Troubleshooting (cont.)
It is normal to hear the compressor run for up to 90 seconds after the door is raised. The
compressor is located inside the door and is inflating the door seal.
If the door is fully raised for more than 20 minutes when there is no water in the bath,
the seals will automatically deflate.
It is normal to hear the solenoid valve, located inside the door, open and expel air when
the water level falls below the sensors. The valve is deflating the door seal.
Water coming from the bottom of the door and entering the receptor tray is normal when
it is caused by the bather moving about in the bath when it is completely full. Excessive
splashing will cause water to run over the top of the inflated seals into the receptor tray.
Water dripping into the receptor tray as the seals deflate is normal. Water collects on the
seal during use and falls into the receptor tray when the seals deflate.

adjusting the mounting brackets
outward using the slots.
