Sheet Metal Drill Bit Determining Best Location for Humidifier Fig. 1. Typical humidifier installation locations. Selecting Water Supply Location • Use either hard or soft water in the humidifier and either hot or cold water. The water flow rate, with the humidifier running, is 3.5 gal/hr (13 liters/hr) to flush the pad and provide moisture for evaporation. • Make sure that the 20 ft (6.2m) of feed water tubing provided is adequate to connect the water supply (saddle valve) with the humidifier solenoid valve. CAUTION Temperature and Static Pressure Hazard. Can cause property or equipment damage. Locate humidifier where ambient temperature is between 32°F (0°C) and 160°F (71°C). Do not install humidifier where freezing temperatures could occur. Be sure supply plenum static pressure is no greater than 0.4 in. wc and water pressure is no greater than 124 psi. • Select a location for the humidifier on the supply (warm air stream) plenum. See Fig. 1. • Select a location that cannot damage the air conditioner A-coil during installation. • Do not locate the humidifier on the furnace body. • Allow adequate clearance in front of and above the humidifier so you can easily remove the cover to perform routine maintenance. - Mount the humidifier at least 3 in. (78 mm) above the furnace body to allow adequate space for the solenoid valve and drain line. Locating Closest Floor Drain • Select location with access to a floor drain to provide drainage for air conditioner condensation and humidifier drainage. • If you do not have a drain available, we recommend that you install the Honeywell Whole House Drum or Disk Humidifier. Make sure that the 10 ft (3.1m) of drain tubing is adequate to reach from the humidifier drain connection to the floor drain. Selecting Location for Humidistat • Select a location for the humidistat on the return plenum or on the wall in the living space. - Mounting on the return plenum is the easiest installation for the control wiring circuit. For return duct mounting, the humidistat should be mounted upstream from the humidifier or bypass so that it is properly sensing the relative humidity of the living space. Locate the control at least 8 in. (203 mm) upstream from the humidifier in the return air duct. (See Fig 2.) 69-2517EF-01 2
