Redring 620 - Manual (Page 7)

c) The handset must not be able to come into contact
with any used water in the bath or basin. If it can,
even after the hose has been retained by the hose
retainer (see diagram 13), then a vacuum breaker
must be fitted. It should be noted that these
devices are liable to minor leakage so they must
be positioned so that any drips are not detrimental.
4. Fix the riser rail with screws provided. The fixing holes
at the base of the brackets will be disclosed by
removing the plastic fronts. Assemble as shown in
diagram 13.
5. Decide the position of the electrical cable inside the
unit. If top or bottom entry is chosen (according to
diagram 6), cut away the walls of the back-plate as
shown in diagram 8. There is also the option to fit the
cable from the rear in the channel provided.
6. Decide the cut away position of entry of the cold water
pipe into the unit. Cut away the back-plate and front
cover as shown in diagram 7 or 8. There is also the
option to have rear entry (see later section on
plumbing).
7. If you have not yet done so, remove the front cover
(complete with control knob) of the unit by undoing the
retaining screws at the top and bottom of the unit and
lifting the cover off. The top-fixing hole is a keyhole slot,
and should be marked and drilled first. Tighten top
screw with head protruding about 10mm from wall and
hook the back-plate over the screw head. This allows for
correct and accurate alignment of your shower before
marking and fixing the bottom/side position. You may
not wish to tighten up all 3 other screws at this stage as
the holes are elongated to allow for adjustment after
other connections have taken place.
8. Do not obstruct the pressure relief device found in the
back-plate slot underneath the outlet connection (see
diagram 2). Especially if silicone sealant or similar
materials are used around the edges of the back-plate.
9. There are a number of shields in the shower unit.
These are important for the correct operation of this
shower and MUST NOT be removed under any
circumstances.
b) Plumbing (see diagram 9)
The heater should be connected to the mains cold water supply. This must have a minimum
running pressure of 100kPa, 1.0 bar (14.5 p.s.i) and a maximum pressure of 1000kPa, 10 bar
(145 p.s.i).
Before connecting the pipe-work to the shower ensure that pipe-work is flushed out.
