Care and Maintenance

7.1

Maintenance

UNPLUG POWER CORD FROM WALL OUTLET AND DISCONNECT FROM UNIT BEFORE
ANY MAINTENANCE IS ATTEMPTED.

Reflector

Clean the aluminum reflector every four months or as required.

After disconnecting power and allowing the lamp to cool, the reflector is accessed by removing
the chamber cover. Next remove the four screws holding the reflector. Use Isopropyl alcohol and
a clean, soft cloth to clean the reflector.

Lamp and Sockets

Inspect the lamp sockets when installing a new lamp and replace if corroded. Heat generated by
poor connections can reduce lamp life.

Lamp should be replaced as required. It is recommended that the lamp output be monitored
regularly with a radiometer to insure that the product is being completely cured. The Loctite

®

Zeta

®

Meter 7010 (part number 98001) can be used to monitor performance. As an alternative,

regular inspection of the cured product may provide an indirect and less accurate measure of
lamp function. If a radiometer is not used to track lamp life, the lamp should be replaced at least
after every 1,000 hours of operation.

To remove the lamp, first disconnect power from unit and allow lamp to cool. Next remove the
chamber cover by removing the four retaining screws. The reflector assembly is now visible.
Remove the four screws holding the reflector lamp assembly and invert the reflector, set down in
place, being careful not to damage the lamp holders or dent the reflector.

When handling the lamp, cotton gloves or a soft cloth should be used. Do not touch 
the lamp with bare hands or fingers, the oil form your hands will cause the lamp to 
fail prematurely.

Grasp the ends of the lamp, near the socket to remove it. Inspect the new quartz lamp envelope
for cleanliness. If necessary, clean the lamp with isopropyl alcohol and a soft cloth. Insert the
new lamp into the sockets, grasping it only at the ends. Reinstall the reflector and the four
screws. Replace the chamber cover and the four retaining screws.

Work Surface

If the work surface becomes coated with adhesive or cracks, a new work surface pad can be
installed. The part number for the work surface pad is # 985298.
