the model 400k uses 100% of its water
Evaporative humidifiers use forced-air heat to provide pure vapor
humidity. The fundamental operation of the Aprilaire Model 400K
is no different. The difference is the design of the water panel.
The Model 400K utilizes “wicking” water panel technology.
This eliminates the need to flow water through the panel and
significantly reduces the amount of water needed which could be
up to 5 gallons of water per hour of operation. Simply replace the
water panel twice per season and enjoy the benefits of proper
humidity and conserve natural resources.
^NOTE:
Heat pumps – Model 400K can be installed in heat pump applications. However, due to the fact that heat pumps deliver lower
temperature air to the home than gas furnaces, evaporation will be approximately 60 % of rated capacity. (With other Aprilaire models hot
water can be used instead of cold to maximize evaporation. However, due to the nature of the wicking water panel in the Model 400 hot water
provides less benefit.) As such, your dealer will need to take the size and age of your home into consideration to ensure the Model 400 will
provide satisfactory comfort and protection through adequate humidification.

For those rare occurrences where an automatic control is not practical, Aprilaire digital control can be installed in manual mode while still delivering the accuracy and
information you need for optimum performance.
Warranty –
All Aprilaire models are warranted for five (5) years from date of installation for parts.
Heat Pumps –
Plumbing the humidifier to hot water is recommended on all heat pump installations or if it is installed to operate independently of a call for heat.

Water feed rate for the Model 700, 350, and 360 is 6 gph; the Models 500 and 600 is 3 gph;
Model 400 is .7 gph: Model 800 is .6 gph when connected to 120V, 1.1 gph when connected
to 208V and 1.18 gph when connected to 240V. (gph = gallons per hour)
Evaporative capacities assume blower active 100% of the time, and plenum temperatures at
120
˚F and cold water.
