8. Mount the USHX onto the access
fitting. Turn the USHX housing
clockwise by hand until some
resistance is met and then use 7/16”
and 9/16” wrenches in tandem as
shown below in Figure 15 to further
tighten the USHX connection. This
will ensure that the brazed joint is
not damaged by the torque of the
tightening.
9. Attach the wiring harness (10-pin
connector) to the USHX as shown
below in Figure 15.
a. If the USHX is located in a
wet or potentially wet
environment, apply silicone
grease inside the 10-pin
connector of the wiring
harness.

10. Install the thermistor at the outlet of
the evaporator and close to the
access fitting using a zip tie, as
shown below in Figure 16. The
thermistor should be located at either
the 10 o’clock or 2 o’clock position
only.
a. Ensure that the thermistor
wire is not tied down to the
tubing. The zip tie should
only be tied around the
thermistor body.
b. Apply thermal grease
between the thermistor and
the copper line to obtain the
most accurate temperature
readings.
