2.2.2 Grout
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. To hold wedges or shims in
place, allow the grout to flow around them and
beneath the entire length of the base flange.
2.2.3 Closed System Safety Measures
Important: Do not install and operate the Bell &
Gossett Technologic 5500 Variable Primary pump
and valve controller in a closed system unless the
system is constructed with properly sized safety 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 appropriate. If the sys-
tem does not include these devices, consult the
responsible engineer or architect before making
pumps operational.
2.2.4 Eccentric Increasers
Eccentric increasers can be used in the suction lines
when increasing the pipe size, with straight sides of
the increaser on top to eliminate air pockets.
2.2.5 Pipe Support
Be sure to eliminate any pipe strain on the unit.
Support the suction and discharge pipes indepen-
dently by use of pipe hangers near the unit. Line up
the vertical and horizontal piping so that the bolt
holes of the flanges match. DO NOT ATTEMPT TO
SPRING THE SUCTION OR DISCHARGE LINES
INTO POSITION. As a rule, ordinary wire or band
hangers are not adequate to maintain alignment. It is
very important to provide a strong, rigid support for
the suction line. A saddle hanger is recommended.
2.2.6 Expansion and Vibration Absorbtion
For critical installations, equipment for absorbing
expansion and vibration should be installed in the
inlet and outlet connections of the unit.
2.2.7 Lubrication
Before starting, all pumps and motors should be
checked for proper lubrication.
2.3 Putting the Unit into Service
2.3.1 Pump Rotation, 3 Phase Motors Only
It will be necessary to check for proper rotation for all
pumps in both variable speed and bypass. Run each
pump in AUTO and then in BYPASS, if so equipped,
and note the rotation in each.
If both rotations (AFD and bypass) are wrong, ex-
change the wiring on two motor phases. If the rota-
tion is incorrect in the AFD mode, but it is correct in
the bypass mode, exchange the wiring on two of the
AFD output phases.
If the rotation is correct in the AFD mode, but it is
incorrect in the bypass mode, exchange the wiring on
two of the bypass input phases.
NOTE: Changing phase at AFD input does not change
output phasing.
2.3.2 Joint Check
While the unit may be hydro tested at the factory to
internal quality standards, there may be some joints
that are not pressure tested. Some joints may have
been loosened, to allow for draining of the system,
and not retightened. Thus, some joints may be loose
due to system drainage or shocks during the ship-
ping process. All flanged joints are to be checked for
tightness and proper torque of the flange bolts prior
to filling the system with fluid.
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 INSTRUC -
TIONS CAN RESULT IN SERIOUS PROPERTY DAMAGE
AND SERIOUS PERSONAL INJURY OR DEATH.
CAUTION: Seal Damage may occur. Do not run
pumps dry. Fill and vent the pump volute prior to
operation. FAILURE TO FOLLOW THESE INSTRUC -
TIONS COULD RESULT IN PROPERTY DAMAGE
AND/OR MODERATE PERSONAL INJURY.
WARNING: Rotating shafts can catch loose clothing.
Do not operate the pump without all guards in place.
FAILURE TO FOLLOW THESE INSTRUCTIONS COULD
RESULT IN SERIOUS PERSONAL INJURY, DEATH,
AND/OR PROPERTY DAMAGE.
WARNING: Failure to check all joints for tightness
and all flange bolts for proper torque could result in
leaks and/or flooding. FAILURE TO FOLLOW THESE
INSTRUCTIONS COULD RESULT IN SERIOUS PER-
SONAL INJURY, DEATH, AND/OR PROPERTY DAMAGE.
DANGER: High voltage 3 phase power can kill. Dis-
connect and lockout power prior to servicing unit.
FAILURE TO FOLLOW THESE INSTRUCTIONS WILL
RESULT IN SERIOUS PERSONAL INJURY, DEATH,
AND/OR PROPERTY DAMAGE.
