First, a spot must be selected that is convenient for the users of the system and is appropriate from a wiring point of
view. Refer to Figure 1 for mounting location restrictions. Also refer to the National Electrical Code for
specific information on the location of classified areas in and around service stations and fuel dispensing
equipment. Pay particular attention to the layout of conduit runs and the placement of ac conduit and low
voltage conduit. Care should be taken to provide as much isolation as possible between these wire/conduit
runs and any sources of electrical noise.
The VST Fuel S-810 (DET) may be mounted using either of two methods. The first method is mounting the DET
on the top of a 2 inch pipe x 55” (approx.) height. The DET is simply screwed onto the pipe and after
being positioned for operation the two set screws in the mounting hub are tightened to prevent the DET
from turning during normal operation. The second method consists of removing the mounting hub
normally supplied with the DET and using the gasket and bolts to fasten the DET to the VST Pedestal. The
VST Pedestal must be anchored to the island using six 1/4 inch bolts and appropriate concrete anchors.
Refer to Figures 2 and 3 for detailed information on the space requirements and the bolt pattern required for
mounting the pedestal. Note that the suggested clearance requirements in Figure 2 are for operation and
service of the VST Fuel S-810.
