WARNING!
TAKE CARE NOT TO DAMAGE THE PRINTED CIRCUIT BOARD IN ANY WAY.
DURING INSTALLATION AVOID DUST AND DEBRIS GETTING ON IT.
8. Do not obstruct the pressure relief device found in the back-plate slot underneath the
outlet connection (see diagram 3). Especially if silicone sealant or similar materials are
used around the edges of the back-plate.
9. There are a number of clearly marked 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 8)
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.
1. It is recommended that a WRAS (Water Regulations Advisory Scheme) listed isolating
valve is fitted between the rising main and the unit. This will allow the unit to be serviced
without turning off the cold water or exchanged without having to turn off the water at the
water mains stop valve.
2. The heater can be fed from a header tank provided this has a minimum head height of
10.5 metres (35ft).
3. Ø15mm copper or stainless steel pipe should be used with a standard compression
fitting. In multiple shower installations correct pipe-work sizes should be calculated to
maintain adequate flow to each shower.
