Aprilaire 600 Humidifier User Manual

Capacity is high because an average-size home (10,000 cu. ft.) requires
the addition of approximately 9 gallons of water per day to maintain 35%
relative humidity when the outside temperature is 20°. The smallest
Aprilaire Humidifier under most operating conditions, has this humidifying
capacity. Trouble-free performance and minimum maintenance are
assured by the design features of the Aprilaire Humidifier. All unit
housing parts that come in contact with water are non-metal and will
never rust or corrode. Neither heat nor water will affect them under
normal operating conditions.
The Water Panel evaporator, designed especially for uniform, high
evaporation, along with the Scale Control Insert efficiently traps mineral
deposits which are often the cause of damage to working parts in
ordinary humidifiers. No “white dust” can be distributed throughout the
living quarters. The Water Panel evaporator is the heart of the unit and
must be in good condition to assure high capacity trouble-free
performance. It should be changed once a year with the exception of the
Model 400 where it should be changed twice a heating season.
The granular coating in the bottom of the distribution tray is designed to
provide equal distribution of water to each of the openings assuring an
even flow over the Water Panel evaporator. Do not clean the mineral
scale off the bottom of the water distribution tray at the end of the
humidification season. The scale itself provides an excellent track for the
water to follow. This is actually what we try to simulate with the
synthetic coating in the bottom of the tray. If the coating is removed, it is
not necessary to purchase a new distribution tray. You can accomplish the
same uniform performance by applying a small amount of liquid
dishwashing detergent over the entire inside surface of the water
distribution tray. This will allow the water to flow evenly through each of
the openings, provided, of course, the unit is level in order to achieve
maximum capacity.
There are many humidifiers on the market. They all add moisture… with
varying degrees of efficiency. None, however, can provide the features,
design, and performance incorporated into your Aprilaire Humidifier.
