WELCOME

b Introduction

You are now the proud owner of an air exchanger. Carnes would like to thank you for purchasing this unit which, if you carefully follow the instructions in this guide, will provide you with years of comfort.

First ﬁll the product information section at the end of this guide. The data is necessary for any claim regarding the warranty.

c Air exchanger with heat recovery

This unit is specially designed to change the air in your home. This air exchanger will ensure continuous ventilation on request. In winter, it will dehumidify the ambient air to the level set on the control. Odors will also be exhausted and the life span of your house will be extended.

LOCATION

a Of the unit

The Carnes unit should be installed in an area where the temperature is always above the freezing point. The best location for the unit would minimize the total duct length and the number of elbows. The shorter the ducts and the fewer elbows there are, the higher the airﬂow will be.

b Of inlet grilles

The ambient air inlet grilles should be mounted close to areas with high humidity levels. Most of the time, they are located in the corridor between the kitchen and the washroom on the ground ﬂoor and close to the washroom in the basement. It should not be located in a room containing a combustion appliance like a furnace or a ﬁreplace. The grilles can be installed on the ceiling or a wall. Place the grille within 12” (30cm) of the ceiling.

c Of diffusers

The diffusers are normally installed in corridors as far from the ambient air intake as possible. This forces the air to circulate through most of the house.

The diffuser can be installed on a wall or on the ceiling. If it is located in an occupied area, we recommend mounting the diffuser on the ceil ing. This allows the fresh air to be mixed with the ambient air reaching the occupants, thus improving the comfort level during a cold winter day. A wall-mounted diffuser should be located within 12’’ (30 cm) of the ceiling.

d Of the humidity control

The control has to be installed where excess humidity is more likely to be detected. On the ground ﬂoor, this place is generally located between the kitchen and the bathroom.

If you wish to control the humidity level mainly in the basement you should install the control in this area. Avoid placing the humidistat in an area with stagnant air, for example behind a door.

The installation of the air exchanger must be in accordance with the applicable codes in your area.

INSTALLATION

a Of the unit

The unit is designed to be installed on a shelf or suspended to the structure. When the unit is on a shelf, it is necessary to have some vibration isolators under its casing to prevent the propagation of noise.

The air exchanger must be leveled horizontally. This is necessary to drain the condensation out of the unit. A drainage pipe should join the connection in the bottom of the casing to the building drainage system.

b Of the exhaust louver

The exhaust louver is installed through an exterior wall at 4’’ (10 cm) minimum above ground. Attach the intermediary sleeve to the plastic louver collar with a crew. Seal the gap between the sleeve and the wall.

c Of the inlet louver

The inlet louver is installed through an exterior wall, at more than 6’ (185 cm) from the exhaust louver and more than 18’’ (46 cm) above ground. Make sure the inlet louver is installed so the insulated vent duct, joining it to the cabinet, is as straight as possible.

d Of the humidity control

The control should be mounted on the wall, 5’ (150 cm) above the ﬂoor.

Drill a hole through the wall so you can pass a wire from the control to the unit. This wire contains 4 wires in different colors. Connect them to the wires coming out of the unit. Follow the color code. The wires are at 24V.

Attach the back part of the control to the wall. Install the plastic cover with the help of the ﬁxing screw and the control button.

INSTALLATION

e Of the ductwork

To maximize the air exchanger airﬂow, install the ducts as straight as possible. We recommend galvanized steel ducts for long ductwork be cause of their ease of cleaning and low ﬂow resistance.

You can run ducts through ﬂoors, ceilings, walls or closets and cover them thereafter with gypsum board. Ducts in unheated areas must be insulated. The last 3’ (m) of the exhaust duct adjacent to the exhaust louver should be insulated and covered with a vapor barrier.

Refer to page 18 to 25 to ﬁnd where the ducts can be connected to the unit. Slide end of ﬂexible duct over unit port. Wrap 2” (5cm) wide tape around duct.

If necessary, the gaps between ducts and walls or ceilings can be hidden with the rubber strips.

f Air balancing

The air supplied through the diffuser should be warmer than 54°F (12°C). Colder air would make people uncomfortable and create condensation on ducts surfaces. Balancing dampers should be installed in all the air exchanger ducts. They must be adjusted so the supplied air temperature is higher than the temperature stated above all year round.

The difference between the exhaust and supply airﬂow rates should be negligible (below 10%). Airﬂows balancing are especially important in houses with combustion appliances or in area where soil gas is deemed to be a problem. Use airﬂow measuring stations and a magnetic gage to measure the airﬂow rates.

The speed of each blower can be independently adjusted by turning the adjustment knob located on the top of the electrical box.
