Data subject to change without notice.
IMPORTANT!
The fill-valve orifice is designed for a water
pressure range of 30 to 85 psig (ideally 55 to 60
psig). Contact the factory for water pressures
outside of this range.
The humidifier is designed to operate on cold hard
water.
DO NOT connect to a demineralized or distilled
water supply. (Demineralized water will prevent
operation.)
DO NOT use softened water or hot water.
An isolation valve MUST
be installed in the supply
line ahead of the humidifier inlet.
Use at least 1/2” copper tube to within four feet of
the
Ecos
aire
® unit. Reduce to 1/4”O.D. and connect
to the 1/4” compression fitting on the supply port as
shown.
IMPORTANT!
Be sure the shut-off valve is closed after the
connections are complete. Do NOT open it until
the humidifier checkout procedure.
The humidifier is equipped with a 7/8” O.D.
unthreaded drain outlet on the underside of the drain
canal on the bottom of the humidifier.
Keep drain lines as short as possible.
Keep drain
lines sloped down, not level and not sloped up
since low spots in drain lines will accumulate sed-
iment and cause backup.
The drain line should be
7/8” O.D. copper pipe or larger.
Do Not
use plastic
pipe for drain lines.
