batteRY Maintenance
The unit is equipped with a standard nickel–metal–hydride (Ni-MH) battery pack . Refer
to the Replacement Parts section for details .
charging batteries
caution: charge batteries in temperatures ranging between 50°f and 104°f
(10°c - 40°c). charging batteries outside this temperature range may cause
permanent damage to the batteries.
Whenever the Constant Power Indicator LED appears red, and/or the True Battery
Voltage test shows only the red LED, the batteries must be recharged .
To recharge the batteries:
1 . Plug the charging unit into an appropriate wall outlet, and connect the charger jack
to the unit (see Fig . 3, page 5) .
Maintenance
6 . Verify an apparent leak as follows:
a) Blow shop air into the area of the suspected leak . Repeat the check of the area . In
cases of very large leaks, blowing out the area with shop air often helps locate the
exact position of the leak .
b) Move the probe to fresh air and reset . Then hold the probe tip as close as possible
to the indicated leak source, and slowly move around it until the leak is confirmed .

7 . Leak test the evaporator core in the air conditioning module by turning the air
conditioning blower on high for a period of 15 seconds minimum, shutting it off, and
then waiting for 10 minutes for the refrigerant to accumulate in the case .
Then insert the leak detector probe into the blower resistor block or condensation
drain hole, if no water is present, or into the closest opening in the heating/
ventilation air conditioning case to the evaporator, such as the heater or vent duct . If
the detector alarms, a leak apparently has been found .
