MOUNTING THE HUMIDIFIER
Locate the humidifier cabinet level and plumb, using the
level screws (Photo B) on a surface as close to the steam
distributor as possible at a convenient height for servicing.
Allow 12" or more on each side for panel access and 16"
from the bottom of the unit to floor to allow for drain connec-
tions. If there is no common drain within close proximity of
humidifier, a drain pump (Carnes HXWA) may be required
to accommodate this distance. Allow 18"-38" respectively,
in front of cabinet for residential to dual cylinder unit, for
door opening or when necessary, remove door with quick
release pin. (Combo unit and dual cylinder unit have remov-
able doors, residential does not.)
