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 7216 figures 11-13 on page 22. 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 11.
2. Flip Power Switch to “1” on Power Supply. See figure 12.
3. Push the Lamp Button located on the Power Supply. See figure 12.
4. Wait for the Cycle Start Lamp/Button to illuminate. (Located at the center right side of
the Chamber.) See figure 11.
5. Set the Cycle timer for the desired cure time. (Cycle Timer setting instructions in figure 13.)
6. Open the Chamber Door and adjust the 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 unsure 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 the Chamber Door Knob figure 14 on
page 23. Push the Cycle Start Button. The part can be observed through the window located
above the Chamber door. If it becomes necessary to end the cure cycle, push the CYCLE
STOP BUTTON and the shutter will close.
8. At the end of the cycle remove the parts from Chamber.
9. To shut down the system, first push the Lamp Off, then the Power Switch to “O” on Power
Supply (figure 12), wait three minutes then turn Chamber Power off. The three minute time
period allows the fans to provide a lamp cooling period.
