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 humidifier’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 governing codes before installing the RO filtration
system.
Do not install on hot water supply. Only use
cold water supply.
Do not install outside or in unconditioned space
where there is potential for the water system to
freeze.
OTHER REQUIREMENTS
If the RO filtration system or the humidifier are installed in finished space or above ceilings, it is required
to install a water drip pan with a shutoff sensor under all water connections.
See steam humidifier manual, Appendix C.

screws and hanger washers.
4. Hang the RO system assembly on the
hanger washers.
5. Connect Filter Assembly top cover.
6. Connect three filter cartridges in the order
below by turning cartridge to the right,
ensuring thread is properly engaged and
seal is tight.
Align #3 staging tank with RO system
assembly connection #3.
Align #2 RO filter with RO system
assembly connection #2.

PLUMBING
Cut 1/4” dia. tubing lines to fit your installation.
Ensure all cuts are evenly made with no nicks,
scratches or rough spots on the tube end.
Longer tubing lengths – nylon or copper – may
also be used (not provided). Ends of tubing
must be round and free of burrs and scratches
to seal properly.
Install 3/8” x 1/4” adapter elbow into blue outlet
port.
Install 3/8” dia. yellow tube between yellow inlet
port and storage tank valve (Models 50045947001 & 50045947-002). Insert plug from parts
bag in yellow port for Model 50045947-003.
Locate drain line assembly (1/4” dia. red tubes
assembled to flow control coupling). Install 1 ft.
long end of 1/4” dia. red drain line into red port
in the RO system. Route the longer 1/4” dia.
red drain line to a drain. Note that the coupling
contains a flow control that is critical to the
function of the RO system. Make sure the
drain line assembly is installed correctly.
Push tubing completely into applicable fitting by
pushing past initial resistance and then applying
light pulling force to ensure a tight fit.
– To remove tube from connection, depress
collar and pull tubing.

ter and steam humidifier must be checked for
leaks after installation and a short period of
operation.

OPERATION
RO System Assembly
The RO System Assembly directs the flow of
water into the filters in numeric order, and out to
the steam humidifier. A built-in backflow prevention valve prevents the backward flow of water
from the storage tank. The shutoff/check valve
provided with the steam humidifier must still be
installed between the RO system and the steam
humidifier.
#1 Sediment Filter
Cold water enters the sediment filter, reducing
chlorine, sand, silt, dirt and other sediment. This
filters the feed water before entering the RO filter.
#2 Reverse Osmosis (RO) Cartridge
Filtered water enters the RO filter where dissolved minerals are removed, effectively ‘softening’ the hardness of the water. This reduces the
amount of solid mineral (scale/sediment) fallout
inside the steam humidifier’s tank. Reducing the
amount of scale and sediment increases the time
between manual cleanings of the steam humidifier.
#3 Staging Tank Canister
After leaving the storage tank, but before going to
the steam humidifier, water enters the #3 staging
tank canister. This canister holds the initial water
that enters steam humidifier when the solenoid fill
valve opens.
Storage Tank
The storage tank holds filtered water. A
diaphragm inside the tank keeps water pressurized when the tank is full, to provide fast flow
from the RO outlet. The tank is charged with 5-7
psi air. The automatic shutoff valve fills and pressurizes the tank when low, and stops the flow of
water when the tank is full.
NOTE: It is normal to hear the RO System oper-
ating the first few days after the initial
installation. This will dissipate as air is
purged from the system.
