Adjusting Chain Length
The length of the suspension chain must be adjusted before the probe is installed.
Following the steps listed below:
1) Measure the distance from the top of the riser pipe to the bottom of the tank .
2) Look up the overall length of the probe in TABLE 2-1, or measure the overall length
of the probe.
3) Subtract the probe length from the distance measured from the top of the riser pipe
to the bottom of the tank, and then add 1/2" (12.7 mm) to this distance. This value
is the Total length of the chain including the split ring, and adjustment
eyebolt.
4) The suspension chain must be cut to the exact length required so that the
“Total length of the chain, split ring, and adjustment eye bolt” is equal to this value.
Mark the chain link to be cut.
5) Remove the split ring from the end of the chain and cut the chain to the correct
length. A pair of large diagonal cutters (dikes) will be helpful in cutting the chain.
WARNING Remove excess chain — DO NOT leave excess chain hanging from
the assembly within the riser pipe, failure to remove the chain may cause hazards!
6) After the chain has been cut, reattach the split ring to its end and measure the Total
overall length to make certain that it is within 1/2" (12.7 mm) of the correct value.
