16 Operation of the HRV These Recirculating Models of HRV's will provide fresh clean air without sacrificing the savings of your energy conserving home. When outdoor air is required for pool room dehumidification, the aluminum cores of the HRV provide effective and efficient heat recovery exchange. Whether operating as an HRV or in recirculation mode, the energy efficient PSC blower motors provide reliable and cost effective operation. Operation: Humidity control is provided by an adjustable deh

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 be needed; whereas ventilating a meeting room for example for carbon dioxide may only need service every six months to a year. Motor Access to the motor is through the front service doors. Note heat exchanger core can be removed to provide more room. See CORE in this section. The m

We recommend aluminum foil tape. Stale Air Return System The stale air return system is used to draw air from the points in the building where the worst air quality problems occur. Balancing dampers and/or adjustable grilles are recommended on all return air lines which are used during installation to help balance the “draw” from different areas of the building. Alternately, the stale air may be drawn directly from the return air duct. When this system is used, the air handler’s blower must cons

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 Energy Recovery Ventilator (ERV), by using the balancing procedure in this manual It is always important to assess how the operation of any Energy Recovery Ventilator may interact with vented combustion equipment (ie. Gas Furnaces, Oil Furnaces, Wood Stoves, etc.) NEVER install an Energy Recovery Ventilator in

This is the factory default setting. Follow the instructions found on the HRV/ERV door to select desired mode and speed, or refer to the instructions found on the following page. Removing and relocating the Control Pad The Control Pad can be removed and installed in a remote location (100’ wire length max). The Control Pad can be installed in a 2x4 box with a “Decora” type cover plate or can be installed in the optional “Ventilation Dehumidistat” or “Air Sentry”. When the Control Pad is installe
