The first step when operating the portable 15 gallon foam generating cleaning unit is to do which of the following?

• A. Release the Pressure
• B. Check the Air Filter
• C. Prime the Pump
• D. Engage the Blower

Answer: (A)

Relieving any stored pressure in the system is the first step because a pressurized setup can release liquid, foam, or parts suddenly when you start or open fittings. Depressurizing keeps you safe from unexpected discharges and makes it possible to inspect components, access fittings, and perform maintenance without the risk of a sudden burst. Once the system is depressurized, you can move on to checks and actions in a safer, orderly sequence—such as inspecting the air filter, priming the pump to ensure proper flow, and engaging the blower as needed for foam generation. The other steps are important for operation, but they should come after ensuring there is no residual pressure.
