3.11 Pumps supplied with flexible inlet and outlet hoses: The pump inlet and
outlet ports are threaded G ¾ male. These ports are provided with a flat sealing
face suitable for use with an appropriately sized flat faced fitting and fibre or
rubber washer. Ensure a water tight seal is achieved when the pump is both
stationary and running.
a) Hoses incorporating integral isolating
valves should be applied to the inlet
side of pump to satisfy servicing
requirements.
b) Standard hoses with no integral
isolating valve should be applied to
the outlet side of pump.
c) Use correct sized flat headed
screwdriver for opening and
closing integrated isolating valve to
prevent damage.
Please note these valves are of quarter turn design, rotate clockwise to close
and anti-clockwise to open. Failure to comply to these instructions could
lead to valve damage.
d) WARNING - pump must not run with valve closed.
e) Flexible hoses with integral isolating valves do not replace system isolation
valves which must be installed.
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!
