PERIODIC MAINTENANCE
NOTE: Periodic inspection and preventative maintenance
of your total heating system is important for efficient and
safe operation. Your heating contractor can service your
humidifier when he services the HVAC system.
The distribution tray above the water panel should be
inspected annually and cleaned of excess mineral deposits.

If your humidifier is equipped with a Digital Humidifier
Control with water panel change indicator, after replacing
the water panel, turn the control knob to the “Test/Reset”
position until the “Humidifier On” light blinks to reset its
timer. (Blower must be operating and HVAC calling for heat.)
Be sure to turn the control knob back to it’s original setting. If
the “Humidifier On” light continues to blink, your humidifier
is in Test mode.
DO NOT LEAVE THE CONTROL IN TEST
MODE OR HUMIDIFIER WILL NOT OPERATE.
REQUIRED MAINTENANCE
WARNING
ELECTRICAL SHOCK HAZARD. Can cause injury or
death. Disconnect all electrical power supplies before
servicing. Turn the Humidifier Control to “OFF” or the
lowest setting before servicing.
1. Note Humidifier Control setting and turn dial to the “OFF”
position.
2. Disconnect electrical power and turn off water supply.
3. Unlatch humidifier front cover assembly (1) from base
assembly (2) at the bottom of the cover, lift, and set aside.
4. Pull out the Water Panel evaporative assembly (3) by
grasping at the top and tipping out.
5. Unsnap the distribution tray (4) from the scale control
insert (7). Lightly scrape out or brush off any mineral deposits,
being careful not to stretch or loosen the synthetic fabric
liner. Soaking the tray in vinegar or a lime-removing agent
is helpful when trying to remove stubborn mineral deposits.
6. Slide the water panel evaporator (6) out from the scale
control insert (7) and dispose of the water panel. Clean the
scale control insert of mineral deposits. Replace the water
panel evaporator (Stock No. 35) with a new EnviroAire IAQ
water panel. Slide the water panel evaporator back into the
scale control insert with the colored spot up and snap the
distribution tray (4) back into place.
7. Inspect the plastic feed tube by gently flexing it and
looking for cracks or signs of wear. Replace tube if it is
cracked, brittle, or has been damaged.
8. Reinstall the water panel evaporative assembly (3) into
the humidifier by fitting its drain into the round receptacle at
the base of the humidifier. Push the assembly in at the top
between the retaining ribs that hold the assembly in place in
a vertical position.
