INSTALLATION LOCATION
• We recommend that this air conditioner be installed properly by qualified 
installation technicians in accordance with the Installation Instructions 
provided with the unit.
• Before installation, check that the voltage of the electric supply in your home or 
office is the same as the voltage shown on the nameplate.
ELECTRICAL REQUIREMENTS
1.All wiring must conform to the local electrical codes. Consult your dealer or a 
qualified electrician for details.
2.Each unit must be properly grounded with a ground (or earth) wire or through 
the supply wiring.
3.Wiring must be done by a qualified electrician.
SAFETY INSTRUCTIONS
• Read this Instruction Manual carefully before using this air conditioner. If 
you still have any difficulties or problems, consult your dealer for help.
• This air conditioner is designed to give you comfortable room conditions. 
Use this only for its intended purpose as described in this Instruction 
Manual. • Do not install this air conditioner where there are fumes or flammable 
gases, or in an extremely humid space such as a greenhouse.
• Do not install the air conditioner where excessively high heat-
generating objects are placed.
Avoid:To protect the air conditioner from heavy corrosion, avoid installing the outdoor 
unit where salty sea water can splash directly onto it or in sulphurous air near a 
spa.
Pull off the power plug from a receptacle, or switch off the breaker, or switch off 
the power disconnecting mean to isolate the air conditioner from the main power 
supply when not in use for a long time.
• Confirm to authorized dealer or specialist on usage of specified 
refrigerant type.
Using of refrigerant other than the specified type may cause product 
damage, burst and injury etc.
• Never touch the unit with wet hands.
• Never use or store gasoline or other flammable vapor or liquid near the 
air conditioner — it is very dangerous.
• Do not use this appliance in a potentially explosive atmosphere.
• This air conditioner has no ventilator for intaking fresh air from 
outdoors. You must open doors or windows frequently when you use 
gas or oil heating appliances in the same room, which consume a lot of 
oxygen from the air. Otherwise there is a risk of suffocation in an 
extreme case.
• Do not swallow the battery.
• After removing the battery from remote controller, keep it away from the 
reach of children. The battery can cause death by suffocation if 
swallowed.
• When inserting the battery, make sure the polarities (+ and -) are correct.
NOTE

USING THE REMOTE CONTROLLER
Temperature Display Selector
buttonThis switches the temperature display between °C and °F.
Time Display Selector buttonThis switches the time display between 24-hour time and 12-hour time.
ACL button (ALL CLEAR)Puts the remote controller into pre-operation status. Always press this button 
after replacing the batteries.
ADDRESS switch• The address switch changes to prevent mixing of signals from remote 
controller’s when two air conditioners are installed next to each other. 
Normally, the address switch is set to A. For more information, please contact 
the dealer where you made the purchase.
• Normally, the tabs on the remote controller should not be bent.
The remote controller sends the temperature signal to the air conditioner regularly at five minute intervals. 
If the signal from the remote controller stops for more than 15 minutes due to the loss of the remote 
controller or other trouble, the air conditioner will switch to the temperature sensor which is built into the 
indoor unit and control the room temperature. In these cases, the temperature around the remote 
controller may differ from the temperature detected at the air conditioner’s position.
How to Install Batteries
• The batteries last about six months, depending on how much you use the 
remote controller. Replace the batteries when the remote controller’s display 
fails to light, or when the remote controller cannot be used to change the air 
conditioner’s settings.
• Use two fresh leak-proof type-AAA alkaline batteries.
• In replacing batteries, follow the instructions as mentioned in the sub-section 
“How to Install Batteries”.
• If you do not use the remote controller more than 1 month, take out the 
batteries.
• Dispose of the used batteries at the designated location in compliance with the 
applicable local ordinances.
NOTE
1.Slide the cover in the direction indicated by the 
arrow and remove it.
2.Install two AAA alkaline batteries. Make sure the 
batteries point in the direction marked in the 
battery compartment.
3.Use a thin object such as the tip of a pen to press 
the ACL button. ACL button

USING THE REMOTE CONTROLLER (CONTINUED)
How to Use the Remote
ControllerWhen using the remote controller, always point the unit’s transmitter head directly 
at the air conditioner’s receiver.
Remote Controller Installation
PositionThe remote controller may be operated either from a non-fixed position or from a 
wall-mounted position. To ensure that the air conditioner operates correctly, do 
not install the remote controller in the following places:
• In direct sunlight
• Behind a curtain or other places where it is covered
• More than 26 ft (8 m) away from the air conditioner
• In the path of the air conditioner’s airstream
• Where it may become extremely hot or cold
• Where it may be subject to electrical or magnetic noise
• Where there is an obstacle between the remote controller and air conditioner 
(since a check signal is sent from the remote controller every 5 minutes)
Mounting the Remote
ControllerBefore mounting the remote controller, press the ON/OFF operation button at the 
mounting location to make sure that the air conditioner operates from that 
location. The indoor unit should make a beeping sound to indicate that it has 
received the signal.
To take out the remote controller, pull it forward.
When Holding the Remote
Controller• When using the remote controller and during air conditioner operation, the 
transmitter on the remote controller should be pointed towards the receiver on 
the indoor unit.
• Make sure that there are no objects between the remote controller and 
receiver which could block the signal.
