1. Preinstallation preparation
- Product Testing: Ensure the products are intact and not damaged during the transportation.
- Select Installation Location:
- Make sure there is enough room for the installation (according to machine size: 772 x 1,120 x 547 mm).
- A well - ventilated area, away from direct sunlight and high humidity.
- Make sure the substrate is flat and firm to avoid shaking during operation.
- Tools required: Hand-held tool kits, solders, copper pipes, water pipes, insulation, and pressure gauges.
2 Installation of the Interconnection System
a. Pipeline connection refrigerant
- Use suitable sized copper tubing: D12.7/D28.58.
- Protect the tubing with a heat protectant layer to prevent heat loss and stagnation.
- Make sure the connections are sealed to prevent leaks.
b/Connecting water pipelines
- Select a size pipe 40A in accordance with technical requirements.
- Connected to the heat exchange system, guaranteed water flow at 115 LPM.
c/Connection of power systems
- Use 3 phase, 380 V, 50 Hz power.
- Make sure the wires are rated for load bearing.
- Connect the poles correctly (Part, Medium, Earth) according to manufacturer instructions.
3 Machine Installation and Fixation
- Place the machine on a sturdy support, making sure it doesn't tilt or shake.
- Use a fixed bolt to minimize noise and vibration when the machine is running.
4 Testing and Refinement
a. Pressure and leakage inspection
- Use a pressure gauge to test the refrigerant pipeline system.
- Make sure there are no leaks at the junctions.
b. Water flow checking
- Ensure that the water pipeline system is running smoothly and that the flow rate is at 115 LPM.
c. Test run
- Power on and check the outdoor unit activity.
- Noise measurements (60 dB(A) for cooling and 63 dB(A )for heating) to ensure that the machine is operating in the proper standard.
5. Installation Notes
