4.0 FINAL CHECK LIST
A. SYSTEM PIPING AND UNIT INSTALLATION
_____ 1. Is the unit base properly leveled and
secured?
_____ 2. Are all lubrication points properly lubricated?
_____ 3. Is the shut-off valve to the pump suction
open?
_____ 4. Is the shut-off valve on the discharge line
open?
_____ 5. Is the bypass valve, if used, closed?
_____ 6. Is the piping properly supported to prevent
strains on unit?
_____ 7. Is the system, including the pumps, purged
of debris and air?
B. ELECTRICAL WIRING AND CONTROL SETTINGS
_____ 1. Does the feeder line voltage correspond to
the unit voltage? Check the unit name-
plate or motor terminal connection.
_____ 2. Are the feeder wires correctly sized for the
load?
_____ 3. Have all the power terminals in the control
panel been checked for tightness? This is
imperative since stranded wires tend to "flow"
and become loose after initial installation.
_____ 4. Are the pressure controls correctly set?
The pressure switch(es) need to be set for
proper operation. Any subsequent change
in system operating conditions may require
resetting the controls. For best results,
use compressed air and a continuity meter
(across the switch) to reset the controls.
The legend plate on the control indicates
approximate readings only, therefore,
should be used with caution.
5.0 TROUBLESHOOTING
5.1 Pump will not operate:
1) Check incoming power
2) Check power fuses. Replace if blown.
3) Check transformer fuses. Replace if blown.
4) Check to see that control voltage is 120 volt.
5) Check motor overload. Reset if tripped.
6) Momentarily turn HOA switch to HAND position
and back to OFF. Does starter pull in? If starter
doesn’t pull into go to next step. If it does pull in
go to step 10.
7) Turn HOA switch to HAND position. Check volt
age across terminals for coil in starter. If voltage
is present and the starter is not pulled in, the coil
is defective and must be replaced. If voltage isn’t
present go to step 8.
8) With HOA still in HAND, check voltage between
HOT side of starter coil and the neutral (white)
wire. 120 volts should be measured. If voltage is
measured go to step 9.
9) With HOA still in HAND, check voltage between
the hot side of coil & neutral (white wire) for over
load block. 120 volts should be measured. If volt
age is measured replace the overload block. If no
voltage is present contact local B&G rep to ser-
vice control circuit.
10) With starter pulled in, check voltage at bottom of
overload block. Voltage should be the same as
the incoming power. If no voltage is present,
replace the starter. If voltage is present, contact
electrician to check the leads & motor.
CAUTION: SEAL DAMAGE MAY OCCUR. DO NOT
RUN PUMPS DRY. FILL AND VENT THE PUMP
VOLUTE PRIOR TO OPERATION.
FAILURE TO FOLLOW THESE INSTRUCTIONS COULD
RESULT IN PROPERTY DAMAGE AND/OR MODERATE
PERSONAL INJURY.
DANGER: Troubleshooting live control panels ex-
poses personnel to hazardous voltages. Electrical
troubleshooting must only be done by a qualified electrician.
FAILURE TO FOLLOW THESE INSTRUCTIONS WILL
RESULT IN SERIOUS PERSONAL INJURY, DEATH,
AND/OR PROPERTY DAMAGE.
WARNING: ELECTRICAL SHOCK HAZARD. IN-
SPECT ALL ELECTRICAL CONNECTIONS PRIOR TO
POWERING THE UNIT. WIRING CONNECTIONS MUST
BE MADE BY A QUALIFIED ELECTRICIAN IN ACCOR-
DANCE WITH ALL APPLICABLE CODES, ORDINANCES,
AND GOOD PRACTICES.
FAILURE TO FOLLOW THESE INSTRUCTIONS COULD
RESULT IN SERIOUS PERSONAL INJURY, DEATH,

WARNING: CONDUIT GROUNDS ARE NOT ADE-
QUATE. A SEPARATE GROUND WIRE MUST BE
ATTACHED TO THE GROUND LUG PROVIDED IN THE
ENCLOSURE TO AVOID POTENTIAL SAFETY HAZARDS.
FAILURE TO FOLLOW THESE INSTRUCTIONS COULD
RESULT IN SERIOUS PERSONAL INJURY, DEATH,
AND/OR PROPERTY DAMAGE.
