IMPORTANT - PLEASE READ THIS MANUAL BEFORE INSTALLING UNIT
CAUTION - Before installation, careful consideration must be given to how this system will operate if connected to any other piece of mechanical equip-
ment, i.e. a forced air furnace or air handler, operating at a higher static. After installation, the compatibility of the two pieces of equipment must be confirmed
by measuring the airflow’s of the Heat R

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. Our HRV’s are designed to run continuous or on in

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. Galvanized ducting from the HRV to the living areas in the house is recommended when

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 rec- ommended 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. In this method, the exhaust

1800 mm 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/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 hea
