Bell & Gossett S14367B Technologic Constant Speed Pump Controller - Manual (Page 7)

Technologic ® Constant Speed Pump Controller Installation, Operation and Maintenance Manual 7
General
The unit should be unloaded and handled by quali-
fied personnel. A pumping package that includes this
panel may be top heavy due to the position of the
motors. Lift the unit with slings placed under the unit
base rails. Be sure not to load the lifting mechanism
beyond its rated limits. Use the motor eyebolts to sta-
bilize the unit while lifting to prevent overturning.
DANGER:
Heavy load, may drop if
not lifted properly. Do not load cables,
chains or hoists beyond their rated limits.
FAILURE TO FOLLOW THESE INSTRUC-
TIONS COULD RESULT IN SERIOUS
PERSONAL INJURY, DEATH AND/OR
PROPERTY DAMAGE.
1.5 Foundation
A concrete base weighing at least 2.5 times the weight
of the pumping package is 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.
1.6 Leveling
Place the pumping package on its concrete founda-
tion, 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.
1.7 Location
Install the pumping package appropriately for ease of
inspection, maintenance and service. Observe local
electrical codes concerning control panel spacing.
1.8 Piping
Be sure to eliminate any pipe strain on the pumping
package. Support all pipes independently by use of
pipe hangers near the unit. Ordinary wire or band
hangers are not adequate to maintain alignment. It is
very important to provide a strong, rigid support for
the suction and discharge lines. A saddle hanger is
recommended. Do not attempt to force the suction
or discharge lines into position. Refer to the assembly
drawing for customer piping connections.
Inspect all unit piping connections. Joints may also
become loose during transit due to vibration and
shock. All joints should be checked for tightness.
Flanged joints should be checked for proper torque
of all flange bolts prior to filling the system with
fluid.
Eccentric increasers may be used in the suction lines
when increasing the pipe size, with the straight sides
of the increaser on top to eliminate air pockets.
For critical installations, equipment for absorbing
expansion and vibration should be installed in the
inlet and outlet connections of the unit.
Drain plugs are placed in a cloth bag and secured to
the unit prior to shipping from the factory. Reinstall
the drain plugs prior to filling the system with fluid.
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.
A thermal relief valve is installed on the discharge
header to prevent potentially dangerous thermal
buildup in the package. This valve acts as a safety
device and it should never be removed or tampered
with. It is factory set to open and discharge when the
water temperature in the discharge header exceeds
125°F. The 3/8” NPT opening of this valve must be
piped to a floor drain.
Before starting, all pumps and motors should be
checked for proper lubrication.
1.9 Temperature and Ventilation
The operating temperature range for this unit is 0 to
50°C. The relative should be kept between 10% and
90% non-condensing. The unit should not be operat-
ed outside these extremes.
1.10 Incoming Power and Ground Wiring
A qualified electrician should bring incoming power
and ground wiring to the disconnect switch. If holes
are drilled in the control panel, be sure to not con-
taminate electrical components with metal filings. A
grounding terminal is provided next to the discon-
nect switch for an incoming ground wire connection.
Wire types and sizes must be selected according to
the National Electrical Code and all local codes and
restrictions. Refer to the input current and voltage as
listed on the nameplate on the enclosure door when
sizing the power wires. Only copper (Cu) wire rated
for 75°C (minimum) may be used for the power con-
nections. The voltage tolerance is +10/-5% and
phase to phase voltage must not have an imbalance
greater than 5 VAC.
WARNING: Prevent electrical shocks.
Disconnect the incoming power supply to
the control panel before beginning installation.
FAILURE TO FOLLOW THESE INSTRUC-
TIONS MAY RESULT IN DEATH OR
PROPERTY DAMAGE.
WARNING: Conduit grounds are not
adequate. A separate ground wire must be
attached to the ground lug provided in the enclo-
sure to avoid potential safety hazards. FAILURE
TO FOLLOW THESE INSTRUCTIONS
COULD RESULT IN SERIOUS PERSONAL
INJURY, DEATH AND/OR PROPERTY
DAMAGE.
