1. 機台漏水怎麼防範?
Ans:The leak detector resides in the water drip pan which houses the water manifolds. The pan sits beneath the turbo pump above the turbo molecular pump(TMP) controller. If water is detected in the pan, an alarm will appear indicating that there is a leak, and the main water control valve will close.
1)Locate the fan speed adjustment knob located on the right side of the FFU.
2)For the 3LPM system, set the speed control knob on the FFU to 8.5 and set the switch to the manual position. With the knob set at this position, the average airflow velocity is approximately 80 fpm at the upper boundary of the mini-environment, and approximately 60 fpm at the lower boundary of the mini-environment. See Figure 3 and Figure 4 for mini-environment details.
PS. fpm = ft/min
3)For the 3LPM system, verify that the adjustable louver is set to 50 percent open. See Figure 2. If it is not, perform the next step.
4)Loosen the 6 screws that hold the adjustable louver in place. Adjust all the bottom vents to 50 percent slot open. Tighten the screws after you make the adjustment.
