LAMPING
Before lamping or re-lamping, make sure that power is turned
off to the fixture.
To gain access to the lamp compartment, loosen 10 captive
screws (Item 12) in the removable cover (Item 23). (Cover
nearest 1/2 in. NPSI hole). DO NOT REMOVE BARRIER
(Item 27). DO NOT REMOVE THE FIXED COVER (Item 22)
WHICH HAS THE LAMP SOCKET ATTACHED TO IT.
Screw lamp into socket. Reinstall removable cover (Item 23)
and tighten 10 screws (Item 12) to 15 in-lbs. The fixture can
be mounted and electric power connected.
1. Operate fixture ONLY with PROPER lamp. The internal
ballast in each fixture is designed to accommodate a specific
wattage lamp. See LAMP RECOMMENDATIONS.
2. If the lamp fails, replace lamp or disconnect primary
power to fixture within two weeks at the most. Otherwise,
permanent damage to electrical components may result from
high voltage pulses unique to High Pressure Sodium circuits.
3. Use protective gloves and safety eyeglasses when
replacing lamps.
If outer glass bulb is broken, turn off lamp and replace it
promptly to avoid exposure to ultraviolet energy. Even with
lamp outer glass enclosure broken, the arc tube may
continue to fire.
