flush the pipe system thoroughly. Then close the
shut-off valves, remove the fitting piece, clean the
sealing surfaces and install the flow sensor using
new gaskets. Take care to not reduce the pipe
diameter by bad positioning of the gaskets,
particularly if flanged versions are installed.
5.2 Installation of the temperature sensors
PolluTherm operates with separately approved
and paired temperature sensors type Pt 500. The
applicable type is specified on the front of the
integrator.
We recommend the use of the MID starter kit
consisting of special ball valves with temperature
sensor entries M 10 x 1 with integrated union nuts
and one spool piece (see manual MH 1131 INT).
This starter kit is compatible with temperature
sensor types L = 45 mm / D = 5,2 and DS 27,5. It
is available up to R1 ½ " (DN 40).
When using Sensus temperature sensors, length
100 and 150mm the sensitive zone is ca. 10 to 15
mm measured from the temperature sensor's tip
and has to be positioned as close as possible to
the middle of the pipe diameter. Refer to the
following guide for installing such temperature
sensors:
Nominal sizes < DN 50*: Install the temperature
sensors in an angle of 45° towards the flow
direction (see figure 4).
Nominal sizes > DN 100*: Install the temperature
sensors vertically to the flow direction (see figure
5).
For DN 65 and DN 80 both installation positions
are valid
For larger nominal sizes (e.g. DN 150) the
immersion sleeve has to be immersed at least as
deep as 50 mm into the pipe.

* < DN 50 installation in a pipe elbow is also possible

5.3 Mounting of the integrator

Fasten the enclosed C-rail with two screws in a
horizontal position at the chosen place. Attach the
housing to the C-rail and lift the red snap hook
using a flat slot screw driver.
Press the body onto the C-rail and release the
snap hook.
For removal lift the red snap hook with a flat slot
screw driver and take the housing off.

6. Connection of the sub-units

To open the housing press the two locking caps at
the two lower angles of the housing lid and turn
the lid upwards.
