Common problems
Unit not cooling or heating effectively
Ensure the operating temperature is within the range of -15°C to +46°C and that the pipe run does not exceed the 100m maximum limit.
Difficulty controlling multiple indoor units
An optional central controller is required to manage individual or connected units and schedule operations automatically.
Before use
- Verify that the power supply is 220-240V, 50Hz, Single phase.
- Ensure the installation location can accommodate the unit dimensions (965 x 950 x 370 mm).
- Confirm that the total number of connected indoor units does not exceed 5.
- Check that the total pipe run length is within the 100m limit.
- Ensure the unit is installed in an area that supports the operating temperature range of -15°C to +46°C.
