B.ADDITIONAL MAINTENANCE

(1)In addition to the maintenance items listed in this guide, the NH Series Installation Guide lists other maintenance items that apply the entire NH Series (indoor and outdoor). Refer to the NH Series Installation Guide for further details and procedures.

4.WEATHER DESIGN DATA

A.WEATHER DATA

(1)The following weather design data is provided to assist in determining suitable locations for rooftop mounting of the NH Series Outdoor models. Climates that see very cold winter conditions are not good candidates for rooftop NH units. It is NOT recommended to install the humidifier in areas that reach below 14°F (-10°C) during January, or above 122°F (50°C) during July (see table below). These harsh climates can cause required maintenance to be difficult to perform and increase the risk of the humidifier freezing or overheating.
