RTS HUMIDIFIER RX SERIES INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
INSTALLATION
Piping: Drain water tempering
STEP-BY-STEP INSTALLATION INSTRUCTIONS
1. Verify that maximum flow of hot water into the device does not exceed 6
U.S. gallons per minute (gpm) (22.7 L/m).
2. Note that there are three connections to be made:
• Cold water supply
• Hot water inlet from RTS
• Tempered water piping to drain
3. Position unions on all connections as close to the device as possible to
make cleaning and maintenance easier.
4. Cold water supply connection instructions:
• Cold water supply connection on valve is 3/8" (DN10) pipe thread (for
dedicated tempering water source).
• Pipe a 3/8" (DN10) line directly to the device from the main water
supply line (for dedicated tempering water source)
To ensure adequate water pressure to the mechanical tempering
device, do not connect to a supply water line that is dedicated to other
appliances .
• For single source water connection, use supplied tee on supply line to
feed cold water supply on tempering device.
• Verify that the supply water pressure to the valve is at least 25 psi (172
kPa) and not more than 80 psi (552 kPa).
• Install a cold water supply union as close to the device as possible.
• Install a cold water shut-off valve before the union in the cold water
supply line.
5. Hot water inlet connection instructions:
• Hot water inlet connection is 1" (DN25).
