Pump is permanently lubricated. No oiling or greasing is
required in normal service.
NOTICE: Do not allow pump to run in a dry sump. It will
void the warranty and may damage the pump.
Hazardous voltage. Can shock, burn, or
cause death. Before servicing pump, disconnect electrical
power to pump and control switch.
After removing basin cover and necessary discharge piping,
lift pump out of basin.
Risk of electrical shock. Can burn or kill.
Do not lift pump by power cord. See “Cord Lift Warning”
above.
Place pump in an area where it can be cleaned thoroughly.
Remove all scale and deposits on pump.
Submerge pump in disinfectant (chlorox or chlorine) for at
least one hour before disassembling pump.
The pump motor housing contains a special lubricating oil.
Keep oil clean and free of water at all times.
NOTICE: Whenever motor cover is being removed for
service, remove oil and replace with new oil at reassembly.
Use only oil listed in parts list (Part No. U197-8A). When
filling with new oil, DO NOT overfill. To allow room for
expansion, oil level with cold motor should be about 1/4"
(6 mm) above top of motor assembly.
Impeller, Seal, and Capacitor Replacement
– 700E/700EH/700S Series
Risk of electrical shock. Disconnect
electrical power before doing any service work on pump!
Refer to assembly drawings on Page 4.
Disassembly
1. Unscrew hex-head cap screws, remove motor assembly
from volute and set it on its side in a clean area.
2. Remove oil plug. Turn pump upside down to drain oil.
3. Hold impeller; remove impeller nut and washer.
4. Unscrew impeller (turn counter-clockwise) for cleaning.
Risk of electric shock. Before touching
capacitor, discharge it by shorting the terminals
together with an amber handled screwdriver.
5. Loosen cord nut and gently pull cord assembly out from
motor cover. Disconnect wires from cord set (wires and
connector are color coded for reassembly).
6. Unfasten socket head screws holding motor cover to seal
plate and remove motor cover.
7. If replacing capacitor, remove wires from capacitor.
Remove capacitor.
1. Attempting to lift or support pump by
power cord can damage cord and cord
connections.
2. Cord may pull apart, exposing bare wires
with possibility of fire or electrical shock.
3. Lifting or supporting pump by power
cord will void warranty.
4. Use lifting ring or handle on top of pump
for all lifting/lowering of pump.
Disconnect power to pump before doing
any work on pump or attempting to
remove pump from sump.
Risk of electrical shock.
Can burn or kill.
Do not lift pump by
power cord.
WARNING
Overloads - Single Phase
In single-phase units, an automatic overload protector in the
motor will protect motor from burning out due to over-
heating/overloading. When motor cools down, protector
automatically resets and start motor.
If overload trips frequently, check for cause. It could be a
stuck impeller, wrong/low voltage, or electrical failure in
motor. If an electrical failure in the motor is suspected, have
it serviced by a competent repairman.
Control Panel Overload Adjustment
- 3 Phase
NOTICE: Control panel not provided with pump. See con-
trol panel installation and operating instructions before
adjusting overload setting.
For pumps with a nameplate service factor of 1.0, set
overload protective device to nameplate full load current.
For pumps with a nameplate service factor of 1.15 or higher,
set overload protective device to 1.09 times the nameplate
full load current.
Size overload protective device so that trip current is 115%
of final setting as selected above.
