OPERATION
The HE225A,B and HE265A,B 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.
The humidity control monitors the relative humidity and
activates the humidifier accordingly. The humidifier has a
water supply that disburses water over an antimicrobial
humidifier pad. The warm dry air from the furnace passes
over the humidifier pad and collects moisture and them
circulates it through the house.
Humidified air feels warmer and more comfortable so the
homeowner may be able to lower the thermostat heating
setpoint and save money on heating fuel bills. The end result
is that the humidifier gives the homeowner a comfortable
environment that is also energy efficient.
MAINTENANCE
A regular maintenance program prolongs the life of the
humidifier and provides a more comfortable environment.
Either hard or soft water can be used in the humidifier.
Frequency of cleaning depends on the condition of the water.
CAUTION
