Important Safety Instructions
FOR THE INSTALLER
Read this guide before installation. The appliance must be installed by
a professional installer according to the instructions in this manual and
in accordance with all applicable regulations.
Electrical connections
• All wiring work must be done by a qualified electrician. The voltage must be
within the range of 90–110% of its rated voltage. The switch or power plug
must be kept clean.
• Before accessing the terminals, all the power circuits must be disconnected
from the power supply.
• The air conditioner must be grounded. Incomplete grounding may result
in electric shocks. Do not connect the earth wire to the gas pipeline, water
pipeline, lightning rod or telephone earth wire.
• If the air conditioner is not fitted with a supply cord and a plug, an all-pole
switch must be installed in the fixed wiring and the distance between
contacts should be no less than 3mm.
• If the air conditioner is permanently connected to the fixed wiring and has
a leakage current that may exceed 10 mA, a leakage protector must be
installed in the fixed wiring.
• An earth leakage breaker with a rated capacity of more than 1.5 times the
maximum current must be installed to avoid possible electric shocks.
• If the power supply cord is damaged, it must be replaced by the
manufacture or its service agent or a similar qualified person in order to
avoid a hazard.
• For the method of connection of the appliance to the electrical supply and
interconnection of separate components, please see the electric connection
elements chart attached to the outdoor unit.
• Make sure that after installation the power plug can easily be reached.

check for refrigerant leaks when moving the air conditioner.
Important Safety Instructions (Cont.)
Important Notice: Refrigerant Gas R-410A
This air conditioner uses the refrigerant R-410A in a closed cooling circuit.
While this coolant has zero ozone depletion potential, it is a so-called
greenhouse gas under the Kyoto Protocol and may thus contribute to
global warming, if it is released into the atmosphere. Therefore only trained
technicians with an appropriate refrigerant certificate may service the
appliance for filling or emptying.

make sure you do not create any obstacles for proper heat dispersion from
the condenser.
Install the outdoor unit:
3In a safe place and solid place
3Level, on a strong and secure installation
base and supporting frame
3In the room to be air conditioned — avoid
installation in corridors or communal
areas
3Where the air discharge and operating
sound level will not disturb neighbours
3Where the minimum clearances can be
maintained (as illustrated) for free air
circulation.
Do NOT install the indoor unit:
2Near sources of heat, steam or

Installing the Indoor Unit
• First ensure the wall is strong and solid
enough to hold the unit safety.
• Attach the installation board to the wall using
4 (+) type screws. Use a spirit level to ensure
it is in a perfectly level position vertically and
horizontally, otherwise it might cause water
drops when the unit is cooling.
• Pull out the indoor unit pipes after detaching the fixed parts on them. Connect
the interconnected pipes to the indoor unit: point to the centre of the pipe and
fasten the connection screw, at first by hand and then by wrench, until you hear
a click sound. Fastening direction is shown in the picture below.
• Drill a 70mm
diameter pipe hole
(slanting slightly
outward) at the left
or right down side
of the installation
board.
• Before installation,
confirm the direction
of the connection
pipes. Remove Board 1 and Board 2 on
the correct connecting side. Press the
connection pipes to the board gap, then
install Board 2 to the original location.
If the connection pipes are on the other
side, install them as pictured.
• The drainage pipe can be connected
to Connector 1 and Connector 2. If it
is necessary to adjust the drainage
pipe to the other connector, remove
the rubber stopper from this side
and fix the drainage pipe to it, then
fix the rubber stopper to the other
connector to block it up.
• Note: To block up the connector, use
a tool like a screwdriver to plug the
rubber stopper into the connector, as
pictured.

tube must be at the bot-
tom and its highest point
not higher than the water
basin.
Checking the Water Discharge
• For maintenance, take off the front frame according to the following steps:
• Turn the perpendicular airflow
direction handle from [ I ] to
horizontal direction.
• As shown in the picture on the
right, take off the two covers from
the front frame and then unfasten
the two fixture screws.
• Pull the front frame towards
yourself and take it off.
• To put the front frame back, turn
the perpendicular airflow direction
handle from [ I ] to horizontal, then
proceed according to the fourth
and third steps above.
• You should check whether the
front frame is firmly inside the
fixture groove on the top.
• To check the water discharge, put a cup of water into the groove and check
whether the water flows through the water discharge hole.

Installing the Outdoor Unit
• The outdoor unit must be firmly fixed so it does not fall over in strong wind.
• Install the unit on a cement base, as illustrated below.
• If the unit is to be installed in areas with strong wind, such as in coastal
areas or at places high above sea level, the outdoor unit should be installed
against a wall to ensure normal fan operation, and the blocking plate should
be used.
• Make sure the mounting surface is made of solid materials and is strong
enough to support the unit in operation. Otherwise, measures such as
reinforcement, support or vibration damping should be adopted.

Shape and form of the pipe
• Wrap up all pipe, water discharge and connection wire from top to below.
• Cover the connections and fix them with two plastic rings.
• Wrap up the pipes with tape alongside the wall and fix them to the wall with
clips. These steps are usually adopted when the outdoor unit is installed
below the indoor unit.
• In case that you want to have an
additional water discharge pipe, the
end of the pipe should be within a
certain distance towards the surface
(don’t let it drop under water, fix it onto
the wall so it won’t be swayed by wind).
• Wrap the pipes and connection wire
well from bottom to top.
• To prevent water entering the room,
wrap up the pipes that are rounded up
by the wall corners, as illustrated.
• Use clips or other fixture to fasten the pipes to the walls.

As the air conditioner is filled with the refrigerant R-410A, any air and
moisture remaining in the refrigerant system must be discharged with a
vacuum pump. (For method of using a manifold valve, refer to its operation
manual.)
1. Completely tighten the flare nuts A, B, C, D (as illustrated below) and
connect the manifold valve charge hose to a charge port of the low-
pressure valve on the gas pipe side.
2. Connect the charge hose connection to the vacuum pump.
3. Fully open the handle Lo of the manifold valve.
4. Operate the vacuum pump to evacuate. After starting evacuation, slightly
loose the flare nut of the Lo valve on the gas pipe side and check that
the air is entering. (Operation noise of the vacuum pump changes and a
compound meter indicates 0 instead of minus.)
5. After the evacuation is complete, fully close the handle Lo of the manifold
valve and stop the operation of the vacuum pump. Make evacuation
for 15 minutes or more and check that the compound meter indicates
-76cmHg (-1 x 105Pa).
6. Turn the stem
of the packed
valve B about 45°
counterclockwise
for 6~7 seconds
after the gas starts
coming out, then
tighten the flare
nut again. Make
sure the pressure
display in the
pressure indicator
is a little higher than
the atmosphere
pressure.
7. Remove the charge
hose from the Low
pressure charge
hose.
8. Fully open the
packed valve stems
B and A.
9. Securely tighten the cap of the packed valve.
