MAINTENANCE:
LAMP REPLACEMENT
Step 1 - Remove Guard Assembly
:
1.
Grasp the Guard Assembly as shown. Unscrew (turn
CCW) to remove Guard from Rear Casing and set
aside. Do not touch the Lens - fingerprints on the Lens
surface will attenuate the light beam. Do not remove
the two retaining clips and screws which attach the
Lens and O-ring to the Guard.
Step 2 - Uncover Lamp:
1.
Grasp the Heat Shield Tube as shown and gently screw
inwards (turn CW) until it makes contact with the
inside surface of the Rear Casing.
IMPORTANT:
Stop
turning when the Shield Tube first touches the Rear
Casing - forcing it beyond the “contact point” could
result in damage to Disk and Lamp Socket!
Step 3 - Remove Lamp:
1.
Carefully grasp the exposed edge of the Lamp reflector
and gently pull the Lamp straight out of the socket -
keep Lamp centered in the Shield as you pull.
WARNING:
Do not touch the glass bulb portion of the
halogen Lamp. Oils left by finger contact can cause the
glass to bubble and possibly explode.
2.
Discard the old Lamp.
CAUTION:
To prevent injury
from broken glass, wrap the Lamp in heavy paper or
cardboard, or secure in a container before discarding.
Step 4 - Install New Lamp:
1.
When installing the replacement Lamp, ensure that its
pins align with the socket receptacles, which are
accessible through the opening in the Heat Shield Disk.
Carefully press the pins straight into the receptacles
until the base of the Lamp is firmly seated against the
Disk. If the Lamp pins are properly aligned, the Lamp
will seat easily.
CAUTION:
Do not press hard on Lamp -
it could break and cause injury.
NOTE:
The pin
receptacles are offset at a slight angle. Do not twist the
Lamp when inserting into socket - pins could bend and
damage Lamp and socket.
Replacement Lamp:
Use only USHIO 20MR11 20watt/
12volt. Use of any other lamp may degrade the operation
of the ALU-29CF and/or cause a safety hazard.
