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.
In Case of Improper Installation
The manufacturer shall in no way be responsible for improper installation or maintenance service, including failure to
follow the instructions in this document.
When Installing…
…In a Ceiling or Wall
Make sure the ceiling/wall is strong enough to hold the
unit’s weight. It may be necessary to construct a strong
wood or metal frame to provide added support.
…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
• 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.
SPECIAL PRECAUTIONS
When Wiring
ELECTRICAL SHOCK CAN CAUSE SEVERE
PERSONAL INJURY OR DEATH. ONLY A
QUALIFIED, EXPERIENCED ELECTRICIAN
SHOULD ATTEMPT TO WIRE THIS SYSTEM.
• Do not supply power to the unit until all wiring and tubing
are completed or reconnected and checked.
• Highly dangerous electrical voltages are used in this
system. Carefully refer to the wiring diagram and these
instructions when wiring. Improper connections and
inadequate grounding can cause accidental injury or
death.
• Ground the unit following local electrical codes.
• Connect all wiring tightly. Loose wiring may cause overheating at connection points and a possible fire hazard.
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 Servicing
• Turn the power OFF at the main power box (mains)
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 after you finish, remembering to check
that no metal scraps or bits of wiring 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.

7-1-3. Baffle Plate for the Outdoor Unit
(CL
It is recommended to use baffle plates for models
CL1251, CL1852 and CL0951. The baffle plates are not
normally required for the other models.
When the outdoor unit is installed in a position exposed
to strong wind (like seasonal winds with low air temperature in winter), baffle plates must be installed on the
outdoor unit. (Fig. 5c)
This unit is designed so that the fan of the outdoor unit
runs at low speed when the air conditioner is operated
at low outdoor air temperatures. When the outdoor unit
is exposed to strong wind, the system pressure drops
because of the freeze protector.

NOTE
NOTE
If you are installing more than 1 indoor unit (up to 2) in
the same room, it is necessary for you to assign each
unit its own address so each can be operated by its own
remote control unit. You assign the addresses by
matching the switch positions of each indoor unit with
the switch positions of its remote control unit. The
switches of the remote control unit are shown in Fig. 8.
For instance, to set up 2 indoor units, switch Unit A’s
address switches. Then switch Unit B’s address switches.
It is important that you match the switches of the air
conditioner unit with the switches of its remote control
unit.

An indoor unit cannot be remote controlled if its remote
control unit is too far away (more than 26 ft.). If the
remote control unit does not seem to work correctly,
bring it closer to the unit being operated and try again.
For this reason, if the remote control unit is to be used
from a fixed position, operation should be checked at
that position before mounting.
● Room temperature control is obtained by cycling the compressor ON and OFF under control of the room
temperature sensor in the remote control unit.
● The room temperature (and other information) is transmitted every 3 minutes by the remote control unit to
the controller in the indoor unit.
● The control circuit will not attempt to turn the compressor ON until the compressor has been OFF for at
least 3 minutes. To protect the compressor from stalling out when trying to start against the high side
refrigerant pressure, the control circuit has a built-in automatic time delay to allow the internal pressure to
equalize.
● As a protective measure, the control circuit switches the compressor OFF after 5 minutes or more of com-
pressor operation.
● Thermo ON : When the room temperature is above T + 2°F (T°F is set temperature).
Compressor → ON
● Thermo OFF : When the room temperature is equal to or below set temperature T°F.
Compressor → OFF

● Dry operation uses the ability of the cooling cycle to remove moisture from the air, but by running at low
level to dehumidify without greatly reducing the room temperature. The air conditioner repeats the cycle of
turning ON and OFF automatically as shown in the chart below according to the room temperature.
● Intermittent ventilation occurs by switching the indoor fan speed between L ↔ LL.
● Dry operation does not occur when the room temperature is under 59°F, which is the Monitor Zone.
● When the compressor stops, the indoor fan stops as well.
8-3. Freeze Prevention
● This function prevents freezing of the indoor heat exchange coil.
● When the compressor has been running for 10 minutes or more and the temperature of the indoor heat
exchange coil falls below 34°F, the control circuit stops the compressor for at least 6 minutes. The compressor does not start again until the temperature rises above 46°F or 6 minutes have elapsed.

