Safety Instructions; Requirements For The Installation - Xylem SENSUS MID Bedienungsanleitung

PolluCom E, PolluStat, PolluTherm, PolluWatt Duo II installation manual
For PolluStat, PolluTherm and PolluWatt Duo II with flanged flow sensors the ball valves, sensor pockets and
spool pieces have to be ordered separately.

2. Safety instructions

Important information for prevention of personal and / or property damage:
 The installation requires adequate professional knowledge and should be carried out by specially
trained persons only.
In order to ensure correct installation please use suitable tools!

 Pipelines of heating systems contain hot water and are under pressure (danger of scalding)!
Pipelines of cooling systems are also under pressure!
 Unless shut-off valves have been fitted on either side of the components to be installed and have
been turned off, the heating/cooling system must be completely depressurized prior to
assembly/dismantling of directly installed sensor pockets, ball valves or temperature sensors!
 The permitted operation pressure of PN16 should not be exceeded!
 Close the shut-off valves before installation / disassembly of temperature sensors in ball valves
(usually this position is right-angled to the flow direction; use the correct position anyway)!
 Depending on manufacturing conditions the connection threads may have sharp edges. Therefore
we recommend wearing protective gloves.
3. Installation and operational instructions with examples (see also EN

3.1. Requirements for the installation

The installation equipment is suitable for heating and cooling systems. Therefore the text hereinafter includes
following terms:
Return pipe of heating systems:
Supply pipe of heating systems:
Return pipe of cooling systems:
Supply pipe of cooling systems:
Sensus heating and cooling meters in standard version are installed in the colder line. Sensus heating and
cooling meters for installation in the warmer line are additionally marked with „X", e.g. PolluCom EX.
It is advisable to install a filter in front of the flow sensor or at another suitable point of the heating or cooling
circuit as well as shut-off valves before and after the flow sensor (so that the pipe line doesn't have to be
emptied if the meter has to be exchanged).
