- Ensure the installation area is spacious enough and can support the unit's weight (at least 3,611 kg during operation).
- The foundation must be level and solid to prevent vibration.
- Ensure adequate clearance around the unit for maintenance and heat dissipation.
Check the power supply specifications:
- Confirm that the 3-phase, 400V, 50Hz power supply meets the unit's requirements.
- Install an electrical grounding system to ensure safety.
Check the included equipment:
- Ensure all accessories are present, including connection pipes, valves, pressure gauges, chilled water and cooling water pumps.
- Check the refrigerant (R1234ze) and water levels in the system.

2. Installing the Chiller Air Conditioner

Connect the piping:
- Evaporator: Connect the water supply pipe (168.3 mm) and the water outlet pipe in the correct flow direction.
- Condenser: Connect the cooling water supply pipe (219.1 mm) and the water outlet pipe.
- Ensure all connections are secure and leak-free.
Install the water pumps:
- Select pumps with suitable flow rates (31.5 l/s for the evaporator, 38.1 l/s for the condenser).
- Install a filter at the inlet to prevent debris from clogging the system.
Connect the power supply:
- Connect the power supply according to the manufacturer's wiring diagram.
- Check the connections, circuit breaker, and grounding system before switching on the power.
Check the system for leaks:
- Perform a pressure test to ensure there are no leaks in the piping system or compressor.

Initial startup:
- Check the entire system, including the power supply, pressure, water flow rate, and refrigerant.
- Switch on the power and start the compressor from the control panel.
Set operating parameters:
- Set the chilled water outlet temperature according to requirements (usually from 7°C – 12°C).
- Check operating parameters such as cooling capacity, current consumption, and pressure.
Monitor during the initial period:
- Observe the indicators on the control panel to ensure the unit is operating stably.
- Listen to the operating sounds to detect any abnormalities.

4. Periodic Maintenance and Inspection

Monthly maintenance:
- Clean the evaporator and condenser to remove scale and dust.
- Check the electrical system and ensure connections are not loose or burnt.
Annual maintenance:
- Check and replenish the refrigerant if necessary.
