IMPORTANT!
Please Read Before Starting
This air conditioner meets strict safety and operating
standards. As the installer or service person, it is an
important part of your job to install or service the system so it
operates safely and efficiently.
For safe installation and trouble-free operation, you
must:
• Carefully read the INSTRUCTION MANUAL and
INSTALLATION INSTRUCTIONS attached to each air
conditioner before beginning.
• Follow each installation or repair step exactly as shown.
• Observe all local, state, and national electrical codes.
• Pay close attention to all warning and caution notices given
in this manual.
This symbol refers to a hazard or unsafe practice which can
result in severe personal injury or death.
This symbol refers to a hazard or unsafe practice which can
result in personal injury or product or property damage.
If Necessary, Get Help
These instructions are all you need for most installation sites
and maintenance conditions. If you require help for a special
problem, contact our sales/service outlet or your certified
dealer for additional instructions.
SPECIAL PRECAUTIONS
When Wiring
ELECTRICAL SHOCK CAN CAUSE SEVERE PERSONAL
INJURY OR DEATH. ONLY A QUALIFIED, EXPERIENCED
ELECTRICIAN SHOULD ATTEMPT TO WIRE THIS
SYSTEM.
• All wiring must conform to local electrical codes.
• Each unit must be properly grounded with a ground (or
earth) wire or through the supply wiring.
• DO NOT, under any circumstances, cut or remove the third
(ground) prong from the power cord plug.
• DO NOT use an adapter Plug or extension cord.
• DO NOT use a damaged power cord, plug, or wall outlet.
Replace them immediately.
• DO NOT change the internal wiring or any part of the
system.
• DO NOT turn the air conditioner on and off by plugging and
unplugging. Use the Operation switch.
When Transporting
Be careful when picking up and moving the air conditioner.
Get a partner to help, and bend your knees when lifting to
reduce strain on your back. Sharp edges or thin aluminum
fins on the air conditioner can cut your fingers.
When Installing
Place of Installation
• If possible, install the unit in a shady location.
• Install it at a spot where optimum air circulation can be
obtained. No chairs or other obstructions are allowed in
front of the air conditioner.
• Keep enough space from any outside obstruction (wall,
bush, etc.).
• As a safety measure, it is recommended that two people
install the unit.
• Hold the unit securely, and be careful not to drop any parts
if the air conditioner is being installed on an upper floor of a
multistory building.
When Servicing
• Turn the power OFF at the main power box (mains) before
opening the unit to check or repair electrical parts and
wiring.
• Keep fingers and clothing away from any moving parts.
• Clean up the site after you finish, remembering to check
that no metal scraps or bits of tools have been left inside
the unit being serviced.
Others
• Ventilate any enclosed areas when installing or testing the
refrigeration system. Escaped refrigerant gas, on contact
with fire or heat, can produce dangerously toxic gas.
• Confirm upon completing installation that no refrigerant gas
is leaking. If escaped gas comes in contact with a stove,
gas water heater, electric room heater or other heat source,
it can produce dangerously toxic gas.

Black dot in the chart indicates the following rating condition.
Indoor: 70°F (21.1°C) D.B.
Outdoor: 47°F (8.3°C) D.B. / 43°F (6.1°C) W.B.
2) Above characteristics indicates heat pump heating operation, which does not include
elctric heater operation.
3) Because this air conditioner heats a room by drawing in the heat of the outside
air (heat pump system), the heating efficiency will fall off when the outdoor temperature
is very low, which consequently makes the room temperature decrease. At this time,
heat is provided by the electric heater instead of heat pump. See page 44 for detail.

can damage it. Wait at least 3 minutes or so before starting it again.
●The compressor does not start up immediately even when the MODE selector
switch is set to COOL or HEAT (It starts operating in about 3 minutes).
●This is because rough 3-minute timer is built into the heat pump model in order
to protect the compressor. When operation is started up or restarted, the fan
operation begins immediately but the compressor starts operating after about
3-minute lag.

