Keystone KSTAP10PINV User Manual page 26

· When the water level of the bottom tray reaches a prede-
termined level, the unit beeps 8 times, the digital display
area shows "P1" . At this time the air conditioning/dehum-
idification process will immediately stop. However, the fan
motor will continue to operate(this is normal). Carefully
move the unit to a drain location, remove the bottom drain
plug and let the water drain away. Reinstall the bottom drain
plug and restart the machine until the "P1" symbol disappears.
If the error repeats, call for service.
NOTE: Be sure to reinstall the bottom drain plug firmly to
prevent leakage before using the unit.
