Trouble Shooting Chart; Motor Not Running - ITT Bell & Gossett SC03 Manuel D'instruction

4.3. Check to insure all piping connections are
tight. The pipes should be supported by
fastening to floor joists or wall. This will
prevent the pump from moving in the sump.
If it moves the switch could get stuck and
either keep the pump running or not let it
turn on.
4.4. The power to the outlet should be Off at
this point. The dedicated outlet should sup-
ply power only to the pump.
4.5. Our sump pumps have either a single power
cord for pumps with built-in switches or
two power cords for pumps with piggyback
switches:
Built-In/Single Cord - plug the single power
cord into a dedicated power outlet.
Piggyback/Two Power Cords - insert the pig-
gyback switch male plug into a dedicated
power outlet. You then plug the standard
male pump plug into the back, female side,
of the piggyback switch plug.
4.6. Fasten the power cords to the discharge
pipes using tie wraps or electrical tape. Coil
and store any excess power cord outside the
sump.
5. OPERATION 5. OPERATION
5.1. Turn the power On at the breaker panel
and/or the disconnect switch.
5.2. Fill the basin with water and observe where
the pump turns On and Off. It should go On
well before the water overflows the top of
the sump. The pump should go Off before
the water goes below the pump suction. The
On-Off cycle on models with wide-angle
float switches is adjustable. Adjustment is
made by changing the tether length between
the switch body and the switch tether (pivot)
point. The tether length cannot be less than
3" – 3.5". Tethers less than 3" may not allow
the float to drop down enough to turn off.
See "Installation Data".
5.3. Install a cover on the sump
WARNING
basin if there is a danger
of debris, children, or pets falling into the
basin. See Basin "Style" in Section 2.3.
6. SEASONAL SERVICE / MAINTENANCE
6. SEASONAL SERVICE / MAINTENANCE
6.1. If your sump pump only operates seasonally
and then sits idle for months it is recom-
4
mended that you test the pump before your
rainy season begins. Fill the sump with water
and check for debris and proper switch
operation. Remove any debris which could
clog the suction strainer or jam the switch.
Insure that the switch operates freely and
does not hit the sump wall or hang-up on
piping or power cords.

7.1. Your pump supplier has a full line of basins,
covers, high water alarms, and battery back-
up pump systems available to complete your
system. We also sell simplex and duplex
pump control panels. A duplex system is
recommended when the inflow is constant
and the pumps run almost continuously. The
duplex system provides a back-up pump in
the event the primary pump fails.

Extreme caution should be exercised when ser-
vicing electrical devices. Fatal injuries could re-
sult from electrical shock. Always disconnect the
electrical power from the device being serviced
unless it is necessary for the work being done.
