R32 (Pre-charged for specific total piping lengths; check factory label). Maximum Indoor Units: Up to 3 ports. Nominal Cooling Capacity: 6.8 kW. Electrical Supply: 220–240V, single-phase, 50Hz.
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).
Position the unit to avoid noise or hot air disturbing neighbors.
Choose a rigid, level surface—such as a concrete pad or heavy-duty wall brackets—capable of supporting more than the unit's operating weight without transmitting vibration. samsung aj068txj3kg eu installation manual
The manual details an essential procedure for configuring each indoor unit's address and operational options before finalizing the installation. These settings are managed through the wireless remote controller. The default setting for an indoor unit is 02000-100000-200000-300000 , but this can be changed to suit the system plan, allowing for individual or grouped control of the indoor units.
The manual provided clear instructions on the installation process, including:
Incorrect wiring is the leading cause of main PCB failures in Samsung multi-split systems. Ensure all power supplies are isolated before opening the electrical cover. R32 (Pre-charged for specific total piping lengths; check
Samsung multi-split units feature an automated configuration utility that detects connected indoor units and checks for cross-wiring.
Hold the pipe downward while using a reamer to remove burrs. This prevents copper shavings from entering the refrigeration circuit.
Check that the condensate water flows freely from each indoor unit. Electrical Supply: 220–240V, single-phase, 50Hz
At least 600 mm for maintenance and wiring access.
Isolate the vacuum pump and monitor the micron gauge for 10 minutes. If the pressure rises rapidly or stalls above 500 microns, moisture or a micro-leak is present. Step 6: Additional Refrigerant Charging
The AJ068TXJ3KG/EU must map its electronic expansion valves (EEVs) to the corresponding indoor units. This is done via the outdoor unit’s main PCB display.
Strictly observe the physical limits of the multi-split layout: 50 meters Maximum Individual Room Pipe Length: 25 meters
