GETTING
STARTED
Personal Safety
• Wear safety glasses while installing steam humidier.
• Do not cut into any air conditioning or electrical line.
• Follow professional safety standards and all local regulations.
Mounting Location
• Mount steam humidier in a level position to avoid water damage or heating element failure.
• Install steam humidier on the supply duct. Use the Remote Mounting Kit if duct mounting is not possible.
• Do not install steam humidier where the ambient temperature is lower than 34°F (1.1°C) or higher
than 104°F (40°C).
• Mounting area must be strong enough to support steam humidier’s weight when full of water (up to 15 lbs.).
• Choose a location that is well ventilated. Do not install steam humidier in completely enclosed spaces, such
as a cabinet or unventilated closet.
• Allow at least 1 foot clearance to ventilation holes in the steam humidier cover. Do not cover the holes.
Covering them can increase the temperature inside steam humidier and shorten its life.
• Do not mount directly to duct board. The remote mount nozzle attachment is allowed only with a Honeywell
duct board adapter kit. See “Appendix C: Parts List” on page 55.
• If used near a pool or spa, make sure steam humidier can not fall into the water or be splashed. Also, ensure
steam humidier is plugged into a ground fault interrupted (GFI) outlet.
Duct Nozzle
• Do not install the duct nozzle into a supply duct with static pressure exceeding 0.5 in. w.c.
• Do not install the duct nozzle through wooden sidewalls (e.g., oor joist).
• If the duct has exposed insulation on the interior, be sure the nozzle extends beyond the insulation. Clear away
excess insulation at the insertion point, or replace a section of insulated duct (approximately 6 in. x
6 in.) with rigid, non-insulated sheet metal.
• Allow at least 4 in. clearance between nozzle outlet and any interior duct to avoid water condensation.
• Mount steam humidier where the nozzle outlet has a minimum 24 in. of downstream open air space.
Water Drainage
• Consult local plumbing codes for drain size, material, and maximum temperature allowed.
Important Installation Requirements
Failure to comply with these requirements will result in voided warranty, improper installation, and
service callbacks.
