This manual contains important information for the safe use of
this product. Read completely and do not throw away.
Reasonable care and safe methods should be practiced. Check
local codes and requirements before installation.
UNPACKING PUMP
LIFTING HAZARD. Unassisted lifting of pump can
cause injury. Mechanical assistance required.
DO NOT lift pump by power cord.
When unpacking unit, check for damage. Claims for damage must
be made at the receiving end through the delivery carrier. Damage
cannot be processed from the factory.
RISK OF FIRE OR EXPLOSION. Do not smoke or
use sparkable electrical devices or flames in a septic (gaseous)
or possible septic sump. Do not pump flammable liquids with
this pump.
PUMPS IN STORAGE OR NOT OPERATING
Pumps with silicon/carbide seals must have impellers manually
rotated (6 revolutions) after setting non-operational for 3 months
or longer and prior to electrical start-up.
SEAL FAILURE PROBES
HAZARDOUS DUTY RATED PUMPS:
All submersible pumps have two factory installed moisture
detectors (seal failure probes). They should have a resistance
of around 330K ohms for the series circuit in the seal chamber.
Under normal operating conditions, the circuit remains around
330K ohms. If the circuit shows open, the circuit is not complete
indicating a broken wire, corroded wire, or loose connection.
If the lower seal leaks and moisture enters this chamber, the
moisture will settle to the bottom of the chamber and will
complete (significantly less than 330K ohms) the circuit between
the moisture detectors.
NON-HAZARDOUS DUTY RATED PUMPS:
For all non-hazardous duty rated pumps the resistance(ohm)
readings between the seal probe wires should be open in
normal operating conditions. A lower resistance indicates water
intrusion.
This circuit must be connected to a sensing unit and signaling
device. This is supplied in a manufacturer built control panel.
Failure to install such a device negates all warranties.
HEAT SENSORS
All motors in this family have heat sensors on or embedded in the
motor winding to detect excessive heat. This prevents damage to
the motor. If sensor trips due to excessive winding temperature,
the starter in the panel interrupts power to the pump.
The
sensors are set to trip at 130°C.
Failure to install such circuitry would negate FM approvals and all
warranties.
POWER CORDS
DO NOT modify the cord. When wiring to a system
control, connect the pump ground lead to the system ground.
The power cord and heat sensor seal failure cord are potted into
the cord cap. The cords must not be spliced.
Each cable has a green lead. This is the ground wire and must be
grounded properly per NEC and/or local codes. Cords should be
inspected for abnormal wear and replaced accordingly.
