A liquid dispensing system and methods including color-coded visual indicia to assist an operator in the proper selection of the components and in the configuration of those components in the system during setup, maintenance and diagnostics. Color-coded indicia is also provided to assist an operator in the proper selection of a solenoid for use in a particular application. Various components of the liquid dispensing system, such as the melter unit, controller, hoses, electrical cordsets and solenoid, include visually identifiable color-coded indicia on the surfaces of the components, such as color-coded rings, bands and characters, to assist the operator in the component selection and configuration processes.

What is claimed is: 1. A solenoid assembly for use in a liquid dispensing system having a dispensing gun including a valve movable relative to a dispensing orifice of the gun in response to operation of the solenoid assembly for dispensing liquid, the solenoid assembly comprising: a housing: a solenoid disposed within said housing, said solenoid having an input for receiving pressurized air and an output for providing pressurized air to the gun in response to an electrical signal; and a first visually identifiable color-coded indicia associated with said housing and corresponding to one of an air volume capacity or a temperature rating of said solenoid. 2. The solenoid assembly of claim 1 further comprising: a second visually identifiable color-coded indicia associated with said housing and corresponding to an electrical characteristic of said solenoid. 3. The solenoid assembly of claim 2 wherein said first and second visually identifiable color-coded indicia are separate rings of color. 4. A liquid dispensing apparatus for dispensing liquid, comprising: a liquid supply source; a dispensing gun fluidly connected to said liquid supply source and having a valve movable relative to a dispensing orifice of said gun; a solenoid operable to control movement of said valve, said solenoid having an input pneumatically coupled to a source of pressurized air and an output pneumatically coupled to said dispensing gun; and a first visually identifiable color-coded indicia associated with said solenoid and corresponding to one of an air volume capacity or a temperature rating of said solenoid. 5. The dispensing apparatus of claim 4 further comprising: a second visually identifiable color-coded indicia associated with said solenoid and corresponding to an electrical characteristic of said solenoid. 6. A solenoid assembly for use in a liquid dispensing system having a dispensing gun including a valve movable relative to a dispensing orifice of the gun in response to operation of the solenoid, the solenoid assembly comprising: a housing: a solenoid disposed within said housing, said solenoid having an input for receiving pressurized air and an output for providing pressurized air to said gun in response to an electrical signal; a first visually identifiable color-coded indicia associated with said housing and corresponding to a first characteristic of said solenoid; and a second visually identifiable color-coded indicia associated with said housing and corresponding to a second characteristic of said solenoid, wherein said first and second visually identifiable color-coded indicia are separate rings of color; wherein said first visually identifiable color-coded indicia corresponds to one of an air volume capacity or a temperature rating of said solenoid. 7. The solenoid assembly of claim 6 wherein said second visually identifiable color-coded indicia corresponds to an electrical characteristic of said solenoid. 8. A liquid dispensing apparatus for dispensing liquid, comprising: a liquid supply source; a dispensing gun fluidly connected to said liquid supply source and having a valve movable relative to a dispensing orifice of said gun; and a solenoid assembly according to claim 6 operable to control movement of said valve. 9. The dispensing apparatus of claim 8 wherein said second visually identifiable color-coded indicia corresponds to an electrical characteristic of said solenoid.
