Standard Features

• Tin−coated Models — WTNC models have tin−coated copper evaporator coils. These coils are
  built with special hairpins which are tin−coated to resist both general pitting corrosion and excessive
  Formicary Corrosion (indoor corrosion, an industry phenomenon).
• Water Management — Coils are designed to avoid water blow−off into the ducts by directing condensate
  away from the fins and into the drain pan.
• Durable Condensate Pan — Coils are equipped with a corrosion−resistant condensate drain pan designed with a slope to help ensure proper drainage, improved moisture removal, and home comfort.
• Compact Design — Unique design offers as much as 2−4" less in height to aid in tight installations.
• Brass Inserts — Every condensate pan features two 3/4" female threaded brass insert connections. The
  unique brass inserts provide for a leak−free condensate line connection to prevent water damage.
• Refrigerant Connections — Coils are provided with sweat−connections for leak−free operation.
• Burst Pressure— Coils meet or exceed burst pressure of 2100 psi.
• Thermostatic Expansion Valves (TXV) — All coils have refrigerant−specific factory−installed TXVs.
• Teflon Ring — Installed inside the liquid line connection at the TXV helps prevent refrigerant leaks. Teflon
  works with both R−410A and R−22 refrigerants.
• Protective Tube Sheets — Protects copper tubing during manufacturing and installation.

Warranty

• − 5 year parts (with an additional 5 years parts if properly registered) limited warranty to the original
  purchaser only for owner−occupied dwellings − see warranty certificate for details.
