1. Lift the silencer using suitable lifting
equipment onto the valve (see informa-
tion under 'Lifting the silencer' in the
'Shipment and on-site transport' section).
Pay attention to the directions of flow for
the silencer and valve before lifting. Both
directional arrows must point in the same
direction.
2. Use the correct flange gasket.
3. Use the supplied studs and nuts to bolt
the silencer and valve together.
The number of studs and nuts varies de-
pending on the number of holes in the
valve and silencer flanges.
Observe the usual tightening torque for
the corresponding bolt diameters. Apply
the full tightening torque gradually in a
crisscross pattern.
