2. The appliance must be earthed by connecting the supply-cable earth conductor
to the earth terminal. Any supplementary bonding and supply cable size must
conform to BS 7671.
3. As a guide only, and in accordance with BS 7671 we recommend close
circuit protection:
i.e. 8.7 kW = 40 Amp
9.8 kW = 45 Amp
4. For new installations a 30 mA Residual Current Device (RCD) must be
incorporated into the electrical supply to the shower in accordance with the current
wiring regulations. When replacing an existing electric shower we recommend
that a 30 mA RCD is incorporated in accordance with current wiring regulations
if not already provided.
5. A separate, permanently connected supply must taken from the consumer unit
to the appliance through a double-pole switch, which has at least 3 mm contact
separation. The switch can be a ceiling mounted pullcord type within the shower
room or a wall mounted switch in the applicable zone area.
6. DO NOT exert strain on the terminal block. Make sure that the electrical
connections are tightly screwed down.
7. DO NOT turn on the electrical supply until the plumbing has been completed.
8. Unless otherwise stated, electrical equipment such as extractor fans, pumps
must not be connected via this product.
