Operation Details
(1) The function of main control
1. Time Delay safety Control
•3min The compressor is ceased for 3minutes to balance the pressure in the refrigeration cycle.
(Protection of compressor)
•30sec The 4-way valve is ceased for 30sec. to prevent the refrigerant-gas abnormal noise when the Heating
operation is OFF or switched to the other operation mode while compress is off.
While compressor is running, it takes 3~5 seconds to switch.
2. Soft-Dry Operation
•The indoor fan speed is automatically set to the low, so the shift of the indoor fan speed is impossible because of
already being set to the best speed for Dry Operation by Micom Control.
3. Cooling Mode Operation
•When selecting the Cooling( ) Mode Operation, the unit will operate according to the setting by the remote con-
troller and the operation diagram is as following

A point; While the indoor Heat-Exchanger temperature is higher than 40°C fan operates at low speed, when
it becomes lower than 40˚C fan stops.
B point; When the indoor Heat-Exchanger temperature is higher than 42°C, fan operates at seleted fan
speed, when it becomes lower than 39°C, the fan operates at low speed.

6. Defrost Control
•Defrost operation is controlled by timer and sensing the outdoor piping temperature.
•The defrost starts only when the outdoor pipe temperature falls below -6°C after 45 minutes passed from starting
of heating operation.
•Defrost ends after 10 minutes passed from starting of defrost operation or when the outdoor pipe
temperature rises over 12°C even if before 10 minutes.
7. Auto Restarting Operation
•When the power is restored after a sudden power failure while in appliance operation, the mode before the
power failure is kept on the memory and the appliance should be on the automatically operates in the mode on
the memory.
•Operation Mode that is kept on the memory
- State of Operation ON/OFF
- Operation Mode/Setting Temp/Selected Airflow Speed
•If no input by the remote controller within 7 hr after the appliance operates by the Auto Restarting operation,
the appliance is forced to stop at the moment of 7-hr elapse.
8. Self-Diagnosis Function
•'CHECK' will flash in the remote controller display when a problem occurs. Then please contact your dealer.
•Correct the accident point as shown in the table below before restarting operation.
•During the normal operation 'CHECK' won't be displayed in the remote controller.

Installation of Indoor, Outdoor Unit
1. Selection of the best location
1) Indoor unit
Select location
Install the air conditioner in the location that satis-
fies the following conditions.
•The place shall easily bear a load exceeding four
times the indoor unit’s weight.
•The place shall be able to inspect the unit as the
figure.
•The place where the unit shall be leveled.
•The place shall allow easy water drainage.(Suit-
able dimension “H”is necessary to get a slope to
drain as figure.)
•The place shall easily connect with the outdoor
unit.
•The place where the unit is not affected by an
electrical noise.
•The place where air circulation in the room will be
good .
•There should not be any heat source or steam
near the unit.
2) Outdoor unit
•If an awning is built over the unit to prevent
direct sunlight or rain exposure, be careful that
heat radiation from the condenser is not restrict-
ed.
•There should not be any animals or plants which
could be affected by hot air discharged.
•Ensure the spaces indicated by arrows from the
wall, ceiling, fence or other obstacles.

•If 36K Model is installed at a distance of 15m, 700g of refrigerant
should be added (15-5) x 70g = 700g.
•Capacity is based on standard length and maximun allowance
length is on the basis of reliability.
NOTE:
• Throughly study the following installation locations:
1. In such places as restaurants and kitchens, considerable amount of oil steam and flour adhere to the
fan, the fin of the heat exchanger, resulting in heat exchange reduction, spraying, dispersing of water
drops, etc.
In these cases, take the following actions:
• Make sure that the ventilation fan for smoke-collecting hood on a cooking table has sufficient capac-
ity so that it draws oily steam which should not flow into the suction of the air conditioner.
• Make enough distance from a cooking room to install the air conditioner in such a place where it
may not suck in oil steam.
2. Avoid installing air conditioner in such circumstances where cutting oil mist or iron powder is in sus-
pension in factories, etc.
3. Avoid places where inflammable gas is generated, flows in, is stored or vented.
4. Avoid places where sulfurous acid gas or corrosive gas is generated.
5. Avoid places near high frequency generators.
3) Piping length and the elevation

■Installation of Unit
Install the unit above the ceiling correctly.
•Apply a joint-canvas between the unit and duct to
absorb unnecessary vibration.
•Apply a filter Accessory at air return hole.
•Install the unit leaning to a drainage hole side as
a figure for easy water drainage.
•A place where the unit will be leveled and that
can support the weight of the unit.
•A place where the unit can withstand its vibration.
•A place where service can be easily performed.

•Select places that are not splashed with water.
•Select control position after receiving customer approval.
•The room temperature sensor of the thermostat for temperature control is built in the indoor unit.
•This remote controller equipped with liquid crystal display. If this position is higher or lower, display is difficult
to see.(The standard height is 1.2 ~ 1.5m high)
Routing of the remote control cord
•Keep the remote control cord away from the refrigerant piping and the drain piping.
•To protect the remote control cord from electrical noise, place the cord at least 5cm away from other power
cables (audio equipment, television set, etc.)
•If the remote control cord is secured to a wall, provide a trap at the top of the cord to prevent water droplets
from running.
