Plumbing

1. A minimum storage capacity of cold water of 230 litres (50 gallons) is required
to provide adequate showering time. Insufficient storage may result in the pump
being run dry.
2. Layout and sizing of pipework must be such that nominally equal inlet supply
pressures are achieved and the effects on the shower performance of other
draw-offs are minimised. Make sure the shower unit is the first draw-off from
the water supply.
3. Avoid routing the high level hot feed pipe upward to the same level as the cold
tank e.g. into loft space, as air locks may result.
4. Do not solder supply pipework connected to the shower unit as heat transfer
may damage plastic components.
5. Do not use jointing compounds on the shower unit joints, they may cause
damage to the mechanism inside.
6. Do not insert fingers into the push fit connections.
7. The supply pipe ends must be free from burrs, as these will damage the push
fit seals.
8. Do not use stainless steel piping for inlet pipework.
9. If plated tubing is used for inlet pipework remove the plating from the last 25 mm
of the tube to make sure of a good seal.
10. 15 mm polythene plastic pipe suitable for hot water may be used to supply the
shower unit, but internal pipe supports must be used.
11. Supplies must be thoroughly flushed to remove any debris before connecting
the shower unit.
12. Fit non-restrictive (free-flowing) isolating valves in the inlet pipework to the
appliance. Make sure that you can access the isolating valves easily.
