READ AND FOLLOW SAFETY
INSTRUCTIONS!
This is the safety alert symbol. When you see this
symbol on your pump or in this manual, be alert to the
potential for personal injury.
warns about hazards that will cause serious
personal injury, death or major property damage if ignored.
warns about hazards that can cause serious
personal injury, death or major property damage if ignored.
warns about hazards that will or can cause
minor personal injury or property damage if ignored.
The label NOTICE indicates special instructions which are
important but not related to hazards.
Carefully read and follow all safety instructions in this
manual and on pump.
Keep safety labels in good condition.
Replace missing or damaged safety labels.
GENERAL CONSIDERATIONS
Before installing your submersible turbine pump, review
the following checklist.
Be sure the well is clear 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.
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.
Air entrained in the water reduces performance and will
damage the pump.
Your pump is designed to provide maximum efficiency
under specific capacity and head conditions. Do not oper-
ate it beyond specified limits.
System controls and pump must match. 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.
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
control contact erosion.
