Precautions
Samsung Electronics 1-1
• If the power cord of the air conditioner is damaged, it must be replaced by
themanufacturer or a qualified person in order to avoid a hazard.
• The air conditioner must be plugged into an independent circuit if
applicable or connect the power cable to the auxiliary circuit breaker.
An all pole disconnection from the power supply must be incorporated in
the fixed wiring with a contact opening of >3mm.
• Do not extend an electric cord to the air conditioner.
• The air conditioner must be plugged in afteryou complete the
installation.
• Users should not install the air conditioner by themselves.
Ask the dealer or authorized company to install the air conditioner
except the window-type air conditioner in U.S.A and Canada.
• If you don’t install the air conditioner properly, it may cause a fire,
a water leakage or an electric shock.
• You must install the air conditioner according to the national wiring
regulations and safety regulations.
• Install the indoor unit higher than 2.5m from the floor to avoid
the injury caused by the operation of the fan.
(except the window-type air conditioner)
• The manufacturer is not responsible for any accidents or injury
caused by an incorrect installation.
When installing the built-in type air conditioner, keep all electric cables such as the power cable and the
connection cord in pipes, ducts, or cable channels to protect them from the danger of impact or any other incidents.
• More than 2 indoor units should be installed when you use Free Joint Multi air conditioner.
• AJ020TX**CH outdoor unit
- AR18/24TSF*BWKN, AJ018TNNDCH, AJ018TNLDCH, AJ018TNJDCH indoor units cannot be connected
AJ024TXJ3CH outdoor unit
- AR24TSF*BWKN indoor units cannot be connected
AJ024TXS4CH outdoor unit
- AR24TSF*BWKN, AJ018TNJDCH indoor units cannot be connected
1. Precautions
1-1 Precautions for the Service
su oreg na d
Avoid Dangerous Contact
1-2 Precautions for the Static Electricity and PL
No Tapping and No Extension Cords

Precautions
1-2 Samsung Electronics
1-3 During operation
• Do not repair the air conditioner at your discretion.
It is recommended to contact a service center directly.
• Never spill any kind of liquid on the air conditioner.
If this happens, turn off the air conditioner and contact an authorized
service center.
• Do not insert anything between the airflow blades to prevent damage
of the inner fan and consequent injury.
Keep children away from the air conditioner.
• Do not place any obstacles in front of the air conditioner.
• Do not spray any kind of liquid into the indoor unit. If this happens,
turn off the air conditioner and contact a service center.
• Make sure that the air conditioner is well ventilated at all times:
Do not place a cloth or other materials over it.
• Remove the batteries if you don’t use the remote control for a long time. (If applicable)
• Use the remote control within 7 meters from the indoor unit. (If applicable)
1-4 Disposing of the unit
• Before throwing out the air conditioner, remove the batteries from the remote control.
• When you dispose of the air conditioner, consult your dealer. If pipes are removed incorrectly, refrigerant may
blow out and cause air pollution. When it contacts with your skin, it can cause skin injury.
• The package of the air conditioner should be recycled or disposed of properly for environmental reasons.
No children Nearby
1-5 Precautions for the Pump Down
1-6 Others
• The pipes should have no leaks during installation, and the compressor must be stopped before removing
connecting pipes for pump down work. Operating the compressorwhile the service valve is open and coolant
pipe is not properly connected may cause explosion or injury due to abnormal high pressure created inside
the coolant cycle as the air can be absorbed through the pipe.
• Pump Down work procedure (When uninstalling the product)
- Turn on the air conditioner, select cooling operation, and run the compressor for more than 5 minutes.
- Release the high pressure and low pressure valve caps.
- Close the high pressure valve completely using an L-wrench.
- After about 2 minutes, close the low pressure valve completely.
• Never store or load the air conditioner upside down or sideways to prevent the damage to the compressor.
• Young children or infirm persons should be always supervised when they use the air conditioner.
• Max current is measured according to IEC standard for safety.
• Current is measured according to ISO standard for energy efficiency.
• For servicing the units containing flammable refrigerants, safety checks are required to minimise the risk of
ignition.
•
Servicing shall be performed following the controlled procedure to minimize the risk of flammable refrigerant
or gases.
• For servicing with handling the R-32 refrigerant, use the special tools for the R32 refrigerant
(manifold gauge, vacuu pump, charging hose, etc.).
