7. For tanks less than 13" tall, a single long sender is used. The sender ends
should be 1/4" to 3/4" away from the top and bottom of the tank, to allow for
the thickness of the tank top and bottom and any bows in them (see the
diagrams). The senders are calibrated to account for this distance from
the bottom of the tank. The sender is cut to the nearest even 1.5 inch in
length, for example, a system with a tank height of 11.75 inches, cut the
sender to be 10.5 inches long, this allows 5/8" at each end when the
sender is centered vertically on the tank. IMPORTANT: Do not cut the
sender shorter than 4-1/2 inches! The sender will not work if it is cut
less than 4-1/2 inches. Proceed to step 9.
8. For tanks greater than 13" tall, two stacked long senders are used. The
sender ends should be 1/4" to 3/4" away from the top and bottom of the
tank, to allow for the thickness of the tank top and bottom and any bows in
them (see the diagrams). The senders are calibrated to account for this
distance from the bottom of the tank. In addition, there needs to be a gap
of 1/16" to 1/8" to between the two senders. Therefore total length of both
senders will be: tank height -1/4"-1/4"-1/8", then rounded down to the
nearest 1.5 inches. The top and bottom senders should be approximately
the same length for best results. For example, if the tank height is 22",
then 22"-1/4"-1/4"-1/8"=21 3/8", so the total length of both senders will be
21 inches. Make both senders 10.5" long. Proceed to step 9.
9. To make the senders the right length (assuming they are too long) they will
need to cut off with a pair of scissors. The end to be cut is the bottom end,
which is the opposite end from the top where the wires come out (see the
diagrams). DO NOT cut the sides, and DO NOT cut the sender shorter
than 4-1/2 inches (long sender) or 4" (short sender). The cut must be in
between the sensor pads, and the cut must be made parallel to the existing
bottom end. Double check your measurements, if the sender is cut too
short, it cannot be lengthened.
10. The senders need to be programmed so they know which tank they are on.
This is done by selectively cutting off the tabs on the top of the sender.
See the chapter entitled "SENDER PROGRAMMING" and the section "To
program the sender for the correct tank" for details.
11. For two stacked sender systems, the senders need to be programmed so
they know that they are being used as top or bottom senders. See the
chapter entitled "SENDER PROGRAMMING" and the section "To program
the sender as top or bottom" for details.
12. Once the sender is cut to length and programmed, carefully peel the
backing paper off the adhesive. Do this slowly to prevent the adhesive
from being ripped off the sender, and to prevent the backing paper from
ripping. Be careful not to bend the sender sharply in the process. Position
