Serial Number______________________________________________Installation Date ________________________ Model _________________________________________________________________________________________ Introduction The Lifebreath HRV (Heat Recovery Ventilator) is designed to introduce fresh outdoor air into a building while exhausting an equal amount of stale indoor air. During the heating season, heat energy from the stale exhausting air is transferred to the fresh, incoming air via Lifebreath's patented aluminum core. -

Page 12: Remote Control Devices
Remote Control Devices Optional Main Control Features The amount of ventilation required in your home will fluctuate according to the activity level in the house. Higher activity levels require more ventilation. Main controls can be mounted in a central location of the home (i.e. beside the furnace thermostat) which will provide the user with complete control over their ventilation system from a convenient location. -
Page 13: Locating And Suspending The Hrv
Locating and Suspending the HRV Location Selection The HRV must be located in a heated space where it will be possible to conveniently service the unit. Typically the HRV would be located in the mechanical room or an area close to the outside wall where the weather hoods will be mounted. -
Page 14: Locating And Suspending The Rnc120D
Suspending the RNC120D Horizontal Installation Using full length hanger straps is recommended for vibration control, but can be shorter if required. Vertical Installation Suspending the RNC120D The hanging straps should be attached to the unit at the top end corners (mounting screws are already located on the HRV case). Securely fasten the other end of the straps to the ceiling making sure the UNIT IS LEVEL. -
Page 15: Drain Connection
Drain Connections Drain Connection (HRV Only) During a defrost cycle, the HRV may produce some condensation. This water should flow into a nearby drain, or be taken away by a condensate pump. CAUTION The HRV and all condensate lines must be installed in a space where the temperature is maintained above the freezing point or freeze protection must be provided. -
Page 16: Installation Methods
Installation Methods The Three Methods of Installation The three methods of installation for the HRV system are the Simplified, Partially Dedicated and Fully Dedicated Installations. Refer to the installation illustrations in this manual. Simplified Installations The Simplified Installation draws stale air from the cold air return duct of the air handler/furnace and introduces an equal amount of fresh air farther downstream into the cold air return. -

Page 23: Defrost Operation
Defrost Operation Recirculating Damper Defrost (4 port models) The recirculating damper defrost HRV has an electronically controlled damper defrost mechanism. The defrost timer is activated when the outside temperature drops below 27°F (- 3°C). A motor driven damper door mechanism closes off the supply air from outside allowing the exhaust air to recirculate through the unit. -

Normally the HRV/ERV would be balanced on high speed. If the HRV/ERV is connected to a forced air system, both systems should be set to run at the highest operational speed when balancing is performed. -

Page 33: Maintenance
Maintenance 1. Inspect Exterior Hoods at least once a month. Make sure exhaust and fresh air supply hoods are not blocked or restricted by leaves, grass, or snow. In winter, it is especially important to make sure snow is not blocking the hoods or that frost has not built up on the wire mesh (bird screen).
