1. Attach the thermowell to the pipe or process container wall. Install and tighten
thermowells before applying process pressure.
2. Attach necessary extension nipples and adapters to the thermowell. Seal the
nipple and adapter threads with silicone tape.
3. Screw the sensor into the thermowell. Install drain seals if required for severe
environments or to satisfy code requirements.
4. Verify the transmitter failure mode switch.
5. Pull the sensor wiring leads through the universal head and transmitter. Mount
the transmitter in the universal head by threading the transmitter mounting
screws into the universal head mounting holes.
6. Mount the transmitter-sensor assembly into the thermowell. Seal adapter
threads with silicone tape.
7. Install conduit for field wiring to the conduit entry of the universal head. Seal
conduit threads with silicone tape.
8. Pull the field wiring leads through the conduit into the universal head. Attach
the sensor and power leads to the transmitter. Avoid contact with other
terminals.
