OPERATING THE UNIT
All materials relating to safety should be reviewed prior to operating. The chamber and
lamp power supply should be properly installed. Assure that all cables are properly
installed, the lamp has been installed and the Chamber door is closed.
1. Refer to 7215 figures 5-7 on page 9. Push the Chamber Power On button located at the
lower right side of the Chamber. The amber light on the Chamber Power switch block
should light. See figure 5.
2. Push the Control Power On button located on the Lamp Power Supply. The amber light on
Control Power Switch Block should light. See figure 6.
3. Push the Lamp Power On button located on the Lamp Power Supply. The amber light on
Lamp Power Switch Block should light. See figure 6.
4. Wait for the Cycle Start Lamp/Button to illuminate. (Located at the center right side of the
Chamber.) See figure 5.
5. Set Cycle timer for desired cure time. (Cycle timer setting instructions in figure 7.)
6. Open Chamber door and adjust shelf for desired intensity. The maximum ultraviolet intensity
is available at the top of the chamber and the minimum at the bottom shelf position. If you are
not sure about the proper shelf setting utilize a Loctite
®
ZETA
®
7010 Puck Radiometer. Using
the ZETA
®
7010, a measurement of intensity can be obtained at any shelf position. This
measurement can be used to determine proper part placement and day to day process
repeatability. The ZETA
®
7010 can be placed in the oven, the Chamber door closed, then
when the cycle start button is pushed, the ZETA
®
7010 will detect and record the ultraviolet
light when the shutter opens. After the shutter closes the ZETA
®
7010 can be removed from
the chamber and intensity or total energy read on the digital display. Contact your Loctite
representative at 1-800-LOCTITE for the ZETA
®
7010 Puck Radiometer part number 98001.
Parts should be placed near the center of the shelf. If you have no means of measuring
intensity, it is recommended that test samples are placed near the bottom of the chamber
then moved up if the intensity is not sufficient. Do not place parts so high as to interfere with
the shutter.
7. Close the Chamber door. Refer to the illustration of Chamber Door Knob figure 8 on page 10.
Push the Cycle Start button. The part can be observed through the window located above the
Chamber door. If it becomes necessary to end cure cycle, push the CYCLE STOP BUTTON
and the shutter will close.
8. At the end of the cycle remove parts from Chamber.
9. To shut down the system, first push the Lamp Power Off, then the Control Power Off, wait
three minutes then turn Chamber Power off. The three minute time period allows the fans to
provide a lamp cooling period.
