ing of this product, it may be necessary to work with
live electrical components. Failure to follow all electrical
safety precautions when exposed to live electrical com-
ponents could result in death or serious injury.
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
• 4TWX6024–60E1/G1
• 4A6H6024–60E1/G1
• 4A6H7024–060A1000AA
• 4TWR7024–060A1000AA
• 4TWX8024–060A1000AA

Procedure:
1. Remove valve cover, control box
cover, and access panel.
2. Using the blue wire supplied with the
kit and the existing wire nut, fasten
the stripped end of the blue wire
to the unit’s low voltage common
connection (B) at the low voltage
common thermostat wire connection.
See Figure 1.
3. Route the ring terminal end of the
blue wire along the same path as the
other low voltage wires entering into
the unit control box.
4. Using the screw supplied with the kit,
fasten the ring terminal end of the
blue wire to the control box utilizing
one of the screw starting dimples in
the control box. See Figure 2.
5. The ring terminal connection should
be a minimum of 1/4” from any other
electrical connection or terminal in
the box.
6. Install all covers and panel.
