OPERATION A Heat Recovery Ventilator (HRV) is designed to bring fresh air into a building while exhausting an equal amount of stale air. During the winter months, the incoming cold fresh air is warmed by utilizing the heat recovered from the stale air before it is exhausted to the outdoors. During summer months when the indoor space is air conditioned, the HRV will help in cooling the incoming fresh air with the stale air that is being exhausted.
OPERATION (CONT'D) OPTIONAL REMOTE CONTROLS PRACTICAL TIPS To avoid window condensation: • It is not necessary to change the humidity control every day. Monitor the average weekly temperature or experiment with various settings until you find a level that is comfortable for you. Adjust the control when needed. NOTE: A dehumidistat is ideal for use in energy efficient houses where indoor humidity (during the heating season) is higher than outdoor levels.
INSTALLATION PRACTICAL TIPS • Install the unit close to the outside wall on which the supply and exhaust hoods will be mounted. • Have a nearby power supply 120 Volts, 60Hz. • Have the possibility of mounting the unit to supporting beams. • Mount the unit as level as possible in order to allow proper condensate drainage. LOCATION The HRV must be located in a heated space where it will be possible to conveniently service the unit.
INSTALLING DUCTS GOING TO / FROM OUTSIDE A well designed and installed ducting system will allow the HRV to operate at its maximum efficiency. Always try to keep duct runs as short and straight as possible. See Installation Diagrams for installation examples. PRACTICAL TIPS • Decide where your intake and exhaust hoods will be located.
INSTALLING DUCTS TO / FROM INSIDE To maximize airflow in the ductwork system, all ducts should be kept short and have as few bends or elbows as possible. Forty-five degree are preferred to 90º elbows. Use “Y” tees instead of 90º elbows whenever possible. All duct joints must be fastened with screws or duct sealant and wrapped with a quality duct tape to prevent leakage. Aluminum foil duct tape is recommended.
INSTALLING DUCTS TO / FROM INSIDE (CONT'D) Exhaust Air Ducting The stale air exhaust system is used to draw air from the points in the house where the worst air quality problems occur. It is recommended that return air ducts be installed in the bathroom, kitchen, and laundry room. Additional return air ducts from strategic locations (i.e. greenhouse, atrium, swimming pool, sauna, etc.) may be installed. The furnace return duct may be also used to exhaust from.
INSTALLATION EXAMPLES It is the responsibility of the installer to ensure all ductwork is sized and installed as designed to ensure the system will perform as intended. All air movement devices have a performance curve. The amount of air (CFM) that an HRV will deliver is directly related to the total external static pressure (E.S.P.) of the system. Static pressure is a measure of resistance imposed on the blower by length of duct work/number of fittings used in duct work, duct heater etc.

AIR FLOW BALANCING CAUTION • If the unit’s airflows are not properly balanced... - The unit may not operate at it’s maximum efficiency. - Heat recovery core damage may occur. - The unit’s use could cause negative or positive pressure in your home causing cold air to enter or other combustible equipment to backdraft. - The unit may not defrost properly.
AIR FLOW BALANCING (CONT'D) AIRFLOW STATION (GRID) METHOD B 1 For this flow measuring station, cut the duct and place the flow measuring station between each station. Make sure that the flow measuring station’s air direction arrow points in the direction of the airflow. Secure the flow measuring station with duct tape. 18” (457 mm) 18” (457 mm) Measure here Measure here 22 2 Before taking the reading, make sure that the magnehelic gauge is level and at 0.
MAINTENANCE CAUTION MAKE SURE UNIT IS UNPLUGGED BEFORE ATTEMPTING ANY MAINTENANCE WORK The following components should also be inspected regularly and well maintained. PRACTICAL TIPS • To prevent electrical shock, check that the unit is unplugged before doing any repairs or maintenance. • A yearly inspection is recommended to ensure the efficiency and troublefree use of your system. Run through the system and verify the different operating modes.
TROUBLESHOOTING Problem Causes Solutions Air is too dry Dehumidistat control is set too low Increase the desired level of humidity. Change ventilation mode from continuous mode to standby. HRV out of balance Balance HRV Dehumidistat control is set too high Reduce the desired level of humidity. Combine this step with use of continuous exchange mode. Sudden change in temperature Wait until outside temperature stabilizes (winter). Heating will also improve situation.
