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
CAUTION
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.
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 ordeath.
• Ground the unit following local electrical codes.
• Connect all wiring tightly. Loose wiring may cause
overheating at connection points and a possible fire
hazard.
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 servicepersons 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.
This manual will help you understand and service the air conditioner. To help you find the information you
need, we have divided it into 5 main sections. Each section is divided into chapters with charts, tables and
explanations to help you find and repair problems.
❑Section 1: Specifications, tells you about the physical and electrical make up of the unit, as
well as its heating and cooling capacities. Look in this section to find the correct values for
components and functions.
❑Section 2: Processes and Functions, explains each different part of the cooling and
heating cycle, and how each control function reacts to changing conditions to keep the room
at the set temperature range.
❑Section 3: Electrical Data, which has fold-out schematic and wiring diagrams so you can
find the parts you need to check when something is wrong, and see how they should be
connected.
❑Section 4: Service Procedures, has two main parts, a
the specific component to replace or adjust, and a chapter with specific procedures and
values to guide you in checking the electrical components in the unit.
❑Section 5: Instruction Manual, is the same manual the user will have, and it contains
general information about how to set and use the features of this particular air conditioner.
Knowing this information will help you tell the owner how to use and care for this air
conditioner, and also help you install and set the unit correctly.
WHAT IS IN THIS MANUAL

HOW TO USE THIS MANUAL
You can use this manual both as a
construction of this unit, and as a source of information to help you set up and maintain the unit.
When this unit is not working properly, and the cause is not known, you can use the procedures in
Section 3: Servicing Procedures to find the problem, fix it, and restore the unit to its proper functioning.
This air conditioner has many helpful self diagnostic features to help you identify problem areas quickly.
So you will be ready when a problem happens, we suggest you look this manual over and become familiar
with it by following these steps:
1.Look at the TABLE OF CONTENTS to get an idea of what is in this manual and where to
find it.
2.Look at the chapter about TROUBLE SHOOTING, so you are familiar with the way the flow
charts work. They are designed to guide you quickly through the possible causes for each
kind of problem that is likely to happen to the Unit. Particularly read the introduction to this
section, and the parts about the self-diagnosis and error codes which show on the display.
3.Look at the chapter about CHECKING ELECTRICAL COMPONENTS. You already know
about most of these procedures. This chapter gives you the specific values and methods for
these components. If you don’t know some of these procedures, you can easily learn them
here.
4.Read the Instruction Manual! The Instruction Manual is included here because it helps you
help the user to set the temperature controls properly and know how to take care of any
simple problems that may happen, as well as know when to call for service. The Instruction
Manual also has illustrations, care, and installation information not found in the rest of the
service manual. It is short, and if you read it carefully, you will be able to answer the
customers questions easily, and also know the most efficient ways for setting times and
temperatures.
