HE360A,B POWERED FLOW-THROUGH HUMIDIFIER
7 69-1176—04
• 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.
— Mount the humidifier in a conditioned space to prevent freezing.
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 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.)
