Quick Start Guide

August 2012
Installation recommendations
 Avoid installing near liquid entering the tank at the fill point
 Avoid heavy splashing on the forks.
Increasing the time delay reduces accidental switching
 Avoid installing near heat sources
 Ensure the fork does not come into contact with the tank/pipe wall, or fittings
 Allow a sufficient distance between product build-up on the tank wall and fork

Step 1: Physical installation
1. Install the 2120 according to standard installation practices, making sure to
correctly align the fork using the alignment notch or groove (Figure 6).
2. Use supports for extended fork lengths greater than 3.2 ft. (1 m) (Figure 5).
For the GL approval requirements, see reference manual 00809-0100-4030.
3. Close the housing cover and tighten to safety specification. Always ensure a proper
seal so that metal touches metal or plastic touches plastic, but do not over tighten.
4. Insulate the 2120 with Rockwool. See Figure 7 for clearances.
