Pentair inline thermometer installation notes

1. Confirm that all 3 Pentair inline thermometer parts are on-hand.
1. brass well
2. plastic collar that fits in brass well
3. dial thermometer with extension rod that fits into plastic collar
2. Separate parts from each other. If the plastic collar is in the brass well, carefully remove it so as to not damage it.
3. Solder the tee fitting in line with the copper piping if it has not already been done.
4. Solder the brass well into the tee fitting with the well's hole facing outward. Have about 1/4inch of the well extending out of the fitting so as to not get any solder into the well's hole.
5. Let cool.
6. Check for leaks. If necessary, repeat soldering and cooling.
7. Insert plastic collar into brass well.
8. Insert thermometer's rod into collar.
