MAXIMA™ ML-3500 Series

Micro Discharge Light (MDL) UV-A Lamps

INTRODUCTION

The MAXIMA™ ML-3500 series ultra-high intensity UV lamps feature micro discharge light
(MDL) technology to make all inspections easier, safer and more reliable. The MAXIMA
series lamps are available in three line-voltage models: ML-3500S, with a spot bulb;

ML-3500D, with a spot bulb and a diffusing lter; and ML-3500FL, with a ood bulb for a

wider range. All “M” model MAXIMA lamps operate in both alternating (AC) or direct current

(DC). Each model, ML-3500MS (spot), ML-3500MD (diffusing lter) and ML-3500MFL
(ood) includes a 12-volt, 7 amp/hr rechargeable battery that will operate the lamp for two

hours and a battery charger and carrying case. Each comes equipped with a detachable
AC cord for the country of shipment (120V, 230V, 240V, or 100V).

Ultraviolet radiation emitted from this product. Avoid exposure. ALWAYS WEAR
PROTECTIVE CLOTHING. EXPOSURE MAY CAUSE PREMATURE AGING OF THE
SKIN AND CANCER. ALWAYS WEAR PROTECTIVE EYEWEAR; FAILURE TO DO
SO MAY RESULT IN SEVERE BURNS OR LONG TERM INJURY TO EYE. Never
look directly into the lamp. Exposure can cause eye and skin allergy and allergic
reactions. Medications or cosmetics may increase your sensitivity to ultraviolet
radiation. Consult physician before operating this product if you are using
medications or have a history of skin problems or believe yourself especially
sensitive to sunlight.

FOR PROFESSIONAL EXAMINATION USE ONLY

IMPORTANT SAFETY INSTRUCTIONS

1. Read all instructions.

2. Care must be taken, as burns can occur from touching hot parts.

3. Do not operate the lamp with a damaged cord or if the lamp has been damaged.

4. Wear UV-absorbing protective eyewear (such as the UVS-30 glasses provided) when
operating this or any UV lamp.

5. The filter lens will become hot during use. Never operate the lamp with the UV filter lens
removed.

6. Never use this equipment in any manner not specified in these instructions because the
protection provided by the equipment may be impaired.

NOTE: Due to the ultra-high UV-A intensity produced by this lamp, subject
(penetrants, metals, plastics) fluorescence may fade after a period of exposure.
Therefore, this lamp should not be left shining on any one area for an extended
period.

DANGER

ML-3500S AC OPERATION

1. Connect the plug to a power source that complies with the electrical requirements

specified on the lamp’s label. For best performance and durability, the power source

should be regulated, surge free and noise free. In those regions where mains may
experience fluctuations greater than ± 10%, an overvoltage protection device is
available.

2. Press ON the BLACK ballast rocker switch.

FOR AC OPERATION

1. Align the top notch of the 7-pin plug on the AC cord to the notch in the ballast outlet;
turn the locking ring to the right over the plug to secure.

2. Press ON the BLACK ballast rocker switch.

3. Press ON the RED Inverter rocker switch.

FOR DC OPERATION

1. Connect the 12-volt plug to the Spectroline® BP-12A 12-volt battery pack or to a suitable
DC supply. The BP-12A must be fully charged before using! Refer to the BP-12A
operating instructions for full information.

2. Insert the plug into the receptacle on the battery pack.

3. Align the top notch of the 7-pin plug on the DC cord to the notch in the ballast outlet;
turn the locking ring to the right over the plug to secure.

4. Press ON the BLACK ballast rocker switch.

5. Press ON the RED Inverter rocker switch.

NOTE: The BP-12A battery pack includes a 12-volt battery, 120V/60Hz-charger, the
BP-12A/F has a 230V/50Hz charger, the BP-12A/FA has a 240V/50Hz charger and the
BP-12A/J has a 100V/50-60Hz charger. All battery packs include a nylon carrying case.

IMPORTANT: Disconnect lamp cord plug from battery pack when the unit is not in use.

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 BLE­35RAF 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

XRP-3000 radiometer/photometer kit uses a
dual-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.

For more information about these units, please contact the Customer Service Department
at Spectronics Corporation. In the U.S. and Canada, call toll-free 1-800-274-8888. Outside
the U.S. and Canada, call 516-333-4840.
