by qualified personnel authorized by Condair.
All personnel working with the Reverse Osmosis System unit must be familiar with, and comply with the
appropriate regulations on workplace safety and prevention of accidents.
Intended Use
The is intended exclusively for air humidification using a Condair-approved within specified operating
conditions. Refer to "Technical Data" on page19 for details. Any other type of application, without the
express written consent of Condair, is considered to be NOT conforming to its intended purpose, and

Safety Precautions that Must be Observed
DANGER!
Risk of electric shock!
The Reverse Osmosis System is 24 VAC powered. Live parts may be exposed when the access
panels or doors are removed. Touching live parts may cause severe injury or even death.
Prevention: The Reverse Osmosis System must be connected to the humidifier only after all mounting
and installation work has been completed and checked for correct workmanship, and the access pan-
els/doors to the humidifier are closed and fastened securely.
Only qualified personnel should perform maintenance or repairs on the unit.
Follow any lockout procedures when servicing the unit.
DANGER!
Poorly maintained RO-U systems may be hazardous.
Poor maintenance of the Reverse Osmosis System poses a health risk to spaces humidified by
the Ultrasonic Humidifier. When adequately operated or poorly maintained, micro-organisms that
cause disease, such as Legionnaire's, may grow in the water system and in the humidifier which
dispel the micro-organisms into the air.
Prevention: Read, understand, and follow maintenance guidelines to ensure the humidification sys-
tem remains safe. Ensure that the unit is cleaned and disinfected, as directed in this manual, and
avoid shutting off the unit (max. 48 hours). If the unit has been off for 48 hours or more, disinfect and
flush the system thoroughly before humidifying the space with the Ultrasonic Humidifier.

WARNING!
Do NOT leave the unit without power. Risk of contamination.
Do NOT leave the unit unpowered for more than 48 hours, or else a total system disinfect will be
required. Without power, the system will not flush properly, resulting in standing water and con-
ditions that may promote the growth of micro-organisms.
Prevention: Leave your unit powered on. If you do not need humidification during the 48 hours, set
the humidifier to standby or set the demand to 0.
WARNING!
Risk of contamination.
Do NOT use oil, grease, glue, Teflon, silicon, O-ring lubrication, etc. when assembling pipes or
hose connections. All of the above products can act as food for bacteria, posing health risks.
Prevention: For lubricant, use dish soap. Wash hands and wear clean gloves while assembling parts
in direct contact with water. Keep dust covers on pipes and hoses until assembly.
WARNING!
Water from RO-U systems may cause metals to corrode quickly.
Water produced from a Reverse Osmosis System is aggressive and can cause some metals to
quickly corrode. The RO-U system should always be connected to piping and equipment that is
suitable to handle RO water.
Prevention: Read, understand, and follow maintenance guidelines to ensure the humidification sys-
tem remains safe.
CAUTION!
The RO-U System contains pressurized water.
Hoses in the RO-U System contain pressurized water that may spray if the hose connections are
loose or there is a leak.
Prevention: Do not re-tighten or unscrew hoses while the system is pressurized. Test for leaks and
replace broken hoses.
CAUTION!
Do NOT fasten the RO-U System, including the tank, hoses, and pipes to vibrating surfaces.
