Proper installation of the LG ARWM120LAS5 VRV outdoor unit not only ensures operating performance but also extends the product's service life. The detailed installation procedure is provided below:

1. Preparation Before Installation

Inspect the product: Ensure the product is intact and has not been damaged during transportation.
Select an installation location:
- Ensure there is sufficient space for installation (based on the unit dimensions: 772 x 1,120 x 547 mm).
- Choose a cool, well-ventilated location, away from direct sunlight and areas with high humidity.
- Ensure the supporting surface is level and solid to prevent vibration during operation.
Required tools: Hand tool kit, welding equipment, copper piping, water piping, insulation materials, and a pressure gauge.

2. Installing the Connection Systems

a. Connecting the refrigerant piping

Use copper piping of the appropriate sizes: D12.7/D28.58.
Protect the piping with insulation to prevent heat loss and condensation.
Ensure all joints are sealed to prevent leaks.

b. Connecting the water piping

Select water piping of size 40A in accordance with the technical requirements.
Connect to the heat exchange system, ensuring a water flow rate of 115 LPM.

c. Connecting the electrical system

Use a 3-phase, 380V, 50Hz power supply.
Ensure the electrical wiring meets the required current-carrying capacity standards.
Correctly connect the terminals (Phase, Neutral, Earth) according to the manufacturer's instructions.

3. Positioning and Securing the Unit

Place the unit on a sturdy base, ensuring it does not tilt or vibrate.
Use securing bolts to minimise noise and vibration during operation.

4. Inspection and Completion

a. Checking pressure and leaks

Use a pressure gauge to check the refrigerant piping system.
Ensure there are no leaks at the joints.

b. Checking the water flow rate

Ensure the water piping system operates smoothly, with a flow rate of 115 LPM.

c. Test run

Turn on the power and check the operation of the outdoor unit.
Measure the noise level (60 dB(A) for cooling and 63 dB(A) for heating) to ensure the unit operates within the specified standards.

5. Installation Notes

Electrical safety: Disconnect the power before installation or maintenance.
Installation clearance: Maintain the minimum clearance between the outdoor unit and surrounding objects to ensure unobstructed airflow.
