6. An apparent leak shall be verified at least once as follows:
a) Blow shop air into the area of the suspected leak, if necessary, and 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) First move the probe to fresh air and reset. Then hold the probe tips as close as possible to
the indicated leaksource and slowly move around it until the leak is confirmed.

7. Leak testing of the evaporator core while in the air conditioning module shall be accomplished
by turning the air conditioning blower on high for a period of 15 seconds minimum, shutting it
off, then waiting for the refrigerant to accumulate in the case for 10 minutes.
After such time, 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 condi-
tioning case to the evaporator, such as the heater or vent duct. If the detector alarms, a leak
apparently has been found.
BATTERY MAINTENANCE
Charging Batteries
CAUTION: Batteries should only be charged in temperatures between 50ºF and
104ºF (10ºC - 40ºC). 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 indicator shows only the Red LED, the batteries must be re-charged.
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).
