installation work properly according to the Installation Manual.
Inappropriate installation may result in water leakage, electric shock or fire.
• Be sure to ground the equipment
Improper grounding may cause an electric shock.
Do not connect ground wires to gas pipes, water pipes, lightning rods or ground wires for telephone wires.
• Turn off the circuit breaker before attempting any electrical work and maintenance.
Make sure the circuit breaker is off. Failure to do so may cause electric shock.
Use an exclusive power circuit for the air conditioner. Use the rated voltage.
• When moving the air conditioner for installation to another place, be very careful not to allow the specified
refrigerant (R410A) to become mixed with any other gaseous body into the refrigeration cycle.
If air or any other gas mixes with the refrigerant, the gas pressure in the refrigeration cycle will become abnormally
high and it may result in the pipe bursting or personal injuries.
• Do not modify this unit by removing any of the safety guards or by by-passing any of the safety interlock
switches.
• Do not touch the intake or aluminium fins of the outdoor unit.
Doing so may result in injury.
• Tighten the flare nut with a torque wrench in the specified manner.
Excessive tightening of the flare nut may cause a crack in the flare nut after a long period, which may result in
refrigerant leakage.
• Install the air conditioner securely in a location where the base can sustain the weight of the unit adequately.
• If refrigerant gas has leaked during the installation work, ventilate the room immediately.
If the leaked refrigerant gas comes in contact with fire, noxious gas may be generated.
• After the installation work, confirm that refrigerant gas does not leak.
If refrigerant gas leaks into the room and flows near a fire source, such as a cooking range, noxious gas may be
generated.
• Electrical work must be performed by a qualified electrician in accordance with the NEC and local code. Make
sure the air conditioner uses an exclusive power supply.
An insufficient power supply capacity or inappropriate installation may cause fire.
• Use only the specified wiring during the unit installation. Ensure that all terminals are securely fixed, so
preventing any external forces having a negative effect on the terminals.
