OPERATING TIPS
MAINTENANCE
Windy Conditions:
Do not attempt to find a leak in windy areas.
Even very large leaks may be impossible to find as the escaping
gas is quickly dissipated into the atmosphere. If necessary,
fabricate a gas trap using aluminum foil around joints or fittings
or otherwise shield the search area from the wind.
Recommended Sensitivity Setting:
Start searching for leaks
using the LO sensitivity range to detect and repair the biggest
leaks first. Switch to the HI sensitivity setting if no leaks are
found using the LO setting.
Leak Verification:
If a suspected leak is indicated, verify several
times by moving the sensor away from the leak area, allow-
ing the alarm to clear and then back to the suspected leak. If
the instrument indicates a leak three consecutive times, you
have found a leak.
The LS780C LEAK-SEEKER
®
is designed to require a minimal
amount of field maintenance. Regular cleaning of the sensor
housing air vents, replacement of the Ion-Pump
®
sensor and
changing the batteries are the only maintenance needs.
Battery:
Replace with “AA” alkaline batteries only.
Note: Do not use rechargeable batteries.
Changing the Ion-Pump
®
Sensor:
Eventually, the
Ion-Pump
®
sensor will need to be replaced. This condition is
usually indicated by abnormal or erratic performance when
the instrument is in the lowest sensitivity range. Install the
new sensor as indicated in
Figure-1
(turn the unit OFF before
attempting to change the sensor). CPS recommends that
you change the Ion-Pump
®
sensor at the beginning of every
AC & R season and always have a spare sensor available for
replacement in the field.
Patented Vapor Filter:
Ensure that the sensor housing inlet and
outlet air vents are clean and free of materials that may block
the air from circulating through the Ion-Pump
®
sensor. If the
vents become dirty and clogged remove the housing from the
probe and remove the Ion-Pump
®
sensor (turn the unit OFF
before removing the housing). Next, attempt to remove any
contaminants using low pressure shop air or by hand
ONLY
