3 PUMP CONNECTIONS

3.11 Hose to pump: The pump inlet and outlet ports have moulded fittings which

are specifically designed for connection to the G ¾ female running nuts on the

flexible hoses. The hose end running nut is fitted with a rubber sealing washer

which is held captive within the nut assembly. Locate the hose into position and

screw the nut fully onto the fitting by hand. Finally nip tight with pliers (4/5 Nm)

for a water tight seal (do not overtighten).

Do not use stainless steel, chrome or nickel plated pipe with

the flexible hose push-in plumbing connections.

Do not introduce solder flux into the joint or surrounding area

as connectors will be attacked and may fail.

All solder joints should be completed and flux residues removed

before final connection to push-in connections, on the flexible

hose.

Do not allow contact with oil or cellulose based paints, paint

thinners or strippers, acid based descalents or aggressive

cleaning agents.

Never operate pump with inlet and/or outlet isolating valves in

the closed position. Damage will occur!
