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. 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.

12 HF Humidier

Electronically controlled FLOW-THRU model

This humidifier MUST be connected to a drain.

1 Assembling the unit

This unit is reversible, and can be mounted on either the hot air or return air ducts. 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.

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.

2 Cutting the opening

The humidifier is recommended to be installed on the cold air return,

but may be mounted to the warm air plenum as well. On whichever

duct you decide to install the humidifier, draw a level line for

placement of the template. If installing 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 opening in the plenum. Beware of sharp edges in the duct.

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.

9 Installing the electronic controller (HSA 055)

•

The HSA055 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, set the dip-switches, 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.

11 Installing the humidistat (DS00284) and the transformer (HEC025)

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.

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

• Attach the humidistat template (#2) on the duct.

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

• 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.

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.

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

• 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).

10 Wiring between the humidistat (DS00284), the transformer (HEC025)

and the electronic controller (HSA 055)

1- Push the two quick connectors on the humidistat terminals identified COM and NO.

2- Split the wire coming from the transformer in two, long enough to connect one end to the humidistat

(terminal COM) and the other one to the electronic controller (terminal 24VAC).

3- Use the separate piece of single wire to connect the other terminal 24VAC of the controller to the terminal NO.

4- Use the double wire to connect the valve to the two terminals (terminal VALVE) in the centre of the controller.

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.

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.

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

Install the 6" duct collar in a convenient location on the opposite duct with four screws (#8 x 3/8"). Using the gear clamp provided, fit the

flexible duct onto the collar and tighten gear clamp. 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 duct collar so it does not sag. Cut

the excess portion. Slide the flexible duct on the air take-off collar and secure it using the second gear clamp.

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.
