1 GENERAL INFORMATION
1.1 The following procedures are to be carried out by suitably qualified engineers with full workshop
facilities available. It is possible to carry out some dismantling with the meter in-situ, i.e. to renew a
seal; a clean working area must be maintained at all times during servicing operations.
1.2 If two or more meters are to be overhauled at the same time, it is recommended that they are
dismantled and re-assembled separately to avoid any mixing of components.
1.3 Special tools as shown in Fig 5.1 have been designed to assist in dismantling and re-assembling.
Note:
Procedures are described in respect to a single capsule meter (Figs 5.2 and 5.4 refer), double
and triple capsule procedures are identical except for extra drain plugs and separation of body
casings which is only necessary to renew gaskets.
WARNINGS
WORK MUST BE CARRIED OUT ONLY BY SUITABLY QUALIFIED PERSONNEL.
PRIOR TO COMMENCING WORK, ENSURE THAT ALL AIRPORT/COMPANY SAFETY
PROCEDURES HAVE BEEN COMPLIED WITH.
2 REMOVAL FROM SYSTEM
