General Maintenance - GCE MM40 - HP UNIT Instrucciones De Use

9. ROUTINE MAINTENANCE INSTRUCTION
Routine maintenance shall be carried out only by authorized person according to national
standards. Use only original GCE components. Contact GCE for further information about repair
procedures.
9.1. THE FOLLOWING ROUTINE CHECKS
- should be made on a weekly basis:
Check all valves for correct operation and leak test using a laek detection fluid.
•
Check pipe work for leaks using a leak detection fluid.
•
Check that all notices are in place, can be easily read and are not obstructed from view.
•
Inspect the vicinity of cylinders for anything introduced since last inspection, which could
•
affect the continuing safe operation of the manifold.

9.2. GENERAL MAINTENANCE

- should be undertaken in accordance with a planned maintenance schedule, which should
include the following items:
Leak test all connections using a leak detection fluid.
•
High pressure hoses should receive particular attention to ensure they are secure, not worn
•
or otherwise weakened.
Components with limited lifetimes, such as high pressure hoses, should be subjected to a
•
routine replacement programme.
Filters are in good condition and not blocked. Filter elements may need to be cleaned or
•
renewed and pipelines may need to be blown through to remove foreign material.
Valves to be used in normal or emergency operation are accessible and easy to operate.
•
Valves at service point's outlets and purge valves should be checked for gas tightness.
The setting and operation of regulators is satisfactory.
•
The necessary safety devices and instruments are fitted, are of the correct type and do not
•
show signs of deterioration or not authorized interference.
The equipment downstream of the outlet point is suitable for further service.
•
Check connecting nuts and seating faces are undamaged.
•
Check gauges operate smoothly and zero correctly.
•
Check isolating valves for closure tightness and gland leakage.
•
The gas manifold room must always remain thoroughly clean. Materials other than those
•
required for operating the manifold must not be stored in the room.
Replace all worn or damaged parts with original spare parts. Remember that gaskets, o-rings
•
and sealing surfaces must be clean and free from damage to work effectively.
Safety note-as part of the planned maintenance special checks should be made to ensure:
All changes (including removal and addition of parts) and extensions conform to the right code
of practice.
Changes in the vicinity of the installation do not affect the safety of the operation e.g. proximity
of electricity to fuel gases, oils and combustibles near to oxygen, illicit use of a pipeline as an
electrical conductor or as a support for other items.
