WELCOME
Congratulations on your purchase of an HE240 or HE280 whole-house humidifier. Proper use of a whole-house
humidifier has numerous benefits related to your family's health and comfort, as well as helping to safeguard
and protect your home.
How Your Humidifier Works
HE240 and HE280 humidifiers use the principle that vapor (evaporated water) is created when warm air blows
over a water-soaked area. As the vapor circulates, the relative humidity rises.
Your humidity control monitors the relative humidity and activates the humidifier accordingly. The humidifier
has a water supply that dispenses water evenly over a humidifier pad. The warm dry air from the furnace passes
over the humidifier pad and picks up the moist air to circulate it throughout your home.
Humidified air feels warmer and more comfortable so you may be able to lower your thermostat heating
setpoint, which saves money on your heating fuel bills. The end result is that your humidifier gives you a
comfortable environment that is also energy efficient.
Model Specific Features
The HE280 humidifier has water savings technology built in that could save up to 30% versus leading brands.
This translates to up to 20 gallons of water saved per day!
