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 ‘Redring’ 
recommended fittings. 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 (I.E.E. 
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. 
For the 9.5kW you 
may be able to use 6mm² cable if Method 1 (clipped direct) is used. 
  Remember to up rate 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.
