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
dam age 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.
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 low est practical number of starts per day. Excessive
cycling accelerates bearing, spline, and pump wear and
con trol contact erosion.
PREINSTALLATION PROCEDURES AND CHECKS
ELECTRICAL SPLICES AND CONNECTIONS
Splices must be waterproof. Make a strong mechanical bond
between the motor leads and the cable to avoid high resistance
at the connection. A poor mechanical con nection, or a poorly
wrapped splice, can cause motor problems and motor failure.
Before connecting the motor to the cable, perform a ground
check to assure that the motor has not been damaged. Attach
one end of an ohmmeter lead to any of the three motor leads
and the other ohmmeter lead to the pump intake bracket. A new
motor must have a resistance of 2 megohms or greater. If not,
contact your dealer. Repeat for all three leads.
