Frequently Asked Questions - V180E75RT vänEE

What is the difference between an HRV and an ERV?

An HRV (heat recovery ventilator) uses a core that transfers heat from stale air to fresh air. An ERV (energy recovery ventilator) transfers both heat and moisture, improving comfort in summer and winter. The V180E75RT model is an ERV with a 75% efficiency core.

How do I install the unit?

The unit must be installed in a heated location (10-65 °C), near an exterior wall. It can be suspended from joists using the supplied chains or wall-mounted with brackets. The level must not exceed 1/4 in. Ensure easy access to filters and electrical compartment.

What operating modes are available?

Modes include: Standby (off), Min (minimum flow), Max (maximum flow), Intermittent (20 min at Min, 40 min off), Recirculation, Auto (adapts to outdoor temperature), Smart (autonomous management) and Turbo. Selection is made via the LCD screen or an optional wall control.

How do I perform auto-balancing?

Auto-balancing starts automatically at first power-up. After connecting the unit, follow the on-screen instructions: adjust max and min flows using +/- keys, then confirm with OK. Then select the installation configuration (T-1 to T-5) according to your duct network.

How often should I clean the filters?

Filters should be cleaned every 3 months. Remove dust with a vacuum, wash filters in warm soapy water (optionally add a little bleach), rinse and dry completely before reinstalling. Optional disposable filters should be replaced when dirty.

What should I do in case of error code E22 or E32?

These codes indicate insufficient airflow on the supply (E22) or exhaust (E32) side. Check that filters, grilles, and exterior hoods are not obstructed. Ensure ducts are not crushed. If the problem persists, reduce duct length or contact a professional installer.

How do I maintain the recovery core?

For HRV models: soak the core in warm soapy water, rinse and let dry. For ERV models: gently vacuum dust with a soft brush. Caution: do not soak the ERV core. Perform this maintenance annually, preferably in autumn.

Can I use an existing wall control?

Yes, the unit is compatible with several optional wall controls: Dehumidistat, Automatic, Advanced touch screen, and auxiliary 20-40-60. You can also use a central system thermostat with a ventilation output. Follow the wiring diagrams in the installation guide.

Can the unit operate in extreme cold?

Yes, the unit is designed for Canadian climates. It has an automatic defrost mode to prevent core icing. During extended absence, maintain indoor temperature above 18 °C and ensure exterior hoods are not blocked by snow.

Consumer Information

A. To ensure quiet operation of the ENERGY STAR certified H/ERV, each product model must be installed using sound attenuation techniques appropriate for the installation.

B. The way your heat/energy-recovery ventilator is installed can make a significant difference to the electrical energy you use. To minimize the electricity use of the heat/energy-recovery ventilator, a stand-alone fully ducted installation is recommended. If you choose a simplified installation that operates your furnace air handler for room-to-room ventilation, an electrically efficient furnace that has an electronically commutated (EC) variable speed blower motor will minimize your electrical energy consumption and operating cost.

C. Installation of a user-accessible control with your product model will improve comfort and may significantly reduce the product model's energy use.

2.2 INSTALLING THE DUCTWORK AND THE REGISTERS

WARNING

Never install a stale air exhaust register in a room where there is a combustion device, such as a furnace, gas water heater, fireplace or any appliance or equipment that can generate gaseous contaminants, or pollutants. The negative pressure this could create in the room may impair proper evacuation of the gas or pollutants, which may have severe health consequences.

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, if fresh air to building duct and/or stale air from building duct goes/go through an unconditioned space, the unit must be set to operate continuously in cold conditions (below 10°C/50°F). Continuous air movement inside ducts will prevent condensation formation. The unit can be stopped temporarily for maintenance and/or repair purposes in such conditions.

2.2.1 FULLY DUCTED SYSTEM (T-1) (THIS CONFIGURATION ALLOWS RECIRCULATION MODE TO OPERATE.)

STALE AIR FROM BUILDING:

• Install registers in areas where contaminants and humidity are produced: kitchen, bathrooms, laundry room, etc.
• Install registers on an interior wall, 6 to 12 inches away from the ceiling OR in the ceiling.
• Install the kitchen register at least 4 feet away from the range.
- Bathroom fans and range hoods can be used to better exhaust stale air.
• Homes with more than one level require at least one exhaust register at the highest level.

FRESH AIR TO BUILDING:

• Install registers in bedrooms, dining room, living room and basement.
• Install registers in the ceiling OR high on the walls with the airflow directed towards the ceiling.
- If a register must be installed in the floor, direct the airflow up the wall.

2.5 CONNECTING THE DUCTS TO THE UNIT

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.
• Do not use screws to connect the ducts or transitions to the ports so as not to interfere with ports inner dampers operation. A non-functioning damper could freeze the unit, which could cause damages.

INSULATED FLEXIBLE DUCTS

Use the following procedure to connect the insulated flexible ducts to the ports of the unit (exhaust to outside and fresh air from outside).

1. Expose the flexible duct by pulling back the insulation, and place it over the inner port ring.
2. Attach the flexible duct to the port using a tie wrap.
3. Seal the joint using duct tape.
4. Pull the insulation and vapor barrier over the joint, tuck them between the inner and outer rings of the double collar and fasten them in place using duct tape.

CAUTION

The vapor barrier should remain intact and free of cracks or openings. An opening could produce condensation inside or outside duct, which could cause material damage and/or mold growth in the long run.

VJ0157

TRANSITIONING TO 8-IN. DUCTS

If using 8-in. ducts, install 6-in. to 8-in. transitions on the ports, and secure using duct tape only. If rigid ducting is used, install a 12-in. section of flexible duct between the transition and the rigid ducting (see above). Rigid ducts

To prevent potential water leakage in cold side rigid ducting insulation, seal all rigid ducting joints with duct tape. To avoid transmission of vibrations, always use a 12-inch section of flexible duct to connect rigid ducts to the unit. To connect insulated rigid ducts to the unit (cold side) using insulated flexible ducts, follow instructions in section 2.4. To connect regular rigid ducts (warm side) to the unit using non-insulated flexible ducts, use a tie wrap.

NOTE: It is recommended to use 8" ducting instead of 6" ducting if required airflow is over 200 CFM and long run of ducting or high quantity of elbows is used. It will prevent having too high static pressure in the ducting.

2.5.1 DUCTS CONNECTION

IMPORTANT: Make sure to connect ducting as illustrated below to get airflows reading accuracy. Correct installation will also allow proper drainage of water that may accumulate in ducting.

CORRECT INSTALLATION

R = 3" minimum

VD0489

CAUTION

Ducting must not be too crushed. Otherwise, airflows reading accuracy will be affected.

CAUTION

Insulated ducts must have the same diameter as the ports to ensure proper drainage of water that may accumulate in ducts.
