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.
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”.
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%.

18 Electrical Connections It is recommended that a licensed electrician make all electrical connections. It is very important that the unit be properly grounded.
19 These models are equipped with a 3 speed control, low medium and high, as well as a lighted on/off switch and a 4 screw terminal strip. The terminal strip can be used to connect any low voltage device which will then jump the unit to high speed from whatever setting the speed control was on.

Oper ating the ControlAir 15 Plugging in the HRV/ERV energizes the unit. A self test function will be performed every time the HRV/ERV is energized (refer to “Self Test” for more details). After the self test has completed successfully the HRV/ERV will default to Speed 1.
22 T o select mode of oper ation for ControlAir 15 Model 500 Only Press and hold the fan selection button on the Control Pad. After 5 seconds the control will begin to cycle each mode holding each for 2 seconds. Release the button when the desired mode of operation is reached.
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.
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.
25 FIL TERS Open front service door to access the filters located in both supply and exhaust air streams. Note to remove and install filters, it may be easier to first remove the core(s). See CORE . The filters are designed to stop large particles from entering in the core.
