Energy Recovery Ventilator Maintenance


Your Energy Recovery Ventilator or ERV is an integral part of your home’s ventilation design. This new and innovative system provides state-of-the-art performance in high-rise residential condominiums. Simply put, your ERV allows better air quality by the delivery of fresh air directly into your home, while recovering 60% – 70% of the energy of your outgoing air.

How does it work?

In the winter, as warm, stale air is exhausted from your home, the heat from this air stream is used to warm the fresh, cold incoming air before it is distributed around the home. In summer, the cooler, air conditioned exhaust is used to cool the incoming fresh air and limits the amount of moisture transferred from the humid summer air. The two air streams share their energy so it saves you money while working to save the environment.

How to Operate:

Your energy recovery ventilator is controlled by a wall mounted Lite Touch Bronze Control which has four settings.ERV1

  1. Minimum – denoted by yellow indicator light is your recommended daily setting. This setting is low continuous and is the ideal suggested setting by the manufacturer for everyday operation. Air will move through the ERV at approximately 60 cfm or cubic feet per minute,
    ensuring a continuous fresh air supply throughout your home.
  2. Maximum –denoted by red indicator light is recommended for high occupancy or high pollutant homes. This high continuous setting is for suites with a large number of residents or pets or for when you have large parties or gatherings. It is for when you want stronger ventilation to manage pollutants like smoke or to mange your condensation. Your ERV at this setting will operate at 100 cfm.
  3. Recirculation – denoted by green
  4. Off – no indicator light which means your ERV is in a service mode. Used for when your ERV is being serviced or when you have open windows or doors that allow your home air movement and ventilation normally provided by your ERV.

Maintenance and Warranty

Through your builder, the ERV has a Two year warranty. However, some simple maintenance is required by you to keep your unit operating at peak efficiency. Without regular maintenance, the filters and core of the energy recovery ventilator can become clogged, limiting ventilation, air flow and air quality throughout your home.

Cleaning and Care for your ERV


Your filters should be cleaned every six months. We recommend you write
this on a calendar or consider it part of your spring and fall maintenance
program. To clean your filter, please follow these simple steps:ERV2

  1. Unplug your ERV.
  2. Unlatch the door and open it.
  3. Clean the inside of the door with a damp cloth, then wipe dry with a dry cloth. Lift both foam filter brackets and remove the foam filters from the core.
  4. Disengage the door from the hinge by sliding it from left to right and then set the door aside.
  5. Lift both foam filter brackets and remove the foam filters from the core. Reinstall the door.
  6. Clean the inside walls of the unit with a clean damp cloth, then wipe dry.
  7. Wash the 2 foam filters in a hot water and mild soap solution, rinse thoroughly and then let dry completely before reinstalling. To reinstall both filters, secure them to the core by pulling down the 2 foam filler brackets.
  8. Reinstall the door.


The core of your ERV should be cleaned once a year to ensure it does not become clogged with dust or other detritus.

  1. Unplug your ERV.
  2. Unlatch the door and open it.
  4. Using the soft brush attachment on your vacuum cleaner, gently vacuum any dust or debris from the core.
  5. When you have completed vacuuming the core, reinstall door.

Restarting Your ERV Unit:

If the unit was unplugged during maintenance, it will now reset and return to the previous setting after a 30 second delay.

If the unit was not unplugged during maintenance, the indicator light will flash RED. Press the reset button twice. The reset button is the small black button located beside the indicator light. The indicator light will flash several times before turning off. Once the indicator light is off, the Lite Touch wall control will be enabled.
