safety precautIons
cautIon: Voltage hazard.
Can cause electrical shock or equipment damage.
Disconnect HVAC equipment before beginning installation.
Warning: electrocution, heavy equipment, and Water hazard.
Can cause death, blindness, water damage to home and heating element failure.
Warning: steam condensation, fire, and freezing Water hazard.
Can cause failure of fan or limit control or result in water damage to home.
contractors: Important InstallatIon requIrements
Failure to comply will result in voided warranty, improper installation, and service callbacks.
• Do not direct the steam nozzle at people.
• Water inside tank can be very hot. Explain this to homeowner and emphasize the warning label on TrueSTEAM.
• Do not cut into any air conditioning or electrical line
• Wear safety glasses while installing TrueSTEAM.
• Mount the humidifier in a level position to avoid water damage or heating element failure.
• Install TrueSTEAM on the supply duct. Remotely mount TrueSTEAM to the supply duct if direct mount is not
possible.
• Do not install the steam nozzle into supply duct with static pressure exceeding 0.5 in. w.c.
• If remotely mounting TrueSTEAM, refer to the remote mount guide (69-2317) for further instructions.
• Do not install the humidifier where the ambient temperature is lower than 32°F (0°C) or higher than 104°F (40°C).
• Condensate pump must be rated at 212°F (100°C).
• Consult local plumbing codes for drain size, material, and maximum temperature allowed.
• If TrueSTEAM location is in or above finished space, install a drip pan with a wet switch under TrueSTEAM, the
water filter, and backflow preventer.
• Do not install the humidifier nozzle through wooden sidewalls (e.g., floor joist).
• The mounting area must be strong enough to support the humidifier’s weight when it is full of water (up to 15
lbs.).
• If the ducting has exposed insulated materials on the interior, ensure the nozzle extends beyond the insulation
by clearing 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 inches of clearance between the TrueSTEAM nozzle outlet and any interior duct to avoid
condensation forming.
• Mount TrueSTEAM where the nozzle outlet has a minimum of 24 inches of downstream open air space.
• Do not install in completely enclosed spaces, such as a cabinet or unventilated closet. Choose a location that is
well ventilated.
• Allow at least 1 foot clearance to ventilation holes in humidifier’s cover. Do not cover these holes. Covering them
can increase the internal operating temperature of the humidifier and shorten the humidifier’s life.
• Do not mount directly to duct board. Remote mount nozzle attachment allowed only with a Honeywell duct
board adapter kit.
• If used near a pool or spa, ensure the TrueSTEAM can not fall into the water or be splashed. Also, ensure the
TrueSTEAM is plugged into a GFI ground fault interrupt outlet.
