* Depending on the specifications, the product may or may not feature an overflow outlet for 

the exhaust pipe. 

 

 

Shutdown 

1.  Stop the equipment, making sure that there is no flow of waste steam. 

2.  Close the cold water inlet valve (A) and the hot water outlet valve (B) to stop the 

inflow of cold water. At this point, make sure to close the valve slowly not rapidly. 
(If the valve is closed rapidly, water hammer will occur, resulting in impacts to the 
SR and the surrounding piping.) 

3.  When the SR is to be shutdown for long periods of time, discharge all condensate 

by opening the blow valve (C) at the bottom of the body.
