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.
Selecting Location for S688 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.
