Operation
Principles of condensate discharge:
1. Start-up
At start-up, the float is sealing the valve seat.
NOTE: If there is no condensate in the trap body,
prime with some water through the pressure-
balancing line before startup.(Do this after
installation and disassembly/ inspection)

Valve Seat
2. Condensate Discharge
As air/gas is supplied, condensate flow begins. The
rising condensate level causes the float to rise due to
buoyancy, opening the valve seat and allowing
condensate to be discharged.
3. Closed Position
When the condensate flow rate decreases, the float
falls, closing off the valve seat opening. A water seal is
maintained at all times over the valve seat to prevent
air/gas leakage.

Specifications
Install properly and DO NOT use this product outside the recommended
operating pressure, temperature and other specification ranges.
Improper use may result in such hazards as damage to the product or
malfunctions which may lead to serious accidents. Local regulations
may restrict the use of this product to below the conditions quoted.
CAUTION
DO NOT use this product in excess of the maximum operating pressure
differential; such use could make discharge impossible (blocked).
CAUTION
Use only under conditions in which no freeze-up will occur. Freezing
may damage the product, leading to fluid discharge, which may cause
burns or other injury.
CAUTION
Refer to the product nameplate for detailed specifications.
