4 Installation and Operating Instructions TTP x00
1 Installation
1.1 Mechanical installation
• Use only the recommended sleeves or adapters. If other systems are used, no guarantee can
be given for proper functioning or leak-tightness.
• Do not use Teflon or paper gaskets for the hygienic process connections featuring a conical
seal.
• The tightening torque for the sleeve should be between 10 and 20 Nm.
1.2 Process connections
The hygienic weldable process sleeves are easy to weld into tanks and pipes. The marking points
to the centre of the future position of the cable gland or M12 connector. This form of assembly
allows installation in conformity with standards of hygiene (to EHEDG, FDA).
Various hygienic adapter sleeves (see Accessories) are available for fitting to other process
connections.
• Process connection G1/2“h is the hygienic standard connection with conical seal.
• For installation in small-diameter pipelines it is recommended to use the hygienic M12 system
(from DN 15).
• When using a sliding sleeve, please use the threadless variant. The clamp cone forms a
hygienic seal with the protective tube.
• A standard G1/2“ connection is available for applications with no hygiene requirements (e.g.
cooling water).
