7.3 Installation steps

Fittings should only be finally unpacked at the installation site and inspected for damage prior to assembly.
Damaged fittings must not be installed.
It is necessary to ensure that the covers have been removed from all the connection branches before
installation.
The fitting should be inspected to ensure that it is clean. Interior parts must be free of liquid (e.g. condensate): if
necessary, connecting branches should be cleaned before installation with clean compressed air.
The type and dimensions of the line or tank connections must match the fitting to be installed and be flush with
the connecting surfaces of the fitting as well as in a parallel plane to the fitting itself.
If the fitting is marked with an arrow on the housing, the flow in the pipe section must match the marked
direction of flow.
If installed in the opposite direction to the arrow, the fitting will not perform its intended
function.
caution
The fitting mist be installed without any tension. In the case of an already installed system, the geometry of the
pipeline must match the face-to-face length of the fitting.
It is necessary to ensure that even under operating conditions no tension from the pipeline
is transferred to the fitting.
note
A MANKENBERG fitting made of "high grade" or "high grade pure" stainless steel (austenite,
e.g. 1.4404 or 1.4435) does not need any surface protection for normal environmental
atmosphere and for normal weather conditions.
note
External parts of the fitting made of low-alloy or non-alloy materials that are supplied ex-works
with a primer have to be provided with a suitable coating by the customer.
caution:
Never paint over the marking(s) of the fitting (either etched into the body or on nameplate).
A pressure-regulating valve should first be adjusted during the initial start-up by setting the adjusting screw on
the pilot valve to the operating conditions – see section
In addition, the following applies to the pipeline connection:
with flanges:
The sealing surfaces on the body of the fitting are formed in accordance with the
MANKENBERG order confirmation. The accompanying flange seals are generally not
included in the MANKENBERG supply schedule..
note
During installation, centre the fitting by means of the flange screws on the mating flange before the screws are
tightened.
