The tabs on each side of the mounting collar have Installation teeth that latch into the ridges on the sides of the panel controller. Each tooth is staggered at a different bezel retention collar depth from the front so that only one of the tabs, on each side, is locked onto the ridges at a time. gasket Note: There is a graduated measurement difference between case the upper and lower half of the display to the panel. In order to meet the seal requirements mentioned above, ensure that the

Returning the Controller to its Case 1. Ensure that the orientation of the controller is correct and slide it back into the housing. Note: The controller is keyed so if it feels that it will not slide back in do not force it. Check the orientation again and reinsert after correcting. 2. Using your thumbs push on either side of the con- troller until both latches click. Chemical Compatibility This product is compatible with acids, weak alkalis, alcohols, gamma radiation and ultraviolet radia
