Preface
LG Electronics Inc.
Air Conditioning & Energy Solution Company
Thank you very much for your special patronage of LG air conditioners.
LGʼs "Roof Top or Single Package" is an ideal choice when we talk about high load applications.
As the name Roof Top signifies, this unit is generally installed on the top of the roof. Also the Single Package signifies that
both condenser and evaporator are enclosed in a single body(same as window type). The unit is used along with ducts and
has flexible air flow as per installation conditions. The air flow can be horizontal or vertically downward which offers wider
flexibility in the field applications.
This unit is ideal for Single story and Double story houses as they offer high static pressure.
With its easy installation and simple control system, this product is suitable for Factories, Shopping malls, Multiplex, Hotels
etc.
A lot of information regarding the design & installation of this system is provided in this edition. This new product series con-
tains data on the same pattern.
Please utilize all the information for conducting your business efficiently.
Make sure the specification, dimensions and other technical data are same as provided in enginering data book before you
start the project.
We look forward to your continuing support.

• Safety Condenser Fin Guard
• Forklift Base rail
• Easy access Panel.
nReliablity
• Time delay relay is standard component
• Low pressure Switch is standard component
• LG Scroll compressor with internal high-pressure & over-
current protector
• Strainer is adopted
• Durable painting steel cabinet

• Direct-drive PSC condenser fan Motor
Easy Installation, Maintenance & Service
The unit can be installed outside to save valuable indoor space or where no ceiling space is available. Install
the unit on the ground or on the roof. This means that the installation is totally flexible depending on your
requirements.
Since the unit has not been split into two, maintenance is easy, especially because all access panels are on the
same side of the unit and all wiring inside has been colour coded.
Additional functions available with duct system
All units come standard in Reverse Cycle, however electric heating can be added (Electric Heating provided
by Specialist Dealers). You have complete control over the fresh air input, amount of air purification and
zone controls (extras provided by Specialist Dealers), all using the powerful LG control system.
Typical Installation
①Roof Jack Installation
②Slab on Ground Installation

3. Features & Benefits
Single Package

Single Package
Auto Restart Operation :
- Whenever there is electricity failure the system shuts off and resumption of the power, unit will start in the
same mode as prior to the power failure. Memorized condition are on / off condition, operating mode (cool-
ing/heating), set temperature and fan speed.
LCD Wired Remote Control :
- It can control all the functions of the unit. You can
check/set temperature, change operation mode, set
timer & also diagnose the error of the unit. It also
has the weekly program.
Two Thermistor Control(Return Air
Control):(Accessory)
- There may be a significant difference between the return air temperature in the duct and the room tempera-
ture. Return air sensing tempeaturee is designed to control temperature more accurately by applying addition-
al thermistor which senses the return air temperature inside the duct specially.
After selecting the duct thermistor, which is connected to the main PCB, the room temperature measurement
by LCD wired remote control thermistor is neglected. It helps to control the room temperature more accurate-
ly.(Thermistor is a field-installed accessory)
Group Control : (Accessory)
- It enables to control max of 16 units with the help of
one wired remote controller. All the units will follow
same setting of temperature & other sub functions.

Defrost / Deicing :
- In the heating mode, it prevents the ice formation on the outdoor unit. The heating cycle is reversed to the cooling
cycle to defrost the evaporator pipe of the outdoor unit. While defrost cycle, the compressor is on and indoor fan, out-
door fan and 4-way valve are off.
Hot Start Function :
- During starting of the unit in the heating mode it prevents cold air blow from the unit.It starts the indoor fan only after
indoor unit pipe temperature reaches a preset value.
Time Delay Relay :
- It delays restarting of the compressor by three minutes thereby preventing damage to the compressor .
Self Diagnosis Function :
- This function provides diagnosis of the unit. An error code will be displayed on the LCD wired remote controller &
diagnosis can be done as per the code indication.The
same is also printed on key cover of the LCD wired
remote controller.
Central Control :(Accessory)
- It enables to control 16 x 8 = 128 units with the help of 8
controllers. All units can be put on and off from one
Central Room.For Setting Temperature, Fan Speed and
other sub functions, access the LCD wired remote con-
troller of each unit.

Child Lock Function :
- It prevents the children or others from tampering with the control
buttons.
Press button repeatedly until the is flashing.
If moving to 'setup' icon area by using button, 'setup' icon
blinks, and child lock function is setup if pressing button at
that time.
When cancelling lock function, if moving to 'cancel' icon by
pressing button and then, pressing button, child lock
function is cancelled. Press button to exit.
hAfter setup, it automatically gets out of setup mode if there is
no button input for 25 seconds.
hWhen exiting without pressing set button, the manipulated
value is not reflected.

Weekly Program :
- It provides on / off schedule of operation for a period of one
week.
Wireless Remote Control: (Accessory)
- It provides ease of control.
Electric Heater: (Accessory)
- Electric Heater can be used to provide heat in addition to cycle
heat. It also provides quick heating. It can also work as a stand
alone heater with only fan operation.
Fire Alarm Function:
- By purchasing a fire alarm locally, installation of the fire alarm is
possible.In case of any fire, alarm will sound and the unit will be
completely stopped.
Energy Saving Gold Fin:
- Single Package Heat Exchanger fins are coated with anticorro-
sive & hydrophilic layers. It prevents the corrosion of heat
exchanger. Fins remains as new even after long time and main-
tains efficiency of heat exchanger. Saves power & maintenance
Cost.
Soft Start Function:
- All single package air conditioners has soft start function i.e.
Indoor fan, outdoor fan & compressor start in sequence to pre-
vent overcurrent during starting.
