Tips for avoiding sensor contamination
● Inspect fitting for signs of oil before connecting
the 69086 vacuum gauge sensor.
● Keep the sensor vertical when possible.
● Connect the gauge directly to the system,
away from the pump.
● Isolate the pump from the system (and the
gauge) with a valve before turning the pump
off. This is very important when the gauge is
mounted near the pump.

Coin Cell Battery
If the unit is not maintaining the correct time and
date, follow the instructions above to remove the
main battery pack and expose the coin cell battery
through an access hole in the floor of the battery
compartment. Using a tool such as a small screw-
driver, deflect the battery to the side until a corner
of the battery springs up slightly. It may be lifted
out of the battery socket at this point. Reverse this
procedure to install the fresh battery.

care must be taken to observe any ways that
an electrical shock hazard could develop.
Example: Wet or humid conditions, along with
a damaged thermocouple or vacuum sensor,
could allow an electrical path across the instru-
