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.  
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.  
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.  
Never use or store gasoline or other flammable vapor or liquid near  
the air conditioner — it is very dangerous.  
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.  
CAUTION  
Do not turn the air conditioner on and off from the power mains  
switch. Use the ON/OFF operation button.  
Do not stick anything into the air outlet of the outdoor unit. This is  
dangerous because the fan is rotating at high speed.  
Do not let children play with the air conditioner.  
Do not cool the room too much if babies or invalids are present.

Special Remarks  
‘‘DRY’’ ( ) Operation  
How it works?  
Once the room temperature reaches the level that was set, the unit  
repeats the cycle of turning on and off automatically.  
During DRY operation, the fan speed is automatically set to LOW or  
VERY LOW; the fan speed then switches back and forth between LOW  
(for 20 seconds) and VERY LOW (for 10 seconds).  
‘‘DRY’’ operation is not possible if the indoor temperature is 59 °F or  
less.  
In the event of power failure, the unit will stop. When the power is  
turned on again, the unit restarts within five minutes.  
Power failure

Clicking Sound  
Clicking sound is  
heard from the air  
conditioner  
In cooling and drying operation, any plastic parts may expand or shrink  
due to a sudden temperature change. In this event, a clicking sound  
may occur. This is normal, and the sound will soon disappear.  
The remote control unit sends the setting condition to the air  
conditioner regularly at five minute intervals.  
Remote Control Unit  
IMPORTANT  
When this unit is combined with the CL1852 outdoor unit, set the indoor  
airflow to medium or high when the outdoor temperature drops below  
32 °F to prevent condensation from forming at the indoor unit.

Adjusting the Airflow Direction  
1. Horizontal  
The horizontal airflow can be adjusted by moving the vertical vanes with  
your hands to the left or right.  
When the humidity is high, the vertical vanes should be in the front  
position during the cooling or drying operation. If the vertical vanes are  
positioned all of the way to the right or left, condensation may begin to  
form around the air vent and drip down.  
CAUTION  
2. Vertical  
The vertical airflow can be adjusted by moving the flap with the remote  
control unit. Do not move the flap with your hands. Confirm that the remote  
control unit has been turned on. Use the FLAP button to set either the  
sweep function or one of the six airflow direction settings.

Care and Cleaning  
1. For safety, be sure to turn the air conditioner off and also to  
disconnect the power before cleaning.  
2. Do not pour water on the indoor unit to clean it. This will damage  
the internal components and cause an electric shock hazard.  
Casing and Grille  
(Indoor Unit)  
Clean the casing and grille of the indoor unit with a vacuum cleaner brush,  
or wipe them with a clean, soft cloth.  
If these parts are stained, use a clean cloth moistened with a mild liquid  
detergent. When cleaning the grille, be careful not to force the vanes out of  
place.  
CAUTION  
1. Never use solvents, or harsh chemicals when cleaning the indoor  
unit. Do not wipe the plastic casing using very hot water.  
2. Some metal edges and the fins are sharp and may cause injury if  
handled improperly; be especially careful when you clean these  
parts.  
3. The internal coil and other components of the outdoor unit must  
be cleaned every year. Consult your dealer or service center.

purchased separately. The first time that you buy the air clean filter, it is  
necessary to get the STK-ARF4B model with frame. When changing the  
filter subsequently, it is only necessary to replace the filter itself (model  
STK-F4B). Do not throw away the filter frame.

The air cleaning filter cannot remove harmful gases or vapors nor ventilate  
air in the room. You must open doors or windows frequently when you use  
gas or oil heating appliances. Otherwise there is a risk of suffocation in  
extreme cases.

Tips for Energy Saving  
Do not  
Block the air intake and outlet of the unit. If they are obstructed, the  
unit will not work well, and may be damaged.  
Let direct sunlight into the room. Use sunshades, blinds or curtains. If  
the walls and ceiling of the room are warmed by the sun, it will take  
longer to cool the room.  
Do  
Always try to keep the air filter clean. (Refer to ‘‘Care and Cleaning’’.)  
A clogged filter will impair the performance of the unit.  
To prevent conditioned air from escaping, keep windows, doors and any  
other openings closed.
