type MSH-MStar in a single pipe connection piece (thread M60x1,5)
The multi-jet flow sensor type MSH-VStar has an external thread M60x1,5 connection as described in EN 14154
(M60) and must be installed without an adapter in a single pipe connection piece compatible to EN 14154 (M60).
These pipe connections have no metrological influence on the measurement accuracy.
Important
Before installing the flow meter check if the connection piece has the identification EN14154 (M60). If not, the
label provided with the meter must be applied clearly to the connection piece.
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-AStar in a single pipe connection piece (EAT M77x1,5)
The multi-jet flow sensor type MSH-AStar has an external thread M77x1,5 connection as described in EN 14154
(A1) and must be installed without an adapter in a single pipe connection piece (EAT) compatible to EN 14154
(A1). These pipe connections have no metrological influence on the measurement accuracy.

-
If a plastic adapter was mounted together with the old meter, it is to remove, too.
-
Check sealing surfaces and threads for imperfections or dirt. If necessary, deburr or clean with a suitable
cleaning liquid.
-
Lubricate the external thread (M77x1,5) of the flow sensor and the O-ring (66,35x2,62) with a thin layer of
food safe silicon grease.
-
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.
Attention
When installing, ensure correct positioning regarding the flow by paying attention to the directional arrows on
the outer surface of the EAT and on the bottom of the plastic adapter.
