SETUP
4.1.
Pump placement.
4.1.1.
For best pump performance, place the pump near the water level, and
use hoses that are no longer than necessary. This will enable the pump
to produce the greatest output with the least self-priming time.
4.1.2.
As head (pumping height) increases, pump output decreases. The length,
type, and size of the suction and discharge hoses can also significantly
affect pump output.
4.1.3.
Discharge head capability is always greater than suction head capability,
so it is important for suction head to be the shorter part of total head.
4.1.4.
Minimizing suction head (placing the pump near the water level) is also
very important for reducing self-priming time. Self-priming time is the
time it takes the pump to bring water the distance of the suction head
during initial operation.
4.2.
Suction head installation.
4.2.1.
Use the hose, hose connector and hose clamp provided with the pump.
The suction hose must be reinforced with a non-collapsible wall or
braided wire construction to prevent suction hose collapse.
4.2.2.
The suction hose should be no longer than necessary. Pump
performance is best when the pump is near the water level, and the
hoses are short.
4.2.3.
Never use a suction hose with an inside diameter less than 25 mm (1
inch).
4.2.4.
Use a hose clamp to securely fasten the hose connector to the suction
hose in order to prevent air leakage and loss of suction. Verify that the
hose connector sealing washer is in good condition.
4.2.5.
Install the strainer (provided with the pump) on the other end of the
suction hose, and secure it with a hose clamp. The strainer will help to
prevent the pump from becoming clogged or damaged by debris.
4.2.6.
Securely tighten the hose connector on the pump suction port.
