4.2 Installation of

connection piece

The multi-jet flow sensor type MSH-IST has a 2" connection as described in EN ISO 4064-4 / EN 14154-2 (IST;

interface for Ista heat meters) and must be installed without an adapter.

Mounting the flow sensor type MSH-IST in a single pipe connection piece

Flush the pipes professionally, taking care not to damage any system components. 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 (check the 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, debur or

clean with a suitable cleaning

Place the new profile gasket into the connection piece with the flat surface facing

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).

Rotate the calculator to the best position for read-out, or detach it and mount it nearby.

5 Detachable Calculator

We also provide meters with detachable calculators, in order to simplify

mounting in narrow installation spaces. To release the calculator pull it carefully

up off the flow sensor.

For mounting the calculator on the wall, a wall support is latched onto the

adapter of the flow sensor (between calculator and flow sensor). Remove the

calculator. Hold the adapter of the flow sensor and rotate the wall mounting

support anticlockwise until you can release it. Then attach the wall support at the

desired place with the flat surface towards the wall.
