8.1 Installation

1. The MARS should not be installed on the tower and power should not be connected. This

is important to prevent electrical shock and to avoid damage to internal wiring, as well as

to the fan blades.

2. Connect the probe cable to the probe.

3. To simplify routing the probe cable and installing the probe in the vent tube, feed a piece

of string weighted at the end (with a nut, for example) through the horizontal tube and

down through the vent tube.

4. Tie the string to the probe cable and pull the string from the opposite end to guide the

cable up through the vent tube and into the horizontal tube.

5. Form a loose loop of cable at the base of the probe, and secure it with a cable tie so that

the cable forms a U.

6. With the filter end of the probe pointing up, grasp the loop of cable at the base of the

probe and raise the probe up into the vent tube.

7. When you feel the probe make contact with the mount, move it side to side as necessary

until it slides into the mount opening.

8. Slide the probe into the mount until the bottom of the probe is 2–3 inches above the

mouth of the MARS vent tube.

9. While holding the probe in place, tighten the mounting screws just enough to secure the

probe, but do not overtighten. Over-tightening the screws will damage the probe.

10. Pull the remaining slack out of the cable, keeping the cable as straight as possible.

11. Tighten the strain relief until the cable is securely sealed.
