9 Hydraulic Installation
Ensure all pressure has been bled from the system before disconnecting any lines or
fittings. Hydraulic pressure will exist on the wing tilt circuits unless the wings are being
supported by other means. You may wish to perform the hydraulic installation with the
wings in transport position, resting on the ground or with the tilt cylinders fully extended.
Component failure due to oil contamination is not covered under the NORAC UC5 system
warranty. It is recommended that a qualified technician perform the hydraulic installation.
