✅ 1. Preparation before installation

📌 Check the installation position

• Location to ensure ventilated, It's not windblown and it's blowing out, maybe easy to maintain.

• Do not install near steam, corrosive gas, or a fire-prone area.

• Make sure the surface is flat and load - bearing ( ≥ 350kg).

• Minimum distance:

  • In front of outdoor unit: ≥ 1,000mm

  • Rear, side: ≥ 300mm

  • Top: ≥ 500mm

  • Between outdoor unit: ≥ 100mm

  • Height difference between outdoor unit and indoor unit: in terms of Daikin limit (typically ≤ 50 m)

. 2. Construction of base and frame outdoor unit

🧱 Concrete base

• Solesize: longer and wider than the base outdoor unit from 100 – 200mm.

• Pour concrete M200, at least thick 150mm.

• Insert the M12 or M14 wait bolts to fix outdoor unit.

🪵 Steel frame (in case of hanging or roof)

• Use ≥ 5mm - bearing box/inox steel.

• Fixed solder, rust - resistant 2 coating and top coat.

• Check your nivo balance after you finish.

✅ 3. Installation and immobilization outdoor unit RXQ18BYM

• Use a forklift or palang to lower the outdoor unit up into position.

• Line the base with vibration - resistant rubber.

• Squeeze the bolt firmly, but not so tight that it cracks the case.

• Check the equilibrium outdoor unit with nivo.

✅ 4. Gas connection

🔧 Copper pipe technical requirements

• Use copper tubing soft cast whole - plant (coil) meets JIS H3300 Mortality Type H standard.

• The pipe diameter should be the manufacturer's design for the model RXQ18BYM (e.g., Ø 28.58mm or Ø 34.9mm depending on power).

🔧 Duct wiring technique

• Use a flare and wrench to apply the force to the right torque Daikin.

• Vacuum the entire system after the connection.

• Check for leaks with a spray bottle or pressure gauge.

• Sealable insulation and tape 100%.

⚡ Source Parameters

• Power source: 3 phase ~ 380 V – 50 Hz

• Capacity: 13.8kW

• Rated current: refer to technical documentation Daikin

⚡ Outdoor Electrical Panel Installation

• Electrical wires: negative chicken intubation/PVC pipe.

• Use copper wire with a minimum load 10mm²).

• Attach separate CBs to each outdoor unit.

• Secure grounding <10 Ω (separate grounding if necessary).

✅ 6. Control signal connection (if any)

• Use the control wire attached to indoor unit, the B/C center, or the central control (if applicable).

• Make sure the polarity is correct (S1 – S2 – S3) and do not share the tube with the power source.

* 7. Test and run

• Full check:

  • Gas pressure

  • Power Voltage

  • Match Map Connection

  • No gas leaks or electrical leaks

• Boot the system from the central controller or from indoor unit.

• Monitor the current, noise, vibration, wind temperature after 10 – 15 minutes of operation.

✅ 8. Maintenance and recommendations

• Regular maintenance every 3 – 6 months:

  • Clean the cooling system

  • Gas pressure check

  • Squeeze the electrical connectors

  • Check fan outdoor unit And the capacitor boots

• Do not keep the machine running for more than 24 h/day It's high-throughput.
