7.2 Preparations (requirements for the installation location)

A check on suitability of the device and of the thermowell that may be required for the medium to be measured,
the arrangements in the scope of measurement range and the extent of the protection against special conditions
such as vibrations.
A bracket must be installed to support the gauge if the metering pipe is not able to provide adequate support.
Devices with a blow-out require a minimum spacing to the rear (20 mm).
The operating temperature range is -30°C to + 80 °C.
7.3 Mounting/Installation
Using appropriate accessories, the device can be installed on flat walls, mounting plates, on pipes or in panels or
boards.
Ex works, the device is supplied and calibrated for vertical installation.
If the installation location deviates from the vertical (max. ± 5°), the zero setting on the indicator must be corrected
(see 7.4.1 Zero point adjustment).
7.3.1 Every angle connection (optional)
Only adjust the every angle connection if this is necessary during fitting or
removal.
Use the every angle connection to place the sensor in the correct position
prior to installation, proceeding as follows:
Position the thermometer housing in a straight alignment (Position "C")
Using the screws marked "A", loosen until the joint can be turned freely
through 180° on the lower part of the housing and the sensor.
Hold the thermometer housing firmly with one hand, and with the other hand
turn the joint piece until the inner part of the joint is showing in the desired
direction of bend.
Firmly tighten the aforementioned Screws "A" again.
Loose the screws marked "B" and move the joint into the desired direction of
bend.
Firmly tighten the aforementioned Screws "B" again.
7.3.2 Process connection
Connection only to be undertaken by authorized and qualified specialist staff.
Use only with the mechanical process connection provided – regarding the configuration, see order code on the
device type label.
When connecting the device without using a thermowell, the pipes must be depressurized.
Do not allow any mechanical force to be applied to the stem; in particular, pay attention to matching the "S"
lengths of the thermometer and the thermowell, to avoid contact against the base of the thermowell.
A thermal transfer medium (heat conducting paste) in the thermowell improves the reaction time and reduces the
measurement error caused by the thermal transfer.
The minimum capillary line radius is 40 mm (1 ½"). Place it so that it will be protected from damage. Should the
capillary line be too long, coil the surplus neatly at a convenient point but "DO NOT CUT IT."
The thermometer system (Bourdon tube, capillary line and temperature sensing bulb) must not, under any
circumstances be taken apart, or the capillary line cut.
Safety notice: Only mount using the correct open-jawed wrench, and do not twist the device itself.
Do not insert moist or oily stems into hot thermowells.
