When fitting a spare or replacement switch mechanism
IMPORTANT NOTE
If a spare switch mechanism is fitted at any time, it is important that the magnet system is left in the correct mode.
After installation of a replacement switch mechanism, always check that the B-B contacts are made, assuming the chamber is
empty of liquid. If the chamber is full of liquid, then A-A contacts should be checked to ensure they are made.
If it is found that a switch mechanism is not in the correct mode, then the liquid level in the chamber should be raised such that
the primary float magnet passes through the switching point. Lowering the liquid level will then cause the float magnet to fall
back through the switching point, thus leaving the switch mechanism in the correct operating mode (For a control operating as
low level alarm, the liquid level should be first lowered then raised back to ensure the switch mechanism is in the correct
operating mode).
Full fitting instructions are supplied with each spare or replacement switch mechanism.
