HE220, HE260 HUMIDIFIER INSTALLATION KIT Determining Best Location for Humidifier • Select a location for the humidifier on the supply (warm air stream) or the return plenum. See Fig. 1. • Select a location for the bypass on the opposite plenum. The sidewalls of the humidifier are interchangeable to allow bypass duct mounting on either side of the humidifier. • Select a location that cannot damage the air conditioner A-coil during installation. • Select a location where the 6 ft (1.86m) of 6 in. (155 mm) duct provided is adequate to connect the humidifier to the bypass. - Do not locate the humidifier or bypass on a furnace body. - Allow adequate clearance in front of and above the humidifier so you can easily remove the cover to perform routine maintenance. - Mount humidifier at least 3 in. (78 mm) above the furnace body to allow adequate space for the solenoid valve and drain line. - Mount humidifier in a conditioned space to prevent freezing. HORIZONTAL HIGHBOY Selecting Location for Sail Switch • Select a location for the sail switch in the cold air return duct where the sail is in the direct path of an unrestricted air stream. - Sail switch detects when furnace fan is operating. • Select a location where the air duct is at least 12 in. (305 mm) deep and 8 in. (203 mm) wide to allow operation of the sail without affecting the smooth flow of air in the duct. - Airflow at the location can be vertical (up or down) or horizontal. IMPORTANT Mounting the S688 in warm air supply duct can reduce the sail life. Mount the switch at least 6 in. (152 mm) upstream from an elbow or junction, and at least 15 in. (381 mm) downstream from an elbow or junction. Locate the switch on the opposite side of the duct from the air entrance. (See Fig. 1-3 in S688 Installation Instructions.) 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.) LOWBOY DFOLWON M12248C 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. 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. RETURN AIR ALTERNATE LOCATION RETURN AIR 6 in. (152 mm) MINIMUM BEST LOCATION 15 in. (381 mm) MINIMUM RETURN AIR DUCT M12831 Fig. 2. Selecting duct location for humidistat. Locating Closest 120V Electrical Outlet • Select location with access to an outlet. If not available, contact an electrician to have one installed. Make sure that the 20 ft (6.2m) of thermostat wire is adequate to reach from the humidifier solenoid, to the sail switch, to the humidistat, to the plug-in transformer in the outlet. INSTALLING HUMIDIFIER WARNING Hazardous Voltage. Can cause personal injury or equipment damage. Do not cut or drill into any air conditioning or electrical accessory. 69-1570 2
