Xylem IM201 CentriBoost Fixed Speed Pumping Package - Manual (Page 4)


(Cu) wire rated for at least 75° C may be used for the
power connections. Refer to the input current as listed
on the motor nameplate when sizing wire.

Refer to the NPE pump Installation, Operation and Main-
tenance manual for specific details unique to the pump.
The following field connection diagrams should be re-
viewed prior to unit installation and operation.

INSTAllATION INSTRUCTIONS
Locate the pumping unit for ease of inspection, mainte-
nance, and service.
Place the unit preferably on a concrete floor or base.
Level the steel base, on which the pumps are mounted, in
both directions by placing steel shims between the base
and the anchor bolts.
HEAVY LOAD, MAY DROP IF NOT
LIFTED PROPERLY. DO NOT LIFT
THE ENTIRE UNIT BY THE MOTOR EYEBOLTS.
LIFT THE UNIT WITH SLINGS PLACED UNDER
THE UNIT BASE RAILS. FAILURe tO FOLLOW

A well-leveled and secured unit will result in quiet opera-
tion as well as longevity of service.
See drawing 1MBD0 (Simplex) or 1MBD0 (Duplex) in
Section 6 for general piping requirements.
Eccentric increasers can be used in the suction line when
increasing the pipe size. The straight side of eccentric
reducers should be installed with the flat side on top to
eliminate air pockets. Support the suction and discharge
lines independently by the use of pipe hangers or an-
chors. Do not attempt to spring the suction and dis-
charge lines into position. It is recommended that a three
() valve by-pass between the suction and discharge be
installed at this time. See drawing 1MBD0 or 1MBD0
for location of valves.
IMPORtAnt: Do not install and operate Goulds pumps
in closed systems unless the system is constructed with
properly sized safety devices and control devices. Such
devices include the use of properly sized and located
pressure relief valves, compression tanks, pressure
controls, temperature controls and flow controls as ap-
propriate. The CentriBoost includes a high temperatures
cut out. If the system does not include the other devices,
consult the responsible engineer or architect before mak-
ing pumps operational.
THE HEATING OF WATER AND
OTHER FLUIDS CAUSES VOLUMET-
RIC EXPANSION. THE ASSOCIATED FORCES MAY
CAUSE FAILURE OF SYSTEM COMPONENTS AND
RELEASE OF HIGH TEMPERATURE FLUIDS. THIS
WILL BE PREVENTED BY INSTALLING PROPERLY
SIZED AND LOCATED PRESSURE RELIEF VALVES
AND COMPRESSION TANKS. FAILURe tO FOL-

IMPORtAnt: Unless the piping to which the vibra-
tion eliminators are connected to are properly anchored
to the floor, the benefits may not be fully realized. See
drawing 1MBD0 (Simplex) or 1MBD0 (Duplex).
ELECTRICAL SHOCK HAZARD.
INSPECT ALL ELECTRICAL CONNEC-
TIONS PRIOR TO POWERING THE UNIT. WIRING
CONNECTIONS MUST BE MADE BY A QUALIFIED
ELECTRICIAN IN ACCORDANCE WITH ALL APPLI-
CABLE CODES, ORDINANCES, AND GOOD PRAC-
TICES. FAILURe tO FOLLOW tHeSe InStRUc-
tIOnS cOULD ReSULt In SeRIOUS PeRSOnAL

The power supply required for the unit is either 0/1/60
or 08, 0, 60//60 with a dedicated ground wire.
Single phase motors have internal overload protection
and three phase motors have external overload protec-
tion in the control panel.
On single phase units the disconnecting means and short
circuit protection are to be supplied and mounted by
others. Three phase units have disconnecting means and
fuses for short circuit protection in the control panel.
For units installed with an optional tank, the tank must
be installed to the top connection of the discharge cross
for simplex units and the discharge manifold for duplex
units (see 1MBD0 or 1MBD0). Precharge the tank per
the tank specific IOM.
For units installed with an optional low suction pressure
switch, the switch, which typically ships loose, must be
piped to the inlet ¼" tap on the check valve for simplex
units or on of the ¼" tap on the suction manifold for du-
plex units (see 1MBD0 or 1MBD0). See section .10
for instructions on setting the switch.
CONDUIT GROUNDS ARE NOT AD-
EQUATE. A SEPARATE GROUND WIRE
MUST BE ATTACHED TO THE GROUND LUG PRO-
VIDED IN THE ENCLOSURE TO AVOID POTENTIAL
SAFETY HAZARDS. FAILURe tO FOLLOW tHeSe
