procedures performed by unqualified 

personnel may result in improper 

adjustment and unsafe operation. Either 

condition may result in equipment

Principle of Operation

On startup, air and non-condensible gases enter 

the trap and are automatically vented through an 

accurate balanced-pressure internal thermostatic air 

vent. As condensate enters the trap, the float and 

lever mechanism is raised, lifting the valve off the 

seat, discharging the condensate. Condensate will 

continue to be discharged at the same rate at which it 

is entering. Any air or non-condensible gas that may 

accumulate will be continually and efficiently passed 

by the thermostatic air vent.
