Most qualified contractors are knowledgeable of building codes for general HVAC work. However, many are unaware of five accessories that are mandated by building codes aimed at the fast-emerging ductless mini-split market.

Rather than learn what’s not code compliant from an inspector that red tags a new mini-split installation, the following list of code-mandated products are listed below:

1.Tamper-resistant locking cap for refrigerant ports

2. Condensate overflow switch

3. UV resistant wrap for linesets

4. Condensate drain hose trap

5. An indoor disconnect switch.

These accessories are mandated for a variety of reasons, but they mostly fall under life-safety, efficiency, property protection or a combination of those categories.
