Hose And Hose Retractor; Bleeding Product Lines (Remote Dispensers) - Wayne Ovation Installation & Operation Manual

2.7 Hose and Hose Retractor

Hose assemblies should be U.L. Listed and installed in accordance with the manufacturer's instructions. To
ensure a proper joint, wash all cutting oil off the threads and use a U.L. classified gasoline-resistant pipe joint
sealing compound. Place the compound on male threads only; be careful not to get any excess compound
inside fittings. Install the fixed end of the hose to the dispenser outlet; secure according to the instructions of
the sealing compound and hose manufacturers. Install the swivel end of the hose or other swivels to the noz-
zle according to the manufacturer's instructions.
Exception: Do not use the sealant on balanced or inverted hoses used with vapor recovery.
NFPA code requires a Listed emergency breakaway device, designed to retain liquid on both sides of the
breakaway point, must be installed on each hose dispensing Class I liquids; these devices must be installed
and maintained per the manufacturer's instructions. Refer to your state and local codes for breakaway device
requirements that apply to your installation.
On E85 Ovation dispensers, all hoses, nozzles, breakaways, etc., containing the Ethanol fuel must be Ethanol
compatible. See the information in Section 1.1 on page 1.
On Wayne vapor recovery dispensers all hoses, nozzles, and breakaways, etc., must be CARB certified.
Hose Retractor: Caution!: On dispensers equipped with the Hose Retractor option, the hose clamp must
be mounted upstream of the breakaway device to avoid damage to the dispenser in the event of a drive-off.
The combined hose, breakaway, and whip maximum lengths are listed below.

WARNING
Use only Listed hoses and nozzles. Continuity must be present between the dispenser outlet and nozzle
spout to prevent static discharge while fueling. Continuity must be checked for each outlet/hose assem-
bly to insure that the nozzle is grounded. Failure to do so may result in a hazardous condition that could
cause serious injury.