Low ambient fan speed control
● This function protects the compressor from being damaged due to flowback of the liquid refrigerant to the
compressor when the outdoor temperature is very low.
● When the air temp. thermistor (TH) on the outdoor units detects a change in temperature, the controller on
the electrical component box activates to control the fanspeed automatically.
● If the outdoor temperature falls below 57°F, the fan speed switches to MED.
● If the outdoor temperature falls below 30°F, the fan speed switches to LOW.
*1 Regardless of outdoor temperature, outdoor fan motor operates at first at HIGH speed for
23 ± 5 seconds to give the motor an initial boost.
*2 When the fan speed switches, the controller terminal’s location where line voltage comes
out (●●–●●) shifts accordingly.

10-1. Measurement of Insulation
Resistance
● The insulation is in good condition if the resistance
exceeds 2MΩ.
10-1-1. Power Supply Wires
Clamp the ground wire of the power supply wires with
the lead clip of the insulation resistance tester and
measure the resistance by placing a probe on either of
the power wires. (Fig. 1)
Then measure the resistance between the ground wire
and the other power wire. (Fig. 1)
10-1-2. Indoor 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 each terminal screw on the terminal plate. (Fig. 2)
Fig. 1
Note that the groundline terminal should be skipped for
the check.
10-1-3. Outdoor 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 each terminal screw where power supply lines are connected on
the terminal plate. (Fig. 2)
10-1-4. Measurement of Insulation
Resistance for Electrical Parts
Disconnect the lead wires of the desired electric part
from terminal plate, capacitor, etc. Similarly disconnect
the connector. Then measure the insulation resistance.
(Figs. 3 and 4)
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.

on PCB Ass’y
● Remove the PCB Ass’y from the electrical compo-
nent box. Then pull out the fuse from the PCB
Ass’y. (Fig. 5)
● Check for continuity using a multimeter as shown in
Fig. 6.
10-3. Checking Motor Capacitor
Remove the lead wires from the capacitor terminals,
and then place a probe on the capacitor terminals as
shown in Fig. 7. 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.

Installation Location
•
We recommend that this air conditioner be installed properly by
qualified installation technicians in accordance with the Installation
Instructions provided with the unit.
•
Before installation, check that the voltage of the electric supply in your
home or office is the same as the voltage shown on the nameplate.
•
Do not install this air conditioner where there are fumes or flammable
gases, or in an extremely humid space such as a greenhouse.
•
Do not install the air conditioner where excessively high heatgenerating objects are placed.
Avoid:To protect the air conditioner from heavy corrosion, avoid installing the
outdoor unit where salty sea water can splash directly onto it or in
sulphurous air near a spa.
Electrical Requirements
1. All wiring must conform to the local electrical codes. Consult your
dealer or a qualified electrician for details.
2. Each unit must be properly grounded with a ground (or earth) wire or
through the supply wiring.
3. Wiring must be done by a qualified electrician.
CAUTION
Safety Instructions
•
Read this Instruction Manual carefully before using this air conditioner.

Tips for Energy Saving
•
Block the air intake and outlet of the unit. If they are obstructed, the
unit will not work well, and may be damaged.
•
Let direct sunlight into the room. Use sunshades, blinds or curtains. If
the walls and ceiling of the room are warmed by the sun, it will take
longer to cool the room.
•
Always try to keep the air filter clean. (Refer to ‘‘Care and Cleaning’’.)
A clogged filter will impair the performance of the unit.
•
To prevent conditioned air from escaping, keep windows, doors and any
other openings closed.
