Healthy Climate HCWB3-17 Safety And Installation Instructions

SAFETY AND INSTALLATION INSTRUCTIONS FOR MANUAL HUMIDIFIER CONTROL FOR
HEALTHY CLIMATE HUMIDIFIER MODELS HCWB3-12, HCWB3-17 & HCWP3-18
ATTENTION INSTALLER: This product must be installed by a
qualified heating and air conditioning contractor. Failure to do
so could result in serious injury from electrical shock.
THESE INSTALLATION INSTRUCTIONS ARE FOR
THE MANUAL HUMIDIFIER CONTROL ONLY!
For humidifier installation, follow humidifier
installation instructions.
The Manual Humidifier Control is designed for low voltage service to
control humidification equipment. An increase in relative humidity (RH)
expands the nylon ribbon which opens the control switch to stop
operation of the humidifier. A decrease in RH reverses the process and
closes the control switch.
1. 120 volts may cause serious injury from electrical shock.
Disconnect electrical power to the furnace before starting
installation.
2. Sharp edges may cause serious injury from cuts. Use care
when cutting plenum openings and handling ductwork.
1. Do not set humidity higher than recommended. Condensation
damage may result.
2. Do not set humidity up to recommended levels if there is con-
densation on the inside of windows of any unheated living
space. Condensation damage may result.
3. Do not mount the Manual Humidifier Control on the supply
plenum or duct. The unit cannot withstand supply tempera-
tures and will malfunction.
4. Do not mount the Manual Humidifier Control downstream of
the bypass outlet. False humidity conditions will cause the
humidifier to operate incorrectly.
Read complete installation instructions and template before starting.
