A proprietary torque wrench must be used to perform this operation, failure to tighten the
nuts to the correct torque may result in leakage, failure of the equipment, damage to the
equipment and potential consequential damage.

peripheral equipment), cut power to the control unit by turning the
Mains ON/OFF Power Switch (22) through 90

It is forbidden to alter or use non-original components or
replacement parts without written authorisation. Such acts may
result in serious personal injury and endanger operational safety.
