HOW IT WORKS: HOT + COLD = TEMPERED
1. Hot water discharged from a humidifier enters the device through piping/
hose connected to the top (-1 and -2 stage RTS) or side (-3 and -4 stage
RTS) connection. A vacuum breaker prevents backflow into potable water
systems.
2. Cold water enters through the temperature-actuated valve. The valve and
the tempering device’s straightforward design ensure efficient mixing of
hot and cold water. The valve's sensor, located near the outlet, ensures
that water leaving the device is 140 °F (60 °C) or less before entering the
municipal sewer system.
3. Tempered water at 140 °F (60 °C) or less exits through the side outlet for
safe discharge into a municipal sewer system or PVC pipe.
MOUNTING OPTIONS
The mechanical tempering device can be mounted by attaching the integral
mounting plate to a wall or directly to the RTS humidifier.
