Note
All control components have been adjusted to correct
values during fabrication. Do not change these values
without written consent from EMCO WHEATON.
6.2 Installation of Feed Lines
Only persons with the required training and qualification (i.e. electricians for the
electrical systems or mechanics for the pneumatic and hydraulic system) are al-
lowed to work on the electrical, pneumatic and hydraulic system.
Install and connect all pneumatic and hydraulic lines according to appropriate
industry standards. Fittings, dimensions and quality of the components must be
selected to meet the requirements of the installation.
Clean all pipes and containers from dirt (scales, sand, swarf etc.) before installa-
tion.
Connect the electrical system, the pneumatic system and the hydraulic system (if
applicable) according to the diagrams and data sheets in the appendix.
All components have been adjusted to their values during fabrication. Do not
change these values without our written consent.
Only use dry and clean air or nitrogen for the pneumatic system.
7 Commissioning
Do not operate the loading arm when you notice any damage. Please contact
EMCO WHEATON.
Purge the system (loading arm and pipes) before using for the first time to avoid
damaging the swivel joints and fittings.
Perform the following tests:
Leakage Test
Leak test by means of air or nitrogen of 7 to 15 psi and a foam-forming
substance.
Operating Range/Balancing
Check the operating range once again by moving the A/B/F-lengths of the
loading arm into the extreme positions. Verify with the help of the general
arrangement drawing.
Functional Test:
Operate the loading arm as described in Section 8. Test the function of all
instruments, accessories and signals.
Do not exceed the allowable operating pressure and operating temperature.
