Electrical - Mira JUMP Installation And User Manual

Electrical

1. In a domestic installation, the rating of the electricity supply company fuse
and the consumer unit must be adequate for the additional demand. This is
a high-power appliance, and it is essential to contact your electricity supply
company to ensure that the supply is adequate for the appliance. Voltage drop
due to local heavy demand will reduce the performance of the shower.
2. The appliance must be earthed by connecting the supply-cable earth conductor
to the earth terminal.
Supplementary bonding: Within the bathroom or shower room, all accessible
conductive parts of electrical equipment and extraneous conductive parts that
are likely to introduce earth potential, must be electrically bonded to earth using
a minimum cable size of 4.0 mm
(2.5 mm if mechanically protected).

3. The minimum cable size (cross-sectional area) must conform to BS 7671.
4. To obtain full advantage of the power provided by this unit, use the shortest
possible cable route from the consumer unit to the shower.
5. In accordance with BS7671 a 30mA Residual Current Device (RCD) must be
included in the electrical circuit. This may be part of the consumer unit or a
separate unit.
6. A separate, permanently connected
supply must be 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 pull-cord type within
the shower room or a wall mounted
switch fitted in the applicable zone
area.
7. Unless otherwise stated, electrical
equipment such as extractor fans,
pumps must not be connected via
this product.
8. DO NOT twist the individual cable cores of the live and neutral conductors, as
this will prevent them from entering the terminal block.
9. DO NOT exert strain on the terminal block. Make sure that the electrical
connections are tightly screwed down.
10. DO NOT turn-on the electrical supply until the plumbing has been completed.
