Claim Text:
1. A portable coil cleaning and vacuum system, comprising: a frame; a fluid inlet; a fluid storage tank coupled to the frame; a first valve coupled to receive fluid from each of the fluid inlet and the fluid storage tank, the first valve being selectively operable to direct fluid received from one of the fluid inlet and the fluid storage tank to a first valve outlet; a second valve coupled to receive the selected flow from the first valve outlet, the second valve being selectively operable to direct the received fluid to one or more of (i) a fluid pump inlet, via a second valve outlet, (ii) a first chemical tablet container, via a second valve first chemical outlet, and (iii) a second chemical tablet container, via a second valve second chemical outlet; a first T-fitting coupled to receive fluid flow from each of the first and second chemical tablet containers and to direct received fluid flow to a first T-fitting outlet; a second T-fitting coupled to receive fluid flow from each of the second valve outlet and the first T-fitting outlet and to direct received fluid flow to the fluid pump inlet; a fluid pump coupled to receive fluid flow from the fluid pump inlet and to provide the received fluid flow to a fluid outlet, the fluid pump being selectively powered via engagement of a first electrical switch at a first switch position; the first chemical tablet container; and the second chemical tablet container, each chemical tablet container, comprising: a cylindrical body defining a plurality of integral support legs, a fluid inlet, and a fluid outlet, with each of the fluid inlet and the fluid outlet being in volumetric communication with an internal cavity defined by the cylindrical body, the internal cavity being open at a first end of the cylindrical body; a chemical tablet cup removably disposed within the internal cavity, the chemical tablet cup defining an interior void to accept a chemical tablet and a perforated rim defining a volumetric communication between the internal cavity of the cylindrical body and the internal cavity of the chemical tablet cup; and a removable cap coupled to the first end of the cylindrical body to selectively seal the internal cavities at the first end.
