  • RECOMMENDED INSTALLATION FOR HEATING SYSTEM OR CHILLED WATER APPLICATIONS

Precautions before/after commissioing
1. Do not open the expansion valve installed in the equipment pipe connection when filling the pipe before commissiong
2. Make sure to check the sealing condtions of the equipment and piping (leakage and abnormal condition) after filling the pipes before commissioning.
3. Make sure to check the filling condition and power supply of the piping system before requesting commissioning.
4. For smooth commissioning, circulate the piping system for at least one week before the commissioning request to remove any residual air in the pipes.
5. Initial Start-up and commissioining should be carried out under the supervision of the construction company, customer, and supplier.
6. Do not change the set values after commissioning
