A condensate drain trap assembly connects to equipment resting on a concrete housekeeping pad with vibration isolators. The piping features a cleanout plug with a removable insulation cap and an open air vent. A sizing table defines dimensions A, B, and C based on static pressure for draw-through and blow-through coil configurations. All piping is insulated as required for condensation protection and terminates with a minimum one-inch air gap above a drain location on a slab or roof.
