Prior to Operation
1. Contact an installation specialist for installation.
2. Plug in the power plug properly.
3. Use a dedicated circuit.
4. Do not use an extension cord.
5. Do not start/stop operation by plugging/unplugging the power cord.
6. If the cord/plug is damaged, replace it with only an authorized replacement
part.
1. Being exposed to direct airflow for an extended period of time could be
hazardous to your health. Do not expose occupants, pets, or plants to direct
airflow for extended periods of time.
2. Due to the possibility of oxygen deficiency, ventilate the room when used
together with stoves or other heating devices.
3. Do not use this air conditioner for non-specified special purposes (e.g.
preserving precision devices, food, pets, plants, and art objects). Such usage
could damage the items.
1. Do not touch the metal parts of the unit when removing the filter. Injuries can
occur when handling sharp metal edges.
2. Do not use water to clean inside the air conditioner. Exposure to water can
destroy the insulation, leading to possible electric shock.
3. When cleaning the unit, first make sure that the power and breaker are turned
off. The fan rotates at a very high speed during operation. There is a
possibility of injury if the unit’s power is accidentally triggered on while
cleaning inner parts of the unit.
For repair and maintenance, contact your authorized service dealer.

Installation
NOTICE
How to Install the Unit
1. To prevent vibration and noise, make sure the
unit is installed securely and fir mly
2. Install the unit where the sunlight does not
shine directly on the unit.
3. The outside of the cabinet must extend outward
for at least 356mm and there should be no
obstacles, such as a fence or wall, within 508mm
from the back of the cabinet because it will
prevent heat radiation of the condenser.
Restriction of outside air will greatly reduce the
cooling efficiency of the air conditioner.
All side louvers of the cabinet must remain exposed to the outside of the str ucture.
4. Install the unit at a slight incline so the bac k is slightly lower than the front(about 6.4mm).
This will force condensed water to flow to the outside.
5. Install the unit with the bottom about 762mm ~1524mm above the floor level.
