Capacity is high because an average 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 also 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 annually.
Older design water distribution trays have a granular coating in the
bottom of the distribution tray 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. If
the granular 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 soap over the entire inside
surface of the water distribution tray. This will allow the water to flow
evenly through each of the openings, provided the unit is level in order to
achieve maximum capacity.
The current distribution tray which incorporates a synthetic fabric liner
that replaces the granular coating, is designed to deliver water uniformly
over the entire top surface of the Water Panel evaporator, provided it is
mounted level. It is normal for some mineral deposits to form in the
distribution tray as it dries out between humidification cycles. These
deposits can actually help distribute water in the tray, but if they form
enough to block the openings, they should be removed as described in the
“Periodic Preventative Maintenance” section of this manual.
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.
