Occupational Noise Exposure
Burr King vibratory tubs produce levels of noise consistent with their intended purposes. The level
and spectral content of noise produced is dependent on the tub size, the degree that the bowl is
maintained in proper operating condition, the abrasive/media and accessories used, the specific
application, use or not of the optional lid, and the surrounding environment. Noise levels produced
by various Burr King vibratory tubs, as measured at the Burr King factory, range from 81 to 93 decibels. Product
operators and persons in the immediate product vicinity should be protected from excessive noise does levels as
prescribed in OSHA regulation 29, part 1910.95 titled “Occupational Noise Exposure”.
Avoid electrocution hazards . This vibratory is not NEMA 4 or NEMA 4X rated. They must
not be used in a manner that allows fluids to enter the unit base, power cord, on/off switch, or
electrical plug. This machine must be installed with a GFCI outlet to minimize the risk of electric
shock or electrocution. If your machine is configured for 208-240 volts you should install a GFCI
circuit in your electrical distribution panel.
Electrical requirements:
CAUTION: Only qualified Electricians should perform electrical installation, adjustments, maintenance, or
modifications to this equipment. Failure to observe this caution may create a safety hazard.
CAUTION: Install this equipment in accordance with local electrical codes and regulations. Failure to do so may
create a safety hazard.

Unless specified at purchase three phase machines are not equipped with a magnetic starter or power cord. Three
phase machines should be connected to the mains supply via a magnetic starter. Failure to use a magnetic starter
may create a /fire hazard, and/or void the motor warranty.
NOTE: All 3 phase units purchased with an integrated process timer come from the factory with an integrated
magnetic starter. If you are unsure about the installation of your machine or its electrical configuration please
consult the Burr King factory. The integrated 3 phase magnetic starter incorporates 120VAC-button control through the
use of a step down transformer. The step down transformer also provides 120 VAC power for the integrated timer and the
fluid pump.
A special note about motor rotation. Electric motors will operate CW or CCW depending on how the motor is
wired (in the case of tree phase motors how the incoming power is phased). The machine drive shaft must rotate
CCW when view from the discharge chute end of the machine. If the shaft rotates CW the media will not move
properly and vibratory processing time will be significantly increased. If the shaft operates CW reverse the motor
rotation. For three phase machines simply reverse any two incoming feed lines. For single-phase motors see the
motor label plate which will usually direct the reversal of two wires with in the motor conduit box.
