3 ER V Questions & Ans wers What is the difference between an HRV and an ERV? The core in an HRV (Heat Recovery Ventilator) transfers heat from one air stream to the other. This is called sensible heat. The term ERV (Energy Recovery Ventilator) is usually used to describe a unit with an enthalpic core that transfers moisture as well as heat fro[...]

13 Location f or Mounting The HRV/ER V must be located in a conditioned space where the surrounding air temperature does not fall below 60˚F (16˚C). The unit must be mounted level (horizontal). The warranty will be void if these conditions are not met. T ypically the HRV/ER V is positioned close to an outside wall or the roof to simplify the conn[...]

Outside W eatherhoods The weatherhoods must have built-in “bird” screen with 1/4 in (63.5 mm) minimum mesh to prevent birds and rodents from entering into the ductwork. Do not use smaller mesh as it will be very susceptible to plugging up. Gravity dampers at the vents must not be used as they will restrict air flow and often “seize up”. The[...]

15 F resh Air Supply S yst em The fresh air supply ductwork from the HRV/ER V may be directly connected to the return air duct of the forced air system. Check the air flow balance of the HRV/ER V with the air handler blower both “ON” and “OFF” to determine that it does not imbalance the HRV/ER V more than 10%. Also, it is advisable to inclu[...]

18 Electrical Connections It is recommended that a licensed electrician make all electrical connections. It is very important that the unit be properly grounded. It is recommended that a separate 15 amp/120 volt circuit be used. W ARNING: In order to prevent electric shock when cleaning or servicing the HRV/ER V , it is extremely important to confi[...]

It is necessary to have balanced air flows in an HRV/ERV. The volume of air brought in from the outside must equal the volume of air exhausted by the unit. If the air flows are not properly balanced, then; • The HRV/ERV may not operate at its maximum efficiency • A negative or positive air pressure may occur in the house • The unit may not de[...]

Servicing your HRV/ER V on a regular schedule will result in optimum operating efficiencies and prolonged life of the equipment. Due to numerous applications in which this equipment can be installed, it is difficult to predict servicing intervals. In certain situations where there is heavy smoke, servicing the equipment every one - two months may b[...]
