It is easier to check rotation before installing the pump.
Switch any two power leads to reverse rotation.
Lower the pump(s) into the wetwell.
Check to insure that the floats will operate freely and not
contact the piping.
OPERATION
Once the piping connections are made and checked you
can run the pumps.
Piggyback Switch Operation – Plug the piggyback
switch into a dedicated grounded outlet and then plug
the pump into the switch. Test the pump by filling the
wetwell until the pump goes On. If the pumps run but
fail to pump, they are probably air locked, drill the relief
holes per the instructions in the Piping Section.
Check the operating range to insure a minimum one
minute run time and that the pump goes Off in the
correct position.
Control Panel Operation – Fill the wetwell with clear water.
Use the pump H-O-A (Hand-Off-Automatic) switches in
Hand to test the pumps. If they operate well in Hand pro-
ceed to test Automatic operation. If the pumps run but
fail to pump, they are probably air locked, drill the relief
holes per the instructions in the Piping Section.
Place Control Panel switch(es) in Automatic position and
thoroughly test the operation of the ON, OFF, and Alarm
floats by filling the wetwell with clear water. Important:
Failure to provide a Neutral from the power supply to a
1Ø, 230 volt Control Panel will not allow the panel control
circuit to operate. The Neutral is necessary to complete
the 115 volt control circuit.
Check voltage and amperage and record the data on the
front of this manual for future reference. Compare the
amperage readings to the pump nameplate maximum
amperage. If higher than nameplate amperage investi-
gate cause. Operating the pump off the curve, i.e. with
too little head or with high or low voltage will increase
amperage. The motor will operate properly with voltage
not more than 10% above or below pump nameplate
ratings. Performance within this range will not necessarily
be the same as the published performance at the exact
rated nameplate frequency and voltage. Correct the
problem before proceeding. Three phase unbalance is
also a possible cause. See Three Phase Power Unbalance
and follow the instructions.
Reset the Alarm circuit, place pump switch(es) in the Au-
tomatic position and Control Switch in ON position. The
system is now ready for automatic operation.
Explain the operation of the pumps, controls and alarms
to the end user. Leave the paperwork with the owner or
at the control panel if in a dry, secure location.
FLOAT SWITCH AND PANEL CHART
The purpose of this chart is to show the required switch
quantities and the function of each switch in a typical
wastewater system. The quantities required vary de-
pending on the switch type, single-action or wide-angle.
Switch quantities also vary by panel type: simplex with
and without alarms, and duplex with alarms.
