Warnings and cautions
WARNING
Disconnect electrical power
Disconnect electrical power before installing supply wiring or performing service or maintenance procedures on any
part of the humidification system. Failure to disconnect electrical power could result in fire, electrical shock, and other
hazardous conditions. These hazardous conditions could cause property damage, personal injury, or death.
Contact with energized circuits can cause property damage, severe personal injury, or death as a result of electrical shock
or fire. Do not remove humidifier electrical panel cover, heater terminal cover, or subpanel access panels until electrical
power is disconnected.
Follow the shutdown procedure on page 52 before performing service or maintenance procedures on any part of the
system.
Electric shock hazard
• If the humidifier starts up responding to a call for humidity during maintenance, severe bodily injury or death from
electric shock could occur. To prevent such start-up, follow the procedure below before performing service or
maintenance procedures on this humidifier (after the tank has cooled down and drained):
1. Use Vapor-logic
®
display to change control mode to Standby.
2. Shut off all electrical power to humidifier using field-installed fused disconnect, and lock all power disconnect
switches in OFF position.
3. Close field-installed manual water supply shut-off valve.
• The appliance is not to be used by persons (including children) with reduced physical sensory or mental capabilities,
or lack of experience and knowledge, unless they have been given supervision or instruction.
• Children being supervised not to play with the appliance.
• Thermal cut-out component is critical to the safety of this equipment: use only DriSteem replacement part.
CAUTION
Hot discharge water
Discharge water can be as hot as 212 °F (100 °C) and can damage some drain plumbing.
To prevent such damage from humidifiers with water tempering disabled, allow the tank to cool before draining.
Humidifiers equipped using internal water tempering or an external water tempering device need fresh make-up water in order to
function properly. Make sure the water supply to the humidifier remains open during draining.
Excessive supply water pressure
Supply water pressure greater than 80 psi (550 kPa) can cause the humidifier to overflow.
