		no clear path, (e.g. the wick is twisted causing a
		blockage), refer to the manual section on replacing the
		wick.
		If there appears to be excessive water dripping from the
		instrument after inlet removal, flooding may have
		occurred. Disconnect the water fill bottle at the quick
		disconnect and allow the instrument to run for a few
		hours without the wick cartridge installed. This will dry
		the instrument.
