Humidification System Installation Recommendations Make your installation accurate and efficient by addressing these commonly asked questions: Sizing for the Job 1. Selecting the appropriate humidifier for the job is critical: The table below illustrates the square footage the humidifier can serve. It is not recommended to install a 6 gallon device in a home larger than 2000 square feet. Square Feet of Space 500 1000 1500 2000 2500 3000 ARI* Recommended Output Delivery (GPD) 0.1 2.2 4.4 6.5 8.
Installation Guide Installation Recommendations Setting Homeowner Expectations for the humidifier Experience: It may take up to a week of continuous operation to achieve the humidity set point, depending on weather, size of home, furnishings in the home, insulation, etc. If using a six (6) gallon unit, the most appropriate setpoint is 30-35% or until there is condensation on the windows, then lower the setpoint.
Humidification System What you will need to install the Humidistat Tools/Hardware needed: Material Provided: • Wire stripper/cutter • 1/4-in. copper or plastic water line • Drill or duct-cutting tool • 1/2-in. drain hose and clamps • 1-3/4-in. hole saw • Mounting bracket and hardware • 1/8-in.
Installation Guide Safety Precautions CAUTION: Voltage Hazard. Can cause electrical shock or equipment damage. Disconnect HVAC equipment before beginning installation. Safety Precautions • Do not direct the steam nozzle at people. • If used near a pool or spa, ensure the humidifier can not fall into the water or be splashed. Also, ensure the humidifier is plugged into a GFI ground fault interrupt outlet. • Water inside tank can be very hot.
Humidification System If installing the humidifier directly to the supply duct, follow steps on pages 5–6 and 14–18. If mounting remote from the duct, follow steps on pages 7–18. DUCT mount installation 1 Choose a location that has access to a: • Drain allowing a slope of 1/4 in. per foot of drain hose. • Cold water line. • Electrical circuit rated to your humidifier. • Vertical surface with adequate clearances. Model RXIH-AS06A RXIH-AS09A RXIH-AS12A Continuous downslope Draining water may be hot.

SUPPLY 4 Drill 1-3/4-in. hole. 12 INCHES M24748 5 Secure bracket to duct using #8 self-drilling sheet metal screws (4). 6 A) Slide foam gasket over nozzle and insert the nozzle into duct hole (pictured). B) Push down to secure humidifier to bracket arms. Ensure gasket forms tight seal in duct hole. Allow 3 in.
Humidification System Remote mount installation Use for mounting to a location other than the supply duct. Most operation problems are caused by improper hose installation. Always ensure an uphill flow when installing the remote hose, and avoid kinks, sharp turns, or low spots that could restrict the flow of steam into the injection nozzle or condensation back into the humidifier. If the remote hose cannot be installed with an upward pitch of 2 in./ft., a wetted drip tee must be installed.
Installation Guide Proper Hose Installs Furnace or Mechanical Room Remote Note: If air handler location temperatures will drop below freezing at any time, the humidifier must be mounted in a conditioned space, running a remote hose to the duct.

Humidification System Troubleshooting The humidifier has internal system diagnostics that monitor system operation, maintenance schedules, and faults. If a system fault is detected, the system will attempt to recover itself up to five times in a 24 hour period. If unable to recover in that time, the red Call Service LED light will activate. If the humidifier Call Service light is red, a system fault has occurred from which the humidifier can not recover by itself.

Humidification System Cleaning and Seasonal or Vacation Maintenance Maintenance is simple with the humidistat—just remove the water tank for cleaning. Warning: Scalding hazard. Do not attempt to remove the humidifier from the mounting bracket during operation, or when the humidifier’s water tank when full of water. Water heater could be hot when tank is removed. Failure to comply could result in severe scalding or death.
