🔍 Key Concepts

• This is a self-cleaning (self-desludging) purifier bowl; desludging is started by admitting operating water to a hydraulic space under the bowl bottom. • Automatic operation uses a solenoid valve, while manual operation uses a hand valve, but both send water to the same inlet point on the machine. • On the sectional drawing, the operating water inlet is shown at the base of the bowl, feeding the hydraulic mechanism that opens the sludge ports.

💭 Think About

• Look at where the operating water must enter to lift or move the sliding bowl bottom that opens the sludge ports. Which label is pointing to that point of entry? • Trace from the automatic/solenoid valves at the top downwards: where would their discharge line terminate on the lower part of the purifier? • Which of F, P, Q, or R is associated with a pipe connection rather than a structural bowl part or discharge port? That connection is what starts the desludging sequence.

✅ Before You Answer

• Identify which label shows an inlet connection at the base of the purifier, not a discharge or a fixed structural piece. • Confirm that the component you choose is logically where operating water pressure would act to move the sliding bowl bottom and open the sludge ports. • Make sure the part you pick can be controlled both automatically (solenoid) and manually (hand valve) by supplying or cutting off water to it.
