Operation - Honeywell HM600XROF1/U Installation Operation & Maintenance

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 dis-
solved minerals are removed, effectively 'soften-
ing' 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.

OPERATION

#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.
NOTE: It is normal to hear the RO System
operating the first few days after the
initial installation. This will dissipate as
air is purged from the system.
