  • Page 5 Multi-Unit Residential ERV CAUTION Before installation, careful consideration must be given to how this system will operate if connected to any other piece of mechanical equipment that operates at a higher static, i.e., a forced-air furnace or air handler. After installation, the compatibility of the two pieces of equipment must be confirmed by measuring the airflows of the ERV using the balancing procedure found in this manual.

  • Page 6: Ducting Configurations

    Multi-Unit Residential ERV CAUTION This unit is intended for residential use only, conforming to the requirements of the International Residential, Building, and Mechanical Codes, NFPA 90B for the United States and the National Building Code of Canada. Turn the unit off during construction to avoid clogging the filters and loading the blowers with construction dust.
  • Page 7 This system is not connected to an Air-Handling Unit (AHU) or furnace. This system is normally balanced on high speed. If ALDES patented* Zone Register Terminals (ZRT®) are used for exhaust or supply registers, balancing must be done at normal operating speed.

  • Page 8: Locating The Air Exchanger

    Multi-Unit Residential ERV In warm, humid seasons, continuous operation of the AHU causes evaporation from the cooling coil, resulting in a loss of humidity control. Failure to operate the AHU with the ERV may also result in condensation in the supply plenum and ducting. Continuous operation of the AHU may cause drafts in the winter.

  • Page 9: Connecting The Ducts

    Multi-Unit Residential ERV Where the ducts remain permanently accessible, 5 to 10 feet of insulated flexible duct should be used between the ERV and all interior supply and exhaust registers to reduce fan noise passing the ducting to interior spaces. Connecting the Ducts For the air exchanger to run optimally, place the ducts so they are as straight as possible.

  • Page 10: Locating The Exhausr Air Grilles Or Registers

    Multi-Unit Residential ERV Exhaust Air Wall hoods: • At least 6 feet (2 metres) from the fresh air intake wall hood. • At least 18 inches (457 mm) above the ground, or above the depth of expected snow accumulation. • At least 3 feet (1 metre) from the corner of the building.

  • Page 11: Locating The Supply Air Grilles Or Diffusers

    Multi-Unit Residential ERV Adjustable grilles can be used to balance the flow rates. Field supplied balancing dampers can be external to the unit to balance the amount of stale air being exhausted. These grilles should not be adjusted after balancing the unit. Locating the Supply Air Grilles or Diffusers The fresh air diffusers should be installed in hallways, near the primary return for the forced air system, in bedrooms and/or in common living areas.

    Multi-Unit Residential ERV C) Interlocking the ERV to an Air-Handler/Furnace Blower Installations sharing ductwork with air-handling units or furnaces operate most effectively when those units are powered on to properly distribute the fresh air provided by the ventilator throughout the home. The ERV has the ability to interlock with external equipment, such as an air-handler or furnace blower, to activate or deactivate that equipment as necessary.

    Multi-Unit Residential ERV Excessive negative pressure may have several undesirable effects. In some geographic locations, soil gases such as methane and radon gas may be drawn into the home through basement/ground contact areas. Excessive negative pressure may also cause the backdrafting of vented combustion equipment.
