Commissioning Procedure
Prerequisites
Check that the smart cooling product is properly powered on.
Before starting the compressor after power-on, ensure that the electric heating belt of the crankcase has been preheated for more than 12 hours.
Context
High-quality refrigerant R410A is recommended.
Wear antifreeze gloves when performing refrigerant related operations.
The following are the tools used for commissioning and refrigerant charging:
- Charging tools: pressure gauge (measuring range ≥ 4.0 MPa), rubber hose (withstand pressure ≥ 4.5 MPa), vacuum pump
- Measurement tool: electronic balance
- Protective tools: insulation gloves, antifreeze gloves, and insulation shoes.
- Other tools: flashlight
To learn the mapping between the saturation pressure and the saturation temperature of the R410A refrigerant, see Table 5-2.

Users include admin (preset password: Changeme) and operator (preset password: Changeme). To enter the diagnostic mode, log in as user admin.
Procedure
- Log in to the ECC800-Pro WebUI as user admin. Choose . The page for commissioning smart cooling products is displayed.
If no manual operation is performed within 25 seconds after you click On, the equipment will automatically run according to the preset logic, and the compressor and indoor and outdoor fans will also run according to environment requirements.
- Choose , set Power on/off to ON, and click Submit.
