This product can be connected to one of the following power supplies:
Connecting it to any other power source may cause damage.
This product requires a fitted industrial plug to BS-EN
60309 (not supplied), for use with a 110 volt supply. On
no account must a 230V, 13 amp (BS1363) plug be
used.
If using a portable 110V transformer make sure it has a
rated capacity sufficient to take the load of the
pump.
To fit the plug, proceed as follows:
1. Undo the socket screws & remove the rear section.
2. Rotate the cable clamp clear of the terminals.
3. Feed the cable through the rear gland in the plug.
4. Remove the cable sheath to the required lengths
as shown in the diagram.
5. Terminate the correct wires in the
correct terminal blocks.
6. Remove the cable clamp screws. Clip
the cable clamp back into position and
place the clamp around the outer
sheath of the cable. Replace the screws
and tighten until the cable is securely
held.
7. Replace the rear cover and tighten the cover screws.
If in any doubt, consult a qualified electrician. DO NOT attempt any repairs
yourself.

movement of the float switch is not restricted - recommended minimum
area of 50 x 50 cm.
