Insulate both pipes separately with closed-cell foam (minimum 9mm thick for liquid, 13mm for gas). Wrap insulation past the flare nut. Use vinyl tape to seal seams – no exposed copper.
The Samsung AJ068TXJ3KG/EU installation manual is not a suggestion – it is a binding set of safety and performance requirements. Cutting corners on piping cleanliness, vacuum depth, or electrical phasing will lead to premature compressor failure or voided warranty.
Always download the latest version from Samsung’s official EU portal before starting any work. If you are not an F-Gas certified technician, hire one. Your comfort and safety depend on a correct, manual-compliant installation.

The Samsung AJ068TXJ3KG/EU is a multi-split outdoor unit designed for high-efficiency climate control. Proper installation is critical for performance, safety, and maintaining warranty coverage. This essay outlines the essential stages of the installation process, from site selection to final commissioning. Site Selection and Preparation
The installation begins with choosing an optimal location for the outdoor unit. The site must be strong enough to support the unit’s weight and minimize vibration transfer to the building structure. Ample clearance is required: at least 300mm of open space on the back and sides, and 600mm at the front to ensure unrestricted airflow. The unit should be placed away from direct sunlight, strong winds, and areas where noise might disturb neighbors. Mounting and Piping
The unit must be secured to a level concrete pad or a sturdy wall bracket using anchor bolts. To reduce noise, vibration-proof rubber pads should be placed between the unit’s feet and the mounting surface. Once secured, the refrigerant piping is connected. This model uses R32 refrigerant, requiring high-quality copper tubing and flare connections. Installers must ensure the total piping length and height difference between the outdoor and indoor units do not exceed the limits specified in the technical data sheet to prevent oil return issues and capacity loss. Electrical Connections
Wiring must comply with local electrical codes and the circuit diagram provided on the unit's control cover. A dedicated circuit breaker and a properly sized power cable are mandatory. The communication cable (F1/F2 terminals) connects the outdoor unit to the indoor units; this cable should be shielded to prevent electromagnetic interference. All connections must be tight, and the unit must be securely grounded to prevent electrical shocks. Pressure Testing and Evacuation
Before charging the system, the refrigerant lines must undergo a nitrogen pressure test (typically at 4.15 MPa) for at least 24 hours to detect leaks. After confirming the system is airtight, a vacuum pump is used to evacuate the lines to a minimum of 500 microns. This step is vital to remove moisture and non-condensable gases, which can cause compressor failure or reduced cooling efficiency. Final Commissioning
The final stage involves opening the service valves and performing a test run. The installer should check the operating pressures, current draw, and temperature differentials at the indoor units. Samsung’s digital display on the main PCB will provide error codes or status updates during this phase. Once the system is confirmed to be operating within normal parameters, the installer should brief the user on basic operation and maintenance, such as cleaning filters and keeping the outdoor coil free of debris.

Deep within the sterile, humming halls of the Samsung Engineering archives, there exists a document known only by its cold, alphanumeric designation: AJ068TXJ3KG/EU.
To the uninitiated, it is a mere technical manual for a Multi-Split Outdoor Unit. But to those tasked with its installation, it is a sacred blueprint for taming the very atmosphere. The Awakening: Preparation
The story begins not with a wrench, but with a vision. You stand before the bare bones of a structure, the AJ068TXJ3KG/EU unit resting in its crate like a sleeping titan. Before the first bolt is turned, the manual demands a ritual of space and breath. You must ensure the unit has "breathing room"—specific clearances of at least 300mm on the back and 600mm on the service side—lest it suffocate in its own heat [1, 3]. The Path of the Copper Veins
As the installation progresses, you begin the delicate work of laying the "veins." This unit is a heart that pumps life to three separate zones. The manual dictates a precise geometry:
The Total Length: No more than 50 meters of copper piping can stretch from the heart [3].
The Ascent: A vertical climb of no more than 15 meters between the outdoor unit and its indoor counterparts [3].
Every flare connection is a moment of high tension. One slip, one burr left on the pipe, and the lifeblood (the R32 refrigerant) will leak into the void. You apply the torque wrench with the steady hand of a surgeon, hearing the "click" that signals a perfect seal. The Electric Pulse
Next comes the spark. The AJ068TXJ3KG/EU requires a dedicated 220-240V circuit. You weave the communication cables—the F1 and F2 lines—connecting the brain of the outdoor unit to the sensors inside. In this digital dialogue, there is no room for error; a crossed wire here means a silent system and a "Communication Error" etched in glowing red LEDs [2, 3]. The Final Breath: Vacuum and Charge
The climax of the tale is the Vacuum Drying. You attach the pump, pulling every molecule of moisture and air from the lines until the gauge hits -0.1 MPa. Only then do you release the refrigerant. The valves hiss, the pressure stabilizes, and the AJ068TXJ3KG/EU hums to life for the first time [1, 3].
As the cool air finally begins to flow, the manual is closed. The mechanical beast is tamed, and the silence of a perfectly regulated home is your only reward. AI responses may include mistakes. Learn more
