You benefit from a lifetime warranty onthe core, and a 5 year warranty on allother components. So you can breathe easy. SafetyConsiderations for HRV 1. Read entire manual before attempting to install the unit. 2. Always determine how the operation of the unit will interact with Combustion Appliances (i.e. Gasfurnace, Wood stoves, Oil furnace…) 3. Never install a unit in situations where normal operation, lack of operation or partial failure may result inbackdrafting or improper functioning of Combustion Appliances. 4. Keep the units’ Fresh air intake a safedistance from any potential source ofcontamination, which may causehealth problems.

Room Count Calculation Ventilation Needs installation LIVING SPACE Number of Rooms CFM (L/s) CFM Required Master Bedroom x 20 cfm (10 L/s) = With Basement x 20 cfm (10 L/s) How much fresh air do I need? Good air = quality is based in part on the capacity of the home’s ventilation system. Usually, the HRV’s capacity is measured in CFM (Cubic Feet per Minutes) or L/s (Liters per Seconds) of fresh air being distributed in the living space. The Room Count Calculation or the Air Change per Hour Method shows you how to determine your ventilation needs. Air Volume Needed installation Without Basement Single Bedroom Living Room Dinning Room Family Room Recreation Room Other Kitchen x 10 cfm (5 L/s) = Bathroom x 10 cfm (5 L/s) = Laundry Room x 10 cfm (5 L/s) = Utility Room x 10 cfm (5 L/s) = x 10 cfm (5 L/s) = x 10 cfm (5 L/s) = x 10 cfm (5 L/s) = x 10 cfm (5 L/s) = x 10 cfm (5 L/s) = x 10 cfm (5 L/s) = TOTAL ventilation requirement (add last column) = 1 CFM = 0.47189 L/s 1 L/s = 3.6 m3/hr B. Air Change per Hour Method TOTAL cu ft X 0.3 per hr = total Take total and divide by 60 to get CFM Example: 25’ x 40’ house with basement 1,000 sq. ft. x 8’ high x 2 (1st floor = basement)= 16,000 cu. ft. 16,000 sq. ft. x 0.3 ACH = 4,800 cu. ft. 4,800 sq. ft. / 60 Minutes = 80 CFM 80 CFM is your ventilation needs 2. Typical Installation In a typical installation there must be an adequate air volume passing through the unit in proportion of the pressure from VENTILATION PERFORMANCE - MODEL SH Supply ReturnSupply Return the heating system. 0.25 0.25 60 70 80 90 100 Ft3/min. of HRV (Exhaust) 60 70 80 90 100 Ft3/min. of HRV (Fresh Air Intake) Exemple: On the warm side*, the air vol ume needed is based on a 26’ rigid duct.

Typical Installation (continued) 3. Typical Installation (continued) Exhaust from the Exhaust from supply and supply in return supply and supplyin return installation Make sure that the Supply air from HRV isat least 3 feet from the forced air system. Can be different from a region to another. You should check with your localcode or the forced air system’s manufacturer. Forced Air System 6’ 18” Heat Recovery 3’ FOR MINIMUM DISTANCE BETWEEN RETURN AND FORCED AIR SYSTEM Check with your local building codes and forced air system manufacturer Airflow Direction installation Check the airflow direction before startingthe unit. If the airflow is not as indicated, flip the core to the appropriate side. Note: To install the core unit accordigly towith the airflow, locate the four arrows on the core decal and read the directions.
