Place the Break Away Fitting (BAF) in position. Temporarily
secure the guide rails in the upper mounting brackets and
locate the base on the bottom of the wet well. Level the base
with grout and/or shims. Install the intermediate support
brackets, if required. Make sure the rails are in a true vertical
position so the pump will clear the access opening and will
slide freely down the rails into place on the discharge
stationary fitting. Once the rails are in proper alignment, bolt
the base into the floor of the station and connect the
discharge pipe to the elbow.
Connect the movable portion and other supplied fittings of
the BAF onto the pump and lower into wet well. See the
Break Away Fitting manual for more information.
C-3) Liquid Level Controls:
The level controls are to be supported by a mounting bracket
that is attached to the sump wall, cover or junction box. Cord
grips are used to hold the cords in place on the mounting
bracket. The control level can be changed by loosening the
grip and adjusting the cord length as per the plans and
specifications. Be certain that the level controls cannot hang
up or foul in it’s swing and that the pump is completely
submerged when the level control is in the "Off" mode.
Remove any build-up foreign material (grease, rust, etc.)
from floats so adequate buoyancy is maintained.
C-4) Electrical Connections:
C-4.1) Power/Control Cable:
The cord assembly mounted to the pump must not be
modified in any way except for shortening to a specific
application. Any splice between the pump and the control
panel must be made in accordance with the National Electric
Code or Canadian Electric Code and all applicable state,
province and local electric codes. It is recommended that a
junction box, if used, be mounted outside the sump or be of
at least Nema 4 (EEMAC-4) construction if located within the
wet well.
DO NOT USE THE CABLE TO LIFT PUMP.
C-4.2) Overload Protection :
Single & Three Phase-
These units are connected in series
with the stator windings. One thermostat is required per
pump. The thermostat sees full pump amperage. They are
current and temperature sensitive.
The type of in-winding overload protector used operates on
the combined effect of temperature and current. This means
that the overload protector will trip out and shut the pump off
if the windings become too hot, or the load current passing
through them becomes too high. It will then automatically
reset and restart the pump after the motor cools to a safe
temperature. In the event of an overload, the source of this
condition should be determined and rectified immediately.
DO NOT LET THE PUMP CYCLE OR RUN IF AN
OVERLOAD CONDITION OCCURS !
C-4.3) Moisture Sensor: (Double Seal Pumps)
A normally open (N/O) detector designed to indicate
moisture present in the lower shaft seal. It is recommended
that this detector be connected in series to an alarm device
or the motor starter coil to alert the operator that a moisture
detect has occurred. In the event of a moisture detect, check
the individual moisture sensor probe leads for continuity, (
∞
resistance = no moisture ) and the junction box/control box
for moisture content. The above situations may induce a
false signal in the moisture detecting circuit. If none of the
above test prove conclusive, the pump(s) should be pulled
and the source of the failure identified and repaired.
IF A MOISTURE DETECT HAS OCCURRED SCHEDULE
MAINTENANCE AS SOON AS POSSIBLE.
C-4.4) Wire Size:
Consult a qualified electrician for proper wire size if
additional power cable is required. See table for electrical
information.
SECTION: D START-UP OPERATION
D-1) Check Voltage and Phase:
Before operating pump, compare the voltage and phase
information stamped on the pump identification plate to the
available power.
D-2) Check Pump Rotation:
Before putting pump into service for the first time, the
motor rotation must be checked. Improper motor rotation
can result in poor pump performance and can damage the
motor and/or pump.
1. To check the rotation, suspend the pump freely,
momentarily apply power and observe the "kickback".
"Kickback" should always be in a counter-clockwise
direction as viewed from the top of the pump motor
housing.
2. If pump is in an accessible location, lay pump on it’s
side, stand clear and apply power to pump at nameplate
voltage. Looking into volute, impeller should be rotating
counterclockwise. If it is running in opposite direction,
interchange two leads (red, white or black).
3. If unit has been installed in tank, install pressure
gauge in discharge line. Add water to tank if required
and close discharge line. Start pump by actuating
controls, loosen pressure gauge, bleed air from
discharge line. Retighten pressure gauge and note the
pressure reading. Interchange two pump motor leads
(red, white, or black). This will reverse the motor
rotation. Start pump again. Bleed air from discharge
line. Recheck the pressure gauge reading.
Direction of rotation giving the highest pressure gauge
reading is the proper rotation (
NOTE: pressure gauge
reading will vary approximately 2 to 3 P.S.I. from correct
to incorrect. Note the noise level when unit is pumping.
