## Discrepancy

CIDS CAUTION LIGHT ILLUMINATED.  MAINT TEXT:  LEFT EMERGENCY SLIDE PRESSURE LOW.  UPON BOTTLE INSPECTION FOUND APU PRESSURE LEAK BLOWING DIRECTLY ON THE LEFT EMERGENCY OVERWING SLIDE INFLATION BOTTLE, HEATING IT UP TO THE POINT THAT THE GREEN SCALE WAS PEGGED TO THE HIGH PRESSURE SIDE.  REPLACED 2 EA PRESSURE SEALS ON APU DUCT.  LEAK CHECK GOOD.  BOTTLE PRESSURE NORMAL.
