Fitting the pipes
The unit should be connected directly to the main cold water supply.
We recommend that you use Ø15mm copper or stainless steel pipe for the inlet and outlet
connections. (See addendum sheet for local installation requirements).
Use PTFE tape for making screw joints. Do not use a jointing compound.
Remember to keep the hot water pipe runs as short as possible.
If the unit is to supply more than one basin outlet, the height should be the same at each outlet
if they are to be used at the same time. If not, one outlet will take all the water.
In some cases, it may be worth fitting a second unit.
When the pipework has been plumbed in, flush it through with water before you connect the
unit, to remove any swarf or loose particles.
Connecting the unit to the pipes
The inlet and outlet are clearly marked on the unit.
UK models have Ø15mm straight shank connections.
Other export models are fitted with ½” NPT connections.
The unit comes with a service valve (diagram 5) which should be fitted on the inlet of the unit.
Models have either Ø15mm straight shanks or ½” NPT connections. Check to see which applies.
The valve can be used to turn off the water supply to the unit if it needs servicing, or to reduce
the main supply flow if it is too high (see “Powerstream-Eco commissioning” section on page 9).
Fitting the attachments
If the unit is to supply a shower, you will also need a “Redring Mixer Unit”. Available in
chrome/white finish and suitable for surface or concealed pipe entry (see page 15 for details).
If the unit is to supply a shower, and the shower handset can reach water in a bath or basin, you
must fit a vacuum breaker to comply with Water By-laws.
Alternatively, use the hose-retaining feature built into the soapdish.
Because water can sometimes seep through, you should position the vacuum breaker where
dripping will not do any damage.
If the unit is to supply a basin or two basins, we recommend that you use
“¼ turn lever control spray taps” (see page 15 for details).
