Bell & Gossett 70M Multiple Pump & Control Pressure Booster Systems - Manual (Page 22)

APPENDIX A
SYSTEM PIPING AND UNIT
INSTALLATION – FINAL CHECK LIST
____ 1. Is the unit base properly leveled, grouted and
secured?
____ 2. Are all lubrication points properly lubricated?
____ 3. Is the outlet side of the high temperature regulating
valve connected to the drain with tubing or pipe size
3 /
8
" or greater?
____ 4. Are the shut-off valves to the suction and discharge
transmitters open?
____ 5. Is the shut-off valve to the pump suction open?
____ 6. Is the shut-off valve on the discharge line open?
____ 7. Is the bypass valve, if used, closed? This valve may
be left open if a check valve is installed in series
with it.
____ 8. Are the stop cocks for the check feature on the PRV
open? They must never be completely closed during
normal operation. Throttle cock if check slamming is
noted.
____ 9. Is the piping properly supported so as to prevent
strains on unit?
____ 10. Is the system, including the pumps and PRV’s,
purged of debris and air?
____ 11. Are the bleed valves at the high temperature valve
header open?
____ 12. Are the pump and motor shafts properly aligned?
____ 13. Is the pump rotation correct?
APPENDIX B
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. Are the fuses correctly sized? They must not exceed
1.75 times the full load current of the motor. Usual
sizing is 1.15 to 1.5 times the full load current.
____ 4. Is the unit properly grounded?
____ 5. 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.
