Like your heating system and air conditioning
unit, periodic maintenance and cleaning are
required to ensure the safe and efficient
operation of your humidifier.
To improve the efficiency of your humidifier, and
to reduce the possibility of a health hazard, it is
recommended that you take the following
precautions:
• Follow the manufacturer’s recommended
cleaning and maintenance instructions.
• The amount of minerals and other impurities
in a water source can vary greatly, therefore
the frequency of cleaning the humidifier
also varies.
• During the heating season, check for film or
scale build-up on the atomizing nozzle and
drip sleeve on a monthly basis. Establish a
proper cleaning schedule to ensure the
efficiency of the humidifier.
• At the end of the winter humidification
season, drain and thoroughly clean the
humidifier.
Note:
The necessity to clean your
humidifier is substantially the
result of impurities coming in
through your water supply
which feeds the humidifier.
Other household dust,
containing biological and
microbial contaminants can
find its way into the air
handling system and
ultimately, the humidifier.
The humidifier is not the
source of these impurities.
Maintenance
To check for leaks:
1. Turn the furnace and
humidistat on and ensure
that the humidifier has
operated for at least (1)
minute.
2. Remove the screws from
the top of the unit and
check the nozzle for
leakage.
3. If there is no leakage,
return the unit to its
original position and secure
with screws.
4. After completing the
cleaning, operate the
solenoid to be sure it is
operating properly.
To inspect and clean the unit:
1. Turn the power to the furnace OFF.
2. Turn the humidistat to the OFF position.
3. Turn the water off at the saddle valve and
remove the water line compression nut
from the humidifier.
4. With the open end of the water line
directed into a bucket or pan, turn on the
water at the saddle valve to void the water
line of any debris or particulates.
5. Remove the screws from the top of the unit
and swing the unit down to gain access to
the nozzle.
6. Remove the drip sleeve from around the
nozzle and clean in a 50/50 solution of
vinegar and water.
7. Carefully remove the nozzle from the
adapter.
8. Replace the spray nozzle with one of the
same size and capacity as initially provided
with the unit. Tighten securely and replace
the drip sleeve around the nozzle.
9. Swing the unit into place and fasten with
screws.
10. Restore the water supply to the humidifier
by reversing step 3.
