2. Electrical
Refer to section: 'Important Safety Information' first.
2.1 In a domestic installation, the rating of the electricity supplier's fuse and the
consumer unit must be adequate for the additional demand. All Mira Advance
ATLP pumped electric showers are high power appliances, so it is essential to
contact the electrical supply company to make sure that the supply is adequate
for the appliance. Voltage drop due to local heavy demand will reduce the
shower's performance.
2.2 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.
2.3 As a guide only, and in accordance with BS 7671 we recommend close circuit
protection:
i.e.
9.0 kW = 40 Amp
In accordance with BS 7671, a 30 mA Residual Current Device (RCD) MUST
be included in the electrical circuit. This may be part of the consumer unit or a
separate unit.
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 or a wall
mounted switch in the applicable zone area.
2.4 DO NOT exert strain on the terminal block. Make sure that the electrical
connections are tightly screwed down.
2.5 Unless otherwise stated, electrical equipment such as extractor fans, pumps
must not be connected via this product.
