RTS HUMIDIFIER RX SERIES INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
Before performing any maintenance, allow the tank to cool down.
• Insulated and uninsulated tanks will have hot surfaces.
• Verify that there is no call for humidity and that the aquastat set point
(adjusted using the display screens in Settings/Water Management) is less
than room temperature (default setting is 50 °F [10 °C]) so the heaters do
not energize while cooling down the tank.
COOL DOWN PROCEDURE
1. Go to the Home screen.
2. Change mode to Drain, and allow approximately half the water to drain
out of the tank. The fill valves may also be on to temper the water.
3. Change the mode back to Auto; the fill valve opens and the humidifier
cools down with the additional cool water.
4. When the fill valve closes, go back into Drain mode, and allow the tank to
drain completely. The humidifier should be cool enough to work on.
Note: For more information about using the display, see the
Vapor-logic Installation and Operation Manual

WARNING
Hot surface and hot water hazard
Do not touch the tank or drain piping
until the unit has had sufficient time to
cool, or serious injury can occur.
Opening the drain valve when the
tank is hot can discharge water with a
temperature up to 212 °F (100 °C) into
the plumbing system. This can cause
damage to the plumbing system.
