 Change Set Temperature at Heating Status
When the machine is in heating status, press the MODE key till the number on
Temperature Display flashes. Press the Adjust key to change the number to the
desired temperature (the machine will keep at heating status during the setup
process). After the setup finishes, the machine will run towards the set temperature
automatically without turning on HEAT key again.
4. If the unit is turned off when it is in operation and the power is not removed, it will
restore the status and setup of the last operation when it is turned on again.
5. Turn on the power and start heating at ultrasonic standby status (ultrasonic is not
turned on), the machine will activate ultrasonic device for 5 seconds every 2
minutes to balance solution temperature. The function is not available at degassing
standby status.
6. When ultrasonic or degassing finishes, heating stops simultaneously and the machine
turns to standby status. To maintain the temperature, simply turn on the machine
and then turn on HEAT key. The machine will restore the set temperature of the last
operation and go to heating status.
NOTE:
You may require an exact/constant temperature for your application. Please note that
ultrasonics may continue to heat the solution beyond your set temperature, even
though the heater has cycled off and the "Heat On" light is still light. If this happens,
turn the cleaner off and allow the solution to cool down. For a fast cool down, replace
some of the warm solution with cold solution.
The optimal temperature of the heating solution is 55 ~ 60°C. When the temperature
goes up to 65 ~ 80°C, ultrasonic internal resistance would increase by 10~20% and
the power would reduce by 24~34%.
