WARNING
The bare shaft booster can generate excessive noise. Methods to reduce
the noise levels by installing inlet and outlet silencers will be required. Even
with inlet and outlet silencers, hearing protection will be required.
WARNING
Customers are warned to provide adequate protection, warning and safety
equipment necessary to protect personnel against hazards in the installation
and operation of this equipment in the system or facility.
WARNING
Table 1 states the maximum operating speed in RPM (rotations per minute)
and maximum temperature. Do not exceed these limits. The installation of
the booster shall take these critical operating parameters into account and
adequate control features implemented.
WARNING
Upon completion of the installation, and before applying power, rotate the
drive shaft by hand. It must move freely. If it does not, look for uneven
mounting, piping strain, excessive belt tension or coupling misalignment or
any other cause of binding. If booster is removed and still does not move
freely, check inside the booster housing for foreign material.
NOTE
Remove the protective covers from the shaft and inspect for damage.
Carefully check to ensure that no transit damage has been sustained. If damage has occurred from
shipment a claim must be led with the carrier immediately; preserve the shipping container for inspection
by the carrier.
NOTE
In the event that your unit sustains damage while being shipped to your
facility, do not return it to the factory without rst obtaining shipping
instructions from us.
Protective covers and plugs should not be removed until the connection is being made. Mount the booster
on a at, level surface. We recommend a baseplate that is a rigid, solidly supported, and structurally
sound. Shim under the legs where necessary so that each leg of the booster supports an equal share of the
booster weight. This is necessary to prevent eventual twisting of the booster. Make sure feet rest evenly on
the mounting surface before fastening down. Twisting or cramping the booster in mounting will cause rotor
contact and binding during operation, resulting in a condition called “soft foot”. (See the Soft Foot section
of this manual for further details and preventative measures.)
A unit that is factory mounted on a base, should not require the above adjustments. However, since
the assembly can become twisted in shipping or installation, checking for soft foot should be done after
installation of the base. Shims may be needed for alignment. Loosen the foot hold-down screws to check
foot contact with the mounting surface. The base should be mounted on a solid foundation or heavy ooring,
using shims as necessary at bolting points to prevent warping the assembly. (Also refer to the Foundation
section.)
Transmission of small operating vibrations to a support structure may be objectionable in some cases. Use
of vibration isolators or vibration absorbing materials can be effective in overcoming this problem. To avoid
casing distortion, the treatment used should be applied under the common motor/booster base or mounting
plate, rather than directly under the feet alone.
