Installation Notes

Steam traps should be installed by a licensed pipefitter or plumbing professional familiar with steam system codes including applicable sections of the International Plumbing Code. Shut down and depressurize the steam system completely before removing or installing any trap. Verify pipe connection size and system working pressure do not exceed the trap rating before placing in service. Proper trap orientation per the manufacturer installation sheet is required for correct float and thermostatic element operation.
