Original instructions
Mounting Support Requirements
You must provide vibration isolators, vibration mounting pads, and/or a roof curb
support for proper mounting of the blower. Vibration isolators or vibration
mounting pads are available from many sources such as a local industrial supply
company. Labconco recommends supporting the blower with 5/16" diameter
mounting hardware.
Electrical Power Requirements
Please refer to the wiring diagrams in Appendix C. The exterior blower wiring
should be terminated at the junction box located inside the blower housing. The
outside blower weather cover is removed to access the junction box. The MSB
blower is wired according to the specific voltage and terminations on the motor
and blower model. Locate the specific wiring voltage for your blower motor on
the instruction manual cover and in the charts in Chapter 4: Performance Data and
Safety Precautions. All MSB blowers operate at a maximum of 10 full load amps
for 115V and 6 full load amps for 230V.
Controls Wiring Requirements
Please refer to the wiring diagrams in Appendix C. The MSB comes with the
Intelli-Sense MSB Control Box, controls cable, power inlet cable, 3-position
switch, and 3-position switch label. The power for the MSB Control Box comes
from the light circuit on the fume hood. The controls wiring for the MSB requires
a fume hood modification to add the control cable from the 3-position switch/label.
A shielded cable from the roof blower junction box must be run to the MSB
Control Box per the wiring diagram and wiring detail in Appendix C. If needed,
refer to the diagram in Appendix E that further depicts the controls needed for a
typical laboratory with individual Intelli-Sense blowers.
Space Requirements
The dimensions for the different models are shown in Appendix B: Blower
Dimensions.
