This appliance must have a permanent mains supply and be
earthed.
Use standard colours for the supply:
Brown = Live (L)
Blue = Neutral (N)
Green/Yellow = Earth (E)
Note~ It is highly recommended that this appliance is connected
to an external control (timer / programmer) as part of the
Approved Code of Practice and guidance Safety and Good
Practice Guide 302.
a) Remove the mains supply plug from the appliance and connect
the electricity supply, the pump supply and appropriate
external controls (using suitable cable) as described below
and with reference to Fig 22.
b) Connect the mains supply Live to terminal L1.
c) Connect the pump Live to terminal L2.
d) Connect the external control (timer / programmer) Live to
terminal L3.
e) If not connecting an external control, it is necessary to link a
switched live between terminals L1 and L3.
f) Ensure all wires are clamped within the plug and that outer
insulation is not cut back beyond the clamp.
g) Ensure all Earth wires are longer than the Live and Neutral to
ensure it will be last to be disconnected should excessive strain
be put on cables.
