Loosen the G3/4 female thread connector, and place it on the temperature probe and
align them to ensure that each thread can be connected smoothly.
Threaded connection procedure
1. Wrap the G3/4 thread connection with sealing tape.
2. Screw on the union to the G3/4 thread connection part and make sure that it is
secure.
3. Wrap the male thread connector with sealing tape.
4. Insert the packing in the union, and install NMT81.
5. Tighten the union by hand until it is fully screwed in.
6. Remove the cover and confirm that both sides of the cables have enough length to be
connected.
7. After connecting the cables and adjusting the position of NMT81, tighten the union
by hand and then make a 1/8 rotation with a wrench to secure it in place.
This completes the threaded connection procedure.
