1 Assembling the unit

This unit is reversible. Although not mandatory, use on the hot air duct will improve performance. Find the best location and determine how
the humidifier will be installed. Select the top. Install and fasten the water diffuser, the long black plastic piece, with two screws #6 x 1/2"
inside the top of the humidifier. Install the electric valve (mounted on a plastic bracket) outside of the top of the humidifier. While supporting
the water diffuser with one hand, insert the plastic tube protruding from the valve into the hole in the middle of the top part of the humidifier
making sure that the plastic tubing is firmly seated in the hole of the water diffuser. Fasten the valve assembly to the unit with 4 screws # 6 x
1/2" (Kit #10). Finally, install the plastic pad retainer by snapping it in the hole located in the middle of the humidifier frame.

Warning : Always check that you are not about to cut or drill into any air conditioning or electrical accessory during installation.

2 Cutting the opening

The preferred installation is to mount the humidifier on the warm air
duct, though it can be mounted on either duct. On whichever duct you
choose to install the humidifier, you must draw a level line. If mounting
on the warm air duct, make sure the line is at least 4 inches above the
furnace housing for clearance of the drain tube.
Attach the template to the duct. Punch and drill the four corners for
the opening and the four fastening holes with a 3/32” drill. Remove
the template and complete the opening outline with a marker. Cut the

3 Installing the unit

Install the unit in the opening. Use the
four screws (#8 x 3/4") to attach the
humidifier body to the duct. 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. Then
fasten the unit completely.

opening in the plenum. Beware of sharp edges in the duct.

4 Installing the collar and the flex duct (HSA 130)

Place the 6" plastic collar in a convenient location on the opposite duct. Trace a circle for the opening, then cut the hole with tin snips.
Affix the collar with four screws (#8 x 1/2"). Slide the damper assembly into the side opening of the humidifier until it snaps. Make sure to
position the damper knob in front of the unit. Measure the required flex duct length to the plastic collar so it does not sag. Cut the excess
portion. Slide the flexible duct on the air take-off collar and secure it by inserting the plastic pins through
the vinyl in between two reinforcement wires.

5 Installing the drain tube (HPC 133)

Select a convenient drain location for running the drain tube. Before you connect the tube to the drain
fitting, slip the hose clamp over the tube. Push the drain tube (1/2" I.D.) over the drain fitting located at
the bottom of the unit and secure it in place with the hose clamp. Make sure the tube has no bends
and the water can flow easily in a straight manner to the drain without accumulating in the tube.

6 Installing the evaporator pad (EP 037)

The pad is enclosed in a plastic frame having molded markings that clearly indicates the bottom. Slide the pad into the bottom
part of the humidifier, the little bump at the top facing to you, then push the pad against the back opening of the humidifier. Lock the pad in place with the pad
retainer.

7 Installing the water supply valve (HSA 140) on a copper pipe

A plastic bag contains a brass valve and all the material required to install the water supply valve. Water is
taken from the nearest cold water pipe suitable for the supply valve installation. Do not install this on a
plastic pipe. Shut off the main water valve.

Brass

Note : Please make sure that the piercing pin is completely recessed into the valve body by turning the handle counter clockwise.
Do not use the saddle valve to adjust water flow. It is designed to be fully open or closed.

• Assemble one side of the top clamp to the bottom clamp with a screw and a nut.

• Make sure that the rubber gasket is in place over the piercing needle and position the valve assembly on the copper water line.

• Assemble the other side of the top clamp to the bottom clamp with the remaining screw and nut.

• Tighten the two screws so that the valve is firmly attached to the water pipe. The two sides of the clamp must be parallel.

8. Connecting the water supply tubing (HSA 170) to the water hammer absorber (HSA 215) and the valve (HSA 084)

• This water hammer absorber is connected to the electric valve in factory.

• Install the water supply tubing on the side of the water hammer absorber that has a compression
fitting to receive the supply tubing.

• Slip the brass compression nut onto the plastic supply tube, then the nylon sleeve with its most
tapered end towards the end of the tube. Finally, install a brass insert into the end of the
plastic tubing.

• Push the supply tube fully into the brass compression fitting. Tighten the brass compression nut
with small wrenches, without stripping the threads, using the double wrench method in order to
apply the torque on the fitting only.

• Then do the same operation at the other end of the supply tube and make the connection to the saddle valve previously installed on the copper supply pipe.

• Turn the valve handle completely clockwise until it stops. This will pierce the copper pipe and close the valve.

• This saddle valve is designed to be fully open or closed. Do not use it to adjust the water flow.
NOTE : The brass sleeve supplied with the brass valve Kit #10 is to be used only if the plastic tubing is replaced by copper tubing (not recommended).

9 Installing the electronic controller (HSA 044)

•

The HSA044 is factory set at NO TEMP, with settings for HIGH TEMP and LOW TEMP. The NO TEMP setting is used when the humidifier is supplied

power from the furnace. The unit will run as long as there is power AND the humidistat is calling for more humidity.

•

The LOW TEMP setting is used for furnaces that generate less heat, such as those with a heat pump. The unit may operate for a short while after the

furnace has stopped due to residual heat in the duct.

•

The HIGH TEMP setting is used for furnaces that generate more heat, typically oil or gas furnaces. You may have to try both settings to see which one is

right for you.

