Autmatic sampler PROGRAMMING INSTRUCTIONS sheet. Instructins will be n a single sided sheet and will be lcated adjacent t the sampler during the event. The event scring will be based n the fllwing: The time taken t cmplete the event. The leakiness f the wet pipe after being repaired. The wet pipe cnnectins will be checked fr water tightness at 3 psig fr 30 secnds. The accuracy f the autmatic sampler prgramming and sample taking. Cmpliance with all prvided instructins. Ability t perfrm the event safely and in accrdance with all standard field safety guidelines. 2017 Operatins Challenge Cllectin Systems Event 2
REQUIRED PROCEDURES 1) A three-minute event set-up perid is prvided t ensure that all necessary tls and equipment are prvided and satisfactry. It is the team s respnsibility during this time t cmplete the fllwing: 2) Check and cnfirm that all bands t be used in the event are in satisfactry cnditin. 3) Mark the wet pipe, if desired (nly the wet pipe). 4) Bands will already be placed lsely arund cuplings. 5) Cnfirm the pipe table and clamps are apprpriate fr the team. 6) Oversee lubricatin f the saw blades and hle saw, if desired. 7) The Inserta Tee must be cmpletely put tgether (defined by the PVC being seated in the rubber cupling apprpriately t the nted insertin pint with the stainless band arund the rubber cupling withut falling ff) r cmpletely apart inside the tl bx. 8) At the end f the three-minute set-up perid, all tls and equipment must be placed flat in the tlbx. Nne f the tls can be stacked n tp f each ther (N verlapping f any cmpnent in the tlbx) r left leaning against the tlbx. Leaning is defined as supprt f the vertical walls f the tlbx is necessary t keep the item in the current psitin. The judges will cnfirm the tl bx is set apprpriately befre the event begins. If it is nt set apprpriately, the Team Captain will be asked t reset the bx and latch the padlck. If the bx is nt set by then end f three minutes, a penalty will be assessed. 9) Each team member is required t wear all f the apprved safety gear thrughut the event, and cmpete in a safe manner. 10) The team member(s) prgramming the sampler may remve their safety glves, but nly while prgramming the sampler and in the sampler area. Glves must be put back n prir t leaving the sampler area. The sampler area is apprximately 4 ft x 5 ft and will be marked with tape n the flr surrunding the sampler. 11) The PVC pipe sectins strapped t the tables may nt be mved laterally by the cmpetitrs. 12) The 4.5-inch hle must be drilled in the sectin riginating frm the dry PVC pipe, using the hle saw prvided. 13) Install the Inserta Tee using the fllwing steps: Cre a 4.5-inch hle with the hle saw prvided and clean the edges. Install the rubber sleeve with the gld band perpendicular t the pipe. Check t be sure the inside and utside segments are flush t the pipe. Place the stainless steel band ver the rubber sleeve, but d nt tighten. Spray the sap slutin inside the sleeve and n the plastic hub. Align vertical red line n the plastic hub with the gld line n the sleeve and insert by hand. Place a wd blck n the plastic hub and drive the hub int the sleeve with the hammer. The hub shuld be installed s that the hrizntal red line is at the tp f the rubber sleeve. Tighten the stainless steel band, near the tp f the rubber sleeve. 2017 Operatins Challenge Cllectin Systems Event 3
14) The lengths f PVC pipe must be cut ut using the LENOX saws prvided. All cuts must be cmpleted within the framewrk f the pipe table. 15) The autmatic sampler must be prgrammed crrectly using the data prvided n the attached instructin sheet. All teams shall enter the site ID as the tw digits 15 in the first tw available clumns f the site ID entry (far left). The sampler will be reset t Factry Defaults between each team s run f the event. 16) When replacing tls in the tlbx, the tls must be placed in the tl bx and nt thrwn r drpped frm a level abve the height f the sides f the bx. The tlbx lid is t be clsed and latched with the padlck. The free end f the lck shackle must be placed thrugh the hasp and ver the bdy f the lck. A majrity f the shackle s free end must be within the plane f the lck bdy. D nt clse the lck. 17) The team captain will determine the end f the event by signaling the judges bth visually and audibly.

The judges will: Recrd the elapsed time. The average f the stpwatches will be used t set the raw time. Check the sewer service replacement sectin fr water tightness. The wet PVC pipe will be allwed t fill until water flws frm the utlet end. At this pint, the discharge valve will be clsed and the pressure increased t 3 psi. Time penalties will be added fr any leakage that ccurs within 30 secnds. The team captain will be asked t witness the leak test. Check the accuracy f the prgramming f the autmatic sampler and verify that a prper sample was taken. Any penalties and the assciated penalty times must be apprved and signed by all f the judges.
