Push-Button And Window Housing Flamepaths - Ametek 241CE II Operator's Manual

6-26 | Model 241CE II Hydrocarbon Dewpoint Analyzer

Push-Button and Window Housing Flamepaths

The push-buttons and their holes in the Window Housing (on the User
Interface, Figure 6-3) are subject to very low rates of wear if they are used
under reasonably clean conditions. However, if the analyzer is exposed to
excessive dust, dirt, or other abrasive conditions, it is possible that the de-
bris may eventually enlarge the flamepath gap between the push-buttons
and their holes in the Window Housing.
The push-buttons are constructed of aluminum with a blue anodized
finish. The Window Housing is constructed of aluminum with a black an-
odized finish. Periodically, examine the push-buttons and the holes in the
Window Housing for any visible signs of wear, such as color loss on the
cylindrical portion of the push-buttons. If the push-buttons show signs
of wear or become damaged, contact your AMETEK Service Representa-
tive.
!
If the push-buttons become stuck, do not attempt to dislodge them
using pliers or any other tools. Do not use any force to dislodge them;
CAUTION
doing so may scratch, bend, or otherwise damage the push-buttons,
causing damage to their flamepaths. If this happens, they must be
replaced.
