SIZING
IMPORTANT
The HM700 should only be installed if it has been
sized properly. Do not use square feet when sizing
a humidifier installation. Instead, cubic feet must
be used, since the humidity is filling a volume of
space (width x length x height). Also, take into
consideration the “tightness” of a home’s
construction.
The HM700 produces 11 gallons per day (GPD) when run on
120 V and 22 GPD when run on 240 V. See Figures 15 for
details on configuring the HM700 to run on a different voltage.
Table 3 contains AHRI recommendations for humidity
requirements and Table 4 shows what humidifiers and output
configuration will satisfy the humidification requirements.
