RXQ10BYM

🔧 1. Preparation before installation

✅ Required tools and equipment:

• Pressure gauge, clamp meter

• Vacuum pump, copper pipe welding machine

• Screw-tightening tools, torque wrench, adjustable wrench

• Copper pipe meeting specifications (at least Type L)

• Compliant electrical wiring (power cable, control cable)

• Support base or mounting frame (if installing on a roof)

✅ Check that the installation location is suitable:

• A level, sturdy surface that can support at least 300kg (the unit weighs 210kg)

• Clearance requirements:

  • At least 300mm at the sides

  • At least 1,000mm at the front

  • Avoid direct sunlight and locations exposed to strong winds

🧱 2. Securing the outdoor unit

✅ Secure installation:

• Place the outdoor unit on a mounting frame or concrete base with anti-vibration rubber pads.

• Secure it firmly using expansion bolts or dedicated screws.

• Ensure the unit is perfectly level to prevent vibration and compressor damage.

🌀 3. Connecting the copper pipes

✅ Copper pipe requirements:

• Use the sizes specified by Daikin (refer to the technical manual for model RXQ10BYM)

• Braze with nitrogen to prevent pipe oxidation

• Insulate all refrigerant pipes (liquid and gas pipes)

✅ Pipe length and height difference:

• Maximum total pipe length: approximately 165m (follow the technical catalogue)

• Maximum height difference: 50m

• Install an oil separator if the height difference exceeds 40m

⚡ 4. Electrical connection

✅ Power supply:

• 3-phase 380V - 50Hz power

• Adequately rated power cable (minimum 4-6 mm²), with a grounding wire

• A separate circuit breaker or CB for each outdoor unit

✅ Connect according to the wiring diagram:

• Follow the manufacturer's wiring diagram

• Use dedicated, shielded control cable

💨 5. Evacuation and refrigerant charging

✅ Evacuate the entire system:

• Connect a gauge and vacuum pump to the service valve

• Evacuate for at least 30 minutes or until the pressure is < -760mmHg

• Check for leaks using soapy water spray or a refrigerant leak detector

✅ Charging with R410a refrigerant (if additional charge is required):

• Calculate the refrigerant quantity based on the actual pipe length

• Use the correct R410a refrigerant, charge in liquid form, do not charge in vapor form

• Weigh the refrigerant using an electronic scale

🧪 6. Test run and inspection

• Turn on the power CB and check that the voltage is stable

• Start the system using the central controller

• Check the current, refrigerant pressure, noise and vibration

• Ensure that no errors are displayed and that the unit operates stably

📋 7. Handover and operating instructions

• Provide the customer with technical guidance on operation and basic maintenance

• Record the installation specifications: pipe length, refrigerant charge, electrical specifications

• Provide the warranty certificate, installation log and technical documents

⚠️ Important notes

• Installation must be carried out by a Daikin-certified or authorized technical contractor

• Installation errors may result in loss of warranty, reduced performance or equipment damage
