4. Humidifier location (Please see Fig. 1, 2 and 3)
•
This humidifier should be installed on the return duct (cold air). If for any reason you must install it on the supply duct, the
air pressure may lift the cover and you will have to attach it.
•
Identify the return duct and choose the duct side, which offers the best access for installation and maintenance.
•
The humidifier must be installed in such a way that if a leak occurs, the water could not cause any damage to the
property.
5. Preparing the humidifier
This humidifier is factory assembled with the air inlet located at the left side, thus the motor will be installed on the right side.
Everything is reversible, if necessary. However, if it is suitable as supplied, please go directly to
Step 6
(Installing the
humidifier).
If humidifier reversal is necessary, do the following (please see
Fig. 12
)
Lift the front of the water pan to disengage it from the sides of the humidifier and slide it out of the unit.
•
Remove the two screws (
12.1
) located at the top of the humidifier body.
•
Open the two sides (
12.2
) of the humidifier.
•
Bend the two sides in the opposite direction and finish with the top.
•
Put the two screws (
12.1
) back in place, taking care to not strip the plastic material.
6. Installing the humidifier (Please see Fig. 2, 3 and 4)
•
Please refer to the general view of a typical installation.
•
Shut off the furnace power.
•
Kit No. 1
contains all the material you need to install the humidifier body.
•
Choose the location of the template and make sure that a distance of approximately 14” between the furthest left vertical
line of the humidifier opening and the centre of the air take-off collar can be obtained. (Please see
Fig.2
).
•
This 14” dimension is given for a typical installation. Some installations may differ.
•
Apply the humidifier template (
#1
) on the return duct, level it and then attach it to the duct.
•
Starting from the vertical line of the opening (the one closest to the warm air duct), measure 14” and mark the centre of
the air take-off opening.
Warning: Always check that you are not about to cut or drill into any air conditioning or electrical accessory during
installation.
•
Center punch the four screw holes and the four corner holes through the template and pierce the duct with a 3/32” drill.
•
Remove the template. Join the four corner holes with a marker line. Make a starting hole and cut a rectangular opening
that will correspond to the back opening of the humidifier (7-3/4” x 6-1/2”).
•
Install the humidifier in the opening and attach it with the four screws #8 x 3/4”. The ribs around the humidifier back
opening must fit into the rectangular opening in the duct. Check that the humidifier body is level from side to side and from
back to front. Then fasten the humidifier to the duct.
•
Fasten the motor (
4.1
) to the opposite side of the air intake.
Kit No. 5
contains the motor (
4.1
) and two screws (
4.2
).
7. Installing the air take-off collar (Please see Fig. 2 and 10)
•
Center the air take-off collar on the point previously marked on the warm air duct.
•
Hold the collar (
2.3
) on the duct and mark the four fastening holes and the inside zone of the collar.
WARNING:
Always check that you are not about to cut or drill into any air conditioning or electrical accessory during
installation.
•
Drill the four fastening holes (3/32” dia).
•
Make a starting hole and cut a round opening for the air take-off collar.
•
Fasten the air take-off collar to the duct with screw #1 while making sure that the air damper is installed between the collar
and the air duct. The hole on the outer edge of the air damper should line up with hole #1 of the take-off collar, and the
finger pull protrudes outward (
Fig. 10A
).
•
Install screws #2 and #3.
•
Close the opening to approximately 50%.
•
Install screw #4 by piercing the damper, which will hold it in position.
Self-cleaning model:
Normally, when the warm air of the furnace flows through the humidifier, it evaporates the water contained in the foam pad, leaving
behind mineral deposits.
In the self-cleaning humidifier, the principle is to eliminate a small quantity of water containing a high level of minerals before filling
the unit with fresh water. The concentration of dissolved minerals will remain low, thus leaving few or no deposits on the parts that
contact the water. Environmentally, when compared to flow-through models, this unit is extremely friendly (as low as a few pans per
day) and the only thing you will have to do is to clean the water pan and the float with hot water every three months.
In one of the front corners of the pan will be the drain mechanism. Actuated by a paddle wheel, it opens a valve every eight turns of
the drum for one minute each time, thus allowing a very controlled water discharge.
NOTE:
The quantity of minerals dissolved in the water may vary from town to town, thus providing variable results.
