How do I Install a Nortec Humidifier Tank?

Nortec humidifier tanks are used to replace the moisture in a room or area that has excessively dry air. Since dry air actually carries more germs than moist air, humidifiers also help remove contaminants and dust particles which can irritate your sinuses. The optimal humidity for a healthy room is between 30 and 50 percent, and monitoring for healthy humidity levels can be done with a humidity gauge. Humidifiers are stand-alone units that are generally mounted on a wall and are serviced with water from a holding tank. Installing the Nortec humidifier tank's supply and drain lines is the most important part of tank installation.

Instructions

- 1
  Check local codes where you live for humidifier check valve requirements. Some cities and municipalities require spring-loaded double ball check valves for installed humidifiers on every potable water inlet of every humidifier. Size these valves based on the in and out supply lines.
- 2
  
  Humidifiers should be used in rooms which are exposed to direct sunlight to maintain humidity levels.
  
  Plan and lay out a cold water supply line only. Humidifiers supplied with hot water tend to accumulate mineral buildup and clog the fill valve's small orifice quickly. If your cold water is excessively hard, consider adding a water softener for extended cylinder life in your Nortec tank; the downside here is that soft water tends to be more corrosive and more conductive.

  Refer to local plumbing codes and install the supply line in full accordance with all codes. Be sure to mount a convenient supply line cutoff. Use 1/2-inch OD (outer diameter) copper to within 48 inches of the humidifier, reducing down to 1/4-inch OD copper at the last 48 inches up to the humidifier's compression fitting. Obey local codes if they differ in copper line size and lengths than what this step gives.

  Clear, clean drains are key to maximum humidifier function.
  
  Check the drain connection on your Nortec humidifier tank. For a smooth, straight 7/8-inch OD drain canal with no threads on the bottom of the humidifier, a reducer may be necessary. Confirm this with your local applicable codes and install a reducer if required; it also helps to prevent drain pan and cylinder backup due to clogs.
- 5
  Route the drain connection into a floor drain or locally permitted outlet, since humidifier water gets very hot. Do not route the drain line where people might come into direct contact with the humidifier water.
- 6
  
  Avoiding 90 degree turns improves the likelihood of never having to deal with clogs.
  
  Keep the tank's drain lines as short as possible and avoid 90 degree turns. Angle them down to increase water flow. Use 7/8-inch OD copper or larger and do not use PVC or other plastic pipe for the drain lines.
