The pump exhaust should be directed to a safe place, away from people,
animals and food.
• Optional kit is required for remote exhaust.
• Remove the muffler.
• Connect a hose to the exhaust port of the pump and install the muffler
at the end of the hose. Use a hose with the same diameter as the
exhaust port. (If the hose is more than 5 feet (1.5 m), consult your
dealer or Samson Corporation).
• Have a moat, a protective housing, etc. at the end of the hose.
To ensure that the air supply is sufficient to meet the demand of the pump,
the diameter of the pipe must be equal to the diameter of the supply port
of the pump. Choose auxiliary air treatment equipment and fittings with
sufficient airflow to exceed the air consumption of the pump. In addition,
This pump is self-priming.
To prime it the first time, you must connect the air pump supply to a low
pressure using the pressure regulators while keeping the outlet valve open.
When fluid begins to flow from the pump outlet, the pump is primed. For
