GENERAL
Congratulations on your excellent choice in this addition
to your home comfort system.
Your humidifier represents both the latest in engineering
development and the culmination of many years of experi-
ence from one of the most reputable manufacturers of com-
fort 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 operation of your humidifier and the small
amount of maintenance it takes to keep it operating at peak
efficiency.
During the heating season, your home can become un-
comfortably dry. This is because cold winter air holds very
little moisture. When outdoor air is warmed to average room
temperature, its relative humidity falls to even lower levels.
Proper humidity control can alleviate problems caused by
excessive dryness. The additional moisture supplied by your
humidifier may enable you to reduce the temperature setting
on your thermostat — without any loss of indoor comfort.
Your humidifier adds water to the air inside your home.
Although the rate of humidification is variable, it may ex-
ceed one-half gallon of water per hour. The typical process
of humidification begins when water flows through the hu-
midifier 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 through-
out the house via the ductwork. See Fig. 1. Typical humidi-
fier installations are shown in Fig. 2.
OPERATING YOUR HUMIDIFIER
Your new humidifier is designed to operate as part of your
home heating system. For performance at maximum effi-
ciency, follow these recommendations:
• The humidifier is controlled by a humidistat. Adjust the
humidistat setting according to the outside temperature. Re-
fer to Table 1 as a general guide. If after several days, the
air in your home is too moist, lower the humidistat setting.
Condensation on single-pane windows indicates exces-
sive moisture. If the air is too dry, increase the setting.
• Continuous blower operation provides for constant hu-
midification. Continuous blower operation also minimizes
temperature differences throughout the home. Further-
more, a system equipped with an electronic air cleaner of-
fers the added benefit of full-time air filtration.
• Supply- and return-air grilles should not be blocked by drapes,
furniture, or other objects. Restricted airflow reduces the
efficiency of the humidifier, as well as that of the whole
comfort system.
• The humidifier unit must be properly maintained on a regu-
lar basis.
