● Observe the rules and regulations of the electrical installation and the methods described in the installation
manual when dealing with the electrical work. Use cables which are offi cially approved in your country.
Be sure to use the specifi ed circuit. A short circuit and fi re may occur due to the use of low quality wire
or improper work.
● Be sure to use the specifi ed cables for connecting the indoor and outdoor units. Please ensure that
the connections are tight after the conductors of the wire are inserted into the terminals to prevent the

!
A circuit breaker or fuse must be installed. Without a circuit breaker or fuse the danger of electric shock exists.
●
The external switch shall be incorporated to completely disconnect from power supply. It should disconnect all poles, and a contact
separation of at least 4/32" (3mm) must be present.
Do not install the unit near a location where there is fl ammable gas. The outdoor unit may catch fi re if fl ammable
●
gas leaks around it.
Do not install the indoor unit in a machine shop, kitchen and laundry rooms when vapor from oil or its mist fl ows to
●
the indoor unit. The oil will deposit on the heat exchanger, thereby reducing the indoor unit performance and may
deform and in the worst case, break the plastic parts of the indoor unit.
Please ensure smooth fl ow of water when installing the drain hose.
●
Piping shall be suitable supported with a maximum spacing of 3-9/32ft (1m) between the supports.
●
Selecting the installation location: Suitable location that will reduce the impact from rain and direct sun that may affect the unit
●
performance. Besides that, ventillation must be good and clear of obstruction.
The air blown out of the unit should not point directly to animals or plants.
●
The clearances of the unit from top, left, right and front are specifi ed in fi gure below. At least three of the above sides must be
●
open air.
Be sure that the hot air blown out of the unit and noise do not disturb the neighbourhood.
●
Do not install at a location where there is fl ammable gas, steam, oil and smoke.
●
The location must be convenient for water drainage.
●
Place the outdoor unit and its connection wire at least 3-9/32ft (1m) away from the antenna or signal line of television, radio or
●
telephone. This is to avoid noise interference.
Do not install outdoor unit facing strong wind direction. It may damage the fan motor.
●
Do not install the outdoor unit in a place where small animals may build their nests. If small animal goes inside the unit and touches
●
the electrical parts, failure of the unit, smoke or fi re may be caused. Request your customer to keep the surrounding of the unit is
clean.
Safely dispose all packing and transportation materials in accordance with federal/state/local laws orordinances. Packing materials
●
such as nails and other metal or wood parts, including plastic packing materials used for transportation may cause injuries or death
by suffocation.
The maximum number of pieces of equipment permitted to be stored together will be determined by local regulations. Storage package
●
protection should be constructed in such a way that mechanical damage to the equipment inside the package will not cause a leak
of the REFRIGERANT CHARGE.

other sources of ignition. Else, it may explode and cause injury or death.
The Choice of Mounting Site
(Please note the following matters and obtain permission from customer before installation).
WARNING
!
● The Outdoor unit must be mounted at a location which can
support heavy weight. Otherwise, noise and vibration will
increase.
! CAUTION
● Do not expose the unit under direct sunshine or rain. Besides,
ventilation must be good and clear of obstruction.
● The air blown out of the unit should not point directly to
animals or plants.
● The clearances of the unit from top, left, right and front are
specifi ed in Figure 1. At least 3 of the above sides must be
open air.
● Be sure that the hot air blown out of the unit and noise do
not disturb the neighbourhood.
● Do not install at a location where there is fl ammable gas,
steam, oil and smoke.
● The location must be convenient for water drainage.
● Place the Outdoor unit and its connecting cord at least
3.28ft(1m) away from the antenna or signal line of television,
radio or telephone. This is to avoid noise interference.
● Do not install outdoor unit facing strong wind direction. It may
damage the fan motor.
● Do not install the outdoor unit in a place where small animals
may build their nests. If small animal goes inside the unit
and touches the electrical parts, failure of the unit, smoke
or fi re may be caused. Request your customer to keep the
surrounding of the unit is clean.
Please mount the outdoor unit on stable ground to prevent vibration and increase of noise level.

CONDENSED WATER DISPOSAL OF OUTDOOR UNIT
There are holes on the base of Outdoor unit for condensed water to exhaust.
●
In order to fl ow condensed water to the drain, the unit is installed on a stand or a block so that the unit is 3-15/16"
●
(100mm) above the ground as shown fi gure. Join the drain pipe to one hole.
At fi rst insert one portion of the hook to the base (Portion A), then pull the drain pipe in the direction shown by the arrow
●
while inserting the hook into the base. After installation, check whether the drain pipe cling to the base fi rmly.
BASE
DRAIN PIPE
When Using and Installing In Cold Areas
When the air conditioner is used in low temperature and in snowy conditions, water from the heat exchanger may freeze on
the base surface to cause poor drainage. When using the air conditioner in such areas, do not install the bushings. Keep a
minimum of 9-27/32" (250mm) between the drain hole and the ground. When using the drain pipe, consult your sales agent.
For more details, refer to the installation Manual for Cold Areas.
