10.3. Check of safety valve(s)
The safety valve(s) needs to be checked once per year. This should be done by a specially trained
service stuff. Other safety checks are necessary so we recommend to make one safety check
together with the yearly maintenance check by a trained service engineer. While testing the function
of the safety valve hot steam is leaving the safety valve
The safety valve is checked by turning the knurled screw at the upper end of the safety valve until the
valve opens. The valve is then closed again. To blow off the valve, there must be an overpressure in
the chamber, so a program must be started. The test is carried out in the heating phase of the
program, the program is then canceled. A special test program for starting the safety valve is
available for authorized customer service technicians. Please ask the manufacturer who has been
authorized in your area to properly maintain the device.
Attention please! While steam is leaving the safety valve the
valve is getting very hot in a very short time! Make sure that
your skin is not coming in contact with the steam! Contact
with the steam can burn your skin!
If the valve is not closing completely after testing it needs to
be changed! If there are doubts about the regular
functionality of the tested valve it needs to be changed!
