OPERATION

Discharge Hose Connection
Use a commercially available hose, hose connector, and hose band. A
short, large diameter hose will provide lower fluid friction and improve
pump output. A long or small diameter hose will increase fluid friction
and reduces pump output. Never use a hose size smaller than the
discharge port diameter.
NOTICE
If a discharge hose is used that has a smaller inside diameter than the
port size, the pump case may be damaged. To avoid pump damage,
always use the correct size hose.
Tighten the hose clamp to prevent the hose from disconnecting under
high pressure.
Pump Priming
Pump priming is not required if the vertical distance from water to the
pump (suction head) is less than 14 feet on WDP20X or 16 feet for a
WDP30X. The suction head can be increased to 21 feet for the
WDP20X or 24 feet for the WDP30X by priming the pump.
To prime the pump, remove the air cushion chamber cap. Grasp the
suction hose next to the suction fitting and lift the hose about 1 foot off
the ground. Pour about 1 gallon of water into the pump case through
the air cushion chamber. Lifting the suction hose will help to ensure the
water goes into the pump housing and not out the suction hose. Lay
the hose back on the ground, and reinstall the air cushion chamber
cap.
