Required Tools

• Power screwdriver with 1/4-inch (6 mm) hex

extension or medium flat-blade screwdriver

• 1-1/4 inch (32 mm) open-end wrench or

equivalent adjustable wrench

• Medium crescent wrench

• Pipe sealant

• Wire stripper

Expected Installation Time

3 hours

Prerequisites

• The appropriate field wiring within the

maximum wiring run length for the individual

field panel or equipment controller must be in

place.

NOTE: All wiring must comply with National

Electric Code (NEC) and local

regulations.

• A 1/2-inch (13 mm) NPT mounting coupling

must be installed in the piping system at the

sensor location. Figures 1 and 2 show two

types of installation in a pipe joint.

Instructions

NOTE: It is not recommended or necessary to

separate the well and the pulling elbow to

install the sensor assembly. The pulling

elbow should only be removed to replace a

damaged or defective sensing element.

1. Clean any dust away from the coupling for the

well.

2. Apply pipe sealant to the threads of the well and

insert the entire sensor assembly into the

coupling.

3. Hand-tighten the sensor assembly. Finish

tightening the assembly by using a 1-1/4 inch

(32 mm) open-end wrench. Tighten the

assembly until the outlet of the pulling elbow is

aligned with the controller.

4. Pull the field wiring to the pulling elbow and

connect the field wiring to the Sensing Element.

See Figure 4.

NOTE: In applications where condensate may

accumulate (chillers, low temperature

sensing, etc.) seal all wire connections

with RTV adhesive (ordered separately,

P/N 535-495).

5. Connect the field wiring at the controller.

The installation is now complete.
