3 Installation (cont'd)

3.3 Installing the Registers, Ductwork and Hoods

3.3.1 Registers

Refer to applicable building codes to plan where the stale air exhaust registers and fresh air distribution registers should be

installed. Below are some general recommendations.

Stale air exhaust registers:

• Install the stale air exhaust registers where the contaminants are produced: bathroom (up to 2), kitchen, living room, etc.

Position the registers as far from the stairway as possible and in such a way that the air circulates in all the lived-in spaces in

the house.

• If a register is installed in the kitchen, it must be located at least 4 feet away from the cooking applicances.

• Install the registers on an interior wall, 6 to 12 inches below the ceiling OR in the ceiling.

Fresh air distribution registers (Option 2 in 3.2.1):

• Install the fresh air distribution registers in bedrooms, dining rooms, living rooms and basement, if applicable.

• Keep in mind that the fresh air registers must be located as far as possible from the ERV stale air registers.

• Install the registers on an interior wall, 6 to 12 inches below the ceiling OR in the ceiling.

• If a register must be ﬂoor installed, direct the airﬂow up the wall.

WARNING

Never install a stale air exhaust register in a closed room where a combustion device operates, such as a gas

furnace, a gas water heater or a ﬁreplace.

3.3.2 Ductwork

• All units ports should be connected to 6” ducts, but can be connected to larger ducts using an appropriate transition.

• If you have to connect rigid ducts to the unit, use a short length (approximately 6”) of ﬂexible duct to avoid transmission of

vibrations. Use a tie wrap and foil tape to connect the ﬂexible duct to the port and to the rigid duct.

• Never use screws to connect rigid ducting to the ports.

Connecting insulated ﬂexible ducts to the ports:

1. Pull back the insulation to expose the ﬂexible duct.

2. Attach the ﬂexible duct to the port using a tie wrap; ensure tie wrap is tighten to its maximum strength.

3. Pull the insulation over the joint, then pull the vapor barrier (shaded part in illustrations below) over the insulation. Make sure

that the vapor barrier does not tear due to manipulation to avoid condensation within the ducts.

4. Apply foil tape to the joint, making an airtight seal. Avoid compressing the insulation when pulling the tape tightly around

the joint. Compressed insulation loses its R value and causes water dripping in cold climates due to condensation on the

exterior surface of the duct.

NOTE: If sealant mastic has to be used over the foil tape as an extra sealing layer, use water based mastic to ensure material

compatibility with the port.

WARNING

When performing duct connections, always use approved tools and materials. Respect all corresponding laws and

safety regulations. Please refer to your local building code.

CAUTION

If ducts have to go through an unconditioned space (e.g.: attic), always use insulated ducts to prevent condensation

formation inside and outside ducts, which could cause material damage and/or mold growth. Moreover, in zone B, if

fresh air to building duct and/or stale air from building duct goes/go through an unconditioned space, these ducts must

be buried with a minimum of R20 insulation in order to prevent heat recovery performance reduction and cooling of

the distributed fresh air to the living areas during winter operation. Also, the unit must be set to operate continuously

in cold conditions (below 50°F or 10ºC) if these ducts have to go through an unconditioned space in zones A and B.

Continuous air movement inside ducts will prevent condensation formation. The unit can be stopped temporarily for

maintenance and/or repair purposes in such conditions.

VR0003

Tandem VTYIK1 (USA) or 14690 (Canada)

CAUTION

If using a Tandem Transition, a backdraft damper must be installed on the stale air to outdoors duct. If this causes an

interruption in the duct insulation, insulation must be added around the backdraft damper to avoid condensation.

VR0021

Tandem V14695 (USA) or 14695 (Canada)

Make sure intake hood is located at least 10 feet away from any of the following (6 feet in Canada):

• Dryer exhaust, central vacuum vent

• Gas meter exhaust, gas barbecue-grill

• Any exhaust vents or chimney from a combustion source

• Garbage bin and any other source of contamination such as parking lots, streets

For multifamily buildings only:

Make sure exhaust hood is located at least 3 feet away from any of the following:

• Property lines

• Operable openings into buildings (door, window)

• Intake and exhaust hood(s) shall be protected with corrosion-resistant screens, louvers or grilles having openings not less than

1/4 inch and not larger than 1/2 inch.

• Install hood(s) at least at 18 inches away from the ground OR depth of expected snow accumulation, whichever is greater.

