Precautions

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.

1-5 Precautions for the Pump Down

• The pipes should have no leaks during installation, and the compressor must be stopped before removing
connecting pipes for pump down work. Operating the compressor while 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.
1-6 Others
• 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.).
