OPERATOR SERVICING
The following instructions are intended for limited servicing of the lamp. Do not perform
any servicing that is not covered in these instructions. Return the lamp to the factory for
maintenance not covered in this section.
HOUSING AND FILTER MAINTENANCE
CAUTION: Always shut off the switch on the ballast and unplug the ballast from the power
outlet before performing any maintenance or servicing. Allow the lamp to cool before
handling.
Clean the lamp and ballast housings with water and a mild detergent and wipe dry. Periodically
clean the filter with a glass cleaner and a soft cloth.
FILTER REPLACEMENT
The lamp is shipped with a 2F958 filter lens. This may be used with either the
BLE-35RA spot bulb or the BLE-35RAF flood bulb. The 2F350 filter lens may be ordered with
a BLE-35RA spot bulb (only) to produce a more diffused spot beam
that is not as wide as the flood beam.
1. Peel the silicone-rubber filter holder from around the circumference of the lamp housing. The
filter will remain inside the filter holder.
2. Press the existing filter out of the filter holder.
3. Press the new filter gently but firmly into the filter holder.
4. Reattach the filter holder by pressing it around the circumference of the lamp housing with the
heel of your hand. Be sure the groove in the filter holder seats over the rim of the housing.

BULB REPLACEMENT
Use only a Spectroline UV bulb/reflector assembly. Using any other bulb may damage the
unit and will void the warranty. The lamp is shipped with a BLE-35RA spot bulb/reflector
assembly as standard. The lamp may be ordered with a BLE-35RAF flood bulb/reflector
assembly.
1. Remove the filter holder.
2. Insert the bulb/reflector tool in the two holes in the old bulb/reflector, rotate counterclockwise
and pull.
3. Hold the new bulb/reflector by its protective cover while inserting it into the socket with a
clockwise quarter-turn bayonet action. Firm pressure is needed to overcome the spring in the
socket. Pop off the black fasteners and remove the protective cover.
4. Reattach the filter holder.
UV INTENSITY VERIFICATION
To ensure that your MAXIMA™ ML-3500 is operating at the required UV intensity, it should
be checked periodically. The AccuMAX
TM
wavelength UV-A/VIS sensor detector to accurately measure ultraviolet irradiance or visible
light. The AccuMAX XR-1000 digital readout unit with the XS-365 UV sensor or the Spectroline
DM-365XA digital readout unit are also recommended for accurate UV-A measurement. The
meters are specially designed to measure the UV irradiance from 320–400nm with a peak at
365nm.
