CHOOSING A LOCATION:
Be sure that the unit is installed on a level table. Remember, the LS-Jr must be located in an explosion-proof area. Consult NFPA
guidelines for specific details and requirements on ventilation, structures, lighting and other electricals, earth-grounding, and size of
explosion-proof area
ELECTRICAL CONNECTIONS
The LS-Jr requires a 220 volt, 1 phase, 5 amp electrical service with ground. Electrical connections must be performed by a quali-
fied electrician and in accordance with the National Electric Code for Class 1, Division 1, Group D installations. Use only explosion-
proof electrical components.
After installation, check the unit’s ground. The resistance between the LS-Jr and earth-ground must be less than one ohm (1
Ω). If it
is not, a separate ground must be installed from the unit to earth for prevention of static electricity sparks. Use the grounding block
provided on the right side of the LS-Jr.
