2.4

Using suitable lifting equipment support the weight of the meter, remove the nuts, bolts and washers

securing each manifold flange to the pipework and withdraw the meter from the system.

2.5

If a replacement meter is not being fitted it is recommended that suitable blanking flanges be fitted to

the open pipework.

INITIAL DISMANTLING

3.1

To assist in dismantling, the meter should be treated as two main assemblies; body and manifold

assembly - calibrating mechanism and register.

3.2

To ensure stability and safety during dismantling place meter in the ring support tool TASS 5010.

3.3

Refer to Fig 5.5. Remove the four screws (13), (53) and washers (14) securing the calibrating

mechanism cover (50) to the base (1). Remove the cover and discard the gasket (54).

3.4

Remove the four bolts (3) and spring washers (3A) securing the base to the front cover of the

bulkmeter. (Pre-1975 models are fitted with studs and nuts).

3.5

Ease the complete calibrating mechanism, register and spacer off the two dowel pins (2) and place

on a clean working surface.