To minimize cross-contamination of exhausted stale air into the fresh air intake:

Single detached, attached homes and townhouses:

• Maintain a 6 feet minimum separation distance between outdoor air intake and exhaust hoods OR use an approved factory-built

intake/exhaust combination termination ﬁtting.

Multifamily buildings:

• Maintain a 10 feet (6 feet in Canada) minimum separation distance between outdoor air intake and exhaust hoods OR use an

approved factory-built intake/exhaust combination termination ﬁtting.

Ignoring these recommendations could signiﬁcantly degrade the quality of the incoming air which, in some cases, could result in

health consequences. In the event of a conﬂict between our recommendations and any local requirements, the latter shall have

priority.

9 Troubleshooting

If the unit does not work properly, reset the unit by removing power at service panel or unplugging it for one minute and then

restore power at service panel or replug the unit. If it still not working properly, refer to table below.

problems possible cAuses you should try this

1 Unit does not start.

• No power to power outlet or to

wires on power cable.

• Unit door not properly closed.

• PCB plastic holder tabs unclipped.

• Check the breaker in the distribution panel.

• ERVS100S-PC only: Test the power outlet with another

electrical device (e.g.: a lamp). If it does not work, call an

electrician.

• ERVS100S-HW and ERVS100S-HW-M only: Use a voltmeter

to check power cable wires. If there is no voltage detected,

call an electrician.

• Ensure the unit door is properly closed.

• Ensure the PCB plastic holder tabs are engaged in their

slots and the PCB is well seated on its holder.

LED blinks rapidly on

push button and unit

(motor error).

• Motor harness damaged or

misconnected.

• Defective PCB, motor assembly or

low speed capacitor.

• Check both motor harness connections, ensure that

connectors are connected to their appropriate places, the

wires are not damaged and connector pins are not corroded.

• Open the door and push on door switch spring to reset the

error and activate the unit self test during booting sequence.

Both motors must start in high speed for 10 seconds, then go

on low speed for 10 seconds. If both motors do not go on

high speed; replace the PCB.

• If one motor does not start on high speed, inverse both motors

connection and start again the self test; if the motor still not

start on high speed, replace the motor asembly and if the

problem is now on the other motor, replace the PCB.

• If both motors run in high but not in low speed, replace the low

speed capacitor. If only one motor runs in low speed, replace

the defective motor assembly.

LED blinks slowly on push

button and unit (RH and

temperature sensor error).

• RH and temperature sensor

misconnected.

• Defective RH and

temperature sensor.

• Check the sensor harness connection, ensure that connector

is connected to its appropriate place, the wires are not

damaged and connector pins are not corroded.

• Open the door and push on door switch spring to reset the

error and activate the unit self test during booting sequence.

Both motors must start in high speed for 10 seconds, then go

on low speed for 10 seconds. After that, the unit will test its

temperature and RH sensor. If the LED is still blinking slowly,

replace the defective RH and temperature sensor

4The wall control does not

work.

• Unit not compatible with control.

• The wires may be in reverse position.

• The wires may be misconnected.

• The wires may be broken.

• Defective wall control.

• Check table on page 2 for control compatibility.

• Ensure that the color coded wires have been connected to

their appropriate places.

• Ensure the wires are correctly connected.

• Inspect every wire and replace any damaged ones. If wires

are hidden into walls, test the control using a shorter wire.

• Replace the wall control.

Unit lets too much

moisture entering

the building during

ventilation.

• Unit backdraft damper misfunction.

• Wrong setting of RH limit.

• Check if the unit backdraft damper is closed when the unit

is off, if not, verify the orientation of the damper assemply

(“TOP” engraving on damper support must be on top),

verify if magnet is in place in the damper support, verify if

metal clip is in place on damper. Damper must open freely.

• Verify RH limit adjusment (factory setting is “N” for South and

humid climate), adjust the RH limit to “-” position to reduce

humidity limit of ventilation. Ventilation speed can be reduced

by changing mode allowing less moisture to enter the building.

6Unit stops ventilating too

often.

• Wrong setting of RH limit. • Verify RH limit adjusment (factory setting is “N” for South and

humid climate), adjust the RH limit to “+” position to increase

humidity limit of ventilation (allowing more ventilation time),

or set the RH limit to “OFF” position to deactivate the sensor.

WARNING

Risk of electric shocks. Electronic board connections must be checked by qualiﬁed personnel only.
