Bell & Gossett S14141B 70X Multiple Pump Pressure Booster Systems - Manual (Page 5)

1.5 GROUND CONNECTIONS
1.5.1 A grounding terminal is provided for a dedicated
ground wire connection. All provisions of the
National Electrical Code and local codes must be
followed.
1.6 POWER WIRING
1.6.1 Power wire types and sizes must be selected
based upon conformance with the National
Electrical Code and all local codes and restric-
tions. In addition, only copper (Cu) wire rated for
75°C (minimum) may be used for the power con-
nections. Refer to the input current as listed on
the nameplate on the enclosure door when sizing
wire.
1.7 FIELD CONNECTION DIAGRAMS
1.7.1 Actual equipment manufacturers/models installed
are system specific. Refer to specific manufacturers
Installation, Operation & Maintenance Manuals for
details unique to each component. The following
instruction manual categories are supplied with
the system (if applicable):
Pump
Technologic 500X Pump Controller
(IOM part #176U7761)
Thermal Relief Valve
PRV
Check Valve
1.7.2 The following field connection diagrams
should be reviewed prior to unit installation
and operation.
SECTION 2 - INSTALLATION
2.1 LOCATION
2.1.1 Locate the pumping system in a clean, well
ventilated and properly drained location. It is rec-
ommended that the location selected facilitates
ease of inspection, maintenance and service.
Outside installations require protection from freezing.
2.2 FOUNDATION
2.2.1 This unit is built to give you years of service;
install it properly and provide a suitable foundation.
A base of concrete weighing 2-1/2 times the
weight of the unit is recommended. (Check the
shipping ticket for unit weight.) Tie the concrete
pad in with the finished floor. Foundation bolts of
proper size and pipe sleeve should be set in con-
crete. The pipe sleeve will allow some flexibility in
bolt alignment to match the holes in the base plate.
Allow sufficient bolt length for grout, shims, base
plate, nuts and washers.
2.3 LEVELING
2.3.1 Place the unit on its concrete foundation, support-
ing it with steel wedges or shims totaling 1" in
thickness. These wedges or shims should be put
on both sides of each anchor bolt to provide a
means of leveling the base. After leveling is com-
plete, evenly and firmly tighten the foundation nuts.
Do not fully tighten the bolts until after grouting.
2.4 GROUTING
2.4.1 After the frame has been leveled and securely
bolted to the pad, a good grade of grout should be
installed beneath the base. A suggested mixture
for grout is: one part Portland Cement and two or
three parts plain, sharp sand mixed with water
until it will pour easily. Commercial grout mixtures
with suspended iron particles are available. Wet the
concrete base before pouring grout. Build a strong
form around the foundation to contain grout. Allow
the grout to flow around wedges & shims and
beneath the entire length of the base flange. Allow
the grout to set, usually 48 hours after pouring,
before fully tightening the foundation bolts.
2.5 PIPING CONNECTIONS
2.5.1 Important. Do not install and operate a Bell &
Gossett Pressure Booster in a closed system
unless the system is equipped with properly sized
control devices. Such devices include the use of
properly sized and located pressure relief valves,
compression tanks, pressure control, temperature
controls and flow controls as appropriate. If the
system does not include these devices, consult
the responsible engineer or architect before mak-
ing pumps operational.
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 INSTRUCTIONS COULD
RESULT IN SERIOUS PERSONAL INJURY, DEATH,
AND/OR PROPERTY DAMAGE.

DANGER: Heavy load, may drop if not lifted properly.
Do not lift the entire unit by component eyebolts.
FAILURE TO FOLLOW THESE INSTRUCTIONS WILL
RESULT IN SERIOUS PERSONAL INJURY, DEATH,
AND/OR PROPERTY DAMAGE.
DANGER: The heating of water and other fluids
causes volumetric expansion. The associated forces
may cause failure of system components and releases of
high temperature fluids. This will be prevented by installing
properly sized and located pressure relief valves and com-
pression tanks.
FAILURE TO FOLLOW THESE INSTRUCTIONS CAN
RESULT IN SERIOUS PROPERTY DAMAGE AND SERI-
OUS PERSONAL INJURY OR DEATH.
CAUTION: Extreme temperatures are to be avoided
(below 32°F and above 110°F).
FAILURE TO FOLLOW THESE INSTRUCTIONS COULD
RESULT IN PROPERTY DAMAGE AND/OR MODERATE
PERSONAL INJURY.
