Installation and Start-Up

Preparation of the Equipment

The retractable housings are mounted and fixed on a vessel (reactor, tank, pipe, etc.) either by
means, a flange connection, or via a NPT external thread.
Attention: Attachment of the flange connection or threaded bushing is the responsibility of the
customer.
In order to guarantee correct function of the retractable housings, please pay attention to the
following installation instructions:
admissible installation
• The retractable housing can be mounted vertically or in an inclined position.
Caution! In the case of inclined mounting, the angle of the housing must be equal to or greater
than 15° above the horizonta;
• The retractable housing is to be mounted in such a position that there is always enough clear-
ance available for its correct functioning (correct "Measuring" position in the sample medium)
as well as for maintenance work (checks, fitting and removal of the electrodes / sensors). The
relative dimensions can be seen on the drawings in the relative Appendix to this Instruction
Manual, or in the specifications;
• Mounting of the retractable housing in exposed positions should be avoided. If this is not
possible, relative measures to protect against damage or interference must be taken.

Fitting and Installation Work

Caution! In all installation work described below, ensure that the equipment in which the housing
is to be installed is in a non-hazardous condition (depressurized, empty, rinsed, vented, etc.).

Fitting the Housing

Caution! Never place or support the housing on the front end of the centering spigot or immer-
sion tube (risk of damage). Ensure that the housing is fitted to the correct, prescribed socket or
flange as directed (see Section 4.2.1.1).