7-5-1. Room temp. thermistor (RTH) is defective.
A. Open
When thermistor opens, the air conditioner will be in the following conditions
as the controller tries to detect extremely low room temperature.
a) In Cooling mode: The air conditioner soon stops and will not start again. (Thermo.OFF)
Compressor does not run.
b) In Heating mode: The air conditioner continues to operate. (Thermo.ON)
(Heat pump) Electric heater does not stop.
As a result, the room becomes too warm.
B. Short
When thermistor is short, the air conditioner will be in the following conditions
as the controller tries to detect extremely high room temperature.
a) In Cooling mode: The air conditioner continues to operate. (Thermo.ON)
Compressor does not stop.
As a result, the room becomes too cold.
b) In Heating mode: The air conditioner soon stops and will not start again. (Thermo.OFF)
(Heat pump) Neither compressor nor electric heater runs.
Definition of Open or Short Circuit of Sensor (Thermistor)
Open...A lead wire is broken or disconnected or the circuit inside the temperature sensor is open .
Short... The protective cover of a lead wire has been damaged, and the exposed wire is touching another metal
part, or both lead wires have become exposed and are touching each other. Alternatively, the circuit inside
the temperature sensor is closed.

8-1. Measurement of Insulation
Resistance
●The insulation is in good condition if the resistance
exceeds 2MΩ.
8-1-1. Power Cord and Unit
Clamp the grounding prong of the power plug with a lead
clip of the insulation resistance tester and measure the
resistance by placing a probe on either of the two power
blade. (Fig. 1)
Then, also measure the resistance between the
grounding prong and other power blade. (Fig. 1)
8-1-2. Measurement of Insulation
Resistance for Electrical Parts
Disconnect the lead wires of the desired electric part
from terminal plate, switch, capacitor, etc. Similarly
disconnect the connector. Then measure the insulation
resistance.
(Figs. 2 to 3)
Refer to Electric Wiring Diagram.
If the probe cannot enter the poles because the hole is
too narrow then use a probe with a thinner pin.

The shape of the power plug may differ from that
of the air conditioner which you are servicing.
NOTE

8-2. Checking Motor Capacitor
Remove the lead wires from the capacitor terminals, and
then place probes on the capacitor terminals as shown in
Fig. 4. Observe the deflection of the pointer, setting the
resistance measuring range of the multimeter to the
maximum value.
The capacitor is “good” if the pointer bounces to a great
extent and then gradually returns to its original position.
The range of deflection and deflection time differ
according to the capacity of the capacitor.
8-3. Checking Fan Motor Winding
Referring to the electrical diagram, disconnect fan motor
connectors, and measure the resistance between each
lead wire with a multimeter.
The multimeter should be set in the X1 range. If the fan
motor is hot, allow a few minutes until it gets cooled
down.
When the resistances between each lead wire are those
listed in "2-2. Major Component Specifications" the fan
motor should be normal.
Checking compressor motor winding can be done in the
similar manner.
Remove the terminal cover of the compressor motor,
setting the resistance measuring range of the multimeter
to "X1Ω" and check the continuity between each pair out
of the 3 terminals as shown in Fig. 5.
Refer to "2-2. Major Component Specifications" for coil
resistance.
8-6. Checking Thermistor
(Only for heat pump model)
Unplug the 2P connector connected to PCB Ass´y and
measure the resistance of the thermistor with a
multimeter, which is set in the X1 kΩrange.
If the thermistor is normal, the multimeter should read
approximately 15kΩat 32˚F.

■ Defrosting Flowchart
■ Defrosting Mode Timing Chart
Once the air conditioner enters defrosting mode, it will not release defrosting until the
outdoor heat exchanger coil temperature rises above 39°F. During this period, heat is
provided by electric heater instead of by the heat pump.

CONTCYCLE
The location of Fan Switch differ according to models.
When set to CYCLE, fan operation synchronizes with that of compressor's (or heater's) thermo ON and
thermo OFF, thereby saving power. When set to CONT, fan continues to operate regardless of thermo
ON or thermo OFF condition.
