Series: Likely part of the 360 Cassette or Slim Duct series (68,000 BTU/h class – commercial light commercial). Market: EU (European Union) – Compliant with F-Gas regulations, CE marking, and ErP directives. Refrigerant: Typically R410A (check unit label; requires R32 handling protocols if newer revision).

Pre-Installation Requirements Before unpacking the unit, verify the following:

Tools: Manifold gauge set (for R410A or R32), vacuum pump (capable of 500 microns), leak detector, torque wrench (10–60 N·m), pipe bender, flaring tool, and an EU-compliant multimeter. Safety: Isolate power supply upstream. Wear gloves, goggles, and refrigerant safety gear. Clearances: Refer to the manual’s dimensional drawing. For cassette units, ensure ceiling plenum space ≥ 300mm below structural slab. The Samsung AJ068TXJ3KG/EU is a high-performance Free Joint

Step 1 – Indoor Unit Mounting (Cassette Assumption)

Ceiling Opening: Cut an opening strictly per the supplied paper template (typically 840x840mm for 6–8HP cassettes). Suspension Bolts: Use M10–M12 threaded rods (field supplied). Adjust height so the unit’s drain pan slopes 1–2° toward the condensate pump outlet. Drain line: Connect the VP25 (25mm OD) drain hose. Must run downhill (1/100 gradient) and be insulated against condensation. Do not connect to sewage pipes without a trap.

Step 2 – Refrigerant Piping The AJ068TXJ3KG/EU uses two refrigerant lines: | Pipe | Size (Typical) | Insulation | | :--- | :--- | :--- | | Liquid | 3/8" (9.52mm) | Minimal (≥ 9mm thick) | | Gas | 5/8" (15.88mm) or 3/4" | Heavy (≥ 13mm thick) | Critical steps: Dimensions : Weight : 57

Braze with nitrogen purge (0.5 kg/cm² flow) to prevent oxidation. Flare connections? Check manual – over 56kW models often require brazed joints for gas line. Pressure test: 40 bar (R410A) for 24 hours, no drop. Triple vacuum evacuation: Pull down to 500 microns, break with nitrogen, repeat, then final to 200 microns.

Step 3 – Electrical Wiring (EU 400V 3N~ 50Hz) This unit requires a 3-phase 400V supply (L1, L2, L3, N, PE).
