6. With the stop valve connected, flush the pipe-work through to remove any particles
etc. , before making the final connection to the shower. Blockage in the waterways
(particularly the handset and solenoid valve) will prevent the heater working properly.
7. The shower is designed to have an open outlet and should only be used with fittings
recommended by the manufacturer. Do not connect the showerhead until after the
shower front cover and removable side section are fitted.
WARNING - DO NOT FIT A TAP ON THE SHOWER OUTLET.
TAKE CARE TO AVOID RESTRICTING THE OUTLET AND FLOW
FROM THE SHOWERHEAD OR THE PRESSURE RELIEF DEVICE.
d) Electrical Connections
The electrical installation must be in accordance with the current BS. 7671 (IEE regulations) and
“Part P” of the Building Regulations. If in doubt consult a qualified electrician.
1. The shower is designed for a single-phase A.C. electrical supply.
Please check the rating plate on the unit to see what details apply.
2. The table is to be used as a guide only. Please refer to the current wiring regulations
For the 9.5kW you may be able to use 6mm² cable if Method 1 (clipped direct) is used.
Remember to uprate the cable if it runs in thermal insulation in a loft, or for longer
distance
3. A means for disconnection in all poles must be
incorporated in the fixed wiring in accordance with
the wiring rules. We recommend a ceiling switch
mounted in a convenient position.
4. Cut back cable as in diagram 10. Connect cable to
terminal block making sure that ALL the retaining
screws are VERY tight and that no cable insulation
is trapped in the block.
