It is necessary to check the safety valve each time before putting it into operation. It is checked
by manual moving of the membrane from the seat, turning the make-and-break device button
always in the direction of the arrow. After being turned, the button must click back into a notch.
Proper function of the make-and-break device results in water draining through the safety valve
outlet pipe. In common operation, such a check needs to be implemented at least once a month,
and after each heater shutdown for more than 5 days. Water may be dripping off the drain pipe
of the safety valve; the pipe must be open into the air, pointed down; environment
temperatures must not drop below zero.
Find necessary pressure values in the below. (Table 4)
Heaters must be provided with a discharge valve mounted on the cold service water inlet to the heater
for potential disassembly or repair. When assembling the security equipment, follow the standard.
