type MSH-SStar in a single pipe connection piece (EAS)
The multi-jet flow sensor type MSH-SStar has a 2“ connection as described in EN 14154 (IST) and must be installed
without an adapter in a single pipe connection piece (EAS) compatible to EN 14154 (IST). These EASs are pipe
connections which have no metrological influence on the measurement accuracy.
Important
Before installing the flow meter check if the EAS has the identification EN14154 (IST). If not, the label provided
with the meter must be applied clearly to the EAS.
Mounting
-
Flush the pipes according to the generally acknowledged rules of technology. Then close all the shut-off
valves. Open the nearest draining valve for pressure release.
-
Drain the closed-off pipe section.
-
Take into account the direction of flow (connection piece)!
-
Remove the overflow flange or the old heat meter from the connection piece using a wrench.
-
Remove all old gaskets. Check sealing surfaces and threads for imperfections or dirt. If necessary, deburr
or clean with a suitable cleaning liquid.
-
Place the new profile gasket into the connection piece with the flat surface facing
up.
-
Lubricate the external thread of the flow sensor with a thin layer of food safe silicon
grease.
-
Check that the O-ring on the outlet of the flow sensor is in the correct position.
-
Screw in the heat meter tightly by hand and then tighten additionally with a suitable
wrench to the mechanical end stop (metal-to-metal).
-
Detach the calculator and mount it, or rotate it to the best position for read-out.

type MSH-VStar in a single pipe connection piece (ASS)
The multi-jet flow sensor type MSH-VStar has an external thread M62x2 connection as described in EN 14154
(TE1) and must be installed without an adapter in a single pipe connection piece (ASS) compatible to EN 14154
(TE1). These ASSs are pipe connections which have no metrological influence on the measurement accuracy.
Important
Before installing the flow meter check if the ASS has the identification EN14154 (TE1). If not, the label provided
with the meter must be applied clearly to the ASS.
