NEMA -4X (-4X) Figure 1 Installation Carrier’s standard Immersion sensors are made to install into a ½” NPT female thread. Typically a Threadolet or Tee is installed into the pipe, but a hole can also be drilled and tapped. Figure 2 The pipe/system will need to be drained, unless a Hot Tap is being used. - Page 3 Thermistor, Immersion Installation and Operation #NSA-A/CP-I-2.5-4X, NSA-A/CP-I-4-4X, NSA-A/CP-I-6-4X, NSA-HH/CP-I-2.5-PB-C, NSA-HH/CP-I-4-PB-C NSA-HH/CP-I-6-PB-C – 11/15/2019 Elbow Assembly Tee Mount Assembly Figure 4 Figure 3 Temperature Wiring Figure 5 Specifications subject to change without notice.

Page 4: Wiring Instructions
PRECAUTION Do not run the wiring in any conduit with line voltage (24/120/230 vac). Open the cover of the enclosure. Carrier recommends 16 to 26 AWG twisted pair wires or shielded cable for all sensors. Signal wiring must be run separate from low and high voltage wires (24/120/230VAC). These Carrier thermistors and RTD temperature sensors are both non-polarity and non-position sensitive. -
