FIELD CONNECTION DIAGRAMS
1.8.1
Refer to the pump Installation, Operation, and Main-
tenance Manual for specific details unique to the
pump.
1.8.2
Refer to the flow sensor/transmitter Installation,
Operation, and Maintenance Manual for specific
details unique to the flow sensor/transmitter.
SECTION 2 – INSTALLATION
2.0
LOCATION
2.1
Locate the pumping unit for ease of inspection, main-
tenance and service.
DANGER: Heavy load, may drop if not lifted prop-
erly. 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 serious personal injury, death, and/or property
damage.
2.2
INSTALLATION
This unit is built to give you years of service; install it
properly and provide a suitable foundation. A base of
concrete weighing 2
recommended. (Check the shipping ticket for the unit
weight.) Tie the concrete pad in with the finished
floor. Use foundation bolts and larger pipe sleeves to
give room for final bolt location.
2.3
LEVELING
Place the unit on its concrete foundation, supporting
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.
2.4
UNIT SUPPORT AND LOCATION
The Bell & Gossett Series 70E/70M Pressure Booster
should be installed where there will be sufficient room
for future inspection and service. If the unit is to be
located near a noise sensitive area, consult a sound
specialist. Special precautions should be taken to
avoid sound and vibration transmission.
2.5
PIPING
2.5.1
Important. Do not install and operate ITT Bell &
Gossett 70E/70M Pressure Booster in a closed sys-
tem unless the system is constructed with properly
sized devices and control devices. Such devices
include the use of properly sized and located pres-
sure relief valves, compression tanks, pressure con-
trols, temperature controls and flow controls as
appropriate. If the system does not include these
devices, consult the responsible engineer or architect
before making pumps operational.
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 by prevented by install-
ing properly sized and located pressure relief valves and
compression tanks. Failure to follow these instructions
could result in serious property damage and serious
personal injury or death.
2.5.2
Make all necessay system piping connections. Be
aware that connecting dissimilar metals to the headers
can lead to corrosion damage due to galvanic corro-

The following field connection diagrams should be
reviewed prior to unit installation and operation.

sion. The rate of corrosion is dependant on various
factors some of which are: the potential between the
dissimilar metals, electrolyte conductivity, geometry
and areas of the metals. Dielectric connections are
recommended between dissimilar metals at the
header connection. Be sure to eliminate any pipe
strain on the unit. Support all pipes independently by
use of pipe hangers near the unit. DO NOT ATTEMPT
TO FORCE THE SUCTION OR DISCHARGE LINES
INTO POSITION. Refer to assembly drawing for cus-
tomer piping connections.
2.5.3
Eccentric increasers can be used in the suction lines
when increasing the pipe size, with straight sides of
increaser on top to eliminate air pockets.
2.5.4
As a rule, ordinary wire or band hangers are not ade-
quate to maintain alignment. It is very important to
provide a strong, rigid support for the suction line. A
saddle hanger is recommended.
2.5.5
For critical installations, equipment for absorbing
expansion and vibration should be installed in the
inlet and outlet connections of the unit.
2.5.6
After hydrotesting, drain plugs are removed, to facili-
tate system drainage, placed in a cloth bag and
secured to the unit. Drain plugs shall be reinstalled
prior to filling the system with fluid. Inspect all unit
piping connections. Joints may also become loose
during transit due to vibration and shock. All joints
are to be checked for tightness. Flanged joints should
be checked for proper torque of all flange bolts prior
to filling the system with fluid.
CAUTION: Failure to reinstall drain plugs, check all
joints for tighteness and flange bolts for proper
torque could result in leaks and/or flooding. Failure to
follow these instructions could result in property
damage and or moderate personal injury.
2.5.7
On an open system with a suction lift, use a foot
valve of equal or greater area than the pump suction
piping. Prevent clogging by using a strainer at the
suction inlet next to the foot valve. The strainer
should have an area three times that of the suction
pipe. Provisions must be made to prime the pump
suction piping on start up. Do not start the pump
unless all suction piping is full of water.
2.5.8
A thermal relief valve (B&G Part #S51260) is installed
on the discharge header to prevent potentially dan-
gerous thermal buildup in the package. This valve
acts as a safety device and it should never be re-
moved or tampered with. It is factory set to open and
discharge when the water temperature in the dis-
charge header exceeds 125˚F. The
of this valve must be piped to a floor drain.
2.6
LUBRICATION
Before starting, all pumps and motors should be
checked for proper lubrication.
