2.6 PLANNING OF THE DUCTWORK

• Follow the instructions in Section 2.7 below to determine the appropriate duct diameters for your system. Do not use branch lines
smaller than 6”ø (152 mm) diameter.

• Do not use wall cavities as ducts.

• Keep it simple. Plan for a minimum of bends and joints.

• Do not ventilate crawl spaces or cold rooms.

• If the house has two floors or more, be sure to plan for at least one exhaust register at the highest lived-in level of the house.

2.7 CALCULATING THE DUCT SIZE

Use the table below to ensure that the ducts you intend to install will be carrying air flows around the recommended values.
Avoid installing ducts that will have to carry air flows near the maximum values and never install a duct if its airflow exceed
the maximum value.

NOTE: Examples 2.7.1 and 2.7.2 use imperial measures. The same calculation applies to metric measures.

2.7.1 EXAMPLE OF CALCULATION:

Problem: My installation requires two exhaust registers (one for the kitchen, one for the living room). I will connect these registers to

a main duct which will connect to the unit (high speed performance value of 320 cfm). What size of duct should I use for
the main exhaust duct and for the two end branches leading to the registers? (See illustration below.)

Solution: Simplified method.

(For a more detailed method of calculating duct size refer to the

ASHRAE or HRAI HANDBOOK).
Main duct:

Table on page 8 indicates a 8” Ø: recommended air flow: 260 cfm; maximum
air flow: 380 cfm.The high speed air flow of 320 cfm is close enough to the recommended
value (260) and far enough of the maximum value (380). Therefore a 8ӯ duct or larger
is an appropriate choice for the main e

xhaust duct.

End br

anches: Each end branch will have to transport an air flow of 160 cfm
(320 divided by 2). Table on page 8 indicates a 6ӯ: recommended air flow: 120 cfm;
maximum air flow: 180 cfm. The high speed air flow of 160 cfm is close enough to the
recommended value (120) and far enough of the maximum value (180). Therefore a 6ӯ
duct or larger is an appropriate choice for the 2 end br

anches.

2.7.2 EXAMPLE OF A DESIGN FOR A FULLY DUCTED SYSTEM FOR A UNIT HAVING A HIGH SPEED PERFORMANCE OF 320 CFM.

CAUTION

Do not attempt to recover the exhaust air from a dryer or a range hood. This would cause clogging of the filters.

2.8 INSTALLING DUCTWORK AND REGISTERS

2.8.1 STAND ALONE SYSTEM

Stale air exhaust ductwork

• Install the stale air exhaust registers in the areas where the contaminants are produced: kitchen, living room, etc. Position the
register as f

ar from the stairway as possible and in such a way that the air circulates in all the lived-in spaces in the house.

NOTE: Never install a stale air exhaust register in a bathroom.

• If a register is installed in the kitchen, it must be located at least 4 feet (1.2 m) from the range.

• Install the registers 6 to 12 inches (152 to 305 mm) from the ceiling on an interior wall OR install it in the ceiling.

• Use the provided red sticker dots to identify the duct.

Filtered air distribution ductwork

• Install the filtered air distribution registers in the lowest level to ensure the greatest possible air circulation. Keep in mind that the
filtered air registers must be located as far as possible from the stale air registers.

• Install the register in the ceiling OR 6 to 12 inches (152 to 305 mm) from the ceiling on an interior wall. The duct length should be at
least 15’ (4.6 m). (The filtered air will then flow through the room and mix with room air, ensuring a continuous recirculating airflow.)

• Use the provided blue sticker dots to identify the duct.

How to connect the flexible duct to the unit ports

• Each port is identified on top of the unit (see illustrations below). Attach the filtered air to building duct to its corresponding port,
using tie wrap (1). Then, attach the exhaust air from building duct to the other port (2).

NOTE: Use a 8’’ insulated duct if the duct will have to go through extreme temperature (e.g.: in northern area, not heated attic in

winter or attic not cooled in southern area). Also. if you plan to stop the unit for more than 12 hours, we recommend to cover
the duct with R12 insulation.

3.6 PLANNING OF THE DUCTWORK

• Follow the instructions in Section 3.7 below to determine the appropriate duct diameters for your system. Do not use branch lines
smaller than 4”ø (102 mm) diameter.

