ELECTRICAL WIRING AND CONTROL

SETTINGS – FINAL CHECK LIST

____

1. Does  the  feeder  line  voltage  correspond  to  the  unit

voltage? Check the unit nameplate 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  pres-

sure  switch  needs  to  be  set  for  proper  operation.
Any  subsequent  change  in  system  operating  condi-
tions  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.

WARNING: Electrical shock hazard. Inspect all elec-
trical connections prior to powering the unit. Wiring

connections  must  be  made  by  a  qualified  electrician  in
accordance  with  all  applicable  codes,  ordinances,  and
good practices. FAILURE TO FOLLOW THESE INSTRUC-
TIONS  COULD  RESULT  IN  SERIOUS  PERSONAL
INJURY, DEATH, AND/OR PROPERTY DAMAGE.

WARNING:  Conduit  grounds  are  not  adequate.  A 
separate  ground  wire  must  be  attached  to  the

ground  lug  provided  in  the  enclosure  to  avoid  potential
safety hazards. FAILURE TO FOLLOW THESE INSTRUC-
TIONS  COULD  RESULT  IN  SERIOUS  PERSONAL
INJURY, DEATH, AND/OR PROPERTY DAMAGE.

CAUTION:  Seal  damage  may  occur.  Do  not  run
pumps  dry.  Fill  and  vent  the  pump  volute  prior  to

operation.  FAILURE  TO  FOLLOW  THESE  INSTRUC-
TIONS  COULD  RESULT  IN  PROPERTY  DAMAGE
AND/OR MODERATE PERSONAL INJURY.

Appendix B

WARNING:  Electrical  shock  hazard.  Single  phase 
or  three  phase  AC  power.  Disconnect  and  lockout
