Pressure relief safety device
A pressure relief device (PRD) is designed into
the shower unit which complies with European
standards. The PRD (Fig.13) provides a level of
appliance protection should an excessive build
up of pressure occur within the shower.
IMPORTANT: If the PRD operates, then water
will eject from the clear PRD tube.
If the shower installation option chosen uses
the bulkhead fitting, make sure the PRD tube,
when eventually installed, is routed carefully
to waste e.g. via a tundish and pipework
directed to an external point (fig.14).
If the shower installation option chosen is a
through the ceiling fitting, then the PRD tube
will follow the heated water pipe along the
inside of the riser rail and terminate at the
base of the riser rail (fig.12).
In the event of the PRD operating, turn off the
electricity and water supplies to the shower
at the isolating switch and stopvalve. Contact
Customer Service for advice on replacing the
PRD.
DO NOT operate the shower with a damaged or
kinked shower hose, or a blocked showerhead
which can cause the PRD to operate.
When commissioning, the showerhead must be
removed from the flexible hose. If not removed,
again it may cause the PRD to operate.
