Pipework Connections (Connection between pump and system outlet)
This should run as far as possible in 22 mm copper tube. Pipework should only be
reduced to 15 mm copper if necessary when entering the terminal fittings. By this method
the maximum performance of the pump will be maintained.
STEP 3: PUMP CONNECTIONS (Release and connection of push-in connectors)
WARNINGS:
 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!
The pump is supplied with flexible hoses for connection to inlet and outlet pipework. It
is recommended that only the Stuart Turner hoses supplied are used for making these
connections.
Pipework Connections (Hot)
When a hot water cylinder or storage tank is used, ensure the pipework size from the
cold water storage to the hot water storage is of adequate size and a minimum of 22 mm.
The pump must be supplied with a dedicated feed direct from the hot water
cylinder or storage tank. We recommend the use of the Stuart Top flange Part
No 27800.
The supply must be air free and connection to the cylinder can be made by one of the
methods shown in Fig. 9.
When the method of connection is to be made via the expansion pipe, the cold water
storage cistern should be at least 1 metre above the top of the hot water cylinder.
