Important

Please Read Before Starting

This air conditioning system 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 this instruction booklet 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

CAUTION

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.

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.

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 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 Sys-tems)

Install the outdoor unit on a raised platform that is higher than
drifting snow. Provide snow vents.

When Connecting Refrigerant Tubing

……………………………………………………………………

• Ventilate the room well, in the event that refrigerant gas
leaks during the installation. Be careful not to allow contact
of the refrigerant gas with a flame as this 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 (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 when installation is finished. Check that no
metal scraps or bits of wiring have been left inside the unit.

CAUTION

• Ventilate any enclosed areas when installing or testing the
refrigeration system. Contact of refrigerant gas with fire or
heat can produce poisonous gas.

• Confirm after installation that no refrigerant gas is leaking. If
the gas comes in contact with a burning stove, gas water
heater, electric room heater or other heat source, it can
cause the generation of poisonous gas.

2) Selecting the Installation Site

Indoor Unit

AVOID:

ã areas where leakage of flammable gas may

be expected.

Ceiling-Mounted Type

Ceiling

ã places where large amounts of oil mist exist.
ã direct sunlight.
ã locations near heat sources which may

affect performance of the unit.

ã locations where external air may enter the

room directly. This may cause “sweating”
on the air discharge ports, causing them to
spray or drip.

ã locations where the remote control unit will

be splashed with water or affected by
dampness or humidity.

ã installing the remote control unit behind

curtains or furniture.

ã locations where the receiver in the indoor

unit is exposed to the inverter lamp light.
Faulty operation of the unit occurs.

DO:

ã select an appropriate position from which

every corner of the room can be uniformly
cooled.

ã select a location where the ceiling is strong

enough to support the weight of the unit.

Wall

Air Discharge Chamber for Top Discharge

Install the air-discharge chamber in the field when:
ã it is difficult to keep a space of minimum 2

ft. between the air-discharge outlet and
the obstacle.

ã the air-discharge outlet is facing the side-

walk and discharged hot air can annoy
the passers-by. Refer to Fig. 5.

Wind Shield for “CL” Model

IMPORTANT

It is recommended to use wind shields for
“CL” model (Fig. 6). “CL” model is designed
to use in low outdoor temperature conditions.

General

When the outdoor unit is installed in a position
exposed to strong wind (like seasonal winds
with low air temperature in winter), wind shield
must be installed on the outdoor unit.

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.

For outer dimensions of wind shield, please
see Fig. 7.

3) Electrical Wiring

General Precautions on Wiring

(1) Before wiring, confirm the rated voltage

of the unit as shown on its nameplate,
then carry out the wiring closely following
the wiring diagram.

(2) Provide a power outlet to be used exclu-

sively for each unit, and a power supply
disconnect and circuit breaker for
overcurrent protection should be pro­vided in the exclusive line.

(3) To prevent possible hazards from insula-

tion failure, the unit must be grounded.

(4) Each wiring connection must be done in

accordance with the wiring system dia­gram. Wrong wiring may cause the unit
to misoperate or become damaged.

(5) Do not allow wiring to touch the refriger-

ant tubing, compressor, or any moving
parts of the fan.

(6) Unauthorized changes in the internal

wiring can be very dangerous. The manu­facturer will accept no responsibility for
any damage or misoperation that occurs
as a result of such unauthorized changes.

(7) Regulations on wire diameters differ from

locality to locality. For field wiring rules,
please refer to your LOCAL ELECTRI­CAL CODES before beginning. You must
ensure that installation complies with all
relevant rules and regulations.

(8) To prevent malfunction of the air condi-

tioner caused by electrical noise, care
must be taken when wiring as follows:

ã The inter-unit control wiring and the remote

control wiring (option) should be wired
apart from the inter-unit power wiring.

ã It is recommended that shielding wires or

twisted pair wires be used for the remote
control and the inter-unit control wiring if
the air conditioner is installed where it is
exposed to the influence of electrical and/
or electro-magnetic noise.

11. PROCESSES AND FUNCTIONS

(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. 8 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 1 °F above the set temperature T˚, (T ˚+1 °F):

Compressor ➞ ON

❑ Thermo OFF: When the room temperature is equal to or below the set temperature T˚:

(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.
