When Transporting
……………………………………………………………………
Be careful when picking up and moving the indoor and
outdoor units. 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
……………………………………………………………………
…In a Room
Properly insulate any tubing run inside a room to prevent
“sweating” that can cause dripping and water damage to
walls and floors.
…In Moist or Uneven Locations
Use a raised concrete pad or concrete blocks to provide a
solid, level foundation for the outdoor unit. This prevents
water damage and abnormal vibration.
…In an area with High Winds
Securely anchor the outdoor unit down with bolts and a
metal frame. Provide a suitable air baffle.
…In a Snowy Area
(for Heat Pump-type Systems)
Install the outdoor unit on a raised platform that is higher
than drifting snow. Provide snow vents.
When Connecting Refrigerant Tubing
……………………………………………………………………
•
Execute enough ventilation in case refrigerant gas leaks
during operations. Be careful not to contact the refrigerant
gas with the flame. It will cause the generation of
poisonous gas.
• Keep all tubing runs as short as possible.
• Use the flare method for connecting tubing.
• Apply refrigerant lubricant to the matching surfaces of
the flare and union tubes before connecting them, then
tighten the nut with a torque wrench for a leak-free
connection.
• Check carefully for leaks before starting the test run.
NOTE
Depending on the system type, liquid and gas lines may
be either narrow or wide. Therefore, to avoid confusion,
the refrigerant tubing for your particular model is specified
as either “narrow” or “wide” rather than as “liquid” or “gas”.
When Servicing
……………………………………………………………………
• Turn the power OFF at the main power box before
opening the unit to check or repair electrical parts and
wiring.
• Keep your fingers and clothing away from any moving
parts.
• Clean up the site when finished servicing. Don’t forget
to check that no metal scraps or bits of wiring have
been left inside the unit.

WHO SHOULD USE THIS MANUAL
This service manual is made to assist the service technician apply his knowledge and
training to this model air conditioner. This manual is written both for experienced service
persons and those who are new to air conditioning service. To help those with less
experience or who are new to this kind of unit we have included more explanations of
basic procedures in simple language than is usual in some service manuals. The experi-
enced technician will of course find he knows many of these things already and can go
directly to the procedures and information he needs; the less experienced technician will
better understand what to do even before he arrives on the job, and therefore be better
able to work by himself as well as assist the more experienced technician.

2-1 Room Temperature Control
The Unit adjusts room temperature by turning the outdoor unit’s compressor ON and OFF.
This process is controlled by the thermostat located in the remote control unit.
The figures on this and the next pages show how each part of the system performs when
the room temperature changes and the thermostat activates the compressor to start
(thermo ON) or stop (thermo OFF). Fig. 6 shows about the cooling cycle.

Chart Summary and Explanations
❑Once the compressor starts, it keeps running for 5 minutes.
❑Once the compressor stops, it will not start running again for 3 minutes.
❑If you change the operation mode during the cooling cycle, the control circuit stops the
compressor for 3 minutes.
❑For 5 minutes after the compressor is first turned on, and for 3 minutes after it is turned off,
the compressor is not controlled by the room sensor.
❑Thermo ON: When room temperature rises 0.5°C above the set temperature T˚,
(T˚+0.5 °C):
Compressor ➞ ON
❑Thermo OFF: When the room temperature is equal to or below the set temperature T˚:
Compressor ➞ OFF
❑In case of wireless remote control model (GS type).
• The remote control unit sends the temperature signal to the air conditioner regularly at 3
minute intervals. If the signal from the remote control unit stops for more than 10 minutes
due to the damage of the remote control unit or other trouble, the air conditioner will
switch to the temperature sensor which is built in the indoor unit and control the room
temperature. In these cases, the temperature around the remote contorl unit may differ
from the temperature detected at the air conditioner’s position.
• If the remote control is located near a heat source, such as a space heater or in direct
sunlight, press the A/C SENSOR button to switch to the sensor in the indoor unit.

2-2 Freeze Prevention
Freeze Prevention keeps the indoor heat exchange coil from freezing. Freezing reduces
the efficiency of the unit, and frost buildup on the coil blocks cool air circulation from the
indoor unit’s fan.

2-3 Outdoor Fan Control
• In low outdoor temperature, the outdoor fan is set automatically from HIGH to LOW to
prevent the indoor heat exchanger from freezing.
• When the outdoor temperature falls below 25.5°C, the outdoor fan is set from HIGH to
LOW automatically. When the outdoor temperature rises to 27.5°C, the outdoor fan is
set from LOW to HIGH automatically.

4-4 Checking the Electrical Components
(1) Measurement of Insulation
Resistance
• The electrical insulation is acceptable when the
resistance exceeds 1 MΩ.
1Power Supply Wires
Clamp the earthed wire of the Power Supply wires
with a lead clip of the insulation resistance tester and
measure the resistance by placing a probe on either
of the power wires. (Fig. 42)
Then measure the resistance between the earthed
wire and the other power wires. (Fig. 42)
2Indoor Unit
Clamp an aluminum plate fin or copper tube with the
lead clip of the insulation resistance tester and
measure the resistance by placing a probe on the
terminal plate (Fig. 43)
3Outdoor Unit
Measure the resistance by placing a probe on the
terminal plate in the same manner as explained
above 2. (Fig. 43)
4Measurement of Insulation Resistance for
Electrical parts
• Disconnect the connector of the desired electric
part from terminal plate, P.C.B. Ass’y, etc. (Fig. 44)
• Similarly, disconnect the lead wires from
compressor, capacitor, etc. (Fig. 45)
• Measure the resistance in the same manner as
illustrated on the right.
Refer to Electrical Wiring Diagram.
NOTE
If the probe does not enter the hole because the
hole is too narrow, use a probe with a thinner pin.

• Primary 220-240 V ; Measure the resistance between two WHT lead wire
terminals of socket connected to power transformer.
• Secondary 10.6V ; Measure the resistance between two BRN lead wires.
Refer to “1–3–(A) Other component specifications”.
2Indoor fan motor (FMI) ............... Indoor unit *Measure the coil resistance.
• Measure the resistance between each terminal of the socket connected to
the indoor fan motor.
Refer to “1–2–(A) Major component specifications”.
3 Outdoor fan motor (FMO) ........... Outdoor unit *Measure the coil resistance.
• Measure the resistance in the same manner as explained above 2.
Refer to “1–2–(B) Major component specifications”.
4Fan motor capacitor ............ Both in indoor and outdoor unit
• Remove the lead wires from the capacitor terminals,
and then place a probe on the capacitor terminals as
shown in Fig. 47. Observe the deflection of the pointer,
setting the resistance measuring range of the multimeter
to the maximum value.
• The capacitor is “acceptable” if the pointer bounces to a
great extent and then gradually returns to its original
position.
NOTE
The range of deflection and the deflection time differ according to
the capacity of the capacitor.
