Submerge the
hose 4. Submerge the suction hose.
■
Always keep the strainer suspended in the liquid being pumped.
■
Do not run the pump in less than 100 mm (4.0 in.) of water. At this level and
lower, water begins to form a funnel down to the bottom of the suction line
and strainer, allowing the pump to draw in air. The mixture of air and water
leads to a condition known as cavitation, which will quickly destroy the
impeller and the water chamber inside the pump housing.
Connect the
discharge
hose Connect the discharge hose (d) to the discharge port (e) .
Note: Lay the discharge hose as straight as possible. Avoid sharp bends and
turns.
Prime the
pump 5. Prime the pump. To do so:
a. Open the priming plug (f) .
b. With the suction hose submerged, fill the pump housing full of water.
NOTICE: Do not operate the machine without priming the pump. Extended dry
operation will damage the mechanical seal.
c. Close the priming plug.
