GASKET REPLACEMENT
Four gaskets seal the gauge from moisture, dirt, and debris.
However if the gauge has been out in extremely wet weather, high
humidity or if the gauge was used in the cold and stored in a warm
building, condensation may form inside the gauge. If this happens,
remove the top shell and allow the gauge to dry. Use a hair dryer
(on low heat) if necessary to remove any built-up moisture.
If moisture continues to be a problem or debris is present inside the
gauge base, the gaskets may need replacing.
To replace the control panel gasket, remove the four screws and take
the panel off the gauge top shell. Use care in removing the panel and
ribbon cable. Gently peel the old gasket from the panel and top shell
and replace with new gaskets. Replace the connectors and the
control panel.
To replace the top shell gaskets, remove the screws that hold the top
shell to the gauge base. Gently peel the gaskets away from the top
shell and gauge base and replace. Tighten top shell screws to
6 in-lb.
If replacing the post gasket slide it up over the source rod. A light
coating of talcum powder on the inside of the new post gasket will
aid in re-assembly.
