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.

Introduction:

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

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.

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.
