Refreshing Moisture AS Nature Intended

REFRESHING MOISTURE . . .

AS NATURE INTENDED

Congratulations on your excellent choice and sound investment in this addition to your home comfort system.

Your humidiﬁer represents both the latest in engineering devel- opment and the culmination of many years of experience from one of the most reputable manufacturers of comfort systems.

Your new unit is among the most energy-efﬁcient and reliable home humidiﬁers available today. To assure its dependability, spend a few minutes now with this booklet. Learn about the op- eration of your humidiﬁer and the small amount of maintenance it takes to keep it operating at peak efﬁciency.

With minimal care, your humidiﬁer will provide you and your family with moist, spring-fresh air — from season to season and year to year.

YOUR HOME HUMIDIFIER

YOUR HOME CAN BE DRIER THAN DEATH VALLEY

During the heating season, your home can become uncomfort- ably dry. This is because cold winter air holds very little mois- ture. When outdoor air is warmed to average room temperature, its relative humidity falls to even lower levels. Refer to Table 1 for a comparison of the levels of relative humidity for a few sam- ple environments.

Parched air can cause the wood used in the construction of your house and furnishings to dry, crack, and split. Draperies and up- holstery may age prematurely. Annoying static electric shock and cling are more prevalent. Your throat, nasal passages, si- nuses, and skin are more susceptible to irritating dryness. You may even have to set the thermostat higher than otherwise nec- essary — just to feel warm.

MOISTURE MAKES A REFRESHING DIFFERENCE

Proper humidity control can alleviate problems caused by exces- sive dryness. Furnishings and fabrics take on a more lustrous appearance. Houseplants thrive. Static electricity is signiﬁcantly reduced in a properly humidiﬁed home.Your family will breathe more easily and ﬁnd relief from the cool, drafty feeling com- monly experienced in overly dry homes. The additional moisture supplied by your humidiﬁer may enable you to reduce the tem- perature setting on your thermostat — without any loss of indoor comfort.

HOW YOUR HUMIDIFIER WORKS

Your humidiﬁer adds water molecules to the air inside your home. Although the rate of humidiﬁcation is variable, it may exceed one-half gallon of water per hour. That’s a healthy drink for a dry household. The typical process of humidiﬁcation be- gins when water ﬂows through the humidiﬁer valve and soaks

the large evaporator pad. Hot, dry air from the furnace passes through the pad and absorbs the water. Then, this moisture-laden air is distributed throughout the house via the ductwork. See Fig. 1, 2, and 3.

OPERATING YOUR HUMIDIFIER

Your new humidiﬁer is designed to operate as part of your home heating system. It will perform at maximum efﬁciency if these recommendations are followed:

•The humidiﬁer is controlled by a humidistat. Adjust the humidistat setting according to the outside temperature. Refer to Table 2 as a general guide. If after several days, the air in your home seems too moist, lower the humidistat setting. Con- densation on single-pane windows indicates excessive mois- ture. If the air is too dry, increase the setting. Dry throat and nasal passages indicate dry air.

•All models come with a humidistat. Continuous blower oper- ation provides for constant humidiﬁcation. It may also contrib- ute to greater personal comfort because continuous blower operation minimizes temperature differences throughout the home. Furthermore, a system equipped with an electronic air cleaner offers the added beneﬁt of full-time air ﬁltration.
