Abstract
An injection type chemical sprayer (30) including interior and exterior cleaning systems. The interior cleaning system can include a rinsing nozzle (58) located within the concentrated chemical tank (52). Rinsing nozzle (58) can be selectively connected to the pressure side of a spray pump (34). The chemical rinsate can be dispensed by means of a rinsate pump (64) in combination with a rinsate nozzle (66). Following the rinsing operation, the concentrated chemical tank (52) can be reconnected to an injection pump (56), and then the concentrated chemical tank (52) can be filled with clean water which is then pumped through the injection system to completely flush it of the chemical being injected. System (30) also preferably includes an exterior cleaning system which can include a spray gun (60) selectively connected to the pressure side of the spray pump (34).
