Installation
1. Check voltage at installation site. It must match the
voltage requirements of the pump. Refer to “Technical
Data” in this manual or the Dataplate attached to the
pump.
2. Attach a hose to the discharge fitting on the pump
using a hose clamp. Hose should have the same
inside diameter as fitting on pump for best operation.
Use the shortest length of hose possible. Check that
hose is free of creases, sharp bends, and other
obstructions that may interfere with the discharge flow
of water.
Note:
In stationary installations the use of a check
valve in the discharge hose is suggested to prevent
water in hose from flowing back into the pump when
it is shut off.
3. Check that screen around bottom of pump is clean.
4. Lower or place pump in water. Make sure pump is
resting on a firm, level surface and will not tip while
operating.
Note:
If pump is being placed on a sandy or soft,
muddy bottom, it may be necessary to suspend it
several inches above bottom to prevent it from pulling
in large amounts of sand and dirt.
5. Connect pump to power supply.
DO NOT
use the power cord to carry, lower, or
suspend pump. The cord cannot support the weight
of the pump. Use a rope tied through pump handle.
WARNING
1.8
Connection to Power Supply
This pump is equipped with a 3-wire cord rated for
outdoor use.
It is recommended that the pump be connected to a
power source equipped with a ground fault interrupt
circuit (GFIC). Circuits protected by a ground fault
interrupt provide added protection against electrical shock.
WARNING
This pump must be grounded to reduce the risk of
electrical shock. Use only 3-wire plugs and connect
pump only into receptacles which are properly
grounded and equipped with a third wire ground.
DO
NOT
use 2-pronged adapters to connect pump to
power source.
1.9
Operation
Check pump after startup to ensure water is flowing
freely from discharge hose.
If debris is collecting around the pump screen, blocking
it, place a large basket screen around pump to hold
debris back. Clean pump screen as often as necessary
to maintain a continuous flow of water.
CAUTION:
DO NOT
let pump run dry. Running pump
dry will cause it to overheat.
Pump capacity is directly proportional to the height of the
discharge hose above the pump. The higher the dis-
charge hose is above the water the less water the pump
will move. The maximum discharge height is listed in the
Technical Data as “Maximum Head”.
CAUTION:
The lower housing of this pump is filled with
oil to lubricate and cool the pump seal. If the seal is
ruptured, this lubricating oil can escape and contaminate
the liquid being pumped.
