Installation
Note: For intake and discharge hose locations, see FIGURE 1 on page 5.
Note: If power cords must be extended, only use no less than UL approved, 18 Gauge wire.
Do not extend the wires more than 50 feet.
1. Install the pump on a rigid, level platform above the water level. This platform must provide
a solid, level surface that is capable of supporting the weight of the pump, and attached
piping filled with water. Never allow the pump to become immersed in water.
2. The level of the intake port should not be more than 12-15 feet above the water. Pumping
efficiency falls off as the height above the water level increases.
3. Keep the vertical lift that the pump must move water before discharge at a minimum. Vertical
delivery above a few feet will degrade pump efficiency.
4. The intake port must have a screen
(not included) attached to prevent
introduction of debris into the pump. At
the end of the discharge pipe, either
purchase a pre-made screen to fit, or
wrap loose screen and secure with
wire.
5. Lay out the intake and discharge pipes
with as few turns as possible to pre-
vent air pockets within the lines. Air
pockets interfere with pressure switch
performance.
6. Intake and discharge pipes must have
a minimum of 1” to 1-1/4” diameter. Systems with larger vertical components should have
larger diameter piping. Keep in mind that the maximum vertical lift (total vertical distance
from the inlet screen to the discharge outlet) is 140 feet.
7. For your protection, the power outlet used should have a Ground Fault Circuit Interrupter
(GFCI). Have it installed by a qualified electrician. Keep the power line safely away from
water.
8. The inlet and discharge lines should not be wedged or stressed in a way that puts strain
on the pump. Do not support the pump with the inlet and discharge lines.
9. This is a self starting pump that uses a pressure switch. Once the power cord is connected,
the pump can start at any time. Do not handle or perform maintenance on the pump if
the power cord is plugged in.
