4. The sensor can be installed by one of three procedures:
In all cases a female G1/2 or Rc1/2 thread is required
a. in an existing socket with a length of max. 25 mm
b. in a T-piece (Fig. 3)
c. in a welding sleeve with a length of max. 25 mm
(probe tip must be well within the ow).
CAUTION! Fittings with a reduced bore or collar could narrow the
threaded connection due to radial compression, and this in turn could
block the probe tip in the t, which has now become too narrow, and
cause irreparable damage.
INSTALLATION
To provide protection against corrosion and limescale, cleaning and
ushing of the system followed by chemical addition of inhibitor should be
considered. Major boiler manufacturers recommend that once cleaned,
commercial heating and closed cooling systems should be dosed with
Sentinel X100 Inhibitor. Prior to adding X100, the system should be cleaned
with either X400 High Performance Cleaner or X800 Fast Acting Cleaner.

1. Screw the threaded connection tight. Use a suitable sealant. (Fig. 3)
CAUTION! Hand-tighten this threaded connection loosely and
then tighten another quarter turn using a wrench. The connection
should not be forced. If tightened with too much force, the threaded
connection could be narrowed due to radial compression, and this,
in turn, could block the probe tip in the t that has now become too
narrow, and cause irreparable damage.
