SPARE SWITCH MECHANISMS

Switch Mechanism Replacement
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, and the switch is located on the pressure tube to allow it to
trip in both directions, 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 switch 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.
