The LS780B 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.
• CLEANING THE STANDARD SENSOR HOUSING:
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, clean the housing
using soap and water ONLY.
NOTE: Use of solvents or cleaners to clean the
housing will leave a residue that may adversely affect
the performance of your unit.
• PATENTED EVAPORATOR 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
LOWPRESSURE shop air or by hand ONLY. DO NOT
attempt to clean this housing by any other means. If
the sensor housing remains contaminated, simply
replace it.