• Do not use wall cavities as ducts.

• Keep it simple. Plan for a minimum of bends and joints.

• Do not ventilate crawl spaces or cold rooms.

• If the house has two floors or more, be sure to plan for at least one exhaust register at the highest lived-in level of the house.

• Keep the length of insulated ducts to a minimum.

3.7 CALCULATING THE DUCT SIZE

Use the table below to ensure that the ducts you intend to install will be carrying air flows around the recommended values.
Avoid installing ducts that will have to carry air flows near the maximum values and never install a duct if its airflow exceed
the maximum value.

NOTE: Examples 3.7.1 and 3.7.2 use imperial measures. The same calculation applies to metric measures.

3.7.1 EXAMPLE OF CALCULATION:

Problem: My installation requires two exhaust registers (one for the kitchen, one for the bathroom). I will connect these registers to

a main duct which will connect to the unit (high speed performance value of 90 cfm). What size of duct should I use for the
main exhaust duct and for the two end branches leading to the registers? (See illustration below.)

Solution: Simplified method.

(For a more detailed method of calculating duct size refer to the

ASHRAE or HRAI HANDBOOK).
Main duct:

Table above indicates a 5” Ø duct: recommended air flow: 75 cfm; maximum
air flow: 110 cfm.The high speed air flow of 90 cfm is close enough to the recommended
value (75) and under the maximum value (110). Therefore a 5ӯ duct or larger is an
appropriate choice for the main e

xhaust duct.

End branches: Each end branch will have to transport an air flow of 45 cfm (90 divided
by 2). Table above indicates a 4ӯ duct: recommended air flow: 40 cfm; maximum air
flow: 60 cfm. The high speed air flow of 45 cfm is close enough to the recommended
value (40) and far enough away from the maximum value (60). Therefore a 4ӯ duct or
larger is an appropriate choice for the 2 end br

anches.

3. THH 1.0 UNIT INSTALLATION (CONT’D)

CAUTION

Do not attempt to recover the exhaust air from a dryer or a range hood. This would cause clogging of the filters
and the heat recovery core.

6. BALANCING PROCEDURE (THH 1.0 ONLY)

6.1 WHAT YOU NEED TO BALANCE THE UNIT

• A magnehelic gauge capable of measuring 0 to 0.5 inches water gauge (0 to 125 Pa)
and 2 plastic tubes.

• Two flow collars (the size will vary depending of duct diameter).

Flow collar

6.2 PRELIMINARY STAGES FOR BALANCING THE UNIT

Seal all the unit ductwork with tape. Close all windows and doors. Turn off all exhaust devices such as: range hoods, dryers and
bathroom fans. Make sure balancing dampers are fully open

(F and G in figure below).

Choose an appropriate location for the 2 flow collars according to figure below:

• On the exhaust air duct (first measuring location, A)

• On the fresh/filtered air distribution duct (second measuring location, B)

• At least 36” (914 mm) away from the unit; at least 12” (304 mm) before or after 90° elbow and at least 12” (304 mm) away from
a register.

• At least 12” (304 mm) away a from a balancing damper (F and G in figure below).

(

OR

G

(

(

)

Insert the flow collars in the ducts at each location (A et B on figure above). Make sure their arrows are pointing in the direction of the
airflow. Tape collars in place temporarily.

6.3 INSTALLATION OF FLOW COLLAR

6.4 BALANCING PROCEDURE

1. Set the unit to high speed.
Make sure that the furnace blower is ON if the installation is in any way connected to the ductwork of the cold air return. If not leave
furnace blower OFF.

2. Place the magnehelic gauge on a level surface and adjust it to zero.

3. Connect tubing from gauge to flow collar in exhaust air stream (location A in illustration above). Be

sure to connect the tubes to their appropriate high / low fitting. If the gauge reading drops to below

zero, reverse the tubing connections.

NOTE: It is better to start with the exhaust air flow reading because the exhaust typically has more

restriction than the fresh air, especially in cases of stand alone and central draw point installations.

Hold or place the magnehelic gauge upright and level. Record the reading.

