Be sure to use a suitable seal. Do not install the seal using tools or pointed/sharp objects. Ensure that the
sealing surfaces on the device and the measuring point are clean and intact. Only use straight (not tapered)
G ¼ external threads with the PAC50. Only use fittings with axial sealing at the outer flange, with a maximum
insertion depth of 9 mm. Using incorrect connection threads may damage the device. Avoid tilting the thread
when inserting the screws. You should maintain a tightening torque of 1.5 Nm ±0.5 Nm. This value must not
be exceeded. The unused G ¼ female thread must be sealed using the supplied dummy plug. Insert the seal
for the dummy plugs and tighten to 1 Nm ±0.3 Nm.
