Driveway Car Wash

Purpose:

As a part of our Senior Design Project, the client has identified the need for a driveway car wash. The car wash must be able to perform all operations needed for cleaning the car in a size restricted area of an average size driveway. The water supply needed for the wash must be compatible with a standard garden hose and spigot. The main function required of the apparatus is the application of a pre-wash cycle (water), wash cycle (soap), and a rinse cycle (water). Team Shine Driveway Carwash will help resolve the issue of a dirty vehicle and reduce time from using more conventional methods of cleaning a car, such as automatic car washes or “do it yourself” washes at home.

1.) Open box containing cabinet.

2.) Carefully place cabinet components on floor for assembly.

3.) Obtain casters(D) QTY(4) and install to bottom panel (E). Insert sixteen M6 x 16 hex flange bolts (AA) through the casters and into the bottom of the base cabinet. Tighten securely.

4.) Lock rigid casters QTY(2) and place base cabinet on floor. Obtain side panels (A & B) and install to the bottom panel (E) with two M6 x 16 hex socket head cap screws (DD)(security screws) and six M6 x 16 hex socket head screws (AA).

5.) Align front top beam (I) to the side panels (A & B) and install six M6 x 16 hex socket head screws (AA). Insert the screws by hand. DO NOT tighten.

6.) Repeat same process for back top beam (J).

7.) Attach the back panel (F) to the back of the cabinet with six M6 x 16 hex socket head screws (AA). Insert screws by hand. DO NOT tighten.

8.) Attach the top back panel (K) to the back of the cabinet with eight M6 x 16 hex socket head screws (AA). *Insert the top edge of top back panel under the back top beam. Insert screws by hand. DO NOT tighten.

9.) Attach the wood top (C) to the cabinet top by inserting four M6 x 166 hex socket head screws (AA) through the predrilled holes underneath the top beams (I & J) to the wood top (C). Tighten securely.

10.) Install door (G) by inserting the pins from the hinges on the door into the slot of the bottom hinges at the front of side panel (A).

11.) Install door (L) by inserting the pins from the hinges on the door into the slot of the bottom hinges at the front of side panel (B).

12.) Close the doors to see if the doors can tough the magnet completely. If not, adjust the cabinet's top and side panels to make sure the shape of the cabinet is square and flush. Once doors catch magnets completely, tighten top beams' and back panels' screws.

1.) Unbox Greenworks 1800 PSI electric pressure washer.

2.) Disassemble soap reservoir by removing QTY(2) fasteners.

4.) Slide QTY(1) heat shrink butt connectors to each wire on the flow sensor.

5.) Take 3 additional wires that will be spliced to the flow sensor wires and twist their ends so the wires strains intertwine with each other.

6.) Slide the connector over the splice wire so that the soldering portion of the connector sits on the connected strains of the two wires.

6.) Using the heat gun, apply adequate heat to the connectors until they shrink and engage tightly. Set aside for later use.

7.) Remove Solenoid and 1/4 connectors from packaging.

8.) Install 1/4 connectors to Solenoid using thread sealant tape and a 9/16 wrench.