4. Move tubing to the other side of the unit (location B in illustration above and note reading. Adjust the fresh
air balancing damper F until the reading at B is approximately the same as the reading at A. If the reading
at B is less than the reading at A then go back and adjust the exhaust balancing damper G to equal the
fresh air flow.

5. Remove flow collars and reconnect the duct, then, seal with duct tape. Write the required airflow information on a label and stick it
near the unit for future reference: (date, maximum speed airflows, your name and phone number and business address).
NOTES:

• Most flow collar kits provide a conversion chart situated on the collar which enables you to convert magnehelic gauge readings to
equivalent cfm values.

• A difference of ± 10 cfm ( ± 0.015 inches water gauge) between the 2 readings isconsidered balanced.

• If you are using only one flow collar, then, after completing the first reading, transfer this measuring device to the other side of the
unit and take the second reading.

7. MAINTENANCE

7.1 SEMI-ANNUAL MAINTENANCE (ESSENTIAL)

If your unit is equipped with an optionnal wall control (04862 / 05439 or 04391 / 05536) you should perform this maintenance when the
Filter Maintenance light is flashing. Otherwise, this maintenance must be performed every 6 months to ensure your unit proper operation
for years to come. Follow these steps:

1. Turn switch knob to OFF to unlock the door.

2. Unlatch the door and open it. Clean the inner side of the door with a clean damp cloth, then wipe with a dry one.

3. Slide out the heat recovery module (THH 1.0 units only) and the filter cartridge from the unit.

1) Heat recovery module 2) Tabs

NOTE: To remove the filter cartridge, pull on its tabs (2).

4. Using your thumbs, push on the prefilter side to disengage it from the filter cartridge. Then, slide it out of the filter cartridge and
discard it. Install the new prefilter by reversing this operation.

1) Filter cartridge

2) Prefilter

5. Clean the inside walls of the unit with a clean damp cloth, then wipe with a dry one.

WARNING

Risk of electrical shocks. Before performing any maintenance or servicing, always disconnect the unit from its
power source.

7.1 SEMI-ANNUAL MAINTENANCE (ESSENTIAL) (CONT’D)

For

THH unit only

Wash the 2 core filters under hot water with mild soap. Soak the core in a solution
of warm water and mild soap. Rinse the core filters and the core thoroughly and
let dry before reinstalling them in the unit.

1) Core filters

2) Core

NOTE: Make sure the damper spring (1) is still inside the left front port opening before

reinstalling the recovery module.

1) Damper spring

6. Close the door, close the latches and turn ON the switch knob to its previous position.

7. If your unit is equipped with a wall control (04862 / 05439 or 04391 / 05536), reset the filter maintenance indicator by inserting a

small rod (eg: paper clip end) into the reset filter hole of the optional wall control. Press lightly until the Filter Maintenance indicator
light turns off.

7.2 ANNUAL MAINTENANCE (ESSENTIAL)

If your unit is equipped with an optional wall control (04862 / 05439 or 04391 / 05536) you should perform this maintenance when the
Filter Maintenance light stays ON. Otherwise, this maintenance must be performed once a year to ensure proper operation of your
unit for years to come. Proceed as the Semi-annual Maintenance (Section 7.1), but instead of replacing the prefilter (point 4), discard
the complete HEPA Filter cartridge (including prefilter). Install a new HEPA filter cartridge (or a new pleated filter cartridge) with a new
prefilter on it.

7.3 MASTER RESET

Use the master reset only if you replace the filters before the annual maintenance indicator is on. By inserting a small rod (eg: paper clip
end) for 5 seconds or more into the reset filter hole of the optional wall control, a master reset will be done and both biannual and annual
maintenance filter are reset.

04862 / 05439 Control

: The filter maintenance indicator will flash 1/4 second if the wall control is on Normal or Boost position.

04391 / 05536 Control: If the wall control is in ”Off” position, “Fresh air” light indicator will flash for 1 second. If the wall control is in

”Normal” or “Boost” position, the unit motor, the “Fresh air” light indicator and speed light indicator (“Normal” or

“Boost”) will turn off for 3 seconds. If the wall control is in ”Recirculation” position, the “Recirculation” light indicator
and the unit motor will turn off for 3 seconds.
