RTS HUMIDIFIER RX SERIES INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
OVERVIEW
Principle of operation
1. When the system is first activated, the fast fill valve opens, the precision fill valve opens, and the tank fills with
water to the operating level.
2. On a call for humidity, the heating elements are energized, causing the water to boil. The precision fill valve opens
and closes as needed to maintain the operating water level.
3. Steam created in the evaporating chamber flows through vapor hose or piping to the dispersion assembly, where it
is discharged into the airstream.
4. Over time, the tank will drain. Steam humidifiers drain to remove chlorides and minerals from the tank.
• As the humidifier drains, the water will be tempered down to 140 degrees. Drain water tempering can be turned
off in Settings.
• There are a few options when it comes to draining. The Smart Drain setting (default) will detect the cleanliness
of the water and drain accordingly. In User Drain the user is able to set the water usage in-between drains. Both
Smart Drains and User Drains can be scheduled to happen at a specific time in the day (default is 12:00am).
The user can also specify Full Drain or Mini-drain. A Full Drain will drain the tank completely. A Mini-drain will
partially drain the tank. If full tank drains are not permitted, mini-drain shuts the electronic drain water tempering
off. An external thermostatic tempering device would need to be installed to maintain drain water tempering.
5. After the tank drains and refills, a portion of the surface water is skimmed off, carrying away precipitated minerals.
6. If foam is sensed in the tank, the unit will drain and start over with fresh water – regardless of scheduled drain
times.
