No more than 50 meters of copper piping can stretch from the heart [3].
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
Check that the condensate water flows freely from each indoor unit.
are the communication bus lines. Use a minimum of 0.75 mm² up to 1.5 mm² shielded or unshielded cable depending on local regulations (Samsung recommends a continuous, splice-free wire harness).
The longevity of the AJ068TXJ3KG/EU depends heavily on proper site selection. The location must support the operating weight of the unit and minimize environmental wear. samsung aj068txj3kg eu installation manual
Ensure all piping is thoroughly insulated to prevent sweating and efficiency loss.

Cable specification: Minimum 2.5 mm² 3-core outdoor-rated cable. Communication Wiring (Indoor to Outdoor)
What is the for your specific layout? Share public link No more than 50 meters of copper piping
Calculate the total length of the liquid line by adding the lengths of all individual channels together.
If within 500m of the coast, construct a concrete wall (1.5x unit size) to block sea breeze and apply anti-corrosion treatment (Samsung Code: MOK-220SA). 2. Fixing the Outdoor Unit
Detailed documentation can be downloaded directly from the Official Samsung Support UK or viewed on platforms like ManualsLib .
Isolate the pump and perform a vacuum decay test for 10–15 minutes. If the micron levels rise rapidly and stabilize high, moisture is present. If they rise indefinitely, a leak remains. Refrigerant Adjustments Ample clearance is required: at least 300mm of
The is a multi-split outdoor unit (Free Joint Multi - FJM) designed for residential and small commercial use. It is a versatile system that can connect to up to three indoor units , providing independent climate control for different rooms. Key Technical Specifications Cooling Capacity: Nominal 6.8 kW (24,000 BTU). Heating Capacity: Nominal 8.0 kW.
Fully open both the liquid and gas service valves using an Allen key to release the complete refrigerant charge into the system loop. Step 7: Commissioning and Test Run
Never skip or rush these steps. Moisture or air remaining in an R32 system will corrupt the polyolester (POE) oil, leading to catastrophic compressor failure. Pressure Testing Connect a cylinder of dry nitrogen to the service ports. Pressurize the system to .
This is a generalized expert interpretation of Samsung’s HVAC installation protocols for EU-market cassette-type systems. You must refer to the physical installation manual provided with your unit for torque specifications, refrigerant calculations, and electrical diagrams.