•

To choose the setting on the controller, place the jumper on the corresponding terminal pins, as shown on the controller. For HIGH and LOW settings, the controller must
be installed on the warm air duct with two screws (#8 x ½”). There are two lights on the controller: the green LED means there is power to the controller and the blue LED
cycles on as the valve opens. When switched ON by the humidistat, the controller opens the electric valve for approximately 2 seconds and then closes the valve for another
30, and so on. Please use Template #3 and drill the 3 holes.

NOTE : The quick connectors at the end of the double wire are not the same size.
The small ones go to the controller and the bigger ones to the electric valve.

11 Installing the humidistat (HSA 100) and the transformer (HSA 200)

This humidifier is supplied with a transformer that can be plugged in to any 120V electric outlet. The humidistat is a duct mounted type.
It is better to mount the humidistat on the RETURN duct because it will detect the air being returned to the furnace without being disturbed by a sudden
increase in moisture (as from a kitchen or bathroom). This will offer better humidity control.
Kit No. 4 contains all the material you need to install the humidistat.

Template

• The humidistat should be installed on a flat and vertical surface of the RETURN duct a minimum of 6 inches above the humidifier.

• Mark and drill the mounting holes and cut an opening for the humidistat.

• Run the control wires through an opening located at the bottom of the front panel of the humidistat.

• Hold the wires while you install the humidistat in the opening. Check that the metal of the duct neither touches the connections nor cuts the wire insulation. Then fasten the humidistat
to the duct. The humidistat mechanism is exposed in the duct. Temporarily install the control knob on the humidistat.

12 Humidifier Start-up.

Open the saddle valve, put the furnace power back on and start the furnace in a heating cycle. Set the humidistat at the maximum setting.
After a few ON/OFF cycles of the electric valve, you should see water flowing through the drain tube. Check that the water is evenly distributed by the water diffuser across the pad. Carefully check
that both ends of the water supply tube are firmly held in place by their respective compression fitting. After peeling off the backing, affix the faceplate to the cover of the humidistat and re-install the
control knob. Set the humidistat according to the recommended setting on the label. Check the system several times to make sure there is a free flow in the drain tube and there is no leak before
leaving the installation unattended. When everything is working fine, affix the adhesive nameplate on the humidifier cover.

Owner's Instructions for Electronically controlled FLOW-THRU Humidifier

Operating and Maintenance Tips - Warranty.

1. Principle of operation

• This humidifier uses a vertical evaporator pad, wetted by a pulsed water flow. Warm air is by-passed from

the warm air plenum and forced through the evaporator pad. Humid air is drawn back into the return duct.

• The pad is enclosed in a plastic frame with a marking that clearly indicates the bottom. It is designed to

retain water before it is evaporated. Any excess water is sent to the drain.

• All flow-through humidifiers improve performance and evaporative capacities if they are used

with constant blower operation. However, this unique pulse action model optimizes performance and

reduces water consumption by up to 80%.

• When the furnace is producing heat and the humidistat is calling for humidity, the electronic module

allows a controlled water flow on the evaporator pad. It opens the electric valve for an average of 2

seconds and then closes the valve for another 30 seconds, and so on, thus giving the time for the water

dispersed on the pad to be evaporated in the system, without wasting a lot of water which normally would

go directly to the drain. This is one of the main features of this model and it saves up to 80% of water

consumption. It is normal to have a bit of water flowing in the drain tube, though. This flushing-away

method removes the dissolved minerals that are left on the pad in a normal evaporation process before

they settle and dry up on parts that are in contact with water. The little water waste is a "rinse n' drain cycle".

2. Adjusting the humidity level in your home

• A relative humidity environment of 40% is recommended. Please refer to the table on the humidistat front

plate to help determine the proper level.

Outside Recommended

Temperature Setting

- 22°F (-30ºC) 15 %

- 13°F (-25ºC) 20 %

- 4°F (-20ºC) 25 %

+ 5°F (-15ºC) 30 %

+ 14°F (-10ºC) 35 %

above 23°F (-5ºC) 40 %

• At the beginning of the heating season it might take some time (a few days) to build up the humidity to

the comfortable level you want. Depending on the original dryness of the house, carpets, furniture and

wood will absorb moisture before you would really feel a dif ference.

• If your house remains unoccupied during the winter season, adjust the humidistat to a lower setpoint in

order to prevent condensation.

3. A few tips

• Do not use the supply valve (installed on the supply line) to regulate the water flow. This type of valve is

designed to be completely opened or closed.

• Do not allow the drain tube to fill with water in bends, elbows or kinks. Water could accumulate in them

and that could lead to deposit build-up. This could also create a back pressure preventing

the

water

from

flowing

naturally and cause an overflow.

4. Annual Maintenance

To replace the evaporator pad :

1- Unplug the transformer from the wall power supply.

2- Open the humidifier by removing the plastic screw on the side of the cover.

3- Unlock the evaporator pad by turning the little plastic retainer at the top of the pad.

4- Remove the old pad and replace it by a new one while checking the printed marking that clearly indicates

the bottom of the pad.

5- Lock the new pad in place.

6- Put the cover back and secure it with the plastic screw.

Note : Depending on the quality of water, it is recommended to replace the evaporator pad once per

heating season.

5. Summer season

• If the system is used in air conditioning during the summer, reduce the air volume going through the

humidifier by closing the air damper located on the side of the humidifier. The control button shows

the actual position of the damper.

• It is recommended to simply shut off the humidifier system :

1- Close the water supply valve.

2- Turn the humidistat knob to the "OFF" position.

3- Unplug the transformer.
