Installing Breakaways, Hoses, Swivels, and Nozzles Installation
Note: It is important that Teflon tape is not used on threaded connections. Use a UL-approved
sealant suitable for the fuel involved, only where sealing is required (not used for

O-rings). Castings may fracture during assembly or later, if Teflon tape is used.
To install breakaways, hoses, swivels, and nozzles, proceed as follows:
1 Attach the swivel (if used) to the nozzle. Follow the swivel manufacturer’s instructions.
2 Assemble and attach the breakaway whip hose to the swivel or nozzle. Follow the hose
manufacturer’s instructions. For units with hose retrievers, refer to
“Units with Hose
Retrievers” .
3 Assemble the breakaway to whip the hose. Follow the breakaway manufacturer’s instructions.
4 Assemble the hose to the breakaway, followed by the unit outlet casting. Follow the
breakaway manufacturer’s instructions. The hose clamp must connect between the breakaway
coupling and pump/dispenser outlet.
Units with Hose Retrievers
For units with hose retrievers, attach the retriever clamp to a long hose that is positioned to
allow maximum extension of the hose, yet prevent a trip hazard. Use hose breakaway
couplings that are installed as per the manufacturer’s instructions
.
WARNING
Failure to position hose clamps correctly may prevent the operation of the breakaway
coupling, resulting in the unit being pulled off an island during a drive-off, with fuel being
spilled. This can result in serious injury or death. Ensure that the hose clamp is installed
between the breakaway coupling and unit outlet casting. This ensures that the
breakaway functions properly.
