OPERATION An Energy Recovery Ventilator (ERV) is designed to bring in fresh air into the building while exhausting an equal amount of stale air. During colder months, utilizing the heat recovered from the stale air before it is exhausted outdoors warms the cold fresh air. At the same time, humidity contained indoors is transferred back to the incoming fresh and dried air.
OPERATION (CONT'D) OPTIONAL REMOTE CONTROLS PRACTICAL TIPS To avoid window condensation: • If a dehumidistat or EDF control is installed, the humidity setting should be raised to its highest setting (e.g. 99% on EDF) when using an ERV during warm and humid months. Otherwise, the ERV may stay on HIGH speed, bringing in more humid air indoors. Dehumidistat I - The wall mount dehumidistat monitors the humidity level in the area it is installed.
OPERATION (CONT'D) OPTIONAL INTELLITEK CONTROL DIGITAL HYGROMETER DISPLAY Shows Indoor Humidity Level This control will not read below 29% RH OVERRIDE TIMER When pressed, unit will provide high speed ventilation for 15 minute period. Once the time elapsed the unit will return to its normal function. To move from one time to the other, continue pressing the timer button until you reach the desired time.
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. LOCATION The ERV should be located in a conditioned space where it will be possible to conveniently service the unit. Typically the ERV would be located in the mechanical room or an area close to the outside wall where the weatherhoods will be mounted.
INSTALLING DUCTS GOING TO / FROM OUTSIDE PRACTICAL TIPS A well designed and installed ducting system will allow the ERV to operate at its maximum efficiency. Always try to keep duct runs as short and straight as possible. See Installation Diagrams for installation examples. • 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. The furnace or air handler return duct may be also used to exhaust from. In this method, the exhaust air is not ducted back from bathrooms, kitchens, etc to the ERV with “dedicated lines”.
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 ERV 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. - Energy 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 3 Adjust the damper until you reach the desired velocity. (damper should be 18” from grid) 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. 2 Before taking the reading, make sure that the magnehelic gauge is level and at 0.
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. ERV out of balance Balance ERV 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.
