Page 3: Safety Precautions
❇ Generally, system air conditioners should not be relocated after installation. But when it has to be relocated for inevitable reasons, please contact Samsung’s qualified dealers for system air conditioners. • Hazards or unsafe practices that may result in severe personal injury or death. - Page 4 Safety precautions Check the following before installation and service work. Before welding, remove dangerous and inflammable things that may cause an explosion and fire around the work. Before welding, remove the refrigerant from inside the pipe or the product. - If you perform welding while refrigerant is in the pipe, it may increase the pressure of the refrigerant and cause the pipe to burst.
- Page 5 CAUTION SIGNS Do not install the drain pipe directly to the bottom part of the outdoor unit and built a proper drainage so that water drains out smoothly. If not, pipe may freeze or bursts during winter time and cause damage to the product or water leakage.

Page 31: Refrigerant Pipe Installation
Refrigerant pipe installation • When installing, make sure there is no leakage. When collecting the refrigerant, stop the compressor first before removing the connection pipe. If the refrigerant pipe is not properly connected and the compressor works WARNING with the service valve open, the pipe inhales the air and it makes the pressure inside of the refrigerant cycle abnormally high which may lead to explosion and injury. - Page 32 Refrigerant pipe installation Selecting refrigerant pipe First branch joint Increase the main pipe size Install the refrigerant pipe according to main pipe size of each outdoor unit capacity. When the pipe length (including elbow) between an outdoor unit and the farthest indoor unit exceeds 90m, you must increase the size of the pipe (main pipe) by one grade which connects between the outdoor unit to the first branch joint.

Page 98: Setting The Mcu And Pipe Addresses (For Hr Only)
Setting the MCU and Pipe Addresses (for HR Only) You can set the MCU address, the MCU ports to use, and the address for each MCU port connected to each indoor unit. ✴ It is for 2nd-generation MCU only. (MCU-S NEK2N,MCU-S4NEK3N,MCU-S1NEK1N) Setting the MCU address and the MCU ports to use You can set the MCU address and the MCU ports on the MCU PBA. - Page 99 Setting the Pipe Addresses Manually You can use the wired or wireless remote control or the S-NET Pro 2 to set the pipe addresses for each indoor unit. Setting by using the wired or wireless remote control (For how to operate the remote control buttons, see the remote control user manual.) 1.
- Page 100 Setting the MCU and Pipe Addresses (for HR Only) Setting the Pipe Addresses Automatically (Auto pipe pairing operation) You can use the Automatic pipe-address setting operation to automatically set the address of each MCU port that is connected to an indoor unit. If an MCU port is set incorrectly or a pipe between an MCU and an indoor unit is connected incorrectly, that indoor unit is indicated.
- Page 101 ❇ Before running the Auto pipe pairing operation, be sure to close the front cabinet. If this operation is run with the front cabinet open, the product may be damaged and the pipe addresses cannot be correctly recognized. To run the Auto pipe pairing operation, take the following steps: 1.
