(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.

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

tHeSe InStRUctIOnS cOULD ReSULt In SeRI-

eRtY DAMAGe.

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-

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
