Installation for cooling meters and combined heat/cooling meters

Fig. 8: Installation for circulation with throttle circuit, for example (flow sensor in flow direction before con-
trol valve / differential pressure regulator)
An installation set is included for meters with a Ø 5.2 × 45 mm temperature
sensor. This allows you to immerse the temperature sensor directly in an in-
stallation piece or a ball valve, for example.
1. Install the O-ring into the installation point using the enclosed mounting
aid/pin.
2. Place both halves of the plastic fitting around the 3 recesses on the temper-
ature sensor.
3. Press the screw connection together and screw the screw connection into
the installation point as far as it will go (tightening torque 3 ... 5 Nm).
Fig. 9: Mounting adapter set
Please note the following torques for tightening the screws and nuts on the
meter:
•
Screw on the device cover (Fig.1, No. 4): min. 1 Nm
•
All other screws: Hand-tightened to approx. 0.5 Nm
To prevent condensation from forming, observe the following installation instruc-
tions:
•
Install the cooling meter so that the black cover on the measuring tube
faces to the side or downwards.
•
Install the calculator separately from the volume measuring part, e.g. on the
wall.
•
Create a downwards loop with the connected lines.
•
Install the thermowells in such a way that the temperature sensors are hori-
zontal or vertical.
