Abstract

Disclosed examples relate to a cleaning assembly kit for a heat exchanger and a method of using thereof. In at least one example, the cleaning kit assembly for cleaning an inner volume of a heat exchanger comprises: a cover lid couplable to an opening of a body of the heat exchanger; and a manifold assembly comprising, a main fluid conduit including (i) a fluid inlet couplable to a cleaning fluid source, and (ii) a fluid outlet couplable to the inner volume of the heat exchanger; a drainage conduit fluidically coupled to the main conduit at a coupling juncture, and comprising a drainage outlet; and valve system including, an inlet valve located inside the main conduit and disposed between the inlet opening and the coupling juncture; and a drainage valve located inside the drainage conduit, between the drainage outlet and the coupling juncture.

1 . A cleaning kit for a heat exchanger comprising:
 a cover lid couplable to an opening of a body of the heat exchanger; and   a manifold assembly comprising,
 one or more conduits comprising (i) a fluid inlet couplable to a cleaning fluid source, (ii) a fluid outlet couplable to an inner volume of the heat exchanger, and (iii) a drainage outlet; and 
 a valve system disposed inside the one or more conduits including, (i) an inlet valve, and (ii) a drainage valve. 
   
     
     
         2 . The kit of  claim 1 , wherein the kit is operable in one of a filling mode and a drainage mode, wherein,
 in the filling mode, the valve system is adjusted to a filling configuration to fill the inner volume of the heat exchanger with cleaning fluid; and   in the drainage mode, the valve system is adjusted to a drainage configuration to drain the inner volume from the cleaning fluid.   
     
     
         3 . The kit of  claim 2 , wherein in each of the filling and drainage modes, the cover lid is coupled to the opening of the body of the heat exchanger. 
     
     
         4 . The kit of  claim 2 , wherein in the filling configuration,
 the inlet valve is opened to fluidically couple the fluid inlet to the fluid outlet, thereby permitting cleaning fluid to flow through the manifold assembly from the cleaning fluid source into the inner volume of the heat exchanger, and   the drainage valve is closed to fluidically decouple the fluid inlet from the drainage outlet.   
     
     
         5 . The kit of  claim 2 , wherein in the drainage configuration,
 the drainage valve is opened to fluidically couple the fluid outlet to the drainage outlet, thereby permitting cleaning fluid to drain from the inner volume of the heat exchanger; and   the inlet valve is closed to fluidically de-couple the fluid inlet from the fluid outlet.   
     
     
         6 . The kit of  claim 1 , wherein the manifold assembly further comprises an auxiliary outlet, and the valve system further comprises an auxiliary valve located inside the main conduit between the fluid inlet and the auxiliary outlet. 
     
     
         7 . The kit of  claim 6 , wherein in each of the filling and drainage configurations, the auxiliary valve is closed. 
     
     
         8 . The kit of  claim 7 , wherein the assembly is further operable in an auxiliary tool mode where the valve system is adjusted to an auxiliary tool configuration whereby,
 the auxiliary valve is opened to fluidically couple the fluid inlet to the auxiliary outlet, thereby allowing fluid to flow through the manifold assembly from the cleaning fluid source to the auxiliary tool; and   the inlet valve is closed and the drainage valve is either opened or closed.   
     
     
         9 . The kit of  claim 7 , wherein in the auxiliary tool mode, the cover lid is removed from the opening of the body of the heat exchanger. 
     
     
         10 . The kit of  claim 2 , wherein the cover lid includes an external surface and an internal surface, and in a coupled position to the heat exchanger, the external surface is directed away from the inner volume, and the cover lid further comprises,
 a fluid flow meter extending from the external surface and, in the coupled position, fluidically couples to the inner volume of the heat exchanger through an outlet opening extending through the cover lid, and   wherein, in the filling and drainage modes, the fluid flow meter indicates a level of cleaning fluid inside the inner volume of the heat exchanger.   
     
     
         11 . The kit of  claim 1 , wherein the heat exchanger is for use with water boilers. 
     
     
         12 . The kit of  claim 11 , wherein the heat exchanger is a condensing heat exchanger. 
     
     
         13 . The kit of  claim 1 , wherein the cover lid is coupled to the manifold assembly. 
     
     
         14 . The kit of  claim 13 , wherein the cover lid includes a lower coupling portion that couples to a conduit of the manifold assembly. 
     
     
         15 . A method of using a cleaning kit to clean an inner volume of a heat exchanger, the cleaning kit assembly comprising a cover lid and a manifold assembly, the method comprising:
 coupling each of the modified cover lid and the manifold assembly to a body of the heat exchanger;   operating the cleaning kit in a filling mode by adjusting a valve system, of the manifold assembly, to a filling configuration;   filling the inner volume of the heat exchanger with cleaning fluid;
 operating the cleaning kit in a drainage mode by adjusting the valve system, of the manifold assembly, to a drainage configuration; and 
   draining the inner volume of the heat exchanger from cleaning fluid.
