REVERSE OSMOSIS FILTRATION SYSTEM
This Reverse Osmosis (RO) filtration system
removes dissolved solids and organic matter from
water by passing it through a membrane which
separates and flushes minerals and impurities
from the water.
Install this system upstream of the steam humidi-
fier’s water inlet. It is recommended that the RO
system’s filters be replaced at least once per year
to ensure optimal humidifier performance.
SAFETY GUIDELINES
Read, understand and follow all steps, guides
and requirements before installing the Reverse
Osmosis (RO) filtration system.
All water connections must comply with local
and state plumbing and sanitation codes.
Reference, understand and comply with all gov-
erning codes before installing the RO filtration
system.
Do not install on hot water supply. Only use

Do not install outside or in unconditioned space
where there is potential for the water system to
freeze.
