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.

Having described the invention, what is claimed is: 1. A method of indicating an operating characteristic of a solenoid used 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, comprising the step of: providing a first visually identifiable color-coded indicia associated with a housing containing the solenoid that corresponds to one of an air volume capacity or a temperature rating. 2. The method of claim 1 further comprising the step of: providing a second visually identifiable color-coded indicia associated with the housing that corresponds to an electrical characteristic of the solenoid. 3. The method of claim 2 wherein said first and second visually identifiable color-coded indicia are separate rings of color. 4. A method of indicating an operating characteristic of a solenoid used in the 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, comprising the steps of: providing a first visually identifiable color-coded indicia associated with a portion of a housing containing the solenoid and that corresponds to a first characteristic of the solenoid; and providing a second visually identifiable color-coded indicia associated with a different portion of the housing and corresponding to a second characteristic of the solenoid. 5. The method of claim 4 wherein the first and second visually identifiable color-coded indicia are separate rings of color. 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; a first visually identifiable color-coded indicia associated with a portion of said housing and corresponding to a first characteristic of said solenoid; and a second visually identifiable color-coded indicia associated with a different portion of said housing and corresponding to a second characteristic of said solenoid. 7. The solenoid assembly of claim 6 wherein said first and second visually identifiable color-coded indicia are separate rings of color. 8. The solenoid assembly of claim 6 wherein said solenoid has an input for receiving pressurized air and an output for providing pressurized air to said gun in response to an electrical signal.
