Scope:
This additional EMI (Electromagnetic Interference) pro-
tection kit is developed to reduce the potential effects
of EMI on the pressure transducers.
Overview:
This Kit is to be used on the specific outdoor condens-
ing units (shown at left) that have an EEV flow control
device. This Kit provides an additional EMI grounding
path, to help reduce the potential interference dam-
age that can be caused to the outdoor units’ pressure
transducer. Install this kit when replacing a pressure
transducer on the product listed in the heading of these
installation instructions.
Application:
This Kit is to be used on the following outdoor
condensing units that have an EEV flow control device:
• 4TWR6024–060A1
