Mounting cover
Attention!
Equipment may leak if the gasket is
damaged.
It is therefore essential that you
always insert a new gasket before re-
attaching the cover.
Make sure that the cover is not tilted
or skewed when refitted.
Clean the gasket surfaces of the cover and
body.
Apply heat resistant lubricant to the threads and
bearing faces of the screws.
The lubricant must have the same properties as
OKS
®
217.
Put a new body gasket (3) onto the body (2).
Insert the four hexagon-head cap screws (10)
into the bores of the body.
Refit the cover (8) onto the body such that the
name plate (7) points upwards.
Tighten the hexagon-head cap screws with a
torque of 140 Nm.
If necessary, mount the measuring electrode as
described on page 16.
