Decide the location for piping after sorting out the different types of
G
pipe available.
When removing side cover, please pull the handle after undoing the

CONDENSED WATER DISPOSAL OF OUTDOOR UNIT
There are holes on the base of Outdoor unit for condensed
water to exhaust.
In order to flow condensed water to the drain, the unit is installed on a
stand or a block so that the unit is 100mm above the ground as shown
figure. Join the drain pipe to one hole.
At first 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 firmly.

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 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.

WARNING
G
The naked part of the wire core should be 10 mm and fix
it to the terminal tightly. Then try to pull the individual wire
to check if the contact is tight. Improper insertion may
burn the terminal.
Be sure to use only power cables approved from the
G
authorities in your country. For example in Germany: Cable
type: NYM 3x1.5mm
2
, (fuse = 20A time delay)
Please refer to the installation manual for wire connection
G
to the terminals of the units. The cabling must meet the
standards of electrical installation.
G
There is a AC voltage of 240V between the L and N
terminals. Therefore, before servicing, be sure to remove
the plug from the AC outlet or switch off the main switch.

Insulation And Maintenance Of Pipe Connection
G
The connected terminals should be completely sealed with
heat insulator and then tied up with rubber strap.
G
Please tie the pipe and power line together with vinyl tape as
shown in the figure showing the installation of Indoor and
Outdoor units. Then fix their position with holders.
To enchance the heat insulation and to prevent water
G
condensation, please cover the outdoor part of the drain hose
and pipe with insulation pipe.
G
Completely seal any gap with putty.

CAUTION
!
G
Please use a new socket. Accident may occur due to the use of old
socket because of poor contact.
G
Please plug in and then remove the plug for 2 – 3 times. This is to
ensure that the plug is completely plugged into the socket.
G
Keep additional length for the power cord and do not render the
plug under external force as this may cause poor contact.
G
Do not fix the power cord with U-shape nail.

WARNING
G
Be sure that the hooks (6 places) are
plugged in.
Otherwise, water leakage may occur and
this causes short circuit or faults.
Checking for the electric source
and the voltage range
G
Before installation, the power source must be checked and
necessary wiring work must be completed. To make the
proper wiring capacity, use the wire gauges list below for
the lead-in from a pole transformer and for the wiring from a
switch board of fuse box to the outlet in consideration of the
locked rotor current.

To operate the remote controller at its holder, please ensure
that the unit can receive signal transmitted from the controller
at the place where the holder is to be fixed. The unit will beep
when signal is received from the remote controller. The signal
transmission is weaken by the fluorescent light. Therefore,
during the installation of the remote control holder, please
switch on the light, even during day time, to determine the
mounting location of the holder.
The controller must
be hooked onto the
hook at the lower
