1. Precautions
1-1 Installing the air conditioner
● 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 8.2ft(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.
● MH050FXCA2A
- MH052FNCA, MH052FECA and NJ052MHXCA indoor unit cannot be connected to the MH050FXCA2A outdoor unit.
1-2 Power supply and circuit breaker
● If the power cord of the air conditioner is damaged, it must be replaced by the manufacturer 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 >0.12inch(3mm).
● Do not extend an electric cord to the air conditioner.
● The air conditioner must be plugged in after you complete the installation.
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 23ft(7m) from the indoor unit. (If applicable)

Samsung Electronics1-2
1-5 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.
● When installing, make sure there is no leakage. When recovering the refrigerant, ground the compressor first before removing
the connection pipe. If the refrigerant pipe is not properly connected and the compressor works with the service valve open, the
pipe inhales the air and it makes the pressure inside of the refrigerant cycle abnormally high. It may cause explosion and injury.
● Pump Down Procedure (When removing the product)
- Turn on the air conditioner and select Cool mode to run the compressor for 3 minutes.
- Release the valve caps on High and Low pressure side.
- Use L wrench to close the valve on the high pressure side.
- Approximately 2 minutes after, close the valve on the low pressure side.
- Stop operation of the air conditioner.
- Disconnect the pipes.
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.

2. Product Specifications
2-1 The Feature of Product
■Multi Inverter(Free Joint Multi) Series delivers comfort to 2~4 rooms with a Single Outdoor Unit.
■Inverter for High Efficiency Operation.
Thanks to inverter control, efficiency of operation of the outdoor unit is enhanced depending on the number of indoor units
operated and the temperature setting.
When only one indoor unit is used, power is saved, resulting in a smaller electricity bill. When all indoor units are used,
high-power operation achieves comfort quickly in all rooms.
■Installation of indoor units on different floors is possible.
■Convenient Installation
Auto addressing option : Automated checking of pipe connection.(Refer to the installation manual for detail)
■Space saving & Environmental Friendly
• Compact & light outdoor unit
• Slim and quiet indoor units
• Pipe size reduction
• Ozone friendly Refrigerant(R410A)
• Lead Free controller.
■Reliability
• Installation possibilities(Length/Height)
• Convenient installation(485 non polarity/auto-addressing)
• Intelligent control/network
• Easy checking system condition by 7-segment
■Smart & Low Noise outdoor units in any condition
• TBR/Sine-Wave Controller/Noise Reduction Control/Dual Felt etc.
• Felt Structure : New felt has selected to reduce the noise coming out of the compressor.
Double layered felt structure absorbs noise by two times and felt is also covering top of the compressor to
reduce the noise even more.
