Maintanance and maintenance-intervals have to be defined by the operator according to
the requirements.
7.1 Cleaning / replacing controller assembly
(refer to Fig. 1 page 4 - Fig. 3 page 7)
- Depressurise unit (isolate feed line, also discharge line if there is back pressure).
- Release and dismantle screw cap (Pos. 6).
- Unscrew bimetallic controller (Pos. 24) and strainer (Pos. 2)
- Clean body (Pos 1), screw cap/cover (Pos. 6), strainer (Pos. 2) and all seal faces.
- Clean bimetallic controller (Pos. 24) and check sealing parts at seat (Pos. 24.1). If the
operator thinks there is unwarranted leakage at the steam trap we recommend checking
the controller setting or replacing the complete bimetallic controller (Pos. 24).

ATTENTION !
- refer to item 10.0 and 11.0 prior to dismantling and repair work!
- refer to item 6.0 before restarting the plant !
Prior to installation, threads and seal faces should be coated with temperature-
stable lubricant (e.g. “OKS Anti-Seize Paste” white/metal-free for PN16-40 or
“Rivolta” lubricant and parting agent silver for PN63 onwards).
