 SYSTEM TRIAL OPERATION 

This chapter introduces the system trial operation, including the preparation work of the mechanical, water 

system, and electrical parts before start up. 

4.1 PRECAUTIONS BEFORE TRIAL OPERATION 

 Trial operation can only be performed after electrical safety inspection. 

● Do not block the air inlet and outlet. Otherwise, the performance of the unit may be degraded or the protection 
device may be activated and fail to operate. 
● Make sure that all valves are open, flushing and draining the water system pipes, and confirm that the water 
cleanliness meets the requirements. 
● Fill the water system and empty it to ensure that there is no air in the water system. 
● Never perform forced operation. (The protection device does not work, which may cause damage to the unit 
and lose efficacy!). 
● Whether the system is fully warmed up (more than 12 hours). 

4.2 INSPECTION ITEMS AFTER INSTALLATION   

According to this manual, check the installation work by referring to the following table.
