DR-36/30 Nozzle Docking Receptacle

This is a Nozzle Docking receptacle to be used ONLY for Type-2 & Type-3 nozzle mounting purposes. There are no working internals, therefore it may only be used as a docking storage device.
NOTE: It shall not be used to dock a Type-1 nozzle.
Nozzle Types
Type 1– Nozzle with an integrated vent valve system. This vent valve is controlled by the single lever operation which will safely vent the gas trapped between the receptacle check valve and the nozzle inlet valve. After the venting process, the nozzle will disconnect from the vehicle’s receptacle.
Type 2– The vent valve operating mechanism is external to the nozzle. Venting is required prior to disconnection of this type of nozzle.
Type 3– The fueling hose is automatically depressurized below 50psi (3.4Bar) at dispenser shutdown. The nozzle will vent low pressure gas between the receptacle check valve and the nozzle inlet valve.
NOTE: This device shall not be installed on a vehicle nor be connected to a pressurized source of any type.
