6.1 General information
Before undertaking any maintenance on the
trap it must be isolated from both the supply
line and return line and any pressure allowed
to safely normalise to atmosphere. The
trap should then be allowed to cool. When
reassembling, ensure that all joint faces are
clean.
After installation or maintenance ensure that the system is fully functioning. Carry out tests on any alarms
or protective devices.
The compressed air ball float drain trap is a continuous discharge trap, removing condensate the instant it
forms. As soon as condensate enters the main chamber of the trap, the float rises and the lever mechanism
attached to it opens the main valve - keeping the system drained of condensate at all times. When all
condensate has been removed, the float drops and closes the main valve. Float type traps are renowned for
their high start-up load handling capability, clean tight shut-off and resistance to waterhammer and vibration.
