install the product.

Installing the Transmitter

After selecting a suitable measurement location, follow the procedure

below to install the transmitter:

1. Remove the yellow transport protection cap from the transmitter.

Figure 3 Removing the Transportation Protection Cap

2. Prepare the sealing of the connection:

- If the transmitter has a parallel ISO G1/2" thread, place the

sealing ring at the base of the thread. Always use a new

sealing ring; do not re-use a previously installed one.

- If the transmitter has an NPT 1/2" thread, do not use the

sealing ring. Instead, apply PTFE tape or suitable paste

sealant to the thread. Follow the application instructions of

the sealant.

3. Make sure that the threads on the mounting point are of the correct

type, and fasten the transmitter to the measurement point. Use your

hands to turn the probe until it feels tight. Do not use force at this

point, and check that the sealing ring

(if used) remains centered.
