V. SERVICING
THE FOLLOWING SERVICE SECTION OUTLINES MAINTENANCE PROCEDURES.
ALL SERVICING SHOULD BE PERFORMED BY QUALIFIED SERVICE PERSONNEL.
The front cover containing the filter window should only be opened for lamp replacement or
maintenance. Observe all warnings and cautions provided in this Operator’s Manual before
initiating any service procedures. Refer all other electrical or mechanical problems to quali-
fied NOCTURN technical personnel
.
WARNING:
Do not subject the lamp or fixture to extreme mechanical shock or
rough handling that may damage the lamp or internal components.
DANGER:
Disconnect the main power cord prior to attempting any service to
the lamp or fixture.
Lamp Replacement
The lamp should be replaced when it has reached its maximum rated life of 1,000 hours.
See section VI (page 20) for replacement lamp part numbers.
For safety reasons, NOCTURN recommends that soft cotton gloves be worn when han-
dling the lamps during the following LAMP REPLACEMENT procedure.
1) Push the power switch/ circuit breaker to the OFF position.
2) Unplug the fixture. Wait a minimum of 10 minutes for the lamp to cool before proceed-
ing if the fixture was operating.
3) Open the front cover by pushing the lock tab of the latch forward, then lift the catch link
up and forward. Carefully lower the front cover until it supports itself.
4) Grasp one end of the lamp and push in axially towards the socket, (compress the
socket). DO NOT PROCEED IF THE LAMP IS STILL HOT.
5) While one end is compressing the socket, rotate the opposite end towards the front of
the fixture.
6) Completely remove the lamp and properly dispose of it.
7) To install a new lamp, hold one end of the lamp and engage the opposite end into the
socket. Compress the socket with the lamp and swing the end that is being held until it
fully engages the other socket contact.
8) Visually ensure the lamp is fully engaged into both sockets and can rotate axially be-
tween the contacts with ease.
9) Rotate the lamp so the fill tube pinch (bump) is orientated to the top. This will help with
the lamp ignition sequence and overall life.
10) Clean the entire lamp with a swab soaked in isopropyl alcohol to remove any con-
taminants or oils and completely dry with a lint-free cloth.
11) Close and secure the front cover with the latch.
12) Reset the lamp hour meter (See page 12).
