2.14 ZoneAire® Sleep Surface Slow Leak—Error Code 2-1
When isolating the fault to one component in the pneumatic subsystem, ensure
that all cables and air hoses are connected properly. Check the coupling and all
tubing for signs of damage.
CAUTION:
To prevent component damage, ensure that your hands are clean, and
handle the P.C. boards by their edges only.
CAUTION:
When working with electronics, wear an appropriate static strap .
Equipment damage can occur.

common source of leaks.
