PROBLEMS SOLUTIONS POSSIBLE CAUSES
1. Air flow is low - HRV/ERV airflow improperly
balanced
- filter clogged
- core obstructed
- exterior fresh air supply blocked
- damper is closed (if supplied)
- ductwork is restricting
- power supply low (Low Voltage)
- have professional balancer or
contractor balance the unit
- remove and clean filter
- remove and clean core
- remove and clean the blockage
- check damper
- inspect duct installation
- switch off the unit immediately and
call the electrician to check the
voltage
Maintenance (cont’d)
Repeat steps 1 to 5 from the previous section and continue with the following steps:
1. Clean the HRV and ERV core:
- Remove filters
- Loosen the core locking bracket
- Remove the core, carefully grip ends of core and pull
evenly outward
-
HRV Core > remove dust using vacuum cleaner or
rinse with cold water
> Soak and rinse the HRV core in warm
soapy water
-
ERV Core > remove dust using vacuum cleaner
2. Motors - Maintenance Free, permanently lubricated
3. Drain Tube and Drain Pipe - Inspect drain tube, drain pipe and “P” trap for blockage, mold or kinks. Flush with
warm soapy water and replace if worn, bent or unable to clean.
4. Clean Duct Work if Required - Wipe and vacuum the duct once every year. The duct work running to and from
HRV/ERV may accumulate dirt. You may wish to contact a heating / ventilation
company to do this.
ATTENTION ! !
• Do not use cleaning solution for the HRV/ERV core
• Do not use pressure washer on the HRV/ERV core
• Do not place the HRV/ERV core in dishwasher
• Do not use bleach or chlorine
Annual Maintenance
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.
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.
