Power-On Preparations
Procedure
- Ensure that all switches in the indoor unit except QF1 and QF2 are turned on, and the circuit breakers for the outdoor unit, low temperature component, and water-cooled module are switched on.
- Check that the refrigerant pipe between the indoor unit and outdoor unit/water-cooled module is correctly connected and the refrigerant is pre-filled. Check that the cooling water pipe is correctly connected to the water-cooled module.
- Check that the power cables of the indoor unit, outdoor unit, and water-cooled module are correctly connected. Check that the communications cable between the indoor unit and outdoor unit/water-cooled module is correctly connected.
- Verify that the input voltage meets the requirement.
Ensure that there is no reverse or open phase for the input power cable of the smart cooling product. Otherwise, the smart cooling product may be damaged beyond repair.
- If teamwork networking is required, verify that the teamwork cable is correctly connected.
- If the cabinet is connected to the temperature and humidity sensor, check that the cable connection and DIP switch settings are correct.
- If a humidifier is configured, check that the upstream water inlet valve of the humidifier is open.
