What If I Go On Vacation - Honeywell HM609 Operating Manual

What should I do at the end of the season?
The Steam Humidifier automatically shuts down when humidity is not needed for an extended period. After several
days of inactivity, the water tank will drain and remain empty until humidity is called again. This prevents water
from stagnating inside the tank. The Steam Humidifier will refill the tank with water and reset itself when your
control calls for humidity again.
Follow these maintenance steps at the end of the heating season. Doing this each year helps keep your Steam
Humidifier at peak efficiency:
WARNING! Electrocution Hazard.
During cleaning, the Steam Humidifier must be unplugged if cover is removed to prevent
120 VAC from being present in the coil and other tank components.
Clean the tank, following the procedure in "How do I clean the tank?" on pages 15 - 18. Cleaning the tank at the
end of the season ensures the Steam Humidifier will be ready to perform the next time your home needs humidity.
• What if I go on vacation? Even though the Steam Humidifier's water tank will drain automatically after several
days, Honeywell recommends shutting off the Steam Humidifier water supply and turning off the humidity
control for extended leaves. Upon return, turn on the water supply and reset the control to the desired setpoint.

Examine the water tank gasket. If the gasket
is cracked or split, it must be replaced before
re-attaching the water tank.
Clean out the ventilation holes in the
Steam Humidifier cover.
Clear the water drain tube connected to the solenoid
valve. Disconnect the hose and inspect for blockage,
then run hot tap water through the hose.
Check that the Steam Humidifier is still installed in a
level position.
