WARNING: Indicates a potentially hazardous situation

which, if not avoided, could result in death or serious injury.

CAUTION: Indicates a potentially hazardous situation

which, if not avoided, may result in minor or moderate injury.

It may also be used to alert against unsafe practices and

where property-damage-only accidents could occur.

Read this entire manual before beginning installation

procedures.

Bodily injury can result from high voltage electrical

components, fast moving fans. For protection from these

inherent hazards during installation and servicing, the

electrical supply must be disconnected.

If operating checks must be performed with the unit

operating, it is the technicians responsibility to recognize

these hazards and proceed safely.

CAUTION

WARNING

Ask your dealer for installation of the air conditioner.

Incomplete installation performed by yourself may result in a

water leakage, electric shock, and fire.

Ask your dealer for improvement, repair, and

maintenance.

Incomplete improvement, repair, and maintenance may

result in a water leakage, electric shock, and fire.

In order to avoid electric shock, fire or injury, or if you

detect any abnormality such as smell of fire, turn off the

power supply and call your dealer for instructions.

Never replace a fuse with that of wrong rated current or

other wires when a fuse blows out.

Use of wire or copper wire may cause the unit to break down

or cause a fire.

Do not insert fingers, rods or other objects into the air

inlet or outlet.

When the fan is rotating at high speed, it will cause injury.

Never use a flammable spray such as hair spray,

lacqueror paint near the unit.

It may cause a fire.

Never inspect or service the unit by yourself.

Ask a qualified service person to perform this work.

Do not dispose this product as unsorted municipal

waste.Collection of such waste separately for special

treatment is necessary.

Keep far away from high-frequency equipment.

Keep away from the following places:

A place where it is full of oil gas; places where salty air

surrounding(near the coast); a place where is caustic gas(the

sulfide in hotspring). Location in the folling places may cause

malfunction or shorten the life span of the manchine.

In the cace of extremely strong wind, please prevent the

air from flowing backwards into the outdoor unit.

Snow canopy is necessary in sonwfall places on the

outdoor unit. Please consult the local dealer for details.

In the frequent

thunderstruck place, lightning proof

actions should be taken.

To prevent refrigerant leak, contact your dealer.

When the system is installed and runs in a small room, it is

required to keep the concentration of the refrigerant, if by any

chance coming out, below the limit. Otherwise, oxygen in the

room may be affected, resulting in a serious accident.

The refrigerant in the air conditioner is safe and normally

does not leak.

If the refrigerant leaks in the room, contact with a fire of a

burner, a heater or a cooker may result in a harmful gas.

Turn off any combustible heating devices, ventilate the

room, and contact the dealer where you purchased the

unit.

Attaching horizontal ductwork to unit

All conditioned air ductwork should be insulated to minimize

heating and cooling duct losses. Use a minimum of two (2)

inches of insulation with a vapor barrier. The outside ductwork

must be weatherproofed between the unit and the building.

When attaching ductwork to a horizontal unit, provide a flexible

watertight connection to prevent noise transmission from the

unit to the ducts. The flexible connection must be indoors and

made out of heavy canvas.

Attaching downflow ductwork to roof curb

Supply and return air flanges are provided on the roof curb for

easy duct installation. All ductwork must be run and attached to

the curb before the unit is set into place.

Follow these guidelines for ductwork construction:

Connections to the unit should be made with three-inch canvas

connectors to minimize noise and vibration transmission.

Elbows with turning vanes or splitters are recommended to

minimize air noise and resistance.

The first elbow in the ductwork leaving the unit should be no

closer than two feet from the unit, to minimize noise and

resistance.

Minutes delay for the compressor start-up

At the beginning of energizing or after the stop of the

compressor, 3-minutes delay will be taken to start the

compressor.

When switchover between cooling/heating mode, the

compressor stops automatically.

Compressor discharge gas temperature switch protection

When compressor discharge gas temperature

discharge gas temperature switch will be closed. At the same

time, the corresponding compressor will be shut off. The

ON/OFF signal and high-pressure protection signal should be

connected together.

Reverse phase protection relay

The reverse phase protection relay will make the compressor

not start, when the power source is incorrectly connected.

The checking of phase’ order is just carried out at the first time

of electrifying. If malfunction happens then the checking will be

going on until the order of phase is right, and the E0 will be

displayed on the board. If there is no problem in the first

checking, then it will be omitted.

High pressure and low pressure protection

The ON/OFF of high pressure and low pressure will be

installed separately around inlet pipe, and both are connected

to Main Control Board. The ON/OFF of high pressure will be

off when the pressure is higher than 425Psi. The ON/OFF of

low pressure will be off when lower than 7Psi.
