Installation protocol:
Maintain horizontal mounting orientation for optimal seal lubrication.
Use alignment jigs during bracket installation to prevent side load forces
(max permissible lateral force: 15% of thrust rating). Pre-charge cushion
adjustment screws 3 full turns counterclockwise before commissioning.
