WIRING
Plug the unit into an 120 VAC outlet and allow it to run continuously. The ballast is factory

the ballast and set for the correct voltage. (Figure A) Connect in accordance with local wiring codes.
MAINTENANCE
This maintenance schedule is only a guideline, determined by average conditions. Actual
conditions will dictate the frequency of cleaning and/or replacement of lamps. Do not touch the
glass portion of the lamp with bare hands because oils from the hands can cause “hot spots”
which reduce lamp life. Handle either by the porcelain caps or use a soft cloth. If you
accidentally touch a lamp, wipe it off, using a soft cloth dampened with rubbing alcohol.

using a 11/32 size nut driver.
