Annual Maintenance
WARNING ! !
Electrical shock hazard. Can cause
injury or death. Before attempting to
perform any service or maintenance,
always disconnect the unit from its
power source.
5. Cleaning the Fans - Fans may accumulate dirt causing an imbalance and/or excessive vibration on the HRV/ERV. A reduction in
the air flow may also occur. In new construction this may result within the first year due to heavy dust and may
occur periodically after that over time depending on the outdoor conditions.
• unplug the HRV/ERV
• open the service door
• remove the core
• disconnect the fan motor wires
• remove the screws securing fan assembly
• pull the fan assembly out of unit
• check for any accumulation on the blades
• clean with a small brush if necessary:
- scrub individual fan blades until clean
- vacuum and wipe
• put the components back in place
• reconnect the power supply and turn the unit back on.
