INLET FLANGE :

After coating it with lubricant, slide the hose boot 6 on

the inlet side over the hose 16 and the pump body 1.

Fit clamps 7 and 9 without tightening them.

Coat the outside of insert 12 with the lubricant, then fit it in

the pipe until the shoulder is in contact with the pipe end.

Fit bracket 18 on insert 12 and screw it on the body

using screws 48 and washers 49.

Fit snap ring 24 in the groove provided for this purpose

on the insert.

Appropriately tighten clamp 7 on hose boot 6. Make sure

that it is not cut 7 (take care on the direction of assem-

bly of the hose clamp : it must be directed so that the

part presenting a lively fish bone is side body).

Tighten hose clamp 9 onto nipple 6 and hose 16 (the

screw should be tightened to the stop).

When starting the pump, check that there is no leakage

between the pump body 1 and the nipple 6. Tight again

the hose clamp 7 if needed.

Repeat the previous operations on the discharge side.
