Introduction

Preface

LG Electronics Inc.

Air Conditioning Division

New era brings more sophisticated and advanced buildings which in turn demands for specialized and optimized direct

expansion air conditioning systems. Also energy efficiency, environment friendliness, low noise and low maintenance are

the features which are essential for these systems.

As a part of vertical integration LG makes all the key components in house, which gives us an edge to make better and lat-

est technology products with best quality in optimized time.

Ceiling cassette installed in the ceiling is popularly used for various places. It has nice outlook and is equipped with many

special features.

This engineering product data book incorporates information about the product itself, and installation, designing for ceiling

cassette.The comprehensive study of this book will improve your knowledge about the system and its application in detail.

Ceiling Cassette

Step by step air conditioner selection process (reference)

(1) Calculate or obtain the maximum heat load for the area(s) to be air conditioned

(2)

(3)

(4)

1. Air conditioners should not be installed in areas where corrosive gases, such as acid gas

Make referene to the Multi PDB (P/No. 3828A20576B)

or alkaline gas, are produced.2. If the outdoor unit is installed close to the sea shore, direct exposure to the sea breeze

should be avoided and choose an outdoor unit with anti-corrosion treatment.

Features 6CST2-01A

Ceiling Cassette

Wide Jet Air Flow

Improved wide and narrow vane will provide comfortable

temperature distribution without air flow dead zone.

High head drain pump(800mm)

Built-in drain pump drains out water automatically.

A standard drain-head height of up to 800 mm is pos-

sible, providing an ideal solution for perfect water

drainage.

Function to Control the Air Volume by

Ceiling Height

Control of the air intensity has been made possible by

employing a height-control algorithm for the interior fan.

Two Thermistor Control

There may be a significant difference between the tempera-

ture taken at the installed product and indoor temperature.Two thermistor control provides option to control tempera-

ture by referring any of the two temperatures.With the help

of the slide switch at the back of the LCD wired remote con-

troller,selection of the desired thermistor for controlling the

unit can be done.One thermistor is in the Indoor unit &the

other one is in the LCD wired remote.

4 Vane Independent Operation

Vane angle control satisfies both users who like direct wind

or indirect wind.And also it prevents cold air draft.

- This function can be controled with new wired remote con-troller

Group control

1) Operation summary

- Where several products are linked, one specific control

device can control a specific number of products.

2) Specific operation

- Connecting line is linked to each of the indoor equipments

for communication. A specific control device is connected

to each of them and this control device can control the

same function.

- Group control function is enabled by cutting an optional

jump wire in the wired remote control. At this time, themain system will not respond in order to prevent data colli-

sion.

- While executing group control command, use the random

data(0-3minutes) in the main body of indoor equipment for

limiting starting current.

- Control device can control up to 16 indoor equipments.

Features6CST0-01A

Ceiling Cassette

Zero power consumption in standby modeby adopting SMPS (Switching mode power

supply)

Power waste due to standby mode

- Power is wasted if a plug is connected to an outlet even

though the appliance is turned off.

Development of super power-saving SMPS(Switching Mode Power Supply)

- Zero standby power by reducing 90% of standby power.

- No need to pull out every plug when system is not in use.

Low noise with 3-dimensional turbo fan

The most advanced low-noise design.The adoption ofturbo-fan and round type give the most quiet operation.

Built-in drain pump

A standard drain-head height of up to 800mm is possible,

creating the ideal solution for perfect water drainage.


According to the height of the installation, it provides vari-

ability of indoor fan motor speed.

If the height of installation is low then you can adjust low

rpm of indoor fan motor. On the other hand if the height of

the installation is high you can adjust high speed of indoorfan motor. Selection of speed can be done by slide switch

at the back of the LCD wired remote controller.

ex: If ceiling height of 2.7-3m(taken as standard for the product) is

exceeded, then the slide switch is iperated in the high mode discharg-ing air at a high volume rate and when below 2.7m, the switch isadjusted to discharge at a lower volume rate.

Sound pressure level

Notes:

- Sound measured at 1.5m away from the center of the unit.- Data is valid at free field condition.- Data is valid at nominal operation condition.

- Reference accoustic pressure 0dB=20Pa.- Sound level will vary depending on a range of factors such asthe construction(acoustic absorption coefficient) of particular

room in which the equipment is installed.- The operating conditions are assumed to be standard.
