The Benefits of ERVs Energy Recovery Ventilators (ERV) are designed to supply fresh air to a building while exhausting an equal amount of stale air from the building. An energy savings is experienced during the process by reducing the heating (or cooling) requirements. ERV - Enthalpic Paper Core An ERV is designed for use in warm humid areas with heavy air conditioning use.

The Ductwork System A properly designed ducting system will allow the ERV to operate at its maximum efficiency. (Air flow will be restricted by undersized ducting, use of too many elbows, tees, bends, etc.). Always try to keep duct runs as short and straight as possible. NOTE: Fully insulated ducting with an integral vapor barrier must be used on all runs passing through unheated areas in order to avoid condensation problems and energy losses from the air steams.
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 constantly operate.
The Integrated HVAC System The ERV has become an integral component of the HVAC system. Figure A shows an ERV unit providing fresh air directly to the return air plenum of a rooftop heat/cool unit. In the balanced airflow system, the ERV exhaust removes stale room air (eg. from lunch room, storage or copy area) and returns to the space an equal amount of fresh outdoor air, making the use of an economizer obsolete in conjunction with an ERV. Many buildings have ceiling return air plenum as in Figure B.
Electrical Connections Electrical Connections It is recommended that a licensed electrician make all electrical connections. It is very important that the unit be properly grounded. The circuit must be sized to handle the F.L.A. indicated on the name tag for the circuit. WARNING: Verify the polarity of the power coming into the unit with a test lamp or multimeter. Connect the multimeter or test lamp probe to the wire being tested and the other probe to ground. The black line should be “live”.
Optional Lifebreath Ventilation Control - Part #99-BC04 Key Features: 2 speed fan setting (LOW / HIGH) Standby setting (fan OFF) 20/40 mode Compatible with 99-DET02 Wireless Timers Slim-line design Connect to 3 wire 20 gauge low voltage wire ON/OFF Light ON/OFF Button BC02 Operating Instructions: Turning on the Control Press and release the ON/OFF button above will illuminate. .
Optional Lifebreath Wireless Timer - Part #99-DET02 The Timers may be installed onto a flush mounted electrical switch box or it may be surface mounted onto a wall. Multiple Timers may be installed in a ventilation system. To increase the range of a wireless Timer, a RX02 Repeater should be used. Pairing: 1. Turn on the main wall control by pressing the ON/ OFF button and remove the battery from Timer. 2. Press the left and right buttons simultaneously on the main wall control ( and ).
Optional Lifebreath Wireless Timer - Part #99-DET02 Installation of Wireless Timer 1. Separate the Face Plate from the Back Plate by firmly pulling apart (Figure A). 2. For mounting the control without a Decora plate, break off top and bottom tabs and refer to Figure C for mounting. 3. Place the Back Plate of the control in the desired location on the wall and pencil mark the top and bottom screw holes (Figure B or C). Drill two 1/8" holes. Back Plate 4.
Optional Lifebreath Wireless Repeater - Part #99-RX02 The RX02 Repeaters are to be plugged directly into a 120V power outlet 1. Turn on the main wall control by pressing the ON/OFF button . 2. Press the left and right buttons simultaneously on the main wall control ( and ). The bottom row of 3 LED's will begin flashing. This indicates that the main control is now in pairing mode. 3. The RX02 Repeater must be powered within 16” of the main wall control for pairing.
Function and Controls Basic Functions Setup Speed control is obtained by powering 24V to one of the designated speed taps. Select appropriate operational speed by installing the jumper wire between one of the designated speed taps. (A jumper wire is factory installed in the low speed position.) Example: A jumper between the R terminal and the G terminal will result in low speed operation.
Connecting Optional Control - Part #99-BC04 The control is to be surface mounted onto a wall. ! Only 1 master control should be installed to a ventilation system (the Face Plate on this illustration may not be exactly the same as yours). Figure B Figure A Back Plate Face Plate 1/8 in hole for screw and anchor 1 in x 3/4 in oval hole for wire opening 3. Place the Back Plate of the control in the desired location on the wall and pencil mark the top and bottom screw holes (Figure B or C). 4.
Pitot Tube Air Flow Balancing - Commercial It is necessary to have balanced air flows in an ERV. The volume of air brought in from the outside must equal the volume of air exhausted by the unit.
Service and Maintenance Servicing your ERV 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 be needed; whereas ventilating a meeting room for carbon dioxide may only need service every six months to a year.
Service and Maintenance Filters 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). Refer to ERV Core. The filters are designed to stop large particles from entering in the core. The filters are fastened in place by a metal spring rod. To remove filters from core(s) simply pull the rod from one end, outward until free from core lip, and remove.
Reverse Installation of the ERV Electrical Box Removal: Reinstalling the Electrical Box: Remove the door panels from the ERV by loosening the screws located on the face of the doors. Remove the electrical box cover by removing the 4 screws fastening the cover in place. 11. Install the two snap plugs in the cabinet holes on the side of the ERV which electrical box was originally removed from.
Aircom Relays The Aircom circuit board has three available “dry contact” relays. Contact 3 is not available. Maximum 115V 10 amp resistive load. Contact 2 and 4 These relays initiate whenever the ERV fans are operating. Aircom Relays Use contact 2 or 4 to interlock the ERV to an Air Handler or Furnace. Connecting the ERV as illustrated will ensure the Air Handler Blower Motor is operating whenever the ERV is ventilating.
