System and method for cleaning contaminant collection equipment

A wash system for cleaning the exposed surfaces of a contaminant collection device, comprising:

• a source of pressurized cleaning solution;
• a rinse appliance comprising a tank, a sampling head receptacle and a separator receptacle, the separator receptacle comprising:
• a vacuum pathway rinse port centered within a rinse chamber, and having a first sealing surface located therein;
• and
• the rinse chamber surrounding the vacuum pathway rinse port and having a collection chamber rinse nozzle formed therein;
• a sampling head of the contaminant collection device installed in the sampling head receptacle with a sampling head vacuum orifice supported above the tank;
• and
• a separator of the contaminant collection device installed in the separator receptacle with a collection bottle stem sealing against the first sealing surface to establish communication with the vacuum pathway rinse port, and with a collection chamber surrounding the collection chamber rinse nozzle,
• wherein activation of a vacuum pathway rinse causes pressurized cleaning solution to flow along a first flow path against a plurality of interior surfaces of the sampling head and a vacuum tube that couples the sampling head to an interior of the collection bottle stem, and
• wherein activation of a collection chamber rinse causes pressurized cleaning solution to flow along a second flow path against the collection bottle stem and a plurality of interior surfaces of the collection chamber and a separator filter installed therein.
