Tighten (screw) Discharge Riser into Pumpset until
both inlet centreline identification marks on the
Pumpset are in line with the mark previously placed
on the edge of the Pump Housing Cover. Check this
alignment with a stringline. Do not loosen (back off)
Discharge Riser to achieve angular alignment.
11.Check overall length of Pumpset/Discharge Riser
from Cathodic Insulation Gasket to end of Pumpset
to ensure 5mm (min) clearance to bottom (inside) of
Pump Housing.

Carefully lift the Pumpset/Discha
into a vertical position.
NOTE: When raising or lowering the
Pumpset/Discharge Riser assembly, take care
not to damage the Pumpset, Motor Leads or
conduit. Lift carefully with slings, chains etc.
16.Carefully lower the Pumpset/Discharge Riser
assembly into the Pump Housing making sure that
psthe Pum et does not bind or drag on the sides of
the Pump Housing.
NOTE: Before the Pumpset/Discharge Riser
assembly is completely inside the Pump
Housing, remove the adhesive tape holding t
Cathodic Insulation Gasket to the Pump
Housing Cover. Carefully fit the Cathodic
Insulation Gasket to the Turret Cover.
17.Fit Pump Housing Cover to Turret Cover with
appropriate cathodic insulators/washers for bolts
and nuts. Align marks on Pump Housing Cover and
Turret Cover. The seal between the Pump Housing
Cover and the Turret Cover must be gas tight.
Check that the Pumpset/Discharge
electrically insulated from the tank. If not insulated,
rectify as required.
