GENERAL CONSIDERATIONS
Before installing your submersible turbine pump, review the
following:
Clear well of sand and abrasive material before installing
pump. Abrasive materials in the water cause component
wear and reduce pump capacity and discharge pressure.
Never use the pump to develop or clean the well. Permanent
pump damage can result within the first few hours of
operation.
Align well casing. If the well casing is suspected of being
crooked, check it with a gauge of identical length and
diameter as the pump and motor with two lengths of pipe
attached. Serious dam age can result if the pump becomes
lodged in a crooked casing.
Be sure the well can supply a high-capacity turbine
pump. The well should be deep enough to cover the pump
unit with water, even at extreme pumping rates. Typically, the
pump should be submerged 10 to 20 feet below the lowest
water level and at least 5 feet above the bottom of the well.
Prime pump. Air entrained in the water reduces performance
and will dam age the pump.
NOTICE: Do not inter change controls with other models.
Serious damage can result to the unit if pump and controls
do not match.
Motor control systems and pump units are repairable in the
field. To avoid serious damage to the unit, use only parts
obtained from authorized dealers/suppliers. System controls
and pump must match.
Average number of starts per day will influence motor and
control component life (starters, relays, capacitors, etc).
Select pump size, tank size and control components for
lowest practical number of starts per day. Excessive cycling
accelerates bearing, spline, and pump wear and con trol
contact erosion.
Your pump is designed to provide maximum efficiency under
specific capacity and head conditions. Do not oper ate it
beyond specified limits.
