METHOD OF OPERATION The microswitch assembly inside the float, axially mounted in line with the weight, changes contacts according to the floats position - see diagram. Therefore as the liquid level drops or rises slowly, a pump or flow control suitably connected can be switched in or out to maintain an average level of the liquid. By connecting only one side of the switch, the unit can be also used to fill or empty the tank as required.

MOUNTING Whilst no hard and fast rules apply to the mounting of these units, the lead should be supported in an enclosed vessel, and in an open vessel it is advantageous to clip the lead to the side, especially if excessive turbulence is experienced.

To obviate the effects of rapid switching conditions that would result if such turbulence is experienced, it is advantageous to use a maintaining circuit which both safeguards the microswitch and cuts out any chatter in the starters of associated pumps etc.

ELECTRICAL CONNECTIONS Connect the BROWN lead to the COMMON/NEUTRAL connector and the other leads as follows:

A. To drain a pit/sump etc., Connect the BLACK lead to the LIVE connector.

B. To Fill a tank Connect the BLUE lead to the LIVE connector

Ensure any connector boxes in close proximity of water are fully waterproofed.

If in any doubt, regarding electrical installation, consult a qualified technician, DO NOT attempt to carry out the installation yourself.
