Welcome to the TOSOT Direct Family!
We’re extremely happy to welcome you as a new member of our family! Please
read the tips below before using your product for the first time.
1. The split-type air conditioner is a heavy object, which needs two or more people
to lift and install. Failure to do so could result in injury or other accidents.
2. Allow the unit to sit upright for at least 3-4 hours before powering on. Shipping
carriers may set the unit on its side, which causes the refrigerant to pool in
certain areas. Standing the unit upright for 3-4 hours allows the refrigerant to
move freely within the coils.
3. Some parts with sharp edges may cause injury, so gloves are highly
recommended for unpacking and installing.
4. Run the unit continuously for 24 hours after installation. This allows the unit to
work out any “kinks” that may have resulted during shipping from our factory to
your
doorstep.
5. If you have any problems with your product, please send us an email before
submitting a return request, as there might be a simple solution for your issue.

Indoor Unit Installation
1. Select an Installation Site
Refer to the following
diagram to ensure proper
distance from walls and
ceiling:
Minimum 6 in (15 cm)
Minimum
6 in (15 cm)
Minimum 98.5 in (250cm)
Minimum
6 in (15 cm)
Before installing the indoor unit, you need to check the label on the
product box and make sure that the model number of the indoor unit
matches the model number of the outdoor unit.
An appropriate install location should follow
these standards:
Ɣ Convenient drainage for water condensation.
Ɣ Convenient to connect the outdoor unit
Ɣ Near a properly-grounded wall outlet
Ɣ Not easily accessible for children.
Ɣ Strong enough to support the weight of the unit.
Ɣ Away from other electric appliances (e.g. TV, radio, computer, etc.)
Ɣ Not near fluorescent lamps.
DO NOT install the unit in the following locations:
Ɣ Near strong heat sources or where vapors, flammable or explosive gas,
or volatile objects can be spread in the air.
Ɣ Near high-frequency devices such as welding machines or medical equipment.
Ɣ Corrosive environments such as the laundry room or swimming pool.
Ɣ Any filled with oil,
sulfurated gas or fumes in the air.
Ɣ If placed under 250cm, the cooling
effect of the air conditioner cannot
be fully utilized.

Ɣ Using wire strippers, remove the rubber insulation from both ends of the signal
cable in the lineet to reveal approx. 6 inches (15cm) of wiring.
Ɣ Using a crimp tool, crimp U-Type lugs (not included) on both ends of the wires.
Ɣ Feed the power connection wire from the rear right of the unit though the cable
cross hole and pull it through from the front of the unit.

Ɣ After ensuring that each connection is secure, tightly screw down the cable clamp.
Ɣ Snap the wiring cover back into place and shut the front panel.
NOTE: Make sure the connection is following the instruction.

7. Extend the pipe by unwinding it
Ɣ Extending the pipes should be clung to the wall, bent slowly. The minimum
radius of bending the pipe should not exceed 4 in (10 cm).
Ɣ If the pipe is repeatedly bent or extended, it will become hard and difficult to
manipulate. Avoid bending or extending the pipe for more than 3 times.
Ɣ Make sure the pipe connector is protected from dirt and debris when the pipe
passes through the wall. Covering the connections with tape could do the trick.

b. Remove burrs
Burrs can affect the air-tight seal of refrigerant piping connection. They must be
completely removed.
Ɣ Hold the pipe at a downward angle to prevent burrs from falling into the pipe.
Ɣ Using a reamer or deburring tool, remove all burrs from the cut section of the pipe.

c. Flare pipe ends
Ɣ After removing burrs from the cut pipe, seal the ends with tape to prevent foreign
materials from entering the pipe.
Ɣ Sheath the pipe with insulating material.
Ɣ Place flare nuts on both ends of the pipe. Make sure they are facing in the right
direction, because you can’t put them on or change their direction after flaring.
