This section illustrates the basic components needed
to retrofi t a TS-DTU module into an existing dispenser.
This system can be installed in any “Non-Vapor or Vapor

loosening two screws on each door.

Figure 1: Open Door

2. Find the location where the DTU will be installed.

(The DTU will not be installed until step 21).
Examine the bottom of the electrical enclosure
to determine location of unused hole plugs and
choose the appropriate side of dispenser.

Figure 2: DTU Location

Note: Hole plugs beneath plastic catch pans cannot be

used as there is not signifi cant clearance to install
conduit fi ttings.

3. Remove lower dispenser door using key lock

closest to the hole plug chosen in step 2.
