Installation Manual: Samsung Aj068txj3kg Eu
The Samsung AJ068TXJ3KG/EU is a high-efficiency multi-split outdoor unit (FJM) designed to connect up to three indoor units. Proper installation is critical to maintain its 7.8 SEER rating and ensure the longevity of its R32 refrigerant system.
Detailed documentation can be downloaded directly from the Official Samsung Support UK or viewed on platforms like ManualsLib. Core Installation Steps
The installation manual outlines a 16-step procedure to ensure safety and performance:
Site Selection: Choose a flat, stable surface that can bear the unit’s 57.5kg weight. Ensure the location is well-ventilated, away from direct sunlight, and does not obstruct thoroughfares.
Mechanical Fixing: Secure the outdoor unit in place to prevent vibration and noise. samsung aj068txj3kg eu installation manual
Electrical Connections: Connect power cables (single-phase, 20A fuse rating) and communication cables. Use the 7-segment display on the main PCB to monitor settings and potential errors.
Refrigerant Piping: Connect refrigerant pipes (Liquid: 6.35mm, Gas: 9.52mm). The system supports a maximum pipe length of 25m and a height difference of 15m.
Leak Testing & Vacuuming: Perform a gas leak test and remove air from the circuit before charging with R32 refrigerant.
Auto-Addressing: Utilize the FJM system’s auto-addressing feature, which automatically identifies and assigns addresses to connected indoor units with a single touch. Technical Specifications Cooling Capacity Heating Capacity Refrigerant Type R32 (2.0 kg pre-charge) Dimensions (WxHxD) 880 x 798 x 310 mm Max Indoor Units Up to 3 units Operating Temp (Cooling) -10°C to 46°C Special Environmental Considerations End of manual content.
For installations near the coast (within 500m of the seashore), Samsung requires special anti-corrosion treatments. Installers should apply corrosion inhibitors like Samsung’s R-Pro at least once a year and may need to construct a protection wall to block sea breezes. Air conditioner - Installation manual
Please note: 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.
4. Electrical Installation Essentials
- Isolation and protection: Dedicated circuit with proper overcurrent protection (breaker/fuse) and residual current device (RCD) where required; lock-off and isolate before work.
- Earthing/grounding: A reliable earth connection consistent with local code; verify continuity and bonding.
- Supply rating and cable sizing: Follow manual’s specified voltage, phase (single/three), and current rating; size conductors for continuous load and voltage drop.
- Control wiring: Low-voltage controls must be segregated or screened as recommended; route away from power cables to minimize interference.
- Commissioning checks: Verify correct voltage, phasing (if three-phase), rotation, and that all protective devices are in place and labelled.

AJ068TXJ3KG/EU.
Important Note: The code AJ068TXJ3KG/EU typically refers specifically to the Outdoor Unit (Heat Exchanger) of a Samsung Free Joint Multi (FJM) or a specific split system setup. This guide focuses on installing the outdoor unit and connecting it to compatible indoor units, as the outdoor unit is the heart of the system installation.
Electrical connection
- Turn off mains. Connect power cable to the unit terminal block using correct conductor size and ferrules.
- Grounding: ensure protective earth connected to the indoor unit earth terminal.
- Communication/remote: connect control wires between indoor and outdoor units (polarity as specified). Tie control cable away from high-voltage lines.
- Install circuit breaker and any required surge protection or isolator per local electrical code.
