Consumer Information

A. To ensure quiet operation of the 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.

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.
